释义 | Dendritic Cell,Follicular《英文msh词典》Dendritic Cell,Follicular [入口词] Dendritic Cell,Follicular [主题词] Dendritic Cells,Follicular [英文释义] Cells with extensive dendritic processes found in the B-cell areas (primary follicles and germinal centers) of lymphoid tissue. They are unrelated to the DENDRITIC CELLS associated with T-cells. Follicular dendritic cells have Fc receptors (RECEPTORS,FC) and C3b receptors (RECEPTORS,COMPLEMENT 3B),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.
