  "account": "A new study, led by scientists at Washington University School of Medicine, may have uncovered where and how immune cells drive Alzheimer's-like neurodegeneration. The research, published in Nature Neuroscience, reveals that T cells in the brain receive instructions from lymph nodes outside the brain. The team found that eliminating dendritic cells from the lymph nodes and other brain locations reduced elevated levels of T cells in the brain and associated damage, even without changes in tau tangle levels. This suggests that halting T cell activity could potentially slow or reduce cognitive decline in tauopathies like Alzheimer's. The findings highlight a new therapeutic pathway that may allow treatment without directly entering the central nervous system. Next, the team will investigate ways to impede dendritic cell function in midlife to mirror the onset of tau protein tangles and explore methods to identify the specific signals used by T cells to target the brain.",
  "summary": "A study in mice traces immune cells that drive neurodegeneration to the body’s lymph nodes, suggesting that processes outside the brain contribute to the damage seen in various tauopathies. The post Immune Cells Driving Alzheimer’s-Like Neurodegeneration Traced to Lymph Nodes appeared first on GEN - Genetic Engineering and Biotechnology News .",
