Global distribution of the CCR2-641/CCR5-59653T HIV-1 disease-protective haplotype
(2000)Objectives: Several natural polymorphisms in the genes for the human CC-chemokine receptors CCR5 and CCR2 are associated with HIV-1 disease. The CCR2-641 genetic variant [a G to A substitution resulting in a valine (V) to ...

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 ...

Article
HBV-DNA levels predict overall mortality in HIV/HBV coinfected individuals
(2016)The coinfection of Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) has been associated with increased death rates. However, the relevant research has mostly relied on serologic HBV testing [HBV surface antigen ...

HIV epidemiology in Greece
(2008)Greece has experienced early the effect of HIV/AIDS on morbidity and mortality. The era of highly active antiretroviral therapy has alleviated many of the consequences of the epidemic, however, HIV infection remains an ...

HIV-1 integrase: From biology to chemotherapeutics
(2007)AIDS has claimed the lives of 25 million people worldwide, an additional 40 million people are HIV-infected and new cases are being diagnosed every year. Despite the fact that HAART has moved AIDS from the category of ...

HIV-1 outbreak among injecting drug users in Greece, 2011: A preliminary report
(2011)A significant increase (more than 10-fold) in the number of newly diagnosed HIV-1 infections among injecting drug users (IDUs) was observed in Greece during the first seven months of 2011. Molecular epidemiology results ...

Article
HIV-1 subtype distribution and its demographic determinants in newly diagnosed patients in Europe suggest highly compartmentalized epidemics
(2013)Background: Understanding HIV-1 subtype distribution and epidemiology can assist preventive measures and clinical decisions. Sequence variation may affect antiviral drug resistance development, disease progression, ...

Article
HIV-1 vaccine strategies utilizing viral vectors including antigen-displayed inoviral vectors
(2013)Antigen-presenting viral vectors have been extensively used as vehicles for the presentation of antigens to the immune system in numerous vaccine strategies. Particularly in HIV vaccine development efforts, two main viral ...

Article
HIV/AIDS: Recent advances in antiretroviral agents
(2009)Despite the considerable progress in antiretroviral therapy, the eradication of HIV-1 remains unfeasible. Therefore, novel agents are under investigation. The aim of this review is to summarize the conventional compounds, ...

Article
Impact of HIV type 1 DNA levels on spontaneous disease progression: A meta-analysis
(2012)Several studies have reported the prognostic strength of HIV-1 DNA with variable results however. The aims of the current study were to estimate more accurately the ability of HIV-1 DNA to predict progression of HIV-1 ...

Article
The impact of human allelic variation on HIV-1 disease.
(2003)Human allelic variants influence the susceptibility to HIV-1 infection and/or the subsequent rates of disease progression towards AIDS that average ten years, although they vary greatly among infected subjects. In this ...

Implications of HIV-1 M group polymorphisms on integrase inhibitor efficacy and resistance: Genetic and structural in silico analyses
(2009)The extensive polymorphisms among HIV-1 subtypes have been implicated in drug resistance development. Integrase inhibitors represent the latest addition to the treatment of HIV-1, and their efficacy and resistance patterns ...

Article
Limited cross-border infections in patients newly diagnosed with HIV in Europe
(2013)Background: International travel plays a role in the spread of HIV-1 across Europe. It is, however, not known whether international travel is more important for spread of the epidemic as compared to endogenous infections ...

Article
Molecular characterization of HIV type 1 strains from newly diagnosed patients in Cyprus (2007-2009) recovers multiple clades including unique recombinant strains and lack of transmitted drug resistance
(2011)HIV-1 evolution generates substantial genetic diversity among isolates, the majority of which are represented in areas where multiple strains cocirculate. A heterogeneous genetic HIV-1 pool has been found in Cyprus, directing ...

Article
Near full-length genetic analysis of HIV sequences derived from Cyprus: Evidence of a highly polyphyletic and evolving infection
(2009)The molecular epidemiology of HIV-1 infection was previously studied in Cyprus but the degree of HIV-1 diversity has remained indefinable. The main objective of the present study is to examine HIV-1 strains isolated from ...

Article
Patterns of transmitted HIV drug resistance in Europe vary by risk group
(2014)Background: In Europe, a continuous programme (SPREAD) has been in place for ten years to study transmission of drug resistant HIV. We analysed time trends of transmitted drug resistance mutations (TDRM) in relation to the ...

Persistence of episomal HIV-1 infection intermediates in patients on highly active anti-retroviral therapy
(2000)Treatment of HIV-1-infected individuals with a combination of anti- retroviral agents results in sustained suppression of HIV-1 replication, as evidenced by a reduction in plasma viral RNA to levels below the limit of ...
