FAQS
| Description |
|
IL-7 (interleukin-7) is a 25 kDa cytokine of the hemopoietin family that plays important roles in lymphocyte differentiation, proliferation, and survival. Human IL‑7 cDNA encodes 177 amino acids (aa) that include a 25 aa signal peptide. Human IL-7 shares approximately 60-63% aa sequence identity with mouse, rat, canine and feline IL-7, and 72-76% with equine, bovine, ovine, and porcine IL-7. Human and mouse IL-7 exhibit cross-species activity. IL-7 is produced by a wide variety of cells in primary and secondary lymphoid tissues, including stromal epithelial cells of the thymus, bone marrow, and intestines. Circulating IL-7 is limiting in healthy animals, but increases during lymphopenia. IL-7 signals through a complex of the IL-7 Receptor alpha subunit (IL-7 R alpha, also known as CD127) with the common gamma chain ( gamma c). The gamma c is also a subunit of the receptors for IL-2, -4, -9, -15, and -21. |
