Fic determinants for efficacy are of high priority. Although the exact host immune response to PVSRIPO oncolysis in patients remains unclear, we hypothesize that the multiplex direct viral effects on the host cell and the host innate anti-viral defense conspire to engage effector antitumor immune responses directed against the target tumor. Of particular interest in this context is recent insight that implicate PV-related enteroviruses, their cytotoxic effects on Curr Opin Virol. Author manuscript; available in PMC 2016 August 01. Brown and Gromeier Page 5 pancreatic insulin-producing beta cells, and their relation to Mda5 and the innate anti-viral interferon response, in the pathogenesis of type 1 diabetes. In this scenario, a convergence of targeted enteroviral cytotoxicity and Mda5 engagement result in recruiting cytotoxic T cell responses against beta cell antigens. The immunogenic potential implicit in such enterovirus-induced autoimmune pathogenesis is evident as the power to breach self-tolerance, a MG516 manufacturer property most desirable for overcoming the notorious suppression of immune effector responses inherent to cancer. Author Manuscript Author Manuscript Author Manuscript Author Manuscript Conclusions Our approach of using an attenuated PV recombinant for the treatment of cancer was founded on the exquisite Zotarolimus manufacturer specificity of the virus for malignancy, both tumor cells and stromal APCs. This begins at the earliest stage with the virus’ relation to its receptor, continues with factors that govern IRES competence in cancerous cells and engage the cytosolic pattern recognition receptor MDA5. Perhaps the most exciting answers on how PVSRIPO efficacy is achieved will come from future studies focused on identifying the role of the host immune system’s response to loco-regional virus tumor cell killing and inflammation. Defining such roles is of utmost importance, because it will guide future efforts to optimize OV therapy in the clinic and extend the clinical spectrum of indications suitable to intervention with PVSRIPO. Recent reports indicate that humans may be either hyposensitive or hypersensitive to the behavioral detections of dietary fat in the oral cavity and that obese humans may have a reduced fat taste sensitivity. Furthermore using analogous animal models, we have shown that PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/19854301 obesity-prone and obesity-resistant strains of rat exhibit differential sensitivity to fatty acid detection following a conditioned taste aversion. Obesity-prone rats appear more behaviorally sensitive to fatty acids showing stronger conditioned taste aversions with slower extinction rates for linoleate than obesity-resistant rats and OM rats show stronger behavioral preferences for linoleic acid than S5B/Pl rats. Fatty acids are transduced by multiple receptors on the tongue such as CD36, a host of G protein-coupled receptor -mediated pathways and delayed rectifying potassium channels. While there does not appear to be differential expression of CD36, GPR40, GPR120 between the OM and S5B/Pl strains, there is differential expression of fatty acid-sensitive and fatty acid-insensitive DRK channels between the two strains such that S5B/Pl rats have a greater ratio of fatty acid-sensitive to insensitive DRK channels than OM rats . This differential expression of fatty acid-sensitive DRK channels is predicted to lead to greater taste receptor cell activation by fatty acids in the S5B/Pl strain compared to the OM strain.
