unleashing treg cells may lead to treatments for multiple sclerosis

Sumary of Unleashing Treg cells may lead to treatments for multiple sclerosis:

  • In a new University of California, Irvine-led study, researchers found that a certain protein prevented regulatory T cells (Tregs) from effectively doing their job in controlling the damaging effects of inflammation in a model of multiple sclerosis (MS), a devastating autoimmune disease of the nervous system.
  • Published this month in Science Advances, the new study illuminates the important role of Piezo1, a specialized protein called an ion channel, in immunity and T cell function related to autoimmune neuroinflammatory disorders.
  • “We found that Piezo1 selectively restrains Treg cells, limiting their potential to mitigate autoimmune neuroinflammation,” said Michael D.
  • ” T cells rely on specialized proteins, like Piezo1, to detect and respond to various diseases and conditions including bacterial infections, wound healing, and even cancer.
  • Uncontrolled T cell activity, however, can give rise to autoimmune disorders in which the immune system attacks normal cells in the body.
  • Tregs constantly curate immune responses and play a critical role in preventing autoimmunity.
  • Research over the last decade has shed light on the role of Piezo1 in regulating vital physiological functions including red blood cell (RBC) volume, blood pressure, vascular development, bone formation, and differentiation of neural stem cells.
