Architectural insight into inovirus-associated vectors (IAVs) and development of IAV-based vaccines inducing humoral and cellular responses: Implications in HIV-1 vaccines
(2014)Inovirus-associated vectors (IAVs) are engineered, non-lytic, filamentous bacteriophages that are assembled primarily from thousands of copies of the major coat protein gp8 and just five copies of each of the four minor ...

CCR5 promoter polymorphisms in a Kenyan perinatal human immunodeficiency virus type 1 cohort: Association with increased 2-year maternal mortality
(2001)The CCR5 chemokine receptor acts as a coreceptor with CD4 to permit infection by primary macrophage-tropic human immunodeficiency virus type 1 (HIV-1) strains. The CCR5Δ32 mutation, which is associated with resistance to ...

Cellular HIV-1 DNA levels in drug sensitive strains are equivalent to those in drug resistant strains in newly-diagnosed patients in Europe
(2010)Background HIV-1 genotypic drug resistance is an important threat to the success of antiretroviral therapy and transmitted resistance has reached 9% prevalence in Europe. Studies have demonstrated that HIV-1 DNA load in ...

Cellular HIV-1 DNA load predicts HIV-RNA rebound and the outcome of highly active antiretroviral therapy
(2004)Objective: To assess whether cellular HIV-1 DNA prior to highly active antiretroviral therapy (HAART) initiation predicts its outcome. Design and methods: Patients included all 51 hemophiliacs of the Greek component of the ...

Changes in T Cell Receptor Excision DNA Circle (TREC) Levels in HIV Type 1-Infected Subjects Pre- and Post-Highly Active Antiretroviral Therapy
(2004)The T cell receptor excision DNA circle (TREC) level is an independent predictor of HIV-1 disease prognosis. We studied the temporal changes in TREC levels prior to and after highly active antiretroviral therapy (HAART) ...

Condom effectiveness in reducing heterosexual HIV transmission: a systematic review and meta-analysis of studies on HIV serodiscordant couples
(2016)Objective: This systematic review and meta-analysis aimed to reassess the effectiveness of condoms in reducing heterosexual transmission of HIV. Methods: Medline, Scopus, and the ISI Web of Science databases were searched ...

Article
CXCR4 mediates entry and productive infection of syncytia-inducing (x4) hiv-1 strains in primary macrophages
(2000)CCR5 and CXCR4 are the main coreceptors for non-syncytia-inducing (NSI) and syncytia-inducing (SI) HIV-1 strains, respectively. NSI HIV-1 isolates do not infect either human lymphoid or monocytoid cell lines, and this ...

Article
Economic recession and emergence of an HIV-1 outbreak among drug injectors in Athens metropolitan area: A longitudinal study
(2013)Background: During 2011, a dramatic increase (1600%) of reported HIV-1 infections among injecting drug users (IDUs) was noted in Athens, Greece. We herein assess the potential causal pathways associated with this outbreak. ...

Effect of hepatitis C virus on immunological and virological responses in HIV-infected patients initiating highly active antiretroviral therapy: A meta-analysis
(2013)Co-infection of human immunodeficiency virus (HIV) with hepatitis C virus (HCV) is rather common. In the era of highly active antiretroviral therapy (HAART), viral hepatitis could result in adverse outcomes in HIV+ patients. ...

Article
Effect of recent thymic emigrants on progression of HIV-1 disease
(2000)Background. The concentration of T-cell receptor-rearrangement excision DNA circles (TREC) in peripheral-blood T cells is a marker of recent thymic emigrant αβ T cells. We studied the predictive ability of measurements of ...

Article
Effects of CCR5-Δ32, CCR2-64I, and SDF-1 3′ a alleles on HIV-1 disease progression: An international meta-analysis of individual-patient data
(2001)Background: Studies relating certain chemokine and chemokine receptor gene alleles with the outcome of HIV-1 infection have yielded inconsistent results. Objective: To examine postulated associations of genetic alleles ...

Article
Emergence of drug-resistant HIV-1 variants in patients undergoing structured treatment interruptions
(2002)We report the emergence of drug-resistant viral mutations in chronically HIV-infected individuals undergoing structured treatment interruptions (STI). The protease mutation M46L and the reverse transcriptase mutations K101E ...

Article
Emergence of Minor Populations of Human Immunodeficiency Virus Type 1 Carrying the M184V and L90M Mutations in Subjects Undergoing Structured Treatment Interruptions
(2003)The use of structured treatment interruption (STI) in human immunodeficiency virus (HIV)-infected subjects is currently being studied as an alternative therapeutic strategy for HIV-1. The potential risk for selection of ...

Epidemiology of aids defining conditions in Greece
(2004)Objective: To examine the secular trends of all AIDS opportunistic infections to occur first (Ols) in Greece, by year, by gender and by mode of transmission. Methods: The study included all AIDS defining conditions reported ...

Evidence for recent selection of the CCR5-Δ32 deletion from differences in its frequency between Ashkenazi and Sephardi Jews
(2000)Recent studies have shown higher frequencies of the CCR5-Δ32 allele and the CCR5-A32/Δ32 genotype, which confers protection against HIV infection, in northern Europe as compared to Mediterranean countries. Here, we analyse ...

Article
Evidence of two distinct subsubtypes within the HIV-1 subtype A radiation
(2001)Members of HIV-1 group M are responsible for the vast majority of AIDS cases worldwide and have been classified on the basis of their phylogenetic relationships into nine roughly equidistant clades, termed subtypes. Although ...

Genetic analysis of HIV type 1 strains from newly infected untreated patients in cyprus: high genetic diversity and low prevalence of drug resistance.
(2009)Abstract The molecular epidemiology of HIV-1 infection was first studied in Cyprus in the mid-1990s, but the extent of HIV-1 diversity and the prevalence of drug resistance have remained elusive. In an effort to address ...

Article
Global genetic variation of HIV-1 infection
(2006)Variability, both at the population (interhost) as well as at the individual (intrahost) level is a key property of HIV that stems mainly from the inherent infidelity of the reverse transcriptase enzyme that the virus uses ...
