title: Transgenic analysis of thymocyte signal transduction.
abstract: This review examines the value of transgenic studies in mice for the genetic dissection of signal-transduction pathways relevant to thymus development. T-cell development in the thymus is controlled by an ordered sequence of differentiation and proliferation checkpoints that culminate in the production of correctly selected, non-autoreactive, peripheral T lymphocytes. Work in transgenic mice has been fundamental for the preparation of genetic maps of signal-transduction pathways that control T-cell development. This review discusses how tyrosine kinases, guanine-nucleotide-binding proteins and transcription factors converge to control T-cell differentiation and proliferation in the immune system.
