Fig. 5From: Nanoparticle-based delivery systems modulate the tumor microenvironment in pancreatic cancer for enhanced therapyCilengitide encapsulated in a doxorubicin (DOX)-loaded thermosensitive liposome via a MT1-MMP-cleavable peptide improves tumor blood perfusion and drug delivery in pancreatic cancer. Cilengitide is released through MT1-MMP cleavage on tumor endothelial cells (ECs), promoting EC migration and angiogenesis. MT1-MMP, membrane type 1-matrix metalloproteinase; MC, MT1-MMP-activated cilengitide. Reprinted by permission from [79]Back to article page
