Recent findings out of Washington University School of Medicine in St. Louis found that in mice studies, “targeting T cells is an alternative route to preventing neurodegeneration and treating Alzheimer’s disease and related diseases involving tau, collectively known as tauopathies.” According to the study’s senior author, David M. Holtzman, before this study, researchers were unclear about whether T cells cause neurodegeneration. However, with this new knowledge, “This could really change the way we think about developing treatments for Alzheimer’s disease and related conditions.”
