4. Interleukins 6, 7, 8, 9, and 10

Interleukin 6 or B-cell stimulatory factor 2 is involved in various biological functions. Some of these roles include the final differentiation of B cells into immunoglobulin secreting cells, differentiation of nerve cells, inducing plasmacytoma or myeloma growth, and more. Interleukin 7 functions as a growth factor for both B and T-cell lineages. Interleukin 8 is produced by endothelial cells, epithelial cells, airway smooth muscle cells, and macrophages. It functions as a mediator of the immune reaction in an innate immune system response. Interleukin 9 supports the growth of T-helper cells. Interleukin 10 functions to inhibit the production of interleukin 2, 3, interferon gamma, tumor necrosis factor, and more.
