Abstract

We have produced bcl-2 transgenic mice by using a construct which mimics the t(14;18) translocation in human follicular lymphomas. Although lymphoid tissues from all transgenic mice contained high levels of human Bcl-2 protein, transgene expression was differentially regulated within the B- and T-cell compartments of lines derived from various founder mice. We have characterized the phenotypes of two lines of bcl-2 transgenic mice (line 2 and line 6) in which bcl-2 transgene expression was restricted primarily to the T- or B-cell lineages, respectively. Analysis of line 6 lymphocytes revealed a polyclonal expansion of B cells, and these B cells exhibited prolonged survival in vitro. In line 2 mice, numbers of T cells in the peripheral lymphoid tissues were more moderately elevated despite enhanced T-cell survival in vitro. Line 2 transgenic mice also showed significantly increased proportions of thymocytes with a mature phenotype. Taken together, these findings suggest different roles for bcl-2 in the in vivo regulation of B- and T-cell development and homeostasis.
