This indicated that more and more Aβ42 molecules in these groups were catalytically degraded by HS72 over time. This was particularly the case for the Aβ42O group (Fig. 2B). For example, after 1 and 10 days of incubation of Aβ42O with HS72, the levels of Aβ42 decreased by about 4.8% and 11.2%, respectively. Precisely, the difference in mean levels of the remaining Aβ42 between the corresponding groups incubated with HT7 and HS72 was what accounted for the true share of proteolytic degradation of Aβ42 catalyzed by HS72 (Fig. 2C). Evidently, HS72 catalyzed the degradation of Aβ42 chains in an Aβ42 aggregate unit in a catalytic duration-dependent way, which was identical to the catalytic properties of typical enzymes. For example, after 1 and 10 days of incubation with HS72, about 4.3% and 9.4% of Aβ42O were degraded, respectively. Further, the capability and efficacy of HS72 in catalyzing Aβ42O degradation were significantly higher than its capability and efficacy in catalyzing Aβ42F degradation, indicating that although Aβ42O tended to further aggregate into Aβ42F during the incubation, the target binding and catalytic effect of HS72 greatly reduced further aggregation of Aβ42O. As a result, in the presence of HS72, the degradation rate of Aβ42O was almost always substantially higher than that of Aβ42F (Fig. 2C). \", \"Analysis of Aβ42-associated components in the degradation of Aβ42 aggregates catalyzed by HS72 by western blotting, and HPLC.\", \"Figure 3\", \"Finally, HS72 catalyzed the degradation of Aβ42 chain(s) in Aβ42O* and yielded free ΔAβ or small ΔAβ-Aβ42 oligomers (Aβ42O#); and (2) the release of the product ΔAβ from Aβ42O* after HS72 catalysis, either in the free form or as small ΔAβ-Aβ42 oligomers, was accompanied by the dissociation of a corresponding amount of Aβ42M from Aβ42O*. It could thus be proposed that the degradation of (large) Aβ42O and Aβ42F catalyzed by HS72 yielded ΔAβ, Aβ42M, and Aβ42O# but no intact small Aβ42O.\", \"Additionally, almost no components with longer retention durations than small Aβ42O were found in the 1−10-day Aβ42M catalytic system (Fig. 3G), indicating that the induction and catalytic efficacy of HS72 together effectively inhibited or disrupted the greater aggregation of Aβ42.\", \"Overall, these results demonstrated that HS72 had a catalytic effect on Aβ42 aggregates, especially on Aβ42O, which was presumably attributed to two different residues in HS72: Asp45 and His241 (Fig. S1A).\", \"HS72 Significantly Reduces the Degree and Extent of Aβ42 Aggregation and Triggers a Specific Breakdown of Aβ42 Aggregates\", \"HS72 degraded approximately 5.6% of Aβ42 in the Aβ42O group within 48 h (Fig. 2C).\", \"Figure 5\", \"The fluorescence intensity in all four groups considerably decreased in the presence of scFv HT7 (gray diamonds), DS1 (black circles), and HS72 (black triangles) compared with the control (gray square), suggesting that scFv HT7, DS1, and HS72 could inhibit and/or prevent the assembly or aggregation of Aβ42 to some extent.

