title: Effects of V lambda gene diversity on generation of antigen-specific lymphocytes.
abstract: Previous studies have shown that dextran B1355 (DEX)- and (4-hydroxy-3-nitrophenyl) acetyl (NP)-coupled antigens triggered, respectively, BALB/c and C57BL/6 (B6) lymphocytes in which the V lambda 1 gene and a specific VH gene (VHDEX and VHNPb) have functionally rearranged. In this paper, we studied whether the closely-related V lambda 2 gene can be utilized in association with these VH genes to generate antigen-specific lymphocytes. We found that the VHDEX gene was restrictedly utilized by the V1 lambda 1 gene to generate anti-DEX lymphocytes, and in contrast, both the V lambda 1 and V lambda 2 genes were utilized together with a VHNPb germline gene to form anti-NP lymphocytes. Southern blot and DNA sequencing of an anti-NP hybridoma confirmed that the germline form of the (186-2) VHNPb gene can be used in association with either the V lambda 1 or V lambda 2 genes.
