Dynamics of T- and B-lymphocyte turnover in a natural host of simian immunodeficiency virus.
Increased lymphocyte turnover is a hallmark of pathogenic lentiviral infection. To investigate perturbations in lymphocyte dynamics in natural hosts with nonpathogenic simian immunodeficiency virus (SIV) infection, the nucleoside analog bromodeoxyuridine (BrdU) was administered to six naturally SIV-infected and five SIV-negative sooty mangabeys. As a measure of lymphocyte turnover, we estimated...
متن کاملParallel evolution of CCR5-null phenotypes in humans and in a natural host of simian immunodeficiency virus
The C-C chemokine receptor CCR5 in humans and rhesus macaques (Macaca mulatta) serves as the primary coreceptor for cellular entry by macrophagetropic strains of human immunodeficiency virus type 1 (HIV-1) and all reported strains of simian immunodeficiency virus (SIV) [1-6]. Humans homozygous for a 32 bp deletion allele of CCR5, resulting in a null phenotype, are highly resistant to infection ...
متن کاملA spatio-temporal assessment of simian/human immunodeficiency virus (SHIV) evolution reveals a highly dynamic process within the host
The process by which drug-resistant HIV-1 arises and spreads spatially within an infected individual is poorly understood. Studies have found variable results relating how HIV-1 in the blood differs from virus sampled in tissues, offering conflicting findings about whether HIV-1 throughout the body is homogeneously distributed. However, most of these studies sample only two compartments and few...

متن کاملBacillus subtilis as a Host for Recombinant Hemagglutinin Production of the Influenza A (H5N1) Virus
Abstract Background and Aims: Influenza A(H5N1) viruses circulating in animals might evolve and acquire the ability to spread from human to human and thus start a pandemic. Hemagglutinin (HA) has been shown to play a major role in binding of influenza virus to its target cell and the main neutralizing antibody responses elicit against this region. Recent studies have shown that...
