Interleukin 36 gamma (IL-36 gamma) is a 17.65 kDa cytokine with 159 amino acid residues. IL-36 gamma is a member of the IL-1 family and is mainly expressed in keratinocytes, bronchial epithelial cells, macrophages, and monocyte. This cytokine responds to multiple pathogen-associated molecular patterns (PAMPs) and participates in the inflammatory response. In addition, it also induces the production of pro-inflammatory cytokines like IL-12, IL-1β, IL-6, TNF-α, and IL-23.
