Description
CR2 is expressed strongly on mature B cells, follicular dentritic cells and weakly on immature thymocytes and T lymphocytes. CR2 functions as a receptor for C3d, C3dg and iC3b Complement components and for EBV and for IFN alpha. Follicular dendritic cells (contained in B cell follicles) selectively express the “Long” isoform of CR2 (CD21L) that contains an additional exon (10a) compared to CR2 (CD21). R4/23 recognises the long form of CR2 and can be used to identify dendritic reticulum cells (or their remnants) in lymphoid tissues.
