ABSTRACT:
A new B-cell receptor, Bp50, a 50 kilodalton polypeptide, that functions in B-cell proliferation is described. Ligands such as lymphokines, antibody molecules or the Fv fragments of antibody molecules that bind to Bp50 and augment the proliferation of activated B-cells can be used to regulate B-cell proliferation or differentiation.
