Viral replication usually requires that innate intracellular lines of defence be overcome, a task usually accomplished by specialized viral gene products. The virion infectivity factor (Vif) protein of human immunodeficiency virus (HIV) is required during ...
Human immunodeficiency virus 1 (HIV-1) expresses several accessory proteins that manipulate various host-cell processes to achieve optimum replicative efficiency. One of them, viral protein U (Vpu), has been shown to interfere with the cellular degradation ...
Human colon carcinoma Caco-2 cell monolayers undergo conversion into cells that share morphological and functional features of M cells when allowed to interact with B lymphocytes. A lymphotropic (X4) HIV-1 strain crosses M cell monolayers and infects under ...
During the early phase of the retroviral life cycle, only a fraction of internalized virions end up integrating their genome into the chromosome, even though the resulting proviruses are almost systematically expressed. Here, we reveal that incoming retrov ...
Translation is a central cellular process in every organism and understanding translation from the systems (genome-wide) perspective is very important for medical and biochem. engineering applications. Moreover, recent advances in cell-wide monitoring tool ...
The Nef protein is an important virulence factor of primate lentiviruses, yet the mechanisms by which it exerts this influence are imperfectly understood. Here, using an inducible system, we demonstrate that Nef increases IL-2 secretion from T cells stimul ...
The Nef protein of human immunodeficiency virus type 1 (HIV-1) promotes virion infectivity through mechanisms that are yet ill defined. Some Nef is incorporated into particles, where it is cleaved by the viral protease between amino acids 57 and 58. The fu ...
HIV-1-infected patients vary considerably by their response to antiretroviral treatment, drug concentrations in plasma, toxic events, and rate of immune recovery. This variability could have a genetic basis. We did a pharmacogenetics study to analyse the a ...
BACKGROUND: Human immunodeficiency virus-1 (HIV-1) infection decreases the cell-surface expression of its cellular receptor, CD4, through the combined actions of Nef, Env and Vpu. Such functional convergence strongly suggests that CD4 downregulation is cri ...
Mycobacterium tuberculosis H37Ra is an attenuated tubercle bacillus closely related to the virulent type strain M. tuberculosis H37Rv. Despite extensive study, the reason for the decreased virulence of M. tuberculosis H37Ra has not been determined. A genom ...
