title: Cellular cytotoxicity against canine endothelial cells. Analysis of determinants recognized by CTL.
abstract: A method is described which permits culture of both arterial and venous canine endothelial cells. Cell-mediated cytotoxicity against cultured endothelial cells has been studied. A 51Cr-release assay was used to detect CTL generated in MLC. Both arterial and venous endothelial cells are lysed by CTL specifically. Cold target inhibition experiments have been performed to analyse the CTL-recognized antigens on arterial and venous endothelial cells. Different antigens are recognized by CTL on venous endothelial cells and PHA-blasts; it is possible that CTL recognize venous endothelial cells through class II antigens or E-M antigens. Arterial endothelial cells and PHA-blasts share CTL-recognized antigens.
