白细胞通常作为非贴壁细胞通过血流,但在免疫反应和炎症过程中,它们会变得贴壁,以便在组织中迁移。三个粘附分子家族,即免疫球蛋白家族、选择素和整联蛋白,参与白细胞和组织之间的相互作用。在炎症部位附近,白细胞最初通过选择素与内皮细胞相互作用,导致它们减慢速度并沿着血管壁滚动。接下来,趋化素诱导白细胞上整合素的激活。最后,激活的整合素介导白细胞通过内皮迁移到发炎部位。白细胞与其他细胞和各种细胞外基质 (ECM) 蛋白的相互作用导致不同的功能细胞反应,包括生长、行为和分化的变化。其中许多相互作用是由整合素介导的,整合素将 ECM 蛋白信号与细胞骨架“整合”,并且还充当在细胞内产生生化信号的真正受体。整合素结合后,pH、细胞质 Ca2+ 浓度、磷酸化和基因诱导均发生变化。单核细胞中粘附介导的基因诱导可能是整合素在细胞中启动信号级联以将信息从 ECM 一直传递到细胞核的最好例子。 J.洛科克。生物。 57:189–198:1995。
Leukocytes usually pass through the blood stream as nonadherent cells, but during an immune response and inflammation, they become adherent in order to migrate through tissues. Three families of adhesion molecules, the immunoglobulin family, the selectins, and the integrins, participate in interactions between leukocytes and tissues. Near sites of inflammation, leukocytes initially interact with the endothelium via selectins, causing them to slow down and to roll along the walls of blood vessels. Next, chemoattractans induce the activation of integrins on leukocytes. Finally, activated integrins mediate leukocyte migration through the endothelium into the inflamed site. Interactions of leukocytes with other cells and various extracellular matrix (ECM) proteins lead to different functional cell responses, including changes in growth, behavior, and differentiation. Many of these interactions are mediated by integrins, which “integrate” ECM protein signals with the cytoskeleton and which also act as true receptors that generate biochemical signals within the cell. Changes in pH, cytoplasmic Ca2+ concentration, phosphorylation, and gene induction have all been observed after integrin engagement. Adhesion‐mediated gene induction in monocytes is perhaps the best example that integrins initiate signaling cascades in the cell to deliver information from the ECM all the way to the nucleus. J.
