Human anti Bovine Interleukin-22, clone AbD20463 recognizes bovine interleukin-22 (IL-22).

IL-22 is a T and NK cell cytokine, a member of IL-10 cytokine family and is expressed by mitogen activated bovine peripheral blood γδ T cells. IL-22 is rapidly produced by splenic cells and can be produced by Th17 cells. IL-22 takes part in regulating the immune responses of adaptive and innate immune systems.

Human anti Bovine Interleukin-22 has been successfully used to analyze IL-22 expression in PBMC from M. bovis. – infected cattle. Bovine tuberculin induced IL-22 and IL-17A production in M. bovis. infected cattle was observed in both CD4+ T cells and γδ T cell populations (Steinbach et al. 2016).
