Stable changes in CD4+ T lymphocyte miRNA expression after exposure to HIV-1
2012
Abstract MicroRNAs (miRNAs) inhibit HIV-1 expression by either modulating host innate immunity or by directly interfering with viral mRNAs. We evaluated the expression of 377 miRNAs in CD4+ T cells from HIV-1 élite long-term nonprogressors (éLTNPs), naive patients, and multiply exposed uninfected (MEU) patients, and we observed that the éLTNP patients clustered with naive patients, whereas all MEU subjects grouped together. The discriminatory power of miRNAs showed that 21 miRNAs significantly differentiated éLTNP from MEU patients and 23 miRNAs distinguished naive from MEU patients, whereas only 1 miRNA (miR-155) discriminated éLTNP from naive patients. We proposed that miRNA expression ma…
Changes in CD4+ cells’ miRNA expression following exposure to HIV-1
2010
Background: Micro RNAs (miRNAs) inhibit HIV-1 expression by either modulating host innate immunity or by directly interfering with viral mRNAs. Here, we investigated the miRNA profile that discriminates different classes of HIV-1-infected patients from multiple-exposed uninfected individuals. Methods: The expression levels of 377 miRNAs were selectively analysed in CD4+ cells isolated from whole blood of HIV-1 elite LTNP (eLTNP), naive, and multiply exposed uninfected individuals (MEUs). MiRNA extraction was performed by the mir Vana™ miRNA Isolation Kit (Ambion), and their expression was subsequently examined by real-time PCR-based arrays. The expression of miRNAs was also determined in pr…
