Researchers traced an immune pathway from brain-draining lymph nodes to tau-affected tissue, revealing how peripheral immune activity may become intertwined with neurodegeneration. Study: Priming of CD8+ T cells by peripheral dendritic cells exacerbates tau-mediated neurodegeneration. Image Credit: Antonio Marca / Shutterstock
