A Drd1-cre mouse line with nucleus accumbens gene dysregulation exhibits blunted fentanyl seeking

Annalisa Montemarano, Logan D. Fox, Farrah A. Alkhaleel, Alexandria E. Ostman, Hajra Sohail, Samiksha Pandey, Laura B. Murdaugh, Megan E. Fox

This study investigates fentanyl relapse mechanisms using a Drd1-cre mouse line, finding blunted fentanyl seeking despite similar self-administration and increased D1 receptor expression.
