Co-infection is common among viruses and bacteria in the human respiratory system. Adenovirus (AdV) and Streptococcus pneumoniae are clinically relevant respiratory pathogens that cause morbidity and mortality in a variety of patient populations with the highest morbidity occurring among immunocompromised individuals, but also prevalent in infants and the elderly. Acute respiratory distress syndrome may become severe in healthy individuals when co-infection with S. pneumoniae and AdV occurs due to synergistic effects of the pathogens on the host. I hypothesized that S. pneumoniae infection decreases AdV transduction of airway epithelia. To test this hypothesis, we utilized the polarized immortalized airway epithelial …

Targeted immunotherapy with recombinant, oncolytic adenoviruses is under investigation for the treatment of cancer. Evidence indicates adenoviruses induce autophagy that is required for oncolysis, but the molecular regulation of autophagy in infected cells remains under investigation. Our data suggested the canonical pathway regulating starvation-induced autophagy was not implemented in adenovirus-induced autophagy; however, adenovirus infection triggered phosphorylation of c-Jun N-terminal kinases (JNK) that was essential for autophagy. Adenoviral replication within the host cell elicited JNK pathway activation leading to B cell lymphoma-2 (Bcl-2) phosphorylation. JNK-dependent Bcl-2 phosphorylation stimulated the dissociation of Bcl-2/beclin 1 heterodimers, enabling beclin 1 to initiate autophagy. Moreover, …

Replication deficient viruses have been used widely for replacing, repairing, and deleting target genes. These recombinant viruses are tested on research animals or patients in clinical trials. Although viral vectors distribute in the body, they are also disseminated into the environment through secretion and excretion processes. By studying the extent of shedding, a proper risk assessment can be performed and appropriate biocontainment can be achieved. Adenoviral and lentiviral vectors were produced from commercially available kits. The transgene present in both vector systems was the lacZ reporter gene encoding for β-galactosidase. Primers and probes were designed for the encapsidation region of …