This showed that scFv HT7 could not only strongly inhibit further aggregation of the primary oligomeric Αβ42 aggregates, but also to a certain extent effectively reverse the formation, i.e., induced the disaggregation, of these Αβ42 aggregates, especially immature protofibrils.\", \" Finally, and strikingly, similar aggregation-inhibiting and disaggregation-inducing efficacy of scFv HT7 was also observed in Aβ42 fibrils. Although this did not reach significance (Fig. 3a(d)), it suggested that HT7 could also inhibit or even reduce the growth of Aβ42 fibrils to a certain extent, an effect that was barely observed for scFv MO6 (Zhang et al. 2015a).\", \"Electron microscopy further confirmed the inhibitory effect of scFv HT7 on Aβ42 aggregation 24 h after co-incubation with the four Aβ42 species (Fig. 3b). Aβ42 particles in the co-incubated Aβ42 monomer or oligomer reactions with scFv HT7 (Fig. 3b(b or d)) were much smaller than those in the corresponding controls (Fig. 3b(a or c)), indicating that scFv HT7 effectively repressed Aβ42 aggregation, while inducing their disaggregation into smaller oligomers.\", \"Taken together, the results shown in Fig. 3a, b demonstrated that scFv HT7 was not only able to inhibit Aβ42 aggregation but also to facilitate the gradual disassembly of oligomeric and even fibrillar Aβ42 aggregates into small Aβ42 oligomers in vitro.\", \"This enabled scFv HT7 to gradually induce the disaggregation of the larger Aβ42 aggregates as well as fibrils, while effectively inhibiting their further aggregation after recognizing and binding to the Aβ42 aggregates or fibrils. In particular, the specific recognition and the fitted binding of scFv HT7 to Aβ42 aggregates appeared to be a prerequisite for all the above effects of scFv HT7.\", \"This presumably occurred owing to the higher binding affinity of scFv HT7 to Aβ42 oligomers and protofibrils (Fig. 2) and the greater efficacy of scFv HT7 in inducing the disaggregation of Aβ42 oligomers and protofibrils (Fig. 3a, b).\", \"The presence of the hexameric complexes further indicated that once three scFv HT7 bound respectively to the three N-terminal regions of an Aβ42 trimer subunit, thus reaching scFv HT7 binding saturation, the bound scFv HT7s greatly attenuated the interaction of this Aβ42 trimer subunit with others and eventually led to the disassociation of the scFv HT7-saturated Aβ42 trimer subunit from larger Aβ42 aggregates or fibrils to release the non-cytotoxic hexameric complexes.\", \"In addition, in respect to scFv-induced disaggregation of Aβ42 aggregates, the manner of dissociating Aβ42 aggregates initially as Aβ42 trimer subunits, then into individual Aβ42 molecules appeared much more efficacious than that of dissociating Aβ42 aggregates directly into individual Aβ42 molecules one after another. Therefore, the efficacies of scFv HT7 in inducing the dissociation of Aβ42 aggregates as well as inhibiting Aβ42 aggregation, as shown in Fig. 3a, were significantly higher than those of scFv MO6 (Zhang et al. 2015a).\", \"In conclusion, this study revealed the subunit-assembly characteristics of Aβ42 aggregates and the post-saturation dissociation mechanism of the protective efficacy of an anti-oligomeric Aβ42 scFv antibody against the formation and cytotoxicity of oligomeric Aβ42 aggregates.\",", "Curator Statement": false }, "AMGAB0080": { "Interaction ID": "AMGAB0080", "Antibody ID": "ABID0131", "Antibody name": "6E10", "Amyloid ID": "AGAMYID0003", "Amyloid name": "Aβ-42", "DOI": "10.1007/s13346-022-01117-6", "PMID": 35015254.0, "Impact of the antibody on amyloid formation": "No effect", "Experimental Model(s)": "In vivo", "Experimental method(s)": "Immunohistochemistry, ELISA", "Amyloid species identified": "Protein monomer, Oligomers", "Antibody paratope, CDR, or Negative control": "No information provided", "Quote of the interaction": "\"Accumulation of Aβ (1–42) was induced in the brain of 15-month-old App KI mice; however, obvious changes in Aβ (1–42) disposition were not observed after intranasal or i.v. administration.\", \"Figure 4\",", "Curator Statement": "The authors refer to the antibody as A594-AntiAβ.

