Astrocytes play key roles in sex-specific changes in brain and behaviour caused by early-life stress
In this study, Lewis Depaauw-Holt, working in the laboratory of Dr. Ciaran Murphy-Royal at Université de Montréal, investigated how early life stress influences brain and behaviour. They specifically aimed to elucidate the role of a non-neuronal brain cell, the astrocyte. The researchers showed striking differences in the response of males and females to early-life stress, differences that they could replicate in non-stressed mice by manipulating astrocytes chemically and genetically. These results suggest a perspective shift in our models of stress by directly implicating astrocytes in the behavioural, cellular, and synaptic response to stress.
