GlossaryProstaglandin D2 Synthase (PGD2 Synthase)

enzyme converting prostaglandin H2 to prostaglandin D2, linked to hair loss

Prostaglandin D2 Synthase (PTGDS) is an enzyme that converts prostaglandin H2 into prostaglandin D2 (PGD2), a lipid compound involved in various physiological processes, including inflammation and allergic responses. In the context of hair biology, elevated levels of PGD2 have been linked to hair loss, particularly in conditions like androgenetic alopecia.

18 citations, October 2021 in “Frontiers in Physiology”

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.