However, scFv HT6 showed the greatest efficacy in terms of both inhibiting development and inducing disassembly of aggregates in the Aβ42 protofibrils system within the first 3 h, despite a light increase in their aggregation after 3 h (Fig. 2c). Finally, scFv HT6 had a similar but weaker effect on Aβ42 fibrils as observed on Aβ42 oligomers (Fig. 2d), suggesting that scFv HT6 could also slightly inhibit the growth of Aβ42 fibers or even induce a slight decrease in their aggregation, especially during the first 12 h.\", \" Aβ42 particles derived from co-incubation of Aβ42 monomers or oligomers with scFv HT6 (Fig. 3b or d) were much smaller than their corresponding controls (Fig. 3a or c), indicating that scFv HT6 effectively repressed Aβ42 aggregation while inducing the disassembly of the aggregates into smaller oligomers to a certain extent. Similar to the results of the ThT-F assay, even shorter or finer Aβ42 protofibrils, along with some Aβ42 oligomers, were observed when Aβ42 protofibrils were co-incubated with scFv HT6 (Fig. 3f) compared to the unique state of the corresponding controls (Fig. 3e). This further demonstrated the greater efficacy of scFv HT6 in preventing the formation and stability of Aβ42 protofibrils. However, a mixture of diffuse and shorter or fine fibrillar states was observed when the Aβ42 fibrils were co-incubated with scFv HT6 (Fig. 3h) compared to their corresponding controls (Fig. 3g). These diffuse Aβ42 fibrils might represent the larger Aβ42–scFv HT6 complexes, from which the small Aβ42 oligomers might be subsequently dissociated out.\", \"For example, scFv HT6 had a slightly weaker effect on the aggregation of Aβ42 oligomers but had a stronger effect on the aggregation of Aβ42 protofibrils or even fibrils (Fig. 1c, Fig. 2) compared with scFv MO6. \", \"Moreover, scFv HT6 had greater potency than scFv MO6 in restraining the development of Aβ42 aggregates, although both antibodies reduced the aggregation of Aβ42 monomer with the same efficacy [8]. In particular, scFv HT6 more effectively suppressed the development of Aβ42 protofibrils rather than Aβ42 oligomers, indicating that the hydrophobic interaction between the C-terminal regions of smaller Aβ42 oligomer subunits (such as the trimer (3-mer)) was stronger for larger Aβ42 oligomer particles (such as octadecamer (18-mer)) than in Aβ42 protofibrils. Consequently, separation of the smaller Aβ42 oligomer subunits induced by scFv HT6 was more readily achieved from Aβ42 protofibrils than from larger Aβ42 oligomers because the scFv HT6-targeted region is relatively further from the C-terminus of Aβ42, even though scFv HT6 exhibited higher binding affinity for Aβ42 oligomers than scFv MO6.\", \"Figure 7\", \"This study demonstrated that the efficacy of an anti-oligomeric Aβ42 antibody to reduce the cytotoxicity of Aβ42 aggregates appears to be mainly related not only to its affinity for the Aβ42 aggregates, or to its efficacy of slowing or blocking the development of Aβ42 aggregates, but also, and potentially more importantly, to the specific antibody-targeted site or region on the Aβ42 aggregate and to the antibody's binding mode toward the Aβ42 aggregates based on their conformation fit.\",", "Curator Statement": false }, "AMGAB0149": { "Interaction ID": "AMGAB0149", "Antibody ID": "ABID0007.5", "Antibody name": "3D6", "Amyloid ID": "AGAMYID0002", "Amyloid name": "Aβ-40", "DOI": "10.1016/j.jalz.2012.11.010", "PMID": 23583235.0, "Impact of the antibody on amyloid formation": "Diminished amyloid quantity at the final point (partial inhibition)", "Experimental Model(s)": "In vivo", "Experimental method(s)": "Immunohistochemistry", "Amyloid species identified": "Not specified", "Antibody paratope, CDR, or Negative control": "VH-CDR1: GFSLSTSGMGVS, VH-CDR2: DNDRYYNPSLKS, VH-CDR3: PMNTWGDY, VL-CDR1: RSSQSLVHSNGNTYLH, VL-CDR2: KVSNRFSVL-CDR3: SQNTHVPLT", "Quote of the interaction": "\" After passive immunotherapy with 3D6, parenchymal Aβ and VAβ deposits were cleared in a time-dependent manner (Table 1).

