摘要

Recent evidence demonstrates that dendritic cells (DCs) can insert dendrites between the epithelial cells that form the barrier protecting the body from the gut contents. Although first observed almost a decade ago, this is a controversial area of DC biology and the physiological importance of this phenomenon is only now being clarified. A recent study by Niess and colleagues shows that this behaviour enables efficient sampling of both invasive and non-invasive bacteria and might enhance the ability of an organism to resist infections by a pathogenic strain of Salmonella.
