Mitochondrial carbonic anhydrase-VB inhibition rescues brain endothelial stress and memory in Alzheimer's disease models.

Inhibiting mitochondrial CA-VB prevents endothelial stress and preserves memory in AD models, with 3xTg mice showing reduced caspase activation and maintained cognitive function.

• Why it matters: Cerebrovascular and mitochondrial dysfunction are early contributors to AD progression, and targeting these pathways may offer new therapeutic avenues for this devastating disease.
• What they did: Researchers used pharmacological and genetic methods to inhibit CA-VB in human cerebral microvascular endothelial cells and AD mice, assessing effects on mitochondrial health, inflammation, and memory.
• The result: CA-VB inhibition prevented Aβ-induced endothelial apoptosis, barrier loss, and inflammation, ultimately preserving memory in AD mice, suggesting a promising strategy against cerebrovascular and cognitive decline.
