Virus cell entry represents one of the earliest opportunities for a host to respond to infection. Understanding the processes of pathogen detection and restriction employed by the host, as well as strategies utilized by the virus itself to evade such processes, is critical in developing therapeutics to counter pathogenesis. Adenovirus (Ad) infections are self-limiting in healthy populations, but can be devastating to individuals with compromised immune systems. Currently, no specific antiviral treatments exist to combat Ad infections in susceptible populations. However, because Ad infections are not severe in healthy individuals, employing replication-defective Ads as vaccine vectors is generally regarded as …

Head-to-head comparisons of conventional influenza vaccines with ade- novirus (Ad) gene-based vaccines demonstrated that these viral vectors can mediate more potent protection against influenza virus infection in animal models. In most cases, Ad vaccines are engineered to be replication-defective (RD-Ad) vectors. In contrast, replication-competent Ad (RC-Ad) vaccines are markedly more potent but risk causing adenovirus diseases in vaccine recipients and health care workers. To harness antigen gene replication but avoid production of infectious virions, we de- veloped “single-cycle” adenovirus (SC-Ad) vectors. Previous work demonstrated that SC-Ads amplify transgene expression 100-fold and produce markedly stronger and more persistent immune responses than …
