Pgd2 is a lipid of Fatty Acyls (FA) class. Pgd2 is associated with abnormalities such as Inflammatory disorder, Pleurisy, Rhinitis, Dehydration and Pneumonia. The involved functions are known as antagonists, fat cell differentiation, Phosphorylation, Process and Gene Expression. Pgd2 often locates in Cell surface, Body tissue, Extracellular, Bone Marrow and Membrane. The associated genes with PGD2 are oxytocin, 1-desamino-(O-Et-Tyr)(2)-, P4HTM gene, PTGS2 gene, PTGDS gene and IL3 gene. The related lipids are 15-deoxyprostaglandin J2, Nonesterified Fatty Acids, Lipopolysaccharides, Steroids and Liposomes. The related experimental models are Knock-out and Rodent Model.
