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 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) ...

Article
A chemokine receptor CCR2 allele delays HIV-1 disease progression and is associated with a CCR5 promoter mutation
(1998)Viral and host factors influence the rate of HIV-1 disease progression. For HIV-1 to fuse, a CD4+ cell must express a co-receptor that the virus can use. The chemokine receptors CCR5 and CXCR4 are used by R5 and X4 viruses, ...

Co-Inheritance of Functional Podocin Variants with Heterozygous Collagen IV Mutations Predisposes to Renal Failure
(2015)BACKGROUND/AIMS: A subset of patients who present with proteinuria and are diagnosed with focal segmental glomerulosclerosis (FSGS) have inherited heterozygous COL4A3/A4 mutations and are also diagnosed with thin basement ...

Article
COL4A3/COL4A4 mutations producing focal segmental glomerulosclerosis and renal failure in thin basement membrane nephropathy
(2007)Mutations in the COL4A3/COL4A4 genes of type IV collagen have been found in ∼40% of cases of thin basement membrane nephropathy, which is characterized by microscopic hematuria and is classically thought to cause proteinuria ...

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 ...

Evidence for association of endothelial cell nitric oxide synthase gene polymorphism with earlier progression to end-stage renal disease in a cohort of Hellens from Greece and Cyprus
(2004)Nitric oxide (NO) is thought to be an important factor in the deterioration of renal function. A variable-number tandem 27-bp repeat in intron 4 of the endothelial cell nitric oxide synthase (NOS3) gene has been found to ...

Article
First and second order statistical texture features in carotid plaque image analysis: preliminary results from ongoing research.
(2011)Carotid plaques have been associated with ipsilateral neurological symptoms. High-resolution ultrasound can provide information not only on the degree of carotid artery stenosis but also on the characteristics of the ...

Article
Genetic variation of DKK3 may modify renal disease severity in ADPKD
(2010)Significant variation in the course of autosomal dominant polycystic kidney disease (ADPKD) within families suggests the presence of effect modifiers. Recent studies of the variation within families harboring PKD1 mutations ...

Article
Genotype-renal function correlation in type 2 autosomal dominant polycystic kidney disease
(2003)Autosomal dominant polycystic kidney disease (ADPKD) is a common Mendelian disorder that affects approximately 1 in 1000 live births. Mutations of two genes, PKD1 and PKD2, account for the disease in approximately 80 to ...

Article
HIV-specific cytotoxic T lymphocytes, HLA-A11, and chemokine-related factors may act synergistically to determine HIV resistance in CCR5 Δ32-negative female sex workers in Chiang Rai, northern Thailand
(2001)Understanding how highly HIV-exposed individuals remain HIV uninfected may be useful for HIV vaccine design and development of new HIV prevention strategies. To elucidate mechanisms associated with resistance to HIV ...

Article
New miRNA profiles accurately distinguish renal cell carcinomas and upper tract urothelial carcinomas from the normal kidney
(2014)Background: Upper tract urothelial carcinomas (UT-UC) can invade the pelvicalyceal system making differential diagnosis of the various histologically distinct renal cell carcinoma (RCC) subtypes and UT-UC, difficult. Correct ...

Article
Non-isotopic RNase cleavage assay for mutation detection in MEFV, the gene responsible for familial Mediterranean fever, in a cohort of Greek patients
(2004)Background: The MEFV gene is responsible for familial Mediterranean fever (FMF). Several disease associated mutations have been identified. The range of genetic variation in MEFV in Greek patients has not been determined. ...

Novel PKD1 deletions and missense variants in a cohort of Hellenic polycystic kidney disease families
(2001)The autosomal dominant form of polycystic kidney disease is a very frequent genetically heterogeneous inherited condition affecting approximately 1: 1000 individuals of the Caucasian population. The main symptom is the ...

A polymorphism in the regulatory region of the CC-chemokine receptor 5 gene influences perinatal transmission of human immunodeficiency virus type 1 to African-American infants
(1999)There are natural mutations in the coding and noncoding regions of the human immunodeficiency virus type (HIV-1) CC-chemokine coreceptor 5 (CCR5) and in the related CCR2 protein (the CCR2-64I mutation). Individuals homozygous ...

Screening for Familial Mediterranean Fever M694V and V726A mutations in the Greek population.
(2009)Familial Mediterranean Fever (FMF) is an autosomal recessive genetic disease that primarily affects populations surrounding the Mediterranean basin. FMF patients suffer from recurrent episodes of fever accompanied by ...
