IL-7 plays a key role in lymphopoiesis and lymphoid homeostasis. Stromal and epithelial cells within the bone marrow and thymus produce IL-7. The primary targets of IL-7 are T cells, B cells, and dendritic cells. IL-7 is crucial for T cell development, the importance of which is underscored by the lack of T cells in both mice and humans that are deficient in IL-7/IL-7R signaling. While IL-7 appears to be required for B cell development in mice, the role of IL-7 in human B cell development is unclear. In addition to its effects on T cell lymphopoiesis, IL-7 promotes the maintenance and survival of naïve and memory αβ T cells, as well as γδ T cells. The IL-7 receptor is a heterodimer of the common γ chain, γc, and the IL-7-specific IL-7Rα. IL-7 activates PI3K/Akt, Jak1/2, and Stat1, 3, and 5.

This protein is a cytokine important for B and T cell development. This cytokine and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. This cytokine is found to be a cofactor for V(D)J rearrangement of the T cell receptor beta (TCRB) during early T cell development. This cytokine can be produced locally by intestinal epithelial and epithelial goblet cells, and may serve as a regulatory factor for intestinal mucosal lymphocytes. Knockout studies in mice suggested that this cytokine plays an essential role in lymphoid cell survival.
Hematopoietic growth factor capable of stimulating the proliferation of lymphoid progenitors. It is important for proliferation during certain stages of B-cell maturation.
