TLDR People with Alopecia areata have higher levels of prostaglandin D2 in their blood and tissues.
In 2019, researchers Abd-ElRaheem, El-Tahlawy, Shaker, Mohamed, and Soliman conducted a study to estimate the levels of serum prostaglandin D2 and its expression in the tissue of individuals with Alopecia areata. The study found that there was a significant increase in the levels of serum prostaglandin D2 in patients with Alopecia areata compared to the control group. Additionally, the expression of prostaglandin D2 in the tissue of these patients was also significantly higher. These findings suggest that prostaglandin D2 may play a role in the pathogenesis of Alopecia areata.
