Influence of cell physiological state on gene delivery to T lymphocytes by chimeric adenovirus Ad5F35
Adoptive transfer of genetically-modified T cells is a promising approach for treatment of both human malignancies and viral infections. Due to its ability to efficiently infect lymphocytes, the chimeric adenovirus Ad5F35 is potentially useful as an immunotherapeutic for the genetic modification of T cells. In previous studies, it was found that the infection efficiency of Ad5F35 was significan...
متن کاملIdentification of Adenovirus Serotype 5 Hexon Regions
24 Most of an intravenous dose of species C adenovirus serotype 5 (Ad5) is 25 destroyed by liver Kupffer cells. In contrast, another species C virus, Ad6, evades these 26 cells to mediate more efficient liver gene delivery. Given that this difference in Kupffer 27 cell interaction is mediated by the hypervariable (HVR) loops of the virus hexon protein, 28 we genetically modified each of the sev...
متن کاملDevelopment of a targeted gene vector platform based on simian adenovirus serotype 24.
Efforts to develop adenovirus vectors suitable for genetic interventions in humans have identified three major limitations of the most frequently used vector prototype, human adenovirus serotype 5 (Ad5). These limitations--widespread preexisting anti-Ad5 immunity in humans, the high rate of transduction of normal nontarget tissues, and the lack of target-specific gene delivery--justify the expl...
متن کاملIntramuscular delivery of adenovirus serotype 5 vector expressing humanized protective antigen induces rapid protection against anthrax that may bypass intranasally originated preexisting adenovirus immunity.
Developing an effective anthrax vaccine that can induce a rapid and sustained immune response is a priority for the prevention of bioterrorism-associated anthrax infection. Here, we developed a recombinant replication-deficient adenovirus serotype 5-based vaccine expressing the humanized protective antigen (Ad5-PAopt). A single intramuscular injection of Ad5-PAopt resulted in rapid and robust h...
متن کاملNeutralizing antibodies and CD8+ T lymphocytes both contribute to immunity to adenovirus serotype 5 vaccine vectors.
The high prevalence of preexisting immunity to adenovirus serotype 5 (Ad5) in human populations will likely limit the immunogenicity and clinical utility of recombinant Ad5 vector-based vaccines for human immunodeficiency virus type 1 and other pathogens. Ad5-specific neutralizing antibodies (NAbs) are thought to contribute substantially to anti-Ad5 immunity, but the potential importance of Ad5...
