Epigenetic perturbation unravels diverse origins, state conversions and de-differentiation of cortical astrocytes
DOT1L is established as a barrier between these astrocyte states, limiting differentiation of the astrocytes expressing phagocytosis marker genes, and lowering the DOT1L-mediated epigenetic barrier strongly favours appearance of astrocytes with limited phagocytosis properties and reactivation of progenitor programs.
