Geng Geng et al. (2020) confirmed the protective function of HPS on the hippocampus of rats with cerebral ischemia-reperfusion injury, and IL-6, TNF-α, and IL-10 levels in the brain tissue of rats significantly decreased after administration of 200 mg/kg of HPS for 10 days. This evidence concerns the gene TNF and Hermansky-Pudlak syndrome.
