General description
IL-22 is a member of the IL-10 family of regulatory cytokines which includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26. Members of this family share partial homology in their amino acid sequences, but they are dissimilar in their biological functions. Produced by T lymphocytes, IL-22 inhibits IL-4 production by Th2 cells, and induces acute phase reactants in the liver and pancreas. IL-22 signals through a receptor system consisting of IL-10R?/CRF2-4 and IL-22R, both of which are members of the class II cytokine-receptor family. Recombinant human IL-22 is a 33.6 kDa non-disulfide-linked homodimeric protein containing of two 147 amino acid polypeptide chains.
Biochem/physiol Actions

Physical form
Lyophilized from 10 mM NaCitrate, pH 4.0.
Reconstitution
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.5-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Five novel cytokines (IL-19, IL-20, IL-22 (IL-TIF), IL-24 (human MDA-7, mouse FISP, rat C49A/Mob-5), and IL-26 (AK155)) demonstrating limited primary sequence identity and probable structural homology to IL-10 have been identified. These cellular cytokines, as well as several cytokines encoded

The interleukin (IL)-23/IL-17A/IL-22 cytokine axis plays a critical role in the pathogenesis of psoriasis, wherein IL-22 effects on epidermal alternations by inhibiting differentiation and inducing keratinocyte proliferation. In this study, we investigated effects of curcumin on IL-22-induced proliferation in a

Interleukin-22 (IL-22) has been recently highlighted owing to its biological significance in the modulation of tissue responses during inflammation. However, the role of IL-22 in carcinogenesis has remained unclear. Here, we investigated the pathophysiological significance of IL-22 expression in gastric
