Researchers at the University of Lausanne have discovered a critical new role for the TDP-43 protein in controlling microglia, the brain's immune cells. When TDP-43 is lost in microglia, it disrupts myelin—the protective coating around nerve fibers—leading to motor deficits in mice. This finding, published in Nature Neuroscience, provides important insights into how protein dysfunction in brain immune cells may contribute to neurological diseases. Understanding this mechanism could open new therapeutic approaches for conditions affecting motor function and neurological health.
