IL10
IL-10 is an anti-inflammatory interleukin, produced mainly by monocytes. It is responsible for down-regulating the synthesis of pro-inflammatory cytokines like IFN-γ, IL-2, IL-3, TNFα (Th1 cytokines), class II MHC, and co-stimulatory molecules on macrophages. IL-10 also displays potent abilities to suppress the antigen presentation capacity of APCs (Antigen Presenting Cells), and it is also responsible for enhancing B cell survival, proliferation and antibody secretion. In this scenario IL-10 favors Th2 response (Mocellin et al 2004, Elenkov & Chrousos, 1999).
Some studies suggested that IL-10 acts as immunoregulator in intestinal tract. For example Steidler et al (2000) used a genetically modified Lactococcus lacti expressing IL-10 to treat mice with Inflammatory Bowel Disease (IBD), and the inflammatory response signals were reduced in 50%. IBD is an autoimmune disease which, unlike the immune response found in intestinal tract due to stress, involves a Th1 polarization and inflammation.
