Within the aging brain, fragments of our own genetic past — long-dormant sequences known as jumping genes — are awakening in the presence of disease, producing molecules that the immune system mistakes for viral threats. Researchers at UT Health San Antonio have traced this molecular confusion to the toxic protein tau, linking it to the inflammation that quietly destroys neurons in Alzheimer's disease and progressive supranuclear palsy. The discovery reframes neurodegeneration not merely as a protein accumulation problem, but as a case of the body's defenses turning against a self it can no lo
