Targeting apolipoprotein E could be key to eliminating hepatitis B virus

Human apolipoprotein E (apoE) promotes hepatitis B virus (HBV) infection and production, according to a study published Aug 8 in the open-access journal PLOS Pathogens by Luhua Qiao and Guangxiang (George) Luo of the University of Alabama at Birmingham School of Medicine. The findings suggest that inhibitors interfering with apoE biogenesis, secretion, and/or binding to

Lung neuropeptide exacerbates lethal influenza virus infection: Researchers find that neuropeptide Y (NPY) makes influenza worse when produced by lung immune cells

Severe influenza virus infection is characterized by a strong inflammatory response and profuse viral replication in lungs. These viruses, such as the notorious avian flu, have a high rate of death and to date there are no effective treatments. A research group led by National Institutes of Biomedical Innovation, Health and Nutrition (NIBIOHN) and Osaka

Discovery could neutralize West Nile virus

Researchers at Vanderbilt University Medical Center and colleagues have isolated a human monoclonal antibody that can “neutralize” the West Nile virus and potentially prevent a leading cause of viral encephalitis (brain inflammation) in the United States. Their findings, reported this week in the journal Nature Microbiology, could lead to the first effective treatment for this

Synthetic DNA-delivered antibodies protect against Ebola in preclinical studies

Scientists at The Wistar Institute and collaborators have successfully engineered novel DNA-encoded monoclonal antibodies (DMAbs) targeting Zaire Ebolavirus that were effective in preclinical models. Study results, published online in Cell Reports, showed that DMAbs were expressed over a wide window of time and offered complete and long-term protection against lethal virus challenges. DMAbs may also

New antibody analysis accelerates rational vaccine design: Scripps Research study illuminates humoral immune response to experimental vaccines

A team at Scripps Research has come up with a faster way to analyze the outcome of experimental vaccines against HIV and other pathogens. Their new system lets scientists quickly assess the full spectrum of antibodies produced in an individual in response to a pathogen or vaccine and determine if these antibodies are likely to

Dogs can be a potential risk for future influenza pandemic

Dogs are a potential reservoir for a future influenza pandemic, according to a study published in the journal mBio. The study demonstrated that influenza virus can jump from pigs into canines and that influenza is becoming increasingly diverse in canines. “The majority of pandemics have been associated with pigs as an intermediate host between avian

Characteristics of microorganisms most likely to cause a global pandemic

Infectious disease preparedness work focuses predominantly on an historical list of pathogens derived from biological warfare agents, political considerations, and recent outbreaks. That fails to account for the most serious agents not currently known or without historical precedent, write scholars from the Johns Hopkins Center for Health Security in a new report on the traits
