follicular dendritic cell morphology trait
type: Class
subclass of: immune system cell morphology trait
definition: Any measurable or observable characteristic related to the shape, structure, color, or pattern of a cell with extensive dendritic processes found in the B cell areas (primary follicles and germinal centers) of lymphoid tissue; follicular dendritic cells have Fc receptors and C3b receptors, and hold antigen in the form of immune complexes on their surfaces for long periods and can present antigen to B cells during an immune response.
has_obo_namespace: Trait.ontology
id: VT:0008196
comment: Follicular dendritic cells are a distinct population from other dendritic cells associated with T cells. Follicular dendritic cells have Fc receptors and C3b receptors, but unlike other dendritic cells, they do not process or present antigen in a way that allows recognition by T cells. Instead, they hold antigen in the form of immune complexes on their surfaces for long periods and can present antigen to B cells during an immune response. They are not derived from the hematopoietic lineage. Due to its unique lineage and distinct function (B cell vs. T cell presentation), this is NOT a type of dendritic cell.
