WebFeb 28, 2024 · A neuron at rest is negatively charged: the inside of a cell is approximately 70 millivolts more negative than the outside (−70 mV, note that this number varies by neuron type and by species). This voltage is called the resting membrane potential; it is caused by differences in the concentrations of ions inside and outside the cell. WebFeb 1, 2024 · REST is engulfed in autophagosomes, together with misfolded proteins, such as Aβ and tau, which, in turn, reduces REST abundance in the nucleus. Loss of REST in the nucleus causes an increase in expression of genes involved in neuronal death and AD pathology. REST-dependent epigenetic remodeling
