During angiogenesis, vascular endothelial growth factor and basic fibroblast growth factor regulate natural killer cell adhesion to tumor endothelium

R J Melder et al. Nat Med. 1996 Sep.

Abstract

Localization of activated natural killer (A-NK) cells in the microvasculature of growing tumors is the result of recognition of the intracellular and vascular cell-adhesion molecules ICAM-1 and VCAM-1 on the tumor endothelium, mediated by lymphocyte function-associated protein LFA-1 and vascular lymphocyte function-associated protein VLA-4. In vitro and in vivo studies of A-NK cell adhesion to endothelial cells showed that vascular endothelial growth factor (VEGF) promotes adhesion, whereas basic fibroblast growth factor (bFGF) inhibits adhesion through the regulation of these molecules on tumor vasculature. Thus, some angiogenic factors may facilitate lymphocyte recognition of angiogenic vessels, whereas others may provide such vessels with a mechanism that protects them from cytotoxic lymphocytes.
