Drug replicated recovery of the movement control produced by rehab in mice

A new study by UCLA Health researchers and colleagues has discovered what researchers say is the first drug to fully reproduce the effects of physical stroke rehabilitation in model mice, following from human studies. The findings, published March 15, 2025 in Nature Communications, tested two candidate drugs derived from their studies on the mechanism of the brain effects of rehabilitation, of which one resulted in significant recovery in movement control after stroke in the mouse model. Stroke is the leading cause of adult disability because most patients do not fully recover from the effects of stroke. There are no drugs in the field of stroke recovery, requiring stroke patients to undergo physical rehabilitation which has shown to be only modestly effective. The open-access article is titled “Parvalbumin Interneurons Regulate Rehabilitation-Induced Functional Recovery After Stroke and Identify a Rehabilitation Drug.”
