Projection-defined ventral tegmental area neurons exhibit distinct molecular adaptations during acute fentanyl withdrawal

Annalisa Montemarano, Hajra Sohail, Meghan E. Hnilo, Logan D. Fox, Arial Briones, Alexandria E. Ostman, Megan E. Fox

The paper examines molecular adaptations in VTA neurons during fentanyl withdrawal, finding distinct transcriptional responses based on projection targets.

Mesolimbic and mesocortical pathways differentially support fentanyl-context associations

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

This study investigates how VTA-NAc and VTA-PFC circuits contribute to fentanyl-context associations and identifies distinct dopamine receptor roles in context-seeking behavior.

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.
