Interleukin-38 (IL-38) is a cytokine with a molecular weight of 16.87 kDa, consisting of 152 amino acid residues, and belongs to the interleukin-1 (IL-1) family. IL-38 is primarily secreted by basal epithelial cells of the skin, as well as by B cells in the tonsils, spleen, and thymus. Upon binding to receptors such as IL1RAPL1 and IL-36R, IL-38 plays a crucial role in inflammation and host defense by mediating the NF-κB, AP-1, and JNK signaling pathways. Furthermore, IL-38 is involved in downregulating cell proliferation and migration, while upregulating the expression of IL-6 and IL-10.
