Book Description
Sexual transmission of HIV-1 is often established by one genetic variant, the transmitted/founder (T/F) virus. T/F HIV-1 may have specific phenotypic properties that are selected for during transmission. To date, the most consistent phenotypic property associated with T/F viruses is use of the chemokine receptor CCR5 as a coreceptor for entry. Small molecule CCR5 antagonists, such as Maraviroc (MVC), inhibit HIV-1 entry by functioning as allosteric inhibitors. These molecules bind within the transmembrane helices of CCR5, inducing a conformational change that prevents the HIV-CCR5 interaction. As with most drugs, HIV-1 has developed strategies to overcome this inhibition. Some viruses develop mutations in the envelope (Env) glycoprotein that enable the use of antagonist-bound CCR5. In Chapter Two, we evaluate 87 CCR5-using viruses to address differences between T/F viruses and viruses isolated from chronically infected individuals (chronic controls-CC) in their ability to mediate entry via varying amounts of CCR5 in the presence of MVC. We demonstrate that CC viruses exhibit partial resistance (PR) to MVC more frequently than T/F viruses, suggesting that T/F and CC HIV-1 differentially utilize CCR5 in a manner that may be biologically important in the context of transmission. Following the discovery of the chemokine receptors CXCR4 and CCR5 as cofactors for HIV-1 entry, it was revealed that their cognate chemokine ligands could inhibit HIV-1 infection in vitro. Multiple cell types have been implicated in secreting chemokines that function to modulate HIV-1 infection. Recently the platelet-derived chemokine PF4 was shown to inhibit HIV-1. However, despite plasma and local concentrations of PF4 being within the range used in these studies, HIV-1 is still able to propagate in vivo. In Chapter Four, we sought to understand the mechanism of action of PF4 and determine it's in vivo relevance. I confirmed and extended previous studies showing that PF4 inhibits infection by HIV-1 and other viruses. However, the inhibitory capacity of PF4 is limited to a defined concentration range, after which inhibition wanes and viral infection is ultimately enhanced at higher chemokine concentrations that are commonly found in vivo. Thus, rather than being a potential anti-viral agent as previously suggested, PF4 may contribute to the hematologic abnormalities commonly seen in HIV-infected individuals by enhancing virus infection in the bone marrow.

Book Description
The second edition of HIV and the Pathogenesis of AIDS updates this important, well–annotated text on HIV pathogenesis. with valuable insights and written with clarity and succinctness, the history and background of human immunodeficiency virus (HIV) and the steps involved in its infection of cells and the development of AIDS are discussed. Aspects of HIV epidemiology and transmission and the HIV–associated cancers that are prominent in infection are also covered. Regarding treatment, Dr Levy discusses the most recent approaches for antiviral therapy that have shown promise in controling infection and presents the challenges faced in developing a vaccine for blocking the transmission of this deadly virus. This book, which was extremely well–received by the scientific community in its initial volume four years ago, provides the most current information on HIV and AIDS and captures the spirit of this virologic and immunologic disease. It defines the future directions that must be taken to find a solution to this devastating illness.

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
During the last 5 years, major advances have been made in our understanding of the pathogenesis of human immunodeficiency virus (HIV) disease and in the development of new potent antiviral agents. With regard to HIV pathogenesis, several recent observations have not only changed our perspectives of HIV disease, but have been critical for the design of therapeutic strategies.