For example, when HS72 acted in combination with Mat, Aβ42 levels decreased by 4.8%, 12.9%, and 9.6% in the Aβ42M, Aβ42O, and Aβ42F groups, respectively, whereas when HS72 acted alone, they decreased by 4%, 11.2%, and 5.8%, respectively. Clearly, Mat increased HS72's catalytic effectiveness for Aβ42 aggregates. The differences in the remaining Aβ42 levels in the three groups in the presence and absence of Mat are shown in Fig. 1B. The differences in all three groups increased with increasing catalytic duration, especially in the Aβ42F group, indicating that Mat synergized the catalytic effect of HS72 on Aβ42 aggregates, particularly Aβ42F.\", \"Figure 1\", \"In the Aβ42M group (Fig. 1C and D), in the presence of HS72 with Mat, the levels of the HS72−Aβ42 complex (c in Fig. 1C and D) and Aβ42M (including free Aβ42M and Aβ42M−Mat complexes, denoted by Aβ42M*) (f in Fig. 1C) remained constant during incubation from days 1–10 at 37 °C, whereas the levels of small Aβ42O, including free Aβ42O and Aβ42O−Mat complexes (e in Fig. 1C), gradually decreased with increasing catalytic duration.\", \"In contrast, in the Aβ42M incubation system without Mat, the level of the HS72−Aβ42 complex gradually decreased, and the level of Aβ42O gradually increased with increasing catalytic duration (Song et al., 2023). This implied that although Aβ42M tends to aggregate into Aβ42O during incubation at 37 °C, under the synergistic action of Mat, the newly formed Aβ42O were efficiently digested by HS72 and the degradation products (N-terminal and C-terminal Aβ fragments, denoted by NAβ and AβC, respectively, and not recognized by the used anti-Aβ42 primary antibody) were quickly released from the active site of HS72, which inevitably caused the disassembly or release of the remaining Aβ42 chains from the involved Aβ42O units.\", \"In contrast to when HS72 was used alone (gray triangles in Fig. 2A–D), the fluorescence intensity in all four groups significantly decreased in the presence of both HS72 and Mat (black circles). These results demonstrate that HS72 was more effective at blocking and reducing Aβ42 aggregation or assembly in the four groups when Mat was present, particularly in Aβ42O and Aβ42F groups where the degree of Aβ42 aggregation remained lower than that in their initial stage within this 48 h. Apparently, Mat's intervention in the integrated conformation of Aβ42 aggregates by inserting Aβ42 aggregate units as previously reported (Yang et al., 2020) considerably aided HS72's induction of Aβ42 aggregate disassembly or breakdown while aiding in Aβ42 aggregate degradation. This demonstrated that the degradation of the Aβ42 aggregate was accompanied by their disassembly or breakdown.\", \"Figure 2\", \"The presence of Mat promotes HS72-induced clearance of Aβ plaques in the brain of AD model mice\", \"Figure 5\", \"In the HS72 and HS72 with Mat groups (c and d in Fig. 5B), the level of hippocampus Aβ deposits/plaques decreased, and the spots were lighter in color and smaller in size. In contrast, the positive control group showed hippocampal regions with darker and larger Aβ spots (a in Fig. 5B, arrows). Furthermore, the HS72 with Mat group exhibited a reduced level of Aβ deposits/plaques than the HS72 group (c and d in Fig. 5B).\", \"HS72 and HS72 with Mat reduced a load of Aβ deposits and plaques in the hippocampal region by 27.4% and 34.3%, respectively, compared to the positive control (100%) (**p < 0.01, ***p < 0.001). Further, there was a significant difference in the load of Aβ42 deposits and plaques between the HS72 and HS72 with Mat groups (#p < 0.05) (Fig. 5C). However, there was no significant difference in the number of Aβ42 deposits and plaques between them (Fig. 5D), although there was a significant difference in the number of Aβ42 deposit/plaque spots between HS72 or HS72 with Mat group and the positive control group (**p < 0.01) (Fig. 5D). These results showed that after 7 days of peripheral administration, scFv HS72 combined with Mat was as effective as scFv HS72 alone in reducing the number of Aβ42 deposit/plaque spots in the brains of AD mice, and was also marginally superior to scFv HS72 alone in reducing the area or quantity of positive Aβ42 deposits/plaques. \", \"In addition, the results of Fig. 5 showed that the synergistic effect of Mat on scFv HS72 can increase the efficacy of HS72 in reducing the level of large Aβ42 aggregates, such as Aβ42F, besides enhancing the efficacy of HS72 in removing Aβ42O or small aggregates, which is consistent with the results shown in Fig. 1B.