Microangiectasias: structural regulators of lymphocyte transmigration.
The migration of lymphocytes into inflammatory tissue requires the migrating cell to overcome mechanical forces produced by blood flow. A generally accepted hypothesis is that these forces are overcome by a multistep sequence of adhesive interactions between lymphocytes and endothelial cells. This hypothesis has been recently challenged by results demonstrating wall shear stress on the order of...
متن کاملGranzyme B promotes cytotoxic lymphocyte transmigration via basement membrane remodeling.
Granzyme B (GzmB) is a protease with a well-characterized intracellular role in targeted destruction of compromised cells by cytotoxic lymphocytes. However, GzmB also cleaves extracellular matrix components, suggesting that it influences the interplay between cytotoxic lymphocytes and their environment. Here, we show that GzmB-null effector T cells and natural killer (NK) cells exhibited a cell...
متن کاملCLEVER-1 mediates lymphocyte transmigration through vascular and lymphatic endothelium.
Common lymphatic endothelial and vascular endothelial receptor-1 (CLEVER-1; also known as stabilin-1 or FEEL-1) is a large multifunctional glycoprotein implicated in scavenging, angiogenesis, and cell adhesion. Here we studied the function of human CLEVER-1 in leukocyte trafficking. Lymphatic vessels expressed CLEVER-1 constitutively in skin in vivo, whereas on vascular endothelium it appeared ...
متن کاملULBPs: regulators of human lymphocyte stress recognition
NKG2D is a critical activatory molecule expressed on cytotoxic cells such as NK cells, γδ T cells and subsets of αβ T cells [1]. Ligation of NKG2D acts to trigger cytotoxicity of NK cells and acts as a co-stimulatory molecule on T cells. The ligands that bind to NKG2D, known as NKG2DL, are grouped into two families and comprise eight different proteins termed MIC-A/B and ULBP1-6 (Figure 1a). Im...
