Lymphoid cell populations in various organs of the carp Cyprinus carpio L. were investigated using a series of mouse monoclonal antibodies raised against carp thymocytes and carp serum Ig. Clones have been designated as Ig+T+, Ig+T- or Ig-T+ on the basis of the reactivity with thymocytes and serum Ig in the enzyme-linked immunosorbent assay (ELISA) screening. Their reaction to the lymphoid organs of carp was investigated on cryostat sections and cytocentrifuge slides using immunoperoxidase techniques. IG+T+ clones could be subdivided into those that stained reticular fibres around blood vessels in various organs (R+) and those that did not (R-). The former stained most thymocytes and most peripheral lymphocytes as well as plasma cells whereas the latter did not stain cortical thymocytes and some peripheral lymphocytes. IG+T- clones were negative for thymocytes but positive for plasma cells and a certain population of peripheral lymphocytes. Ig-T+ clones reacted similarly to Ig+T+R- clones. It is concluded that fish lymphoid cell populations can be distinguished based upon differences in cell surface and/or cytoplasmic determinants. The monoclonal antibodies described can be used for further structural analysis of the determinants and for functional separation of T- and B-like cells in the 'lower' vertebrates. |
