Parkinson's disease (PD), a movement disorder, is the second most common neurodegenerative disease after Alzheimer's disease (AD). Beyond age and genes, exposures such as pesticides, heavy metals, bacteria and viruses raise PD risk.

What they work on

  1. Determine how developmental exposure to environmental neurotoxins changes innate immune signaling in glial cells, altering the brain's inflammatory response to later toxic exposures during aging, using long-term studies in transgenic models.
  2. Identify key molecular pathways in glial cells, altered by exposure to environmental neurotoxicants such as pesticides and heavy metals, that regulate the brain's inflammatory response to viral infection.
  3. Map molecular signatures of glial activation states in different brain regions across disease progression triggered by toxicants and viruses, using single-cell and spatial transcriptomics, high-content imaging and neural network-based analysis.

More about the research

How these exposures add up over a lifetime to trigger disease is largely unknown. One early step appears to be inflammation driven by glial cells, the brain's support and immune cells.

Why it matters

Many people are exposed to pesticides, heavy metals and infections that raise risk for Parkinson's and Alzheimer's disease. Identifying the glial signaling pathways that convert these exposures into brain inflammation could reveal molecular targets for slowing disease before symptoms appear. It could also clarify which combinations of exposures matter most.
