Immunophenotypic analysis of blood and spleen lymphocyte subsets in rats protected against schistosomiasis by cyclosporin A.

abstract：:Several recent studies have shown that the antigen receptors (mIgM and mIgD) on normal B cell surfaces are part of larger multimolecular complexes, as each is noncovalently coupled to at least two other proteins whose phosphorylation is inducible upon G protein activation. However, B cell receptor complexes appear to ...
