My research focuses on stroke and infectious/inflammatory aggressions occurring in the developing brain and responsible for severe handicaps, ie cerebral palsy, learning disabilities and behaviourial disorders such as autism. Through a combination of clinical and experimental approaches, our team has shown that prenatal exposure to bacterial components induces cerebral lesions, through cytokines'release, and predisposes to circulatory defects which occur immediately after birth.
