• Note (General): type:Thesis; Recent basic and clinical studies have shown that the programmed death ligand (PD-L)/PD-1 pathway has a significant role in tumour immunity, and its blockade has a therapeutic potential against several human cancers. We hypothesized that anti-angiogeneic treatment might augment the efficacy of PD-1 blockade. To this end, we evaluated combining the blockade of PD-1 and vascular endothelial growth factor receptor 2 (VEGFR2) in a murine cancer model using Colon-26 adenocarcinoma. Interestingly, simultaneous treatment with anti-PD-1 and anti-VEGFR2 monoclonal antibodies (mAbs) inhibited tumour growth synergistically in vivo without overt toxicity. Blocking VEGFR2 inhibited tumour neovascularization significantly, as demonstrated by the reduced number of microvessels, while PD-1 blockade had no impact on tumour angiogenesis. PD-1 blockade might promote T cell infiltration into tumours and significantly enhanced local immune activation, as shown by the up-regulation of several proinflammatory cytokine expressions. Importantly, VEGFR2 blockade did not interfere with T cell infiltration and immunological activation induced by PD-1 blockade. In conclusion, simultaneous blockade of PD-1 and VEGFR2 induced a synergistic in-vivo anti-tumour effect, possibly through different mechanisms that might not be mutually exclusive. This unique therapeutic strategy may hold significant promise for future clinical application.; 博士（医学）・甲第600号・平成25年5月29日; © 2013 British Society for Immunology; This article has been accepted for publication in Clinical and experimental immunology Published by Oxford University Press.; identifier:Clinical and experimental immunology Vol.172 No.3 p.500-506 (2013 Jun); identifier:00099104; identifier:http://ginmu.naramed-u.ac.jp/dspace/handle/10564/2588; identifier:Clinical and experimental immunology, 172(3): 500-506
