This book was released on 2015 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: During the past two decades, the world scientific community has witnessed major achievements in our understanding of the pathogenesis of HIV infection of the nervous system and HIV-Associated Dementia (HAD). Despite these giant gains, nervous system involvement during AIDS remains a relentlessly progressive disease with a deadly fate in many cases. This book on NeuroAIDS provides a unique resource for both general neurologists as well as basic neuroscientists with profound interests for research on NeuroAIDS. This book has special emphasis on the mechanisms of disease development and progression of HIV-infected patients with NeuroAIDS. The contributors have provided the readers with comprehensive reviews on clinical manifestations of HAD, mechanisms of HIV entry into the central nervous system, the role of cytokines and chemokines in pathogenesis of NeuroAIDS, drug abuse and NeuroAIDS, virus load in HAD, allostasis in HIV and AIDS, stroke in AIDS patients, and neuroimaging of HIV infection of the central nervous system. In addition, there are chapters on Varicella Zoster virus infection of HIV-seropositive and AIDS patients, as well as the molecular basis for opioids and AIDS virus interactions.

Available in PDF, EPUB and Kindle. Book excerpt: The history of the CCR5 gene as a lens through which to view such issues as intellectual property, Big Pharma, personalized medicine, and race and genomics. In The Genealogy of a Gene, Myles Jackson uses the story of the CCR5 gene to investigate the interrelationships among science, technology, and society. Mapping the varied “genealogy” of CCR5—intellectual property, natural selection, Big and Small Pharma, human diversity studies, personalized medicine, ancestry studies, and race and genomics—Jackson links a myriad of diverse topics. The history of CCR5 from the 1990s to the present offers a vivid illustration of how intellectual property law has changed the conduct and content of scientific knowledge, and the social, political, and ethical implications of such a transformation. The CCR5 gene began as a small sequence of DNA, became a patented product of a corporation, and then, when it was found to be an AIDS virus co-receptor with a key role in the immune system, it became part of the biomedical research world—and a potential moneymaker for the pharmaceutical industry. When it was further discovered that a mutation of the gene found in certain populations conferred near-immunity to the AIDS virus, questions about race and genetics arose. Jackson describes these developments in the context of larger issues, including the rise of “biocapitalism,” the patentability of products of nature, the difference between U.S. and European patenting approaches, and the relevance of race and ethnicity to medical research.

Download or read book The CCL3L1 CCR5 Genotype Influences the Development of AIDS But Not HIV Susceptibility Or the Response to HAART written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A selective advantage against infectious diseases such as HIV/AIDS is associated with differences in the genes relevant to immunity and virus replication. The CC chemokine receptor 5 (CCR5), the principal coreceptor for HIV, and its chemokine ligands, including CCL3L1, influences the CD4+ target cells susceptibility to infection. The CCL3L1 gene is in a region of segmental duplication on the q-arm of human chromosome 17. Increased numbers of CCL3L1 gene copies that affect the gene expression phenotype might have substantial protective effects. Here we show that the population-specific CCL3L1 gene copy number and the CCR5 [Delta]32 protein-inactivating deletion that categorizes the CCL3L1-CCR5 genotype do not influence HIV/AIDS susceptibility or the robustness of immune recovery after the initiation of highly active antiretroviral therapy (HAART).
