| Background |
Interleukin 19 (IL-19) predicts a molecular mass of 35.8 kDa, is a type of anti-inflammatory cytokine. It promotes the Th2 T-cell response which supports an anti-inflammatory lymphocyte phenotype, dampens the Th1 T-cell response and IFNγ secretion, increases IL-10 expression in peripheral blood mononuclear cells, and inhibits the production of IgG from B cells. |
| Synonyms |
interleukin 19, IL19 |
