Introduction And Objective: The role of secreted gut microbial components in the initiation of systemic inflammation and consequences of antibiotic therapies on this inflammatory process are poorly elucidated. We investigate whether peripheral innate cells mount an inflammatory response to gut microbial components, the immune cells that are the primary drivers of systemic inflammation, the bacterial populations that are predominantly responsible, and whether perioperative antibiotics affect these processes.
Method And Experimental Design: Conditioned supernatants from gut microbes were used to stimulate murine innate cell types in vitro and in vivo, and proinflammatory responses were characterised.
