Gut microbes' partnership helps body extract energy from food, store it as fat

...m affect each other and their hosts. Gordon's lab models the interactions between friendly gut microbes and their hosts using gnotobiotic mice. These mice are raised in a manner that keeps them germ-free. They are then colonized with one or more human gut-derived microbes to study how microbial-microbial a...

... study. "By analyzing genetically engineered mouse models with reduced c-myc, reduced IL-15 or absent IL-15, we discovered that it's actually c-myc, which is known primarily as an oncogene, that acts downstream of the IL-15 signaling pathway to regulate T memory cell homeostasis." According to Dr. MacDonald...

Less agitation in AD patients, less stress and depression in caregivers with collaborative care
