Study finds that plant extract called ObHEx activates receptor Piezo1, which detects mechanical forces in body. Activation is regulated by protein MYLK, and the extract contains components Liriodendrin and Salvadoraside, highlighting potential use of natural extracts to activate Piezo1.
This study looked at the effects of two plant extracts, Oenothera biennis and Hypericum perforatum, on brain tissue in mice with multiple sclerosis (MS). The extracts were found to decrease myelin loss, a hallmark of MS, and amyloid deposition on vascular walls. The extracts also improved antioxidant levels and decreased oxidative stress in the brain tissue of the mice. The study suggests that Oenothera biennis and Hypericum perforatum have potential therapeutic benefits for MS treatment.
