Non-classical monocyte homing to the gut via α4β7 integrin mediates macrophage-dependent intestinal wound healing

Abstract

In addition to reported effects on lymphocytes, anti-α4β7 therapy in IBD also targets non-classical monocytes. Impaired gut homing of such monocytes might lead to a reduction of wound healing macrophages and could potentially explain increased rates of postoperative complications in vedolizumab-treated patients, which have been observed in some studies.
