Induction of Phenotypic Lymphocyte Differentiation in LPS Unresponsive Mice by an LPS-Induced Serum Factor and by Lipid A-Associated Protein

Abstract
Summary: Spleen cells from C3H/HeJ mice are known to be unresponsive to mitogenic stimulation by LPS. We show here that T and B cell precursors of C3H/HeJ mice are unresponsive to induction of differentiation by LPS. Phenotypic differentiation of C3H/HeJ lymphocytes can be induced with DB-cAMP, Lipid A-associated protein, and with a serum factor induced by LPS in LPS responder strains.
