Cytokine receptor signaling plays an essential role in the early stages of lymphocyte development. Signals through various cytokine receptors - such as c-kit, flt3/flk2, CXCR4, the IL-7 receptor and the IL-15 receptor - are known to promote the expansion and survival of uncommitted progenitor cells as well as their migration to the appropriate microenvironment and subsequent differentiation into B, T or natural killer cells. The recent generation of mice deficient in one or more of these signaling pathways has revealed which cytokines play unique and/or redundant roles in each of these lymphocyte lineages during this developmental process.
