The anticonvulsant and mood-stabilizing drug valproic acid attracts C. elegans and activates chemosensory neurons via a cGMP signaling pathway

Lucero E. Rogel-Hernandez, Helena Casademunt, Aravinthan D. T. Samuel, Miriam B. Goodman

This study shows valproic acid attracts C. elegans and activates chemosensory neurons via a cGMP signaling pathway involving tax-4, rGCs, and GPCRs.
