Adolescent Nicotine Exposure Permanently Alters Brain Stress Peptides and Adult Anxiety
Rats exposed to nicotine during adolescence had persistently increased CRF and NPY immunoreactivity in stress/anxiety brain regions as adults, correlating with increased anxiety-like behavior — adolescent nicotine permanently rewires stress circuits.
Quick Facts
What This Study Found
Adolescent nicotine exposure produced lasting increases in CRF-like and NPY-like immunoreactivity in amygdala and hypothalamic stress regions in adult rats, correlating with increased anxiety — adolescent nicotine permanently alters brain stress peptide systems.
