Study Notes
Regulation of Inflammation
- IL-10 down-regulates the responses of activated macrophages in the inflammatory response.
Genetic Disorders and Inflammation
- IL-10 receptor deficiency is a rare inherited disease that leads to severe colitis in infancy.
Cytokines in Tissue Repair
- TGF-β is a mediator of fibrosis in tissue repair after inflammation.
Characteristics of Inflammation
- Chronic inflammation is characterized by a mononuclear infiltrate, in contrast with acute inflammation.
Negative Regulation of Inflammation
- Intracellular proteins, such as SOCS (Suppressor of Cytokine Signaling), inhibit pro-inflammatory signals triggered by receptors recognizing microbes and cytokines.
