Role of CD4 receptor down-regulation during HIV-1 infection.

Abstract:

:Human immunodeficiency virus has evolved several redundant mechanisms to remove its receptor, the CD4 molecule, from the cell surface. Indeed, HIV-1 encodes three proteins, Nef, Vpu and Env, that have a profound effect on CD4 trafficking and catabolism. Given this functional convergence, it is believed that cell surface CD4 regulation constitutes an important determinant of viral replication and pathogenesis in vivo. This review highlights recent progress made in our understanding of the molecular mechanisms underlying the down-regulation of the CD4 receptor by HIV-1 and describes our current comprehension of the role of CD4 down-regulation during HIV-1 infection.

  • Effects of highly active antiretroviral therapy on HIV-1-associated oral complications.

    abstract::The oral cavity of human immunodeficiency virus type I (HIV-1) infected individuals is subjected to a series of opportunistic infections which are usually considered as a prognostic marker for the severity of infection as well as an indicator of immunodeficiency. The highly active antiretroviral therapy (HAART) has si...
