Mesolimbic dopamine signaling mediates increased hedonic feeding and food seeking in lactating mice

Tanya Pattnaik, Benjamin Wang, Emma Borrowman, Vraj Patel, Qingying Zheng, Lara Villano, Patrick R. Sweeney

This study shows lactation increases food seeking and palatable food intake in mice through enhanced mesolimbic dopamine signaling, specifically via VTA-NAc dopamine transmission.

Elevated activity of the mesolimbic dopamine system promotes feeding during pregnancy in mice

Tanya Pattnaik, Benjamin Wang, Patrick R. Sweeney

This study identifies increased mesolimbic dopamine system activity as a driver of hedonic feeding and sensitivity to energy imbalance during pregnancy in mice.

Reduced melanocortin tone mediates increased feeding during pregnancy in mice

Ingrid Camila Possa‐Paranhos, Kerem Catalbas, Samuel Congdon, Tanya Pattnaik, Christina Nelson, Dajin Cho, Patrick R. Sweeney

This study identifies that increased AgRP neuron activity and decreased POMC neuron activity during pregnancy in mice drive hyperphagia, with spatial transcriptomics revealing transcriptional changes in these neurons.