\", \"Therefore, the presence of Mat increased the efficiency of HS72 in degrading Aβ42 aggregates and altered the nature of the degradation products. \", \"In conclusion, Mat synergistically enhanced the ability of HS72, an catalytic anti-oligomeric Aβ42 scFv antibody, to degrade Aβ42 aggregates and protect neural cells by increasing HS72's turnover number (or molecular activity). The combination of scFv HS72 with Mat reduced or removed Aβ42 aggregates or plaques more effectively than HS72 alone, which will increase scFv HS72's potency in AD immunotherapy.\"", "Curator Statement": "Authors refer to monomers as Aβ42M, oligomers as Aβ42O , protofibrils as Aβ42P and fibrils as Aβ42F." }, "AMGAB0250": { "Interaction ID": "AMGAB0250", "Antibody ID": "ABID0310", "Antibody name": "B06 IgG", "Amyloid ID": "AGAMYID0003", "Amyloid name": "Aβ-42", "DOI": "10.1016/j.neuroscience.2021.03.006", "PMID": 33958140.0, "Impact of the antibody on amyloid formation": "Slower aggregation (partial inhibition), Diminished amyloid quantity at the final point (partial inhibition),", "Experimental Model(s)": "In vitro", "Experimental method(s)": "ThT - Aggregation kinetics", "Amyloid species identified": "Oligomers", "Antibody paratope, CDR, or Negative control": "No information provided", "Quote of the interaction": "\"Figure 6\", \"However, SPR measurements revealed insufficient binding affinity of each recombinant antibody B06, B07 and C06.

This was confirmed by TEM imaging (Supporting Figure 3b); by 30 h, oligomers are rarely observed in the Aβ42 sample, corresponding to the elongation phase, and only sparsely observed at 48 and 72 h, the plateau phase. In contrast, if Aβ42 is incubated with anti-AβOcSNK, oligomers are readily found at 48 h, the beginning of the plateau phase; by 72 h, oligomers are sparsely observed (Supporting Figure 3b). Similarly, when the presence of soluble versus insoluble aggregates in the assay was investigated through the time course, it was clear that anti-AβOcSNK delays the formation of insoluble aggregates by at least 20 h (Supporting Figure 3).\", \"Supporting Figure 3\", \"Anti-AβOcSNK markedly delays the aggregation of Aβ into an insoluble aggregate.\", \". Aβ gradually converts to its insoluble form starting at 30 h in the absence of antibody, while anti-AβOcSNK retains it in its soluble form for a longer time (> 48 h). IgG1 seems to have an effect, but the delay is less pronounced than with anti-AβOcSNK (between 30 and 48 h)\", \"These TEM and ThioT analyses indicate that anti-AβOcSNK inhibits the aggregation of Aβ polymers in vitro, displaying its most prominent effects in early stages. In the lag phase as monomers begin to form oligomers, the cSNK epitope is exposed and is subsequently bound by anti-AβOcSNK. This binding slows the accumulation of β-sheet and oligomeric structures; likewise, this blockade slows the transition from oligomers to fibrils as the majority species in the population. However, once a critical concentration of oligomers (including protofibrils) has been reached, the elongation phase begins, in which fibrils recruit monomer at a faster rate than oligomers. (54) Thus, in the elongation phase, anti-AβOcSNK has a reduced impact because fibrils do not display the cSNK epitope. Finally, a significant reduction in plateau β-sheet structure suggests that, by maintaining some structures in an oligomeric form, the anti-AβOcSNK antibody has a negative downstream effect on total Aβ fibril content in vitro and perhaps even in vivo (Supporting Figure 5b).\", \"Figure 6\", \"Twelve month-old male Tg2576 and APP/PS1 mice were intraperitoneally injected weekly with 30 mg/kg of anti-AβOcSNK for 6 weeks.

