A Mouse Brain Reset Within Hours, Then the Effect Faded
Rapamycin temporarily reversed several adult brain and behavior changes linked to maternal inflammation in a mouse model.
Summary
Rapamycin temporarily reversed several adult brain and behavior changes linked to maternal inflammation in a mouse model.
A UCLA-led mouse study linked maternal immune activation during pregnancy to lasting network overactivity, sensory sensitivity, repetitive behavior, and seizure vulnerability in adult offspring. One rapamycin dose rapidly improved several measured changes, but the benefit was temporary and repeated dosing lost efficacy. The model identifies a signaling pathway for research; it is not evidence that rapamycin treats autism in people.
Why it matters
