Oligodeoxynucleotides (ODNs) containing a variable number of 3' and 5' terminal phosphorothioate linkages were applied in free solution to cells infected by HIV-1. ODNs of 28 nt length were applied at up to 5 microM concentration. The ODNs were found to inhibit HIV-1 infection in a dose dependent manner, which correlated with the number of modified linkages (4, 8 and 12, respectively). A target sequence in the HIV-1 rev mRNA, previously reported as sensitive to antisense inhibition by full length phosphorothioate ODNs, only revealed non-sequence dependent inhibition of HIV-1, when tested by these modified chimers.

D002678 Chimera An individual that contains cell populations derived from different zygotes. Hybrids,Chimeras,Hybrid
D003588 Cytopathogenic Effect, Viral Visible morphologic changes in cells infected with viruses. It includes shutdown of cellular RNA and protein synthesis, cell fusion, release of lysosomal enzymes, changes in cell membrane permeability, diffuse changes in intracellular structures, presence of viral inclusion bodies, and chromosomal aberrations. It excludes malignant transformation, which is CELL TRANSFORMATION, VIRAL. Viral cytopathogenic effects provide a valuable method for identifying and classifying the infecting viruses.