This indicates that 20–30% of the total brain AβO population can form AβOcSNK and are thus sensitive to engagement by anti-AβOcSNK and subsequent clearance. Notably, the murine IgG1 Fc subclass of the anti-AβOcSNK monoclonal antibody necessitates that clearance occur without the participation of Fc receptor-bearing brain cells, such as microglia.\", \"This is also supported by the in vitro aggregation study, which shows that anti-AβOcSNK (1) blocks formation of soluble oligomers from monomers, (2) has a nonsignificant effect on elongation of fibrils, and (3) reduces the maximal β-sheet produced (Figure5).

Moreover, 4396C often remained bound to the fibril edge for more than 100 s, effectively arresting the fibril elongation (Figure 6b).

These data demonstrate the formation of B10-epitopes at significant level before the formation of ThT-positive fibrils. TEM analysis demonstrates small amounts of nonfibrillar aggregates after 4 h, large quantities of fibrils after 18 h, and both fibrils and nonfibrillar structures after 7 h (Fig. 4a). The apparent quantity of the nonfibrillar aggregates declines progressively upon incubation.\", \"Addition of B10AP to Aβ(1–40) at 1:10 (B10:Aβ) molar ratio potently blocks the formation of ThT-positive fibrils (Fig. 4b) and leads, instead, to the stabilization of much more irregular, curvilinear fibrils, similar to what has been described as protofibrils (35, 36). The presently analyzed fibrils possess amyloid-like characteristics, evident from an ATR-FTIR peak at 1,624 cm−1 (Fig. 4c) and x-ray diffraction (Fig. 4d). Fully hydrated protofibril-B10AP complexes show reflections at 4.62 ± 0.02 and 9.88 ± 0.05 Å, the characteristic spacings of an amyloid-like core structure (5). Nevertheless, protofibril-B10AP complexes show only small interactions with amyloid-specific dyes, such as ThT or CR (Fig. 4 e and f), consistent with previous reports about Aβ protofibrils (37). Control reactions show that their small ThT and CR affinities cannot be explained with a steric hindrance due to B10AP or with a short fibril length, because B10AP-decorated mature fibrils and fragmented mature fibrils (Fig. 4g) produce significant interactions with both dyes (Fig. 4 e and f). Protofibril-B10AP complexes are more susceptible toward proteolytic digestion than mature fibrils (Fig. 4h), consistent with a lower structural compactness. Taken together, we conclude that B10AP prevents the formation of mature Aβ amyloid fibrils by arresting fibril formation at the protofibril stage.\", \"Experiments in which B10AP is added to Aβ peptide under the conditions of fibril formation show that B10AP possesses functional activity in abrogating the formation of mature amyloid fibrils (Fig. 4).\",", "Curator Statement": false }, "AMGAB0478": { "Interaction ID": "AMGAB0478", "Antibody ID": "ABID0523", "Antibody name": "AB10", "Amyloid ID": "AGAMYID0002", "Amyloid name": "Aβ-40", "DOI": "10.1073/pnas.0703793104", "PMID": 18042730.0, "Impact of the antibody on amyloid formation": "No effect", "Experimental Model(s)": "In vitro", "Experimental method(s)": "ThT - Aggregation kinetics, TEM image in presence/absence of the antibody, Digestion experiments by proteinase K, X-ray fiber diffraction pattern, Increase in beta content by Fourier transform infrared (FTIR) spectroscopy, Ultracentrifugation, Congo Red (CR) red shift,", "Amyloid species identified": "Protofibrils, Mature fibrils", "Antibody paratope, CDR, or Negative control": "No information provided", "Quote of the interaction": "\"Finally, centrifugation (Fig. 4i) and TEM analysis (not presented) do not provide evidence that B10AP binding leads to a significant disaggregation of preformed Aβ fibrils. \", \"Figure 4\", \"Consistent with this, we do not observe any significant dissociation of preformed amyloid fibrils in the presence of B10AP (Fig. 4i).