AbstractGLP-1 receptor agonists (GLP-1RAs) are effective anti-obesity drugs. However, the precise central mechanisms of GLP-1RAs remain elusive. We administered GLP-1RAs to obese patients and observed heightened sense of preingestive satiation. Analysis of human and mouse brain samples pinpointed GLP-1R neurons in the dorsomedial hypothalamus (DMH) as candidates for encoding preingestive satiation. Optogenetic manipulation of DMHGLP-1R neurons caused satiation.

AbstractOur bodies are inhabited by trillions of microorganisms. The host immune system constantly interacts with the microbiota in barrier organs, including the intestines. Over decades, numerous studies have shown that our mucosal immune system is dynamically shaped by a variety of microbiota-derived signals. Elucidating the mediators of these interactions is an important step for understanding how the microbiota is linked to mucosal immune homeostasis and gut-associated diseases.
