Interaction of human adenovirus serotype 2 with human lymphoid cells.

Human adenoviruses (e.g., Ad2, Ad5) establish chronic infections in human lymphoid-derived cell lines, including Raji and Jijoye (R.E. Wallace, 1969, Proc. Soc. Exp. Biol. Med. 130, 702-710; N. Faucon, G. Ogier, and Y. Chardonnet, 1982, J. Natl. Cancer Inst. 69, 1215-1220); however, the mechanisms by which chronic infections are established and maintained are not understood. When Raji or MOLT-3 cell cultures were infected with Ad2 at high multiplicity, these cell lines continued to grow exponentially and produced only small amounts of infectious virus. Virus-specific antigens, including the DNA-binding protein and hexon, were expressed in only 5% of the Ad2-inoculated cultures. All Raji and MOLT-3 cells were found to have adenovirus receptors, but the Ad2 virions that adsorbed to most Raji cells were sequestered in caps, suggesting that most cells fail to internalize adsorbed Ad2. Cell synchronization experiments showed a correlation between the proportion of cells that became productively infected and the proportion of cells in mitosis at the time of infection. In contrast, primary blood lymphocytes had few, if any, Ad2 receptors and were not productively infected by Ad2.
