Chemogenetic Therapy Restores Axon Segment, Boosts Mouse Social Skills

6/30/2026

Summary

Story summary

Chemogenetic therapy re-elongated the axon initial segment in autism-model mice, improving social behavior.
The experiment involved 214 mice; 11 per group displayed normalized social interaction and fewer buried marbles after treatment.
Patch-clamp data showed a shortened segment in medial prefrontal cortex neurons projecting to the dorsal raphe, reducing excitability.
Authors acknowledge using fixed tissue, a single mouse model, and the need for live-cell and human studies.
