Background
Interleukin 11 (IL-11) is a cytokine, encoded by the gp130 family genes. IL-11 initially thought to be important for hematopoiesis, notably for megakaryocyte maturation, and it facilitate the formation of higher order structures involving dimers of gp130: IL-11:IL-11 RA complexes.
Synonyms
Adipogenesis inhibitory factor, AGIF, Interleukin-11
