Study teases out how ‘good bacteria’ keep us metabolically fit. The innate immune system, our first line of defense against bacterial infection, has a side job that’s equally important: fine-tuning our metabolism. The study, led by Paula Watnick, MD, PhD, of the Division of Infectious Diseases at Boston Children’s Hospital, reveals that innate immune pathways, best known as our first line of defense against bacterial infection, have a side job that’s equally important.

In the intestine, digestive cells use an innate immune pathway to respond to harmful bacteria...
