Early Alzheimer's effects on the brain system that shapes emotions and bodily feelings

An animal model of early Alzheimer’s disease pathogenesis in the interoceptive-allostatic network

NIH-funded research University of California at Davis · NIH-11297720

Using a monkey model, researchers introduce small Alzheimer-related proteins to learn how they harm the brain circuits that control emotions and internal bodily signals.

What this research studies

This work uses middle-aged rhesus monkeys and delivers toxic amyloid-beta oligomers believed to appear early in Alzheimer’s disease. The team tracks changes in thinking and emotional behavior while measuring synapse loss, neuroinflammation, and protein buildup in brain regions that generate feelings and regulate the body's internal state. The focus is on the interoceptive-allostatic network, a set of brain hubs that shape affect and bodily awareness. Results aim to mirror the earliest steps of human Alzheimer’s pathogenesis to inform future human-focused studies.

Who could benefit from this research

Good fit: Ideal candidates for follow-up human work would be people with very early Alzheimer's disease or mild cognitive impairment who are willing to share symptom information or biological samples.

Not a fit: People without Alzheimer's or those with late-stage disease are unlikely to receive direct benefit from this animal-based project in the near term.

Why it matters

Potential benefit: If successful, the project could reveal early brain changes that explain emotional and bodily symptoms in Alzheimer's and point to targets for earlier diagnosis or new therapies.

How similar studies have performed: Previous preclinical work, including studies in nonhuman primates, has shown that amyloid-beta oligomers can damage synapses and trigger inflammation, but translating these findings into effective human treatments is still unproven.
