Rubicon modulates neuroimmune responses following traumatic brain injury

Sagarina Thapa, Amir A. Mehrabani-Tabari, Olivia Pettyjohn-Robin, Dexter PH Nguyen, Mehari M Weldemariam, Chinmoy Sarkar, Maryam Khan, Maureen A. Kane, Marta M. Lipinski

This study shows that Rubicon promotes neuroinflammation and oxidative stress after traumatic brain injury by affecting autophagy and ROS production, and suggests it as a potential therapeutic target.
