The Biology of Dendritic Cells and HIV Infection [Paperback]

Dendritic cells play the most vital part in inducing anti-viral immune responses in HIV and AIDS among many other viruses. Research on dendritic cells (DCs) is emerging as a fundamental aspect for the comprehension of the mechanisms underlying the pathogenesis of viral diseases. This volume focuses on the role of DCs in the pathogenesis and immunity of HIV-1 infection. It is the only comprehensive volume on pathogenesis and immunity of Dendritic Cells that also focuses on HIV.

Dendritic cells play the most vital part in inducing anti-viral immune responses in HIV and AIDS among many other viruses. Research on dendritic cells (DCs) is emerging as a fundamental aspect for the comprehension of the mechanisms underlying the pathogenesis of viral diseases as well as for the progress on the development of prophylactic and therapeutic vaccines.

This volume focuses on the role of DCs in the pathogenesis and immunity of HIV-1 infection. It has recently been clarified that DCs are important targets and reservoirs of HIV and may play an important role in virus spreading to T cells. Interestingly, HIV can exploit many of the cellular processes responsible for the generation and regulation of the adaptive immune responses to gain access to its main target cells, i.e. the CD4⁺ T lymphocytes. Thus, the central role of DCs in stimulating T cell activation not only provides a route for viral transmission, but also represents a vulnerable point at which HIV-1 can interfere with the initiation of primary T cell immunity.

Recent studies have revealed that several HIV proteins can profoundly influence the phenotype and functions of DCs even in the absence of a productive infection, often resulting in an abnormal immune response. While this knowledge has resulted in the identification of some major mechanisms involved in the pathogenesis of HIV-1 infection, the reclsÄ
