In October 2016, researchers reported that they had achieved sustained SIV remission in monkeys using a monkey antibody similar to the human drug vedolizumab , which is approved by the U.S. Food and Drug Administration for treating ulcerative colitis and Crohn's disease. The mechanism behind this observation has been unclear, but a new report presented today at the Conference on Retroviruses and Opportunistic Infections in Seattle provides clues. Scientists have known that alpha-4 beta-7 integrin is a gut-homing receptor present at high levels on the immune-system cells that HIV and SIV preferentially infect. In the new study, scientists found that maturing HIV and SIV particles acquire alpha-4 beta-7 as they emerge from an infected cell, presenting researchers with a new target for HIV prevention and treatment and shedding light on how HIV disease develops. "We expected the antibody to attack alpha-4 beta-7 on immune cells and reduce their movement to the gut, where HI...

This can be a stylized illustration of a peptide epitope extending from the N-terminal finish of the HLA-I binding groove. Credit score: Imaging CoE Monash College (Australia) and Cardiff College (UK) researchers have come a step additional in understanding how the human immunodeficiency virus (HIV) evades the immune system. Declared a pandemic in 1987 by the World Well being Group, HIV an infection has been chargeable for 39 million deaths over the past 30 years. It stays one of many world's most important public well being challenges and thus a better understanding of how HIV capabilities is urgently wanted in order that researchers can design higher therapies to focus on this devastating pathogen. Revealed in  Nature Structural and Molecular Biology , the Monash-Cardiff crew has made an essential discovering in understanding how HIV-I can evade the immune system. They demonstrated, in molecular element, how mutations inside HIV can result in ...

"The pace of preclinical and early clinical development for Zika vaccines is unprecedented," said Barouch, corresponding author and director of the Center for Virology and Vaccine Research at BIDMC. "In less than a year, our group and others have demonstrated that multiple vaccine platforms can provide robust protection against Zika virus challenge in animal models. However, unique challenges will need to be addressed in the clinical development of a Zika vaccine. " The recent outbreak of the Zika virus in the Americas began in Brazil nearly two years ago. By February 2016, the World Health Organization had declared the epidemic a global public health emergency, based largely on the virus' newly-established link to microcephaly and other major birth defects in babies born to infected mothers. The virus has also been associated with the neurologic disorder Guillain-Barré syndrome in adults. In a previously published paper, Barouch and colleagues, including Co...
