Book Description
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.

Book Description
Given rapid research progress and advance of the techniques in studying HIV interactions with host cells and factors, there is a critical need for a book on HIV interactions with DCs. The proposed book will aim for a broad readership to facilitate HIV/AIDS research and provide a practical tool for HIV researchers to continuously address novel questions. Specifically, the editors will summarize the literature in this field and provide critical analysis and future directions. International researchers will be invited as contributors of the book, highlighting authors who have contributed significantly to the field from different angles and aspects of virology, cell biology and immunology, etc.

Book Description
Dendritic cells are vital to induce potent anti-viral immune responses. It will become clear to the reader that dendritic cells often play a dual role during viral infections. On the one hand they are able to mount potent antiviral immune responses, and on the other hand several viruses, including HIV-1, use DC as a vector to be transferred from the periphery to the lymph nodes where they infect their prime target.

Book Description
Cellular Aspects of HIV Infection provides a highly readable, detailed overview of the state of the art in modern HIV research at the cellular level. This volume brings together renowned experts who have provided concise, synthetic treatments of the biology of HIV infection. It presents these descriptions and analyses with particular attention to the techniques of flow cytometry that have allowed us to not only observe the course of HIV infection and the immune system's response to it, but have also increased our ability to treat patients and understand their response to therapy. The book is divided into five sections covering molecules and cells, pathophysiological processes, technologies, and organisms. A perspective on future therapies concludes the book. Each chapter offers an intelligent, concise synthesis of the topic, highlighting the biological principles and technologies involved in the study of HIV infection. Cellular Aspects of HIV Infection is an indispensable, up-to-date guide for immunologists, virologists, clinicians, and researchers.

Book Description
Dendritic cells are key players during HIV pathogenesis, and shape both the immediate immune response at the site of infection as well as directing the adaptive immune response against the virus. HIV has developed a plethora of immune evasion mechanisms that hijack dendritic cell functions, suppressing their ability to mount an accurate immune response and exploiting them for efficient viral transfer to target T cells. To achieve successful replication within dendritic cells without triggering danger signaling, HIV accomplishes a delicate balance where only a low level of transcription can be sustained without triggering antiviral responses that would harm the virus. Here, we describe how the presence of HSV2 coinfection, which is very common in geographic areas with a high HIV prevalence and almost triples the risk of HIV acquisition, alters dendritic cell state to support much higher levels of HIV infection. We found this effect to be mediated by the STING pathway, which is involved in the sensing of DNA in the cell cytosol. STING activation led to an upregulation of factors such as IRF3 and NFkB that can be used for HIV transcription and a degradation of factors that restrict HIV replication. In addition, we describe how HIV exploits the human complement system, a group of proteins that usually help the human body to identify dangerous pathogens while avoiding reaction towards self. HIV can coat itself, i.e. become opsonized, in complement fragments that are typically only present on the body’s own cells, allowing it to activate signaling pathways that are associated with tolerance. Dendritic cells that come into contact with complement opsonized HIV do not mount danger responses, despite the fact that HIV-derived single stranded RNA triggers the pathogen recognition receptor TLR8. The suppression of danger responses is mediated by activation of complement receptor 3, and leads to an increased infection of the dendritic cell and affects its interactions with other immune cells. There is a lack of recruitment of NK cells to the site of infection, and an inhibition of NK cell killing, which plays an important role in the destruction of HIV-infected cells in vivo. T cells primed by dendritic cells exposed to complement opsonized HIV have a lower ability to develop towards effector phenotype, and have an increased expression of the markers PD1, TIM3 and LAG3 which are associated with T cell dysfunction and exhaustion. In addition, T cells primed by these dendritic cells in the presence of NK cells upregulate markers CD38, CXCR3 and CCR4, which have been linked to an increased susceptibility to HIV infection. In summary, we add to the current knowledge on HIV immune evasion mechanisms that allow the virus to establish infection, as well as describing mechanisms that govern whether dendritic cells mount danger signaling and an immune response or not.

Book Description
These proceedings contain selected contributions from the participants to the Fourth International Symposium on Dendritic cells that was held in Venice (Lido) Italy, from Oc tober 5 to 10, 1996. The symposium was attended by more than 500 scientists coming from 24 different countries. Studies on dendritic cells (DC) have been greatly hampered by the difficulties in preparing sufficient cell numbers and in a reasonable pure form. At this meeting it has been shown that large quantities of DC can be generated from precursors in both mice and humans, and this possibility has enormously encouraged studies aimed to characterize DC physiology and DC-specific genes, and to employ DC therapeutically as adjuvants for im munization. The possibility of generating large numbers of autologous DC that can be used in the manipulation of the immune response against cancer and infectious diseases has tremendously boosted dendritic cell research and the role of DC in a number of medi cal areas has been heatedly discussed.
