"EXCITED ABOUT INHIBITION & MOVED BY MIGRATION"


Our brain is an intriguing organ that gradually becomes more active and refined during its development.
It is not surprising that disruption of brain development through genetic and environmental factors leads to neurodevelopmental diseases such as autism spectrum disorder and schizophrenia.

Since proper neurodevelopment is driven by the complex interplay between neurons and microglia, we focus on the impact of genetic and environmental factors on these cells. A genetic risk factor for autism spectrum disorder, directly acting at neuronal networks, is the impaired glycine receptor signaling in the brain.

Environmental factors impact the highly dynamic immune cells of the brain: microglia. Using molecular, cellular and behavioral approaches, we aim to understand the normal and pathological brain development in order to identify new targets with therapeutic potential  for neurodevelopmental disorders.
