Sleeve gastrectomy improves metabolic health, cognition, and Alzheimer's Disease pathology in 3xTG mice

Reji Babygirija, Julia A. Illiano, Michelle M. Sonsalla, Grace Zhu, Twinkle Mathew, Tristan Molkentin, Meredith Peterson, Carolyn Winder, Fan Xiao, Justin M. Wolter, Dudley W. Lamming, David A. Harris

This study shows that sleeve gastrectomy improves metabolic health, cognition, and Alzheimer's pathology in 3xTg-AD mice by modulating autophagy and insulin signaling.

A low protein diet drives short- and long-term improvements in metabolic health in a mouse model of sleeve gastrectomy

Julia A. Illiano, Cara L. Green, Alina Chao, Grace Zhu, Luiz Lopez, Odin Schaepkens, Cholsoon Jang, Dudley W. Lamming, David A. Harris

This study shows that a low protein diet enhances metabolic health and weight loss in mice after sleeve gastrectomy, challenging current high-protein dietary recommendations.
