Sažetak
Human adenoviruses (HAdVs) are being explored as vectors for gene transfer and vaccination. Human adenovirus type 26 (HAdV26), which belongs to the largest subgroup of adenoviruses, species D, has a short fiber and a so far unknown natural tropism. Due to its low seroprevalence, HAdV26 has been considered a promising vector for the development of vaccines. Despite the fact that the in vivo safety and immunogenicity of HAdV26 has been extensively studied, the basic biology of this virus, with regard to receptor use, cell attachment, internalization and intracellular trafficking is poorly understood. In this work we investigated the role of the coxsackie- and adenovirus receptor (CAR), CD46 and αv integrins in HAdV26 infection of human epithelial cell lines. By performing different gain- and loss-of-function studies we found that αvβ3 integrin is required for efficient infection of epithelial cells by HAdV26, while CAR and CD46 did not increase transduction efficiency of HAdV26. By studying intracellular trafficking of fluorescently labeled HAdV26 in A549 cells and A549-derived cell clones with stably increased expression of αvβ3 integrin, we observed that HAdV26 co-localizes with αvβ3 integrin and that increased αvβ3 integrin enhances internalization of HAdV26. Thus we conclude that HAdV26 uses αvβ3 integrin as a receptor for infecting epithelial cells. These results give us new insight into the HAdV26 infection pathway and will be helpful in further defining HAdV-based vector manufacturing and vaccination strategies
