CX3CL1 (fractalkine)-CX3CR1 interface drives CD8⁺ T cell-induced neurodegeneration in human brain organoids.
Immune-neuron interactions play a critical role in neuroinflammatory and neurodegenerative diseases, such as Alzheimer's disease (AD), but how CD8⁺ T cells contribute to brain pathology remains poorly understood. Amyloid-β (Aβ), a hallmark of AD, is known to trigger neuronal stress and inflammation. Here, we establishe...
