The guinea pig leucocyte common antigen (LCA), expressed on different hemopoietic cells, was examined using the monoclonal antibody (mAb) H 201. Immunohistology and FACS analysis revealed that T and B lymphocytes, macrophages, and thymocytes express the H 201 epitope in comparable density. The level of LCA-expression increased during the course of maturation and activation of T cells. Differences in the molecular weight of LCA were observed, which depended on the nature of various cell populations, indicating that in each case alternative variants of LCA are expressed. The molecular weight of guinea pig LCA ranged from 175 kDa on thymocytes, up to a 230-kDa variant found on B lymphocytes. Antigen- or alloantigen-induced T cell activation in vitro was moderately affected by the continuous presence of mAb 201. In contrast, the PHA-mediated T cell proliferation was strongly and selectively enhanced, supporting the assumption of an LCA involvement in the "alternative pathway" of T cell activation.
