title: From leukocyte recruitment to resolution of inflammation: the cardinal role of integrins.
abstract: Integrins constitute a large group of adhesion receptors that are formed as heterodimers of α and β subunits. Their presence and activation status on the surface of leukocytes modulate a broad spectrum of processes in inflammation and immunity. This mini review critically outlines research advances with regard to the function of leukocyte integrins in regulating and integrating the onset and resolution of acute inflammation. Specifically, we summarize and discuss relevant, current literature that supports the multifunctional role of integrins and their partners. The latter include molecules that physically associate with integrins or regulate their activity in the context of the following: 1) leukocyte recruitment to an inflamed tissue, 2) recognition and phagocytosis of apoptotic neutrophils (efferocytosis), and 3) egress of efferocytic macrophages from the inflamed site to lymphoid tissues. The understanding of the fine-tuning mechanisms of the aforementioned processes by integrins and their functional partners may enable the design of therapeutic tools to counteract destructive inflammation and promote more efficient resolution of inflammation.
