A simple feedback resistor switch keeps latent HIV from awakening

sistor," and its general features, the authors suggest, are likely to be found in other systems that must rapidly alternate between two states while resisting noise in the environment. Their model may also provide an explanation for some puzzling observations about Tat and HIV. Tat contains at least two acetylation sites that must both be deacetylated to turn off transcription. The authors propose this requirement may avoid making the off state so easy to reach that the virus remains dormant all the time. This model also helps explain why some HIV patients experience short "blips" of viral activity, despite relatively low viral concentration. According to the authors, these pulses of viral activation may be due either to random increases of Tat activity or to environmental inhibitors of the SirT1 enzyme, such as dihydrocoumarin, a natural flavoring agent found in clover.
