Evaluation of the influence of recombinant human tumor necrosis factor on adhesive ability of human fetal umbilical vein endothelial cells to К562 and L1210 cells
Regulation of adhesion receptors (AR) expression on endothelial cells (EC) is controlled by tumor necrosis factor (TNF), a pleiotropic cytokine, being a local mediator of cellular homeostasis and immune response. TNF is one of the first cytokines that are secreted in inflammation and lymphoid tumors...
