WebDec 6, 2024 · Abstract Purpose: Food allergy is a hypersensitive immune response to specific food proteins. Chitinase 3-like 1 (CHI3L1, also known as YKL-40 in humans or BRP-39 in mice) is associated with various chronic diseases, such as cancer, rheumatoid arthritis, and allergic disease. WebFeb 15, 2024 · Humans also express chitinases, but also chitinase-like proteins that modulate immune responses. In particular, elevated levels of the chitinase-like protein YKL-40 are associated with severe asthma and cystic fibrosis. Chitinases and chitinase-like proteins (CLPs) belong to the family of glycosidic hydrolases 18 (GH18).
