The two major subsets of T lymphocytes, helper and cytotoxic T cells, are defined by expression of CD4 and CD8 glycoproteins, respectively. T cells expressing the CD4 surface antigen facilitate B-cell maturation and production of antibodies by B-cells and are thus termed helper T cells. CD4+ helper T cells recognize exogenously derived peptides in the context of MHC class II molecule expressed on antigen presenting cells. One (D1) of four Ig-like extracellular domains of CD4 primarily interacts with the alpha2 and beta2 domains of the MHC class II heterodimer. This antibody, raised against antigens from Ginbuna carp, permits flow cytometric and immunofluorescence analysis of CD4 helper T cells from zebrafish, goldfish and the cyprinid fish carp.
