How mitochondrial and immune signals drive inflammation linked to Alzheimer's
NF-kappaB and Mitochondrial Signals as Positive and Negative Regulators of Inflammation
This project looks at how damaged mitochondria and immune signaling cause inflammation that may contribute to Alzheimer's disease.

What this research studies
Researchers are studying how signals inside immune cells and mitochondria trigger inflammation that could harm the brain in Alzheimer's. They focus on how newly made mitochondrial DNA gets oxidized, cut into fragments, and leaks out to activate the NLRP3 inflammatory sensor, and they examine enzymes and channels involved such as CMPK2, Fen1, VDAC, and OGG1. The team uses lab-grown cells and animal models and connects those findings to Alzheimer's risk factors like APOE ε4. Their goal is to find the molecular steps that could be targeted to reduce harmful brain inflammation.
Who could benefit from this research
Good fit: People with Alzheimer's disease or those at higher genetic risk (for example, APOE ε4 carriers) who are willing to provide blood or other biospecimens or to participate in related clinical protocols would be most relevant.
Not a fit: People without Alzheimer's, those not willing to provide samples, or those unable to access the La Jolla research site are unlikely to receive direct benefit from this work.
Why it matters
Potential benefit: If successful, this work could point to new ways to reduce brain inflammation and slow or prevent Alzheimer's progression.
How similar studies have performed: Prior laboratory and animal studies have linked NLRP3 and mitochondrial DNA to inflammation, but translating these findings into proven Alzheimer's therapies in people remains largely unproven.
