Anterior cingulate cortex parvalbumin and somatostatin interneurons shape social behavior in male mice.

ABSTRACT: The anterior cingulate cortex (ACC) is essential for social behavior, and its dysfunction is implicated in social interaction deficits in autism. Pyramidal neuron activity in the ACC is modulated by parvalbumin (PV) and somatostatin (SST) interneurons, though their specific roles in social interactions remain unclear. Here, we demonstrate that PV and SST interneurons differentially contribute to the regulation of social interactions. In a Shank3-deficient autistic model, the expression of Kcnh7, a risk gene for autism, is reduced in both PV and SST interneurons. Knocking out Kcnh7 in either interneuron subtype leads to social interaction deficits. Furthermore, projections from the lateral posterior thalamic nucleus (mediorostral part, LPMR) to PV interneurons and from the ventral hippocamp
