Human Interleukin 17F (IL17F) Protein

Background

Interleukin-17F (IL17F) is a member of the IL-17 cytokine family, which plays a pivotal role in regulating inflammatory responses and bridging the innate and adaptive immune systems. IL-17F is closely related to IL-17A, the founding member of the family, and shares functional similarities with it. Both IL-17F and IL-17A are secreted primarily by T-helper 17 (Th17) cells, a subset of CD4+ T-cells involved in immunity against extracellular pathogens, especially fungi and bacteria. In addition to Th17 cells, IL-17F can also be produced by other cell types such as natural killer (NK) cells, innate lymphoid cells (ILCs), and neutrophils. IL-17F is implicated in several immune-mediated processes, including the promotion of inflammation in tissues. It is primarily associated with the pathogenesis of autoimmune diseases such as psoriasis, asthma, and inflammatory bowel disease (IBD).
