| Summary |
IL22 plays a role in mucosal immunity where it helps constrain inflammation and protect mucosal sites.
IL22 is a member of the IL-10 cytokine family that is produced by special immune cell populations and ts primary effects on target cells include its role in innate immune defence against infections, in tumourigenesis, and in inflammatory diseases.
IL22 increases the TNF-alpha-dependent induction and secretion of several immune-modulatory molecules such as initial complement factors, antimicrobial peptides and chemokines in primary keratinocytes. IL22-mediated induction of innate immunity is crucial for the maintenance of epidermal integrity during infection with Candida albicans.
IL22 is produced by lymphoid tissue-inducer cells where it regulates the maintenance of colonic lymphoid structures during Citrobacter rodentium infection, a mechanism that bridges the lymphotoxin pathway to mucosal epithelial defense mechanisms. (Demonstrated in mice)
IL22 protects intestinal stem cells from inflammatory tissue damage and regulates sensitivity to graft versus host disease.
Stat3 mediates protection against intestinal infection by inducing innate lymphoid cell derived-Il22. (Demonstrated in mice)
IL22 protects against and IL22RA2 aggravates liver fibrosis and cirrhosis in chronic liver infections.
IFNG interferes with the IL-1/NFKBIZ axis in β-glucan-activated dendritic cells and promotes T cell-mediated immune responses with increased release of IFNG and IL22, and diminished production of IL17A.
In alveolar epithelium, IL22 upregulates DEFB4A gene expression via STAT3.
IL22 induced at an early stage of L. monocytogenes infection enhances innate immunity against L. monocytogenes in the liver by stimulating hepatocytes to produce an antimicrobial molecule, PLA2G2A

| Summary |
[Mus musculus] Iltifb (Il22b) increases the TNF-alpha-dependent induction and secretion of several immune-modulatory molecules such as initial complement factors, antimicrobial peptides and chemokines in primary keratinocytes. Iltifb-mediated induction of innate immunity is crucial for the maintenance of epidermal integrity during infection with Candida albicans. (Demonstrated in human)
[Mus musculus] Iltifb (Il22) is produced by lymphoid tissue-inducer cells where it regulates the maintenance of colonic lymphoid structures during Citrobacter rodentium infection, a mechanism that bridges the lymphotoxin pathway to mucosal epithelial defense mechanisms.
[Mus musculus] ILTIFB (IL22) protects intestinal stem cells from inflammatory tissue damage and regulates sensitivity to graft versus host disease. (Demonstrated in human)
[Mus musculus] Flagellin induces Tlr5-dependent Il22 production and Nlrc4-dependent Il18 production to promote a protective gene expression program in intestinal epithelial cells and elimination of rotavirus-infected cells.
[Mus musculus] Cxcl16-Cxcr6 crosstalk coordinates the intestinal topography of Il22 secretion required for mucosal defence against Citrobacter rodentium infection.
[Mus musculus] Il22 augments the expression of Il18 mRNA and inactive precursor protein (proIL-18) in intestinal epithelial cells after Toxoplasma gondii or Citrobacter rodentium infection and maintains the homeostatic amount of proIL-18 in the ileum.
[Mus musculus] Innate lymphoid cells, potent producers of Il22 after intestinal injury, increase the growth of mouse small intestine organoids in an Il22-dependent fashion.
[Mus musculus] Group 3 innate lymphoid cells (ILC3s) can mediate immune surveillance, which constantly maintains a proper microbiota, to facilitate early colonization resistance through an Id2-dependent regulation of Il22.
