Technical Data
CCR3 (CD193, CC Chemokine Receptor Type 3, CC CKR 3, CC CKR3, B Chemokine Receptor, CMKBR3, Eosinophil CC Chemokine Receptor 3, Eosinophil Eotaxin Receptor, MGC102841)
CCR3, a Chemokine Receptor, was cloned from Human eosinophils (Daugherty et al., 1996). This receptor binds specifically the chemokine eotaxin and activates eosinophil leukocytes. CCR3 also responds to a variety of beta-chemokines (CC motif) including RANTES, monocyte chemotactic proteins, and mucosae-associated epithelial chemokine (MEC). CCR3 is a key mediator of allergic reactions; activation of this receptor stimulates the production of interleukins required for activation of basophils and eosinophils (Sallusto et al., 1997). CCR3 plays a role in the progression and pathogenesis of inflammatory diseases such as asthma, multiple sclerosis, and Alzheimer's disease. This receptor also facilitates HIV-1 penetration in heart and brain. CCR3 has been reported in blood, brain, lung, bone marrow, kidney, liver, lymph node, placenta, skin, spleen, thymus, thyroid, uterus, and vessel. Within these tissues, CCR3 is expressed in specific cell types, including eosinophils, basophils, Th2 cells, and mast cells.