\",", "Curator Statement": "The AB10 construct does not dissagregate preformed fibrils." }, "AMGAB0479": { "Interaction ID": "AMGAB0479", "Antibody ID": "ABID0135", "Antibody name": "C4", "Amyloid ID": "AGAMYID0008", "Amyloid name": "Huntingtin (htt) Fusion construct", "DOI": "10.1073/pnas.071058398", "PMID": 11296304.0, "Impact of the antibody on amyloid formation": "Diminished amyloid quantity at the final point (partial inhibition)", "Experimental Model(s)": "In cellulo", "Experimental method(s)": "Other: Flourescence microscopy", "Amyloid species identified": "No information provided", "Antibody paratope, CDR, or Negative control": "No information provided", "Quote of the interaction": "\"Coexpression of anti-huntingtin sFv intrabodies with the abnormal huntingtin-GFP fusion protein dramatically reduced the number of aggregates, compared with controls lacking the intrabody. \", \"Figure 4\", \"\"Up to 86% fewer aggregates were present in intrabody cotransfectants, compared with control levels\", \"When this HD model is examined in transfected cells, the huntingtin analogues with expanded polyglutamine (polyQ) repeats exhibit visible aggregate formation that increases proportionately with the number of glutamine residues in the polyQ segment.

The data are well fitted assuming a selective reduction of k2 (Fig. 3) but cannot be fitted at all if only kn (SI Appendix, Fig. S2), or only k+ (SI Appendix, Fig. S3), is varied. The strongest inhibitory effect of these scFvs is thus likely to be on secondary nucleation, whereas primary nucleation and elongation remain essentially unaffected, in agreement with the scenario shown in Fig. 2B. The fits to the data at the higher scFv concentrations indicate a very low value of k2. The effect saturates at ∼1–2 µM scFv in solutions containing initially 3 µM Aβ42 monomers, suggesting that secondary nucleation is effectively completely suppressed in the presence of high concentration of these scFvs, and the secondary nucleation rate is much lower than the primary nucleation rate essentially during the full time course of the aggregation reaction.\", \" The scFv I2 appears to have somewhat lower affinity (SI Appendix, Fig. S1), and at the highest concentrations used, its inhibitory effect corresponds to ca. 20-fold reduction in k2, thus some secondary nucleation still occurs at a detectable rate. \", \"We find that the fibril-specific scFvs from clones I2, I48, J44, and J57 most likely inhibit Aβ42 aggregation through selective reduction of the rate constant for secondary nucleation. In the presence of scFvs I48, J44, and J57 at molar ratios above ca. 1:2 scFv:Aβ42, secondary nucleation has no detectable kinetic significance, although for I2 there is a residual contribution from this microscopic step.\", \"Figure 5\", \" However, scFvs I2, I48, J57, and J44 diminish this seeding effect (Fig. 5 A–D) and 1% and 3% seeds have much lower catalytic effect than for Aβ42 alone. The aggregation in the presence of these scFvs is dominated by primary nucleation and still very strongly retarded relative to the behavior observed in the absence of scFv. At 30% seed, the aggregation kinetics of Aβ42 in the absence of scFv is greatly accelerated due to rapid elongation of the seeds, seen as the emergence of observable growth from time 0 (Fig. 5 E and F). The growth rate at early times can reveal effects on the elongation rate constant, and we find that I2, I48, J57, and J44 cause at most a factor of 1.3 change in this rate (Fig. 5 F and G), compared with the more than 10-fold (I2) or more than 100-fold (I48, J44, and J57) reduction in the rate constant for secondary nucleation (Figs. 3 E and F and 5G).\",\"Indeed, if the sites for secondary nucleation and elongation were to be identical, it would not be possible to block selectively secondary nucleation without affecting elongation and vice versa. The scFvs I2, I48, J44, and J57 act in a manner similar to Brichos, which binds along the fibril surface (21) and blocks selectively secondary nucleation. These scFvs are likely to bind to epitopes presented along the sides of the fibrils in a manner that prevents Aβ42 monomer binding or nucleation. The scFvs I68 and J7 are intriguing in that they seem to show a duality of behaviors, with selective inhibition of secondary nucleation processes at low concentration, whereas at higher concentrations the elongation step also appears to be affected (Fig. 4 A and B and SI Appendix, Fig. S5).