Nav1.1 currents on Qube

The sodium channel NaV1.1, highly expressed in fast spiking interneurons (FSIs), initiates the interneuron’s action potentials and promotes γ-oscillations, which are important for memory encoding and other cognitive functions. An impaired function of FSIs is associated with disorders like autism, schizophrenia, Alzheimer’s and others. Potentiators of NaV1.1 can restore γ-oscillations by recovering reduced FSI function and they have been shown to minimize cognitive dysfunction in transgenic mice with decreased levels of NaV1.1 in parvalbumin-positive neurons.
