Vascular endothelial growth factors VEGF-A and VEGF-C are the main angiogenic factors that control growth of new blood and lymphatic vessels in the organism, and they also possess several immunoregulatory activities. Expression of VEGF-A and VEGF-C mRNA as well as mRNA for VEGF receptors in lymphocytes and macrophages of naive mice was investigated. Using(More)
Tumors spontaneously develop central necroses due to inadequate blood supply. Recent data indicate that dead cells and their products are immunogenic to the host. We hypothesized that macrophage tumor-dependent reactions can be mediated differentially by factors released from live or dead tumor cells. In this study, functional activity of resident(More)
Vascular endothelial growth factor is not only angiogenic, but also immunoregulatory factor. For evaluation of the possibility of its direct interaction with mouse thymocytes we studied the effect of vascular endothelial growth factor on proliferation and apoptosis of thymocytes and expression of genes for the corresponding receptor on these cells. Vascular(More)
In our study, we for the first time investigated a role for VEGF as a factor regulating transendothelial migration of murine thymocytes in vitro. Effects of VEGF were examined in a model of thymocyte migration across a monolayer of EA.hy 926 endothelial cells. We showed that VEGF enhanced transendothelial migration of murine thymocytes and their adhesion to(More)
