L-Selectin Shedding Regulates Leukocyte Recruitment
The physiologic role of L-selectin shedding is unknown. Here, we investigate the effect of L-selectin shedding on firm adhesion and transmigration. In a tumor necrosis factor alpha-induced model of inflammation, inhibition of L-selectin shedding significantly increased firm adhesion and transmigration by a lymphocyte function-associated antigen (LFA)-1 and intercellular adhesion molecule (ICAM)...
متن کاملSelectin-independent leukocyte rolling and adhesion in mice deficient in E-, P-, and L-selectin and ICAM-1.
To study selectin-independent leukocyte recruitment and the role of intercellular adhesion molecule-1 (ICAM-1), we generated mice lacking all three selectins and ICAM-1 (E/P/L/I-/-) by bone marrow transplantation. These mice were viable and appeared healthy under vivarium conditions, although they showed a 97% reduction in leukocyte rolling, a 63% reduction in leukocyte firm adhesion, and a 99%...
متن کاملL-selectin–mediated Leukocyte Adhesion In Vivo: Microvillous Distribution Determines Tethering Efficiency, But Not Rolling Velocity
Adhesion receptors that are known to initiate contact (tethering) between blood-borne leukocytes and their endothelial counterreceptors are frequently concentrated on the microvilli of leukocytes. Other adhesion molecules are displayed either randomly or preferentially on the planar cell body. To determine whether ultrastructural distribution plays a role during tethering in vivo, we used pre-B...
متن کاملLeukocyte adhesion in capillary-sized, P-selectin-coated micropipettes.
OBJECTIVE Leukocyte retention in lung capillaries is observed in normal physiology and following a bacterial infection. It has been hypothesized that cells either become mechanically trapped or adhere to capillary endothelial cells via adhesion molecules. We propose that retention involves both mechanical and adhesive forces and that the biochemical adhesive force is modulated by mechanical for...
متن کاملLectin-like cell adhesion molecule 1 mediates leukocyte rolling in mesenteric venules in vivo.
During the inflammatory response, granulocytes and other leukocytes adhere to and emigrate from small venules. Before firm attachment, leukocytes are observed rolling slowly along the endothelium in venules of most tissues accessible to intravital microscopy. The molecular mechanism underlying this early type of leukocyte-endothelial interaction is unknown. Leukocyte rolling was investigated in...
