CCL3L1 Copy Number Variation and Susceptibility to HIV-1 Infection: A Meta-Analysis
Background: Although several studies have investigated whether CCL3L1 copy number variation (CNV) influences the risk of HIV-1 infection, there are still no clear conclusions. Therefore, we performed a meta-analysis using two models to generate a more robust estimate of the association between CCL3L1 CNV and susceptibility to HIV-1 infection. Methods: We divided the cases and controls into two parts as individuals with CCL3L1 gene copy number (GCN) above the population specific median copy number (PMN) and individuals with CCL3L1 GCN below PMN, respectively. Odds ratios (ORs) with 95 % confidence intervals (95 % CIs) were given for the main analysis. We also conducted stratified analyses by ethnicity, age group and sample size. Relevant literatures were searched through PubMed and ISI Web of Knowledge up t

Novel immunological strategies for HIV-1 eradication
Abstract Despite the significant advances in antiretroviral therapy (ART), HIV-1 is able to persist in cellular reservoirs. Preclinical studies suggest that the latent reservoir is established within days of virus exposure, even before virus can be detected in peripheral blood. Latently infected cells remain undetectable by the immune system and can persist for years without losing their ability to produce infectious virus when ART is discontinued. Novel concepts for viral eradication strategies combine pharmacological induction of latently infected cells to produce virus together with immune-enhancing interventions to enable the host to clear these cells. In this review, we describe the early establishment of HIV-1 latency and discuss current strategies to disrupt latency and potentially enable clearance of these persistently infected cells
