Expression of v-rel induces mature B-cell lines that reflect the diversity of avian immunoglobulin heavy- and light-chain rearrangements.

ABSTRACT

The infection of newly hatched chickens with reticuloendotheliosis virus strain T (REV-T) and a nonimmunosuppressive helper virus, chicken syncytial virus, induces rapidly metastatic B-cell lymphomas. In vivo analysis of these tumors with monoclonal antibodies detected the expression of the B-cell surface markers immunoglobulin M (IgM), CIa, Bu2, and CLA-1, but not IgG, Bu1, or a T-cell surface marker, CT-1. Cell lines derived from tumors exhibited the same pattern of staining, suggesting that expression of cell surface markers does not change during in vitro cell line development. All cell lines examined synthesized IgM in varying amounts. Northern (RNA blot) analysis confirmed abundant expression of v-rel mRNA, and Southern analysis revealed rearrangement of both heavy- and light-chain immunoglobulin loci. Analysis of the light-chain locus demonstrated that 20 of 22 lines contained a single rearranged allele. With respect to specific restriction enzyme sites within the V lambda 1 gene, the active allele in any given clone was either diversified or nondiversified. In contrast, examination of the heavy-chain loci within these lines demonstrated that 16 of the 22 had both alleles rearranged. Further diversification of the V lambda 1 locus did not occur after prolonged in vitro passage of the cell lines. We propose that v-rel expression arrests diversification of the light-chain locus in these lymphoid cells, allowing the production of stable, clonal B-cell populations. The development of these and similar cell lines will make it possible to identify specific stages of avian lymphoid ontogeny and to study the mechanism of rearrangement and diversification in the avian B lymphocyte.
