In December a portion of the lab traveled to snowy Banff, Canada to attend the Keystone Symposia Meeting “The Human Microbe: Ecology and Evolution.” Ruth presented a talk on the lab’s recent findings on silent recognition of human gut bacterial flagellins by toll-like receptor 5 (now published here!). Taichi Suzuki presented a talk titled “Codiversification of Gut Microbiota with Humans” (paper available here) and other lab members shared their latest research in the poster sessions. Despite exceptionally frigid weather, winter fun was had on skis and fat tire bikes during breaks from the networking and exciting science.
