Detection of IL‑22 in Mouse Th17 Splenocytes by Flow Cytometry. Mouse splenocytes (A) differentiated to Th17 cells with plate-bound Rat anti-Mouse CD3e monoclonal antibody (MAB484, 10 µg/mL) plus Goat anti-Mouse CD28 (AF483, 5 µg/mL), Recombinant Human TGF-beta 1 (100-B, 10 ng/mL) Recombinant Mouse IL-23 (1887-ML, 20 ng/mL), Recombinant Mouse IL-6 (406-ML, 40 ng/mL), Recombinant Mouse IL-1 beta (401-ML, 10 ng/mL), and Rat anti-Mouse IFN-gamma (MAB485, 10 µg/mL) for 6 days then re-stimulated with PMA (50 ng/ml), Ca2+ Ionomycin (200 ng/ml) and Brefeldin A ( 5 μg/ml) for 4 hours, or (B) resting, were stained with APC-conjugated Rat anti-Mouse CD4 Monoclonal Antibody (FAB554A) and Rat Anti-Mouse IL-22 Monoclonal Antibody (Catalog # MAB582) followed by PE-conjugated Goat anti-Rat secondary antibody (F0105B). Quadrant markers were set based on isotype control antibody (MAB006). To facilitate intracellular staining, cells were fixed and permeabilized with FlowX FoxP3/Transcription Factor Fixation & Perm Buffer Kit. (FC012).

Background: IL-22
Interleukin-22 (IL-22), also known as IL-10-related T cell-derived inducible factor (IL-TIF) was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. Mouse IL-22 cDNA encodes a 179 amino acid (aa) residue protein with a putative 33 aa signal peptide that is cleaved to generate a 147 aa mature protein that shares approximately 79% and 22% aa sequence identity with human IL-22 and IL-10, respectively. The mouse IL-22 gene is localized to chromosome 10. Although it exists as a single copy gene in many mouse strains, the IL-22 gene is duplicated in some mouse strains including C57B1/6, FVB and 129. The two mouse genes designated IL-TIF alpha and IL-TIF beta, share greater than 98% sequence homology in their coding region. IL-22 has been shown to activate STAT-1 and STAT-3 in several hepatoma cell lines and upregulate the production of acute phase proteins. IL-22 is produced by normal mouse T cells upon Con A activation. Mouse IL-22 expression is also induced in various organs upon lipopolysaccharide injection, suggesting that IL-22 may be involved in inflammatory responses. The functional IL-22 receptor complex consists of two receptor subunits, IL-22R (previously an orphan receptor named CRF2-9) and IL-10R beta (previously known as CRF2-4), belonging to the class II cytokine receptor family.
