Abstract
Cell-mediated immune responses are important for the control of HIV replication in vivo. Cytotoxic CD8+ T cells (CTL) recognize and kill HIV-infected cells which display MHC class-I proteins. In addition to the recognition and killing of infected cells, CD8+T cells can interfere with stages of the HIV life-cycle. Chemokines produced by CD8+ T cells bind to their seven-transmembrane G protein-coupled receptors resulting in a block in the entry of HIV into macrophages and T cells. In addition, activated CD8+ T cells produce factors which strongly modulate HIV at the level of transcription. This review will focus primarily on the current knowledge of the multifactorial functions of CD8+ T cells in HIV infection. An understanding of the mechanisms involved in the CD8-mediated control of transcription may identify other factors with potential value in the treatment of HIV infection.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