\",\"Starting from large phage display libraries of single-chain antibody fragments (scFvs), the three-stage approach that we describe includes (i) selection of scFvs with high affinity for Aβ42 fibrils after removal of scFvs that bind Aβ42 in its monomeric form; (ii) ranking, by surface plasmon resonance affinity measurements, of the resulting candidate scFvs that bind to the Aβ42 fibrils; and (iii) kinetic screening and analysis to find the scFvs that inhibit selectively the fibril-catalyzed secondary nucleation process in Aβ42 aggregation.\", \"By applying this approach, we have identified four scFvs that inhibit specifically the fibril-dependent secondary nucleation process.\", \"These macroscopic aggregation curves are clearly affected by all four scFvs but not by randomly selected scFvs from the initial pool (Fig. 4 D and E).\", \"Figure 3\", \"Figure 4\", \"As a consequence of secondary nucleation inhibition, the reactive flux is redirected to a pathway including primary nucleation and elongation only. This means that a much smaller number of new aggregates are created (Fig. 2E) and a larger fraction of monomers are consumed in elongation of those fewer aggregates, leading to longer fibrils on average.\", \"Secondary nucleation is a positive feedback mechanism that can lead to the rapid amplification of the number of aggregates once an initial population has been formed (20, 22) and also be very effective in the production of toxic oligomers (20, 21).

Importantly, our approach allows scFvs that inhibit elongation to be detected and eliminated from further investigations, as such species can cause significant apparent inhibition of the overall aggregation reaction but are unlikely to result in a significant reduction of toxic species and could even lead to an increase in the overall production of oligomers.\", \"Figure S5\"", "Curator Statement": false }, "AMGAB0549": { "Interaction ID": "AMGAB0549", "Antibody ID": "ABID0009.9", "Antibody name": "m11-1F4", "Amyloid ID": "AGAMYID0009", "Amyloid name": "Antibody Light chain", "DOI": "10.1073/pnas.1805515115", "PMID": 30377267.0, "Impact of the antibody on amyloid formation": "Diminished amyloid quantity at the final point (partial inhibition),", "Experimental Model(s)": "In vivo", "Experimental method(s)": "Fluorescence microscopy, Immunohistochemistry, Other amyloid-staining dyes (Proteostat, Th-S, hFTAA, Bis-ANS, ...)", "Amyloid species identified": "No information provided", "Antibody paratope, CDR, or Negative control": "No information provided", "Quote of the interaction": "\"Pretreatment with the peptope induced 11-1F4 mAb accumulation in serum amyloid A deposits in vivo and enhanced 11-1F4–mediated dissolution of a human AL amyloid extract implanted in mice.\", \"Finally, we demonstrate enhancement of 11-1F4 mAb-mediated clearance of implanted human AL amyloid extract in a model of localized AL amyloid in the presence of peptope.\", \"Female NU/NU mice (∼8 wk of age) were injected subcutaneously on day 0 with 2 mg of human AL λ2BAL amyloid labeled covalently with Dylight800 (DL) NIR fluorophore and with (n = 5) or without (n = 4) preincubation in 200 µg of p66.

In addition, using single-molecule fluorescence measurements we have identified a selective action of the nanobodies at the earliest stages of the aggregation reaction associated with the formation of toxic oligomeric species. In particular, both nanobodies were found to slow down the conformational conversion from less stable low-FRET oligomers to more stable high-FRET oligomers.

When both high- and low-doses of BACE inhibitor are compared with combination with gantenerumab, a statistically significant (p < 0.001) decrease of plaque numbers are seen in cortex and hippocampus.
