Description

Jie Sheng and others show, in a 2026 study, that a frontotemporal dementia mutation in a mitochondrial protein worsens tau disease through a trafficking complex. Frontotemporal dementia strikes thinking early, and the CHCHD10 V57E variant emerged from patients, yet its effect on tau driven disease was unknown. Fly and cell models carrying human tau were built.

The mutation worsened eye damage and climbing defects, and cut lifespan in flies carrying tau. In lab cells it damaged synapse health, raised output of total and modified tau, and lifted toxicity. Modified tau piled up inside the cell's endosomal recycling system. Draining a trafficking protein called Rab7A partly undid the harm. Deeper work showed the normal protein complex holds Rab7A idle, while the mutant breaks the complex and frees Rab7A to act.
