By re-engineering a tiny chain of amino acids in one type of dengue virus, Ralph Baric and Aravinda de Silva discover a new path toward solving the dengue vaccine dilemma. The research has the potential to transform vaccine development for other diseases, including SARS and HIV. Creating a vaccine that protects people from all four types of dengue virus has frustrated scientists for decades. But researchers at the University of North Carolina have discovered a new target for human...

Researchers Identify How Mosquito Immune System Attacks Specific Infections Researchers at the Johns Hopkins Bloomberg School of Public Health have determined a new mechanism by which the mosquitoes´ immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene. Unlike humans and other animals, insects do not make antibodies to target specific infections. According to the Johns Hopkins...

Walter and Eliza Hall Institute researchers have discovered how a key viral gene helps viruses evade early detection by the immune system. Their finding is providing new insights into how viruses are able to establish chronic infections, leading scientists to reevaluate their approaches to viral vaccine development. Researchers from the institute's Immunology division together with collaborators at the University of Cambridge (UK) have been studying how the immune system responds to viruses...

The greater susceptibility of humans to certain infectious diseases when compared to other primates could be explained by species-specific changes in immune signaling pathways, a University of Chicago study finds. The first genome-wide, functional comparison of genes regulated by the innate immune system in three primate species discovers potential mediators of differences in disease susceptibility among primates. These findings are published on December 16 in the open-access journal PLoS...
