Brain inflammation triggers muscle weakness after infections
Washington University in St. Louis

Research from Washington University School of Medicine in St. Louis reveals how brain inflammation triggers extreme muscle weakness across several diseases, including viral infection, bacterial infection and Alzheimer’s disease. The study, in fruit flies and mice, also identified ways to block this process, which could have implications for treating or preventing the muscle wasting sometimes associated with inflammatory diseases, including bacterial infections, Alzheimer’s disease and long COVID.
