Peripheral dendritic cell priming drives CD8+ T cell–mediated tau neurodegeneration

A tauopathy mouse study shows conventional dendritic cell 1 (cDC1)–dependent cross-presentation of brain-derived antigens in peripheral lymphoid tissues primes CD8+ T cells that infiltrate the brain and worsen tau-related neurodegeneration; removing cDC1s or disrupting cross-presentation protects against neuronal loss and reduces brain T cell accumulation, highlighting a peripheral brain–immune axis as a potential therapeutic target.

SORLA protein slows tau-driven brain damage in Alzheimer's model mice

Researchers show that upregulating the brain protein SORLA in tauopathy mice lowers tau tangles and brain atrophy, preserves synapses and plasticity, and reduces harmful gene activity in glial cells; SORLA deficiency worsens damage, suggesting SORLA as a therapeutic target and hinting that drugs targeting plexin-B receptors could be repurposed for tau-related dementias.

Brain Switch Uncovered That Could Prevent Alzheimer’s Memory Loss

Brain Switch Uncovered That Could Prevent Alzheimer’s Memory Loss

UCSD researchers used an AI-driven approach to identify chromogranin A as a molecular switch deciding whether Alzheimer’s pathology translates into memory loss. In tauopathy mice, removing CgA preserved learning and memory despite brain pathology, with females showing stronger protection. They also found catestatin, a peptide derived from CgA, which lowered disease markers and protected cognition across several mouse models. All findings are preclinical and require replication, dosing, safety studies, and regulatory review before any human testing, but the work aims to shift Alzheimer’s research toward prevention-based strategies.
