Evidence that Lyb-5 is a differentiation antigen in normal and xid mice
H R Smith et al. J Immunol. 1986.
Abstract
These studies addressed the question of whether the Lyb-5 determinant on mouse B cells might represent a marker for a unique lineage of B cells as has been thought, or rather, a differentiation antigen. Previous studies have addressed this question by treating splenic B cells with anti-Lyb-5 + complement and then culturing them with various antigens. In this study, we first immunized in vivo or in vitro and then determined susceptibility to anti-Lyb-5. These studies demonstrate that a substantial proportion of antibody-forming cells produced in response to immunization with sheep red blood cells, trinitrophenyl (TNP)-keyhole limpet hemocyanin, TNP-Brucella abortus, TNP-lipopolysaccharide, as well as TNP-Ficoll, are eliminated by anti-Lyb-5 + complement treatment at the end of culture. Some generation of Lyb-5+ antibody-forming cells occurred in the last 24 hr of culture. These studies suggest that the Lyb-5 marker represents a differentiation antigen on relatively mature B cells.
