Interleukin 38 (IL-38) belongs to the IL-1 family and is expressed in fetal skin, spleen, and tonsils, predominantly in the basal epithelium of the skin and in proliferating B cells of the tonsils.IL-38 binds soluble IL-1 receptor type 1 and may be involved in the modulation of adaptive and innate immune responses. Alone, it does not induce cytokine production but decreases T-cell production of heat-inactivated Candida albicans IL22 and IL17A.IL-38 decreases IL36γ -induced IL8 production by peripheral blood mononuclear cells and increases IL6 production by bacterial lipopolysaccharide (LPS)-stimulated dendritic cells.

Recombinant Human IL-38 is a 16.9 kDa protein containing 152 amino acid residues. This Recombinant Human IL-38 is supplied as Lyophilized powder with high activity, high purity, low endotoxin, and NO labeling.
