Prostaglandin-H2 D-Isomerase (PTGDS) Antibody

Background

Prostaglandin D2 Synthase (PTGDS) is an enzyme that catalyzes the isomerization of prostaglandin H2 (PGH2) to prostaglandin D2 (PGD2), a key lipid mediator involved in sleep regulation, allergic inflammation, vasodilation, and immune modulation PTGDS is highly expressed in the brain, heart, and male reproductive organs, where it participates in cerebrospinal fluid production, detoxification of free radicals, and maintenance of male fertility PGD2 plays a central role in allergic reactions, mediating bronchoconstriction in asthma and inflammation in rhinitis Dysregulation of PTGDS contributes to neurological disorders such as Alzheimer’s disease by facilitating tau phosphorylation, amyloid deposition, and oxidative stress PTGDS also serves as a biomarker for cardiovascular disease, brain injury, and central nervous system inflammation Its role in lipid signaling and antioxidant defense highlights its importance in both homeostasis and disease progression
