HSV-1’s impact on brain immune cells is examined in a research article, promising a clear look at how infection reshapes microglial behavior and molecular identity.
Key Takeaways
- HSV-1 infection drove microglia into interferon-dominated antiviral states with distinct transcriptional profiles.
- Chromatin accessibility changes after HSV-1 exposure silenced homeostatic and maintenance genes in microglia.
- The virus-induced microglial state closely resembled molecular signatures associated with aging and Alzheimer’s disease.
