the gamma chain regulates what
the development, survival, proliferation, differentiation and or function of multiple immune cell types
what shape is the IL-6
helical
IL-6 subunits
gamma chain, gp130 and the IL-6 R alpha chain
what secretes IL-6
macrophages and other cells
what does IL-6 stimulate
acute phase protein synthesis, production of neutrophils, regulates inflammation
what diseases are IL-6s involved in
rheumatoid arthritis, multiple sclerosis, systemic lupus, prostate cancer, and multiple myeloma
what role does IL-6 have in cancer
chronic inflammation and in regulating tumor microenvironments and metastasis
what drugs are progressing for anti-IL-6
