Microglial activation and inflammation linked to brain consequences after pathogen exposure

Official title: Microglial activation and inflammatory cytokine secretion as mechanisms driving CNS consequences of intermittent exposure to pathogens

Funded at Tulane University of Louisiana · NIH-11450710 · Data updated 2026-11-12

This research looks at how infection history and brain inflammation may contribute to dementia and other brain problems, with a focus on aging adults who may be at risk.

Who could benefit from this research

Could help

Adults 21 years and older, including individuals with or at risk for Alzheimer’s disease dementia, who have a history of infectious exposure.

Less likely to help

Individuals without significant infection exposure history or without risk factors for cognitive decline may see limited direct benefit.

What this research studies

This project examines how prior infections and the brain’s inflammatory response could influence the development of dementia. Using human and mouse models, it will study microglial activation, cytokine signals, and changes in brain energy metabolism and the blood-brain barrier. The team plans to integrate transcriptional and epigenetic analyses to understand long-term brain and behavior effects. The goal is to uncover mechanisms that could lead to prevention or early interventions for infection-related cognitive decline.

Why it matters

Potential benefit: If successful, findings could inform strategies to prevent or lessen dementia related to past infections by targeting brain inflammation.

How similar studies have gone: Preliminary data and existing literature suggest neuroinflammation post-infection can affect brain function, but causal pathways remain to be clarified.
