CC   -!- FUNCTION: Major immune regulatory cytokine that acts on many cells of
CC       the immune system where it has profound anti-inflammatory functions,
CC       limiting excessive tissue disruption caused by inflammation.
CC       Mechanistically, IL10 binds to its heterotetrameric receptor comprising
CC       IL10RA and IL10RB leading to JAK1 and STAT2-mediated phosphorylation of
CC       STAT3. In turn, STAT3 translocates to the nucleus where it drives
CC       expression of anti-inflammatory mediators. Targets antigen-presenting
CC       cells (APCs) such as macrophages and monocytes and inhibits their
CC       release of pro-inflammatory cytokines including granulocyte-macrophage
CC       colony-stimulating factor /GM-CSF, granulocyte colony-stimulating
CC       factor/G-CSF, IL-1 alpha, IL-1 beta, IL-6, IL-8 and TNF-alpha.
CC       Interferes also with antigen presentation by reducing the expression of
CC       MHC-class II and co-stimulatory molecules, thereby inhibiting their
CC       ability to induce T cell activation (By similarity). In addition,
CC       controls the inflammatory response of macrophages by reprogramming
CC       essential metabolic pathways including mTOR signaling (By similarity).
CC       {ECO:0000250|UniProtKB:P18893, ECO:0000250|UniProtKB:P22301}.
CC   -!- SUBUNIT: Homodimer. Interacts with IL10RA and IL10RB.
CC       {ECO:0000250|UniProtKB:P22301}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P22301}.
CC   -!- SIMILARITY: Belongs to the IL-10 family. {ECO:0000305}.
