description

1. 1. The double-stranded RNA-dependent 2′,5′-oligoadenylate (2–5A) synthetase/ribonuclease L (RNase L) system plays an essential role in the establishment of the antiviral state of a cell exposed to virus infection. 2. 2. Until recently, the application of 2–5A derivatives to reinforce this system seemed to be limited mainly due to the low specificity of RNase L for viral RNA. 3. 3. Two new strategies have been developed which yield a selective antiviral effect of 2–5As at least against human immunodeficiency virus-1 (HIV-1) infection: (i) an “intracellular immunization” appproach using 2-5A synthetase cDNA linked to HIV trans -acting response element (TAR) and (ii) inhibition of retroviral reverse transcriptase activity by 2-5A analogues.
