Recombinant Human IL-6 Protein

Interleukin 6 (IL-6) is produced by fibroblasts, monocytes, macrophages, T lymphocytes, B lymphocytes, epithelial cells, keratinocytes and various tumor cells. IL-1, TNF-α, PDGF, viral infection, double stranded RNA, and cAMP can all induce  normal  cells  to  produce  IL-6.  IL-6  can  stimulate  the  proliferation,  differentiation  of  immune  responses  and improve immune cell functions. IL-6R is widely expressed on the surface of activated B cells, quiescent T cells, NK cells, myeloma cells, hepatocytes, and myeloid leukemia cells. The main role of IL-6 is to promote the proliferation and differentiation of B cells and the secretion of antibodies. It also has extensive effects on liver cells, T cells, neural tissue, and hematopoietic system. IL-6 also has anti-tumor effects and can directly or indirectly enhance the tumoricidal activity of NK cells and CTL.
