How can you discover and define astrocyte sub-types and sub-states?

Astrocytes are among the most abundant cells in the mammalian central nervous system (CNS). They are integral to brain and spinal-cord physiology and perform many functions important for normal neuronal development, synapse formation, and proper propagation of action potentials. We still know very little, however, about how these functions change in response to immune attack, chronic neurodegenerative disease, or acute trauma.

Our work focuses on the mechanisms that induce different forms of reactive astrocytes, and how these reactive cells interact with other cells in the CNS in a positive or negative way.

We aim to apply this knowledge to reactive astrocytes in human disease, and believe that the discovery of astrocytes with different reactive states has important implications for the development of new therapies for CNS injury and diseases.
