SST and Alzheimer disease: Recent experimental evidence revealed that SST and PV interneurons disintegrate structurally and functionally in mouse models of AD (Palop et al. 2007; Schmid et al. 2016; Chen et al. 2018; Verret et al. 2012; Martinez-Losa et al. 2018; Iaccarino et al. 2016), suggesting that dysfunctions of SST and PV interneurons may underlie impairments of theta and gamma oscillations observed in AD.
