IL28B Genotype Does Not Correlate with HIV Control in African Americans

In HIV/HCV coinfected patients dendritic cell activation state is not associated with IL28B genotype.

Anti-hepatitis C virus (HCV) treatment in patients infected with human immunodeficiency virus (HIV) has become a focus of recent clinical investigations. HCV treatment efficacy appears to be dependent on the patient’s immunological status at the baseline, with the response rate being directly proportional to the pretreatment CD4 cell count [1, 2]. In HCV monoinfected individuals, a strong assoc...

Host determinants of HIV-1 control in African Americans.

We performed a whole-genome association study of human immunodeficiency virus type 1 (HIV-1) set point among a cohort of African Americans (n = 515), and an intronic single-nucleotide polymorphism (SNP) in the HLA-B gene showed one of the strongest associations. We use a subset of patients to demonstrate that this SNP reflects the effect of the HLA-B*5703 allele, which shows a genome-wide stati...

The Genotype Specific Competitive Ability Does Not Correlate with Infection in Natural Daphnia magna Populations

BACKGROUND Different evolutionary hypotheses predict a correlation between the fitness of a genotype in the absence of infection and the likelihood to become infected. The cost of resistance hypothesis predicts that resistant genotypes pay a cost of being resistant and are less fit in the absence of parasites. The inbreeding-infection hypothesis predicts that the susceptible individuals are les...

Lung cancer risk and CYP1A1 genotype in African Americans.

The role of CYP1A1 genotype in lung cancer risk was assessed in African Americans through a case control study. The complete CYP1A1 genotype, including the frequency of all three polymorphisms (Msp1 [CYP1A1*2], exon 7 [CYP1A1*3] and African American specific [CYP1A1*4]) was determined by PCR on 307 controls and 105 cases of lung cancer among African Americans. We have confirmed our earlier obse...
