Biochem/physiol Actions

Interleukin-7 is a lymphoid cell growth factor which affects pre-B, pro-B and early T cells. It was first isolated by Namen in 1988. IL-7 has a number of known activities. It supports the growth of early B cells from long-term lymphoid bone marrow cultures. It is mitogenic for thymocytes and co-mitogenic with PHA and Con A. IL-7 also stimulates the proliferation of CD4/CD8 cells. The proliferative response of thymocytes to IL-7 is not affected by antibodies to the T cell growth factors such as IL-2, IL-4, and IL-6. Mature T cells respond to IL-7 and Con A, but not to IL-7 alone. Antibodies against IL-2 affect its activity, suggesting that it functions through IL-2 production. Human natural IL-7 is 25 kDa glycoprotein that has 6 cysteine residues which are important for biological activity. Human and mouse IL-7 have 60% amino acid sequence homology.

Interleukin Family (IL)

The Interleukins comprise a disparate group of cytokines and growth factors that are produced by and released from leukocytes. Interleukin-1β (1L-1β) is released primarily from stimulated macrophages...
