Neuroimmunologist, Aleksandra Deczkowska investigates how the immune system and the microbiome shape the development, health, and disease of the nervous system. Her work suggests that one of the brain’s “barrier” tissues, the choroid plexus, is a site of lively communication between the microbiome, the immune system, and the brain. Her vision is to harness the unique properties of the choroid plexus to design new therapeutic approaches to neurological diseases.
