Flow cytometric analysis of IL-22 expression in human PBMC polarized with Th1 Polarization Kit, Human (UA090016). Th1 polarized human PBMC were harvested and restimulated for 5 hr with PMA and Ionomycin in the presence of Brefeldin A (right Panel) or unstimulated (left Panel).
The cells were harvested and fixed with 4% PFA and permeabilized with Intracellular Fixation & Permeabilization Buffer Set. The cells were then stained with Phycoerythrin Mouse Anti-Human CD4 and SDT Biotin Mouse Anti-Human IL-22 Antibody at 1.25μl/test followed by Sav-iFluor 488. Total viable cells, as determined by Fixable Viability Dye 452 (S0D0021), were used for analysis. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.

Background
Interleukin-22 (IL-22) is a 20 kDa α-helical cytokine of the IL-10 family that is produced chiefly by activated innate lymphoid cells, Th17, Th22 and γδ T cells, signals exclusively through a heterodimeric receptor complex of IL-22R1 and IL-10R2 to activate STAT3 and, to a lesser extent, STAT1 and STAT5, and functions as a frontline defender of barrier organs by up-regulating antimicrobial peptides (e.g., β-defensins, RegIIIγ), mucins and tight-junction proteins, stimulating epithelial proliferation and survival, while simultaneously suppressing inflammatory cytokine release from tissue-resident immune cells, thereby orchestrating tissue repair, containment of commensal microbes and protection against extracellular bacterial and fungal pathogens; however, its dysregulation contributes to psoriasis, inflammatory bowel disease, fibrosis and certain cancers, making it a key target for therapeutic modulation.
