Antibody repertoire and gene expression profile: implications for different developmental and functional traits of splenic and peritoneal B-1 lymphocytes.


In L2 mice, a high expression level of the transgenic lambda2(315) L chain results in nearly complete exclusion of endogenous L chains and a predominance of B-1a cells. In this study, we show that splenic and peritoneal B-1a cells differ considerably in their Ab repertoire and gene expression profile. Splenic B-1a cells exhibit a more diversified repertoire… (More)
