Area of Science:

  • Immunology
  • Virology
  • Genomics

Background:

  • Human Immunodeficiency Virus (HIV) infection leads to immune dysregulation.
  • Microarray studies analyze gene expression changes in immune cells during HIV infection.
  • Understanding HIV's impact on various immune cells is crucial for developing effective treatments.

Purpose of the Study:

  • To review 34 HIV microarray studies published between 2000 and March 2006.
  • To emphasize analytical approaches and conceptual advances in HIV gene modulation research.
  • To explore HIV's impact on target (CD4 T cells, macrophages) and non-target immune cells (NK, B, dendritic cells).

Main Methods:

  • Systematic review of 34 HIV microarray studies.
  • Analysis of gene modulation in various human immune cell subsets.

  • Focus on studies involving HIV-1 virus or accessory protein exposure (in vitro/in vivo).

    • Main Results:

    • Gene modulation is linked to immune dysregulation, apoptosis, viral replication, and persistence.
    • Novel mechanisms include cholesterol biosynthesis gene modulation in CD4 T cells.
    • Proteasome and histone deacetylase modulation in infected cells suggests roles in HIV latency.

    Conclusions:

    • Microarray studies provide valuable data on HIV-1 pathogenesis.
    • Challenges remain in data integration and validation.
    • Progress continues in identifying validated genes and understanding functional correlates of gene modulation in HIV-1 pathogenesis.
