Interleukin 10 is a ternary complex that requires specific assembly for proper function. The IL-10 complex is composed of IL-10,IL-10R1,IL-10R2. The initial step is the formation of IL-10 and IL-10R1 generating a conformational change that is required for IL-10R2 to be able to associate and form the ternary complex [1]. The completed complex activates the JAK/STAT signaling pathway.
The completion of the ternary complex is dependent on the conformational changes that occur in the N-Terminus of the helix labelled A. The conformational changes occur when the cIL-10 binds with IL-10R1. There is a positional change of about 1 angstrom at residues between Cys-12 and Leu-46. Due to the

Interleukin-10 is in the class cytokine.[1] Interleukin-10 is a very powerful anti-inflammatory cytokine that is most commonly found to be produce by moncytes [2]. IL-10 has the ability to be a immunosupressive as well as a anti-angiogenic this means that it has the ability both promot and inhibit tumors[3]. There are many types of cytokines that have many funtions such as from antiinflammatory cytokines,cytokine synthesis inhibitory factor and proinflammitory cytokines[4].
There are many interleukins that fall within the cytokine class such as IL-1,IL-2,IL-3,IL-4...IL-31,IL-32,IL-33,IL-3 and IL-35.

Interleukin-10 and Rheumatoid ArthritisInterleukin-10 and Rheumatoid Arthritis
IL-10 is investigated for its role in patients with Rheumatoid Arthritis (RA) as well as those with Osteoarthritis (OA)[4].
RA is an autoimmune disorder that affects the synovial tissues via chronic synovitis. Chronic synovitis often results in joint destruction due to re-absorption of bone and the distruction of cartilageCite error: Invalid parameter in <ref> tag.
