Abstract
Adhesion and transmigration of leukocytes into arterial walls occurs after vascular injury and may play a role in the development of atherosclerosis and restenosis. This protocol presents a simple, rapid method for quantifying leukocyte adhesion to artery segments ex vivo. The procedure involves isolating leukocytes from rabbit whole blood and labelling with the gamma-emitting isotope 51Cr. Labelled leukocytes are added to open rings of subclavian artery taken from the same rabbit. After gamma counting, percentage leukocyte adhesion can be calculated with reference to a sample containing a quantity of labelled leukocytes equivalent to that which was added to the artery. Leukocyte adhesion was increased by l-NAME, thrombin and increasing incubation time and decreased by low temperatures. In addition, leukocyte adhesion was found to be increased following a vascular stretch injury performed in vitro. This protocol offers a number of advantages: the rapidity of the leukocyte isolation and labelling; the small quantity of leukocytes required; the ability to use autologous leukocytes; the applicability to whole arteries and arteries injured in vitro or in vivo, allowing the effects of vascular injury on leukocyte adhesion to be studied.
