New publication!! Sara Clasen’s paper on how commensal gut bacteria evade the immune system is published in Science Immunology

Here, we address this long-standing question in microbiome sciences.

Here, we address the long-standing question of how benign gut microbes evade the immune system. We identified a new type of flagellin in the human gut, termed ‘silent flagellin,’ that binds to the immune receptor Toll-like receptor 5 without inducing a pro-inflammatory response. The findings provide a mechanism for the immune system to tolerate beneficial microbes while remaining responsive to pathogens.
