PTGDR2 Antibody

PTGDR2 Antibody: The prostaglandin D2 receptor 2 (PTGDR2), also known as CRTH2, is expressed on Th2 cells and eosinophils and mediates chemotaxis of these cells to PGD2 and is thus thought to be a key receptor mediating eosinophil and Th2 recruitment during allergic responses. However, PTGDR2-null mice showed enhanced eosinophil recruitment into the lung consistent with observations that the PTGDR2-null mice produced significantly higher amounts of interleukin-5 (IL-5) and IL-3. This suggests that PTGDR2 plays a nonredundant role in restricting eosinophilia and allergic response in vivo.
