ECT Reprograms Adult Neurons into a Youthful State
Researchers have developed a stimulation protocol called REPOPS that mimics electroconvulsive therapy to induce cellular dematuration in adult neurons. This process causes mature neurons to revert to a more plastic, youthful state by activating specific cell-cycle proteins.
Why it matters
This discovery provides a potential biological mechanism for how brain stimulation therapies treat psychiatric conditions like depression and schizophrenia.
Summary: Researchers engineered a highly specialized patterned stimulation protocol called REPOPS (Repeated Electroconvulsive-like Patterned Optical/Electrical Stimulation) in murine models to precisely mirror the neural activation patterns of ECT. The empirical data unmasked a stunning structural transformation: intensive ECT-like stimulation coaxes fully mature, non-dividing adult neurons to undergo an active process of cellular dematuration .
By entering a state of nuclear reprogramming driven unexpectedly by the cell-cycle protein Cyclin B , mature neurons fundamentally reshape their identity, winding back their genetic clocks to resemble highly plastic, early postnatal developmental states.
Nearly 90 years after Ugo Cerletti and Lucio Bini introduced electroconvulsive therapy (ECT), brain stimulation therapies such as ECT and Repetitive Transcranial Magnetic Stimulation (rTMS) are common in psychiatry because they are highly effective for treating depression and schizophrenia, yet their cellular mechanisms remain poorly understood.
