METRNL

Short description: Mammalian protein found in Homo sapiens

Meteorin-like/Meteorin-Beta (Metrnl)/IL-41, also known as subfatin and cometin, is a small (~27kDa) secreted cytokine, protein encoded by a gene called meteorin-like (METRNL). METRNL is highly expressed in mucosal tissues, skin and activated macrophages.^[1]^[2]^[3] Metrnl has also been described to be a hormone^[4]

A screen of human skin-associated diseases showed significant over-expression of METRNL in psoriasis, prurigo nodularis, actinic keratosis and atopic dermatitis. METRNL is also up-regulated in synovial membranes of human rheumatoid arthritis.^[2]

Adipocyte Metrnl antagonizes obesity-induced insulin resistance by improving adipose function, including adipocyte differentiation, metabolism activation, and inflammation inhibition^[5] Lower serum levels of Metrnl might be a risk factor for developing coronary artery disease and type 2 diabetes mellitus^[6]^[7]

Function

Metrnl participates in the control of inflammatory responses^[3] and is a critical regulator of muscle regeneration.^[8]
