CCR3signalinginEosinophils

Eosinophils are a key class of leukocytes involved in inflammatory responses, including allergic reactions in skin and airway. The eosinophil response in inflammation is absent in mice lacking CCR3, indicating the key role of this G protein coupled receptor in inflammation and allergic responses. Eotaxin is a chemokine ligand for CCR3 that recruits eosinophils to the site of inflammation and activates them. Other che......阅读全文
