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 WebA single neuron, or nerve cell, can do a lot! It can maintain a resting potential —voltage across the membrane. It can fire nerve impulses, or action potentials. And it can carry out the metabolic processes required to stay alive.

WebAt rest, a typical neuron has a resting potential (potential across the membrane) of -60 −60 to -70 −70 millivolts.
