A growing body of evidence indicates that natural killer (NK) cells are paramount to the identification and elimination of cancerous and pre-cancerous cells during normal immunosurveillance. In addition, NK cells provide a vital link between the innate and adaptive immune systems during an anti-tumoral response. In the present study, a novel fusion protein was designed from the extracellular portion of mouse UL16-binding protein-like transcript 1 (MULT1), a ligand for the activating NKG2D receptor on NK cells, and a short arginine-glycine-aspartic acid (RGD) -containing peptide, which binds the integrin αvβ3 of tumor-specific neovasculature. In vitro studies showed that the fusion protein …

One of the strategies that tumor cells adopt to evade immunosurveillance mounted by elements of the innate immune system, such as NK cells, is to down-regulate certain cell surface molecules through a process also called shedding. Mouse UL16-binding protein-like transcript 1 (MULT1), which can activate NK cells through NK cell receptor NKG2D, is one of such molecules. Tumor cells can also avoid Fas mediated apoptosis by down-regulating its expression, secreting antagonistic `decoy' receptors, or expressing anti-apoptotic molecules. In this study, we report the design and evaluation of the antitumor activity of a novel fusion protein MULT1E/FasTI, consisting of the extracellular …
