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 Synopsis Chemokines and Viral Infection by : Thomas E. Lane
Download or read book Chemokines and Viral Infection written by Thomas E. Lane and published by Springer Science & Business Media. This book was released on 2007-05-30 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemokines represent a family of over 40 small proteins that, for the most part, are secreted into the environment and function by binding to G protein-coupled receptors (GPCRs) that are expressed on numerous different cell types. When initially identified close to 30 years ago, these molecules were associated with various human inflammatory diseases and it was recognized that expression may be integral in leukocyte recruitment to inflamed tissue. Within a relatively short period of time, early participants within the field determined that these proteins displayed distinct and conserved structural features and exerted potent chemotactic effects on defined lymphocyte subsets. There are now four sub-families of chemokines identified based on defined structural criteria relating to the positional location of conserved cysteine residues within the amino-terminus of the protein. Chemokines are now recognized as important in numerous biological processes ranging from maintaining the organizational integrity of secondary lymphoid tissue to participating in various aspects of both innate and adaptive immune responses following microbial infection.

Book Synopsis Nutrition and HIV by : Saurabh Mehta
Download or read book Nutrition and HIV written by Saurabh Mehta and published by CRC Press. This book was released on 2018-05-15 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world continues to lose more than a million lives each year to the HIV epidemic, and nearly two million individuals were infected with HIV in 2017 alone. The new Sustainable Development Goals, adopted by countries of the United Nations in September 2015, include a commitment to end the AIDS epidemic by 2030. Considerable emphasis on prevention of new infections and treatment of those living with HIV will be needed to make this goal achievable. With nearly 37 million people now living with HIV, it is a communicable disease that behaves like a noncommunicable disease. Nutritional management is integral to comprehensive HIV care and treatment. Improved nutritional status and weight gain can increase recovery and strength of individuals living with HIV/AIDS, improve dietary diversity and caloric intake, and improve quality of life. This book highlights evidence-based research linking nutrition and HIV and identifies research gaps to inform the development of guidelines and policies for the United Nations’ Sustainable Development Goals. A comprehensive approach that includes nutritional interventions is likely to maximize the benefit of antiretroviral therapy in preventing HIV disease progression and other adverse outcomes in HIV-infected men and women. Modification of nutritional status has been shown to enhance the quality of life of those suffering HIV/AIDS, both physically in terms of improved body mass index and immunological markers, and psychologically, by improving symptoms of depression. While the primary focus for those infected should remain on antiretroviral treatment and increasing its availability and coverage, improvement of nutritional status plays a complementary role in the management of HIV infection.
Book Synopsis Chimpanzees in Biomedical and Behavioral Research by : National Research Council
Download or read book Chimpanzees in Biomedical and Behavioral Research written by National Research Council and published by National Academies Press. This book was released on 2011-12-05 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, experiments using chimpanzees have been instrumental in advancing scientific knowledge and have led to new medicines to prevent life-threatening and debilitating diseases. However, recent advances in alternate research tools have rendered chimpanzees largely unnecessary as research subjects. The Institute of Medicine, in collaboration with the National Research Council, conducted an in-depth analysis of the scientific necessity for chimpanzees in NIH-funded biomedical and behavioral research. The committee concludes that while the chimpanzee has been a valuable animal model in the past, most current biomedical research use of chimpanzees is not necessary, though noted that it is impossible to predict whether research on emerging or new diseases may necessitate chimpanzees in the future.
