Summary

Adult offspring exposed to mild maternal inflammation showed sensory and behavioral abnormalities that largely eased after mTOR inhibition.

In a mouse model, mild immune activation during pregnancy produced adult offspring with brain-circuit overactivity, altered sensory responses, repetitive behavior and greater seizure susceptibility. Researchers report that a single rapamycin dose rapidly improved most of the measured abnormalities by dampening mTOR signaling. The animals are described as showing autism-like traits, but a mouse rescue experiment is not evidence that rapamycin treats autism in people.

Why it matters

Adult offspring exposed to mild maternal inflammation showed sensory and behavioral abnormalities that largely eased after mTOR inhibition.

Limits and context

  • The animals are described as showing autism-like traits, but a mouse rescue experiment is not evidence that rapamycin treats autism in people.

Key claims

  1. Adult offspring exposed to mild maternal inflammation showed sensory and behavioral abnormalities that largely eased after mTOR inhibition.

    Qualification: The animals are described as showing autism-like traits, but a mouse rescue experiment is not evidence that rapamycin treats autism in people.
