Ptotic viruses market Ag cross-presentation (Livingston-Rosanoff and Mocarski, in preparation), leading to a model that relates Ag load and CD8 T cell response (Fig. 3). The current success of rhesus macaque CMV as a model SIV vaccine vector (119, 125) might undoubtedly stem from predicted proapoptotic nature of this vector due to the disruption of vICA activity (71). It will be of interest to identify whether or not matched pro-apoptotic or pro-necrotic rhesus macaque CMV mutants show enhanced cross-presentation properties comparable to murine CMV mutants in mice.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptConclusionThe capacity in the host to switch-hit in between apoptosis and necrosis pathways really likely facilitates innate clearance of a lot of intracellular pathogens, regardless of the fact that adenoviruses, poxviruses and herpesviruses all encode potent cell death suppressors which have limited the influence of cell death in host defense (three, 14, 15, 25, 26, 37, 68). The balanceJ Immunol. Author manuscript; accessible in PMC 2015 March 01.Mocarski et al.Pageof cell death contributes to inflammation, cross-presentation and manage of viral infection as well as life-long adaptive immune memory that prevents reinfection. Cell death pathways that evolved to help host defense are totally dispensable for improvement. It really is eye-catching to think about how these pathways can be harnessed to enhance innate host resistance to infection and increase immunogenicity of vaccines.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptAcknowledgmentsWe thank colleagues in the Emory Vaccine Center for the environment exactly where the ideas presented here have been developed and discussed.Literature Cited1.
