Transendothelial migration of human basophils.
During allergic reactions, basophils migrate from the blood compartment to inflammatory sites, where they act as effector cells in concert with eosinophils. Because transendothelial migration (TEM) represents an essential step for extravasation of cells, for the first time we have studied basophil TEM using HUVEC. Treatment of HUVEC with IL-1beta significantly enhanced basophil TEM, which was f...
متن کاملTransendothelial migration of 27E10+ human monocytes.
The myeloid-related proteins MRP8 (S100A8) and MRP14 (S100A9), two members of the S100 family of calcium-binding proteins, are co-expressed and form a cell-surface and cytoskeleton-associated heterodimer upon calcium mobilization which is recognized by the mAb 27E10. The heterodimer is abundantly expressed in the cytoplasm of granulocytes and a subpopulation of blood monocytes. Previously, we a...
متن کاملHuman neutrophils facilitate tumor cell transendothelial migration.
Tumor cell extravasation plays a key role in tumor metastasis. However, the precise mechanisms by which tumor cells migrate through normal vascular endothelium remain unclear. In this study, using an in vitro transendothelial migration model, we show that human polymorphonuclear neutrophils (PMN) assist the human breast tumor cell line MDA-MB-231 to cross the endothelial barrier. We found that ...
متن کاملPhenotypic characteristics of human monocytes undergoing transendothelial migration
In our study we characterised the immunophenotype of monocytes that migrated through an endothelial cell (EC) monolayer in vitro. We found that monocyte migration led to an enhanced expression of CD11a, CD33, CD45RO, CD54 [intercellular cell-adhesion molecule (ICAM)-1] and human leucocyte antigen-DR. The most striking increase was observed for ICAM-1 when ECs were activated with tumour necrosis...
متن کاملSignaling in leukocyte transendothelial migration.
Under a variety of (patho) physiological conditions, leukocytes will leave the bloodstream by crossing the endothelial monolayer that lines the vessels and migrate into the underlying tissues. It is now clear that the process of extravasation involves a range of adhesion molecules on both leukocytes and endothelial cells, as well as extensive intracellular signaling that drives adhesion and che...
