Abstract: Epstein-Barr virus (EBV) is a ubiquitous human herpesvirus linked to a number of B cell cancers and lymphoproliferative disorders. During latent infection, EBV expresses 25 viral pre-microRNAs (miRNAs) and induces the expression of specific host miRNAs, such as miR-155 and miR-21, which potentially play a role in viral oncogenesis. To date, only a limited number of EBV miRNA targets have been identified; thus, the role of EBV miRNAs in viral pathogenesis and/or lymphomagenesis is not well defined. Here, we used photoactivatable ribonucleoside-enhanced crosslinking and immunoprecipitation (PAR-CLIP) combined with deep sequencing and computational analysis to comprehensively examine the viral and cellular miRNA targetome in EBV strain B95-8-infected lymphoblastoid cell lines (LCLs). We identified 7,827 miRNA-interaction sites in 3,492 cellular 3'UTRs. 531 of these sites contained seed matches to viral miRNAs. 24 PAR-CLIP-identified miRNA:3'UTR interactions were confirmed by reporter assays. Our results reveal that EBV miRNAs predominantly target cellular transcripts during latent infection, thereby manipulating the host environment. Furthermore, targets of EBV miRNAs are involved in multiple cellular processes that are directly relevant to viral infection, including innate immunity, cell survival, and cell proliferation. Finally, we present evidence that myc-regulated host miRNAs from the miR-17/92 cluster can regulate latent viral gene expression. This comprehensive survey of the miRNA targetome in EBV-infected B cells represents a key step towards defining the functions of EBV-encoded miRNAs, and potentially, identifying novel therapeutic targets for EBV-associated malignancies..

Abstract: HIV continues to spread globally, mainly through sexual contact. Despite advances in treatment and care, preventing transmission with vaccines or microbicides has proven difficult. A promising strategy to avoid transmission is prophylactic treatment with antiretroviral drugs before exposure to HIV. Clinical trials evaluating the efficacy of daily treatment with the reverse transcriptase inhibitors tenofovir disoproxil fumarate (TDF) or Truvada (TDF plus emtricitabine) are under way. We hypothesized that intermittent prophylactic treatment with long-acting antiviral drugs would be as effective as daily dosing in blocking the earliest stages of viral replication and preventing mucosal transmission. We tested this hypothesis by intermittently giving prophylactic Truvada to macaque monkeys and then exposing them rectally to simian-human immunodeficiency virus (SHIV) once a week for 14 weeks. A simple regimen with an oral dose of Truvada given 1, 3, or 7 days before exposure followed by a second dose 2 hours after exposure was as protective as daily drug administration, possibly because of the long intracellular persistence of the drugs. In addition, a two-dose regimen initiated 2 hours before or after virus exposure was effective, and full protection was obtained by doubling the Truvada concentration in both doses. We saw no protection if the first dose was delayed until 24 hours after exposure, underscoring the importance of blocking initial replication in the mucosa. Our results show that intermittent prophylactic treatment with an antiviral drug can be highly effective in preventing SHIV infection, with a wide window of protection. They strengthen the possibility of developing feasible, cost-effective strategies to prevent HIV transmission in humans..

Abstract: Naringenin, a flavonoid, has antiinflammatory and immunomodulatory properties. We investigated whether naringenin could attenuate allergen-induced airway inflammation and its possible mechanism in a murine model of asthma. Mice were sensitized and challenged with ovalbumin. Some mice were administered with naringenin before ovalbumin challenge. We evaluated the development of airway inflammation and airway reactivity. Interleukin (IL)4, IL13, chemokine (C-C motif) ligand (CCL)5, and CCL11 in bronchoalveolar lavage fluid and serum total IgE were detected by ELISA. IkappaBalpha degradation and inducible nitric oxide synthase (iNOS) in lungs were measured by Western blot. We also tested NF-kappaB binding activity by electrophoretic mobility shift assay. The mRNA levels of iNOS, CCL5, and CCL11 were detected by real-time PCR. Naringenin attenuated ovalbumin-induced airway inflammation and airway reactivity in experimental mice. The naringenin-treated mice had lower levels of IL4 and IL13 in the bronchoalveolar lavage fluid and lower serum total IgE. Furthermore, naringenin inhibited pulmonary IkappaBalpha degradation and NF-kappaB DNA-binding activity. The levels of CCL5, CCL11, and iNOS were also significantly reduced. The results indicated that naringenin may play protective roles in the asthma process. The inhibition of NF-kappaB and the decreased expression of its target genes may account for this phenomenon..
