Dengue-2 virus infection of human mononuclear cell lines and establishment of persistent infections
1990
Twenty three human mononuclear cell lines including ten myelomonocytic cell lines, eight B cell lines and five T cell lines, were examined to determine whether they could be infected with dengue-2 virus. All the cell lines were infected with dengue-2 virus as determined by immunofluorescent staining and by virus titration of culture supernatant fluids. K 562, Jiyoye and Jurkat, respectively, showed the highest percentage of infected cells of these myelomonocytic, B and T cell lines. Antibody to dengue-2 virus at subneutralizing concentrations augmented dengue-2 virus infection of myelomonocytic cell lines, but not of B cell lines or of T cell lines.
