Overview

Reveals how alcohol affects excitatory signaling in the brain through corticotropin-releasing factor pathways, indicating new treatment targets.

Key Points

  • This research investigates how corticotropin-releasing factor (CRF) influences cholinergic interneurons (CINs) in the dorsal striatum and how alcohol alters this interaction.
  • Utilized both mice and rats for the experiment
  • Conducted monosynaptic and retrograde circuit tracing
  • Identified CRF-expressing neurons in the central amygdala and bed nucleus of the stria terminalis
  • Performed functional recordings of CIN excitability and acetylcholine release
  • Confirmed that CINs express CRF receptor 1 (CRFR1) and are connected to CRF + projections
  • Found that CRF enhances CIN excitability and increases acetylcholine release
  • Observed that acute alcohol exposure and withdrawal significantly reduce CRF's excitatory effects on CIN firing
