Platelets Guide Leukocytes to Their Sites of Extravasation
Effective immune responses require the directed migration of leukocytes from the vasculature to the site of injury or infection. How immune cells "find" their site of extravasation remains largely obscure. Here, we identified a previously unrecognized role of platelets as pathfinders guiding leukocytes to their exit points in the microvasculature: upon onset of inflammation, circulating platele...
متن کاملPlatelets mediate oxidized low-density lipoprotein-induced monocyte extravasation and foam cell formation.
OBJECTIVE A growing body of evidence indicates that platelets contribute to the onset and progression of atherosclerosis by modulating immune responses. We aimed to elucidate the effects of oxidized low-density lipoprotein (OxLDL) on platelet-monocyte interactions and the consequences of these interactions on platelet phagocytosis, chemokine release, monocyte extravasation, and foam cell format...
متن کاملExtravasation Injuries in Adults
Insertion of an intravascular catheter is one of the most common invasive procedures in hospitals worldwide. These intravascular lines are crucial in resuscitation, allow vital medication to be administered, and can be used to monitor the patients' real-time vital parameters. There is, however, growing recognition of potential risks to life and limb associated with their use. Medical literature...
متن کاملExtravasation injuries.
OBJECTIVES To evaluate the time and type of treatment following extravasation from intravenous infusion and the sequelae of the injuries. METHOD The charts of 12 patients who were referred to the Plastic and Orthopaedic Services at the University Hospital of the West Indies were reviewed. The study period was between May 2003 and January 2007. Data were collected on age, gender, site of extra...
متن کاملCirculating activated platelets assist THP-1 monocytoid/endothelial cell interaction under shear stress.
Circulating complexes of leukocytes and activated platelets are markers for atherosclerosis, but their interaction with the arterial endothelial lining has not been studied. Therefore, the effect of activated platelets on rolling and adhesion of labeled human THP-1 monocytoid cells to human umbilical vein endothelial cell (HUVEC) monolayers was studied by epifluorescence microscopy in a paralle...
