- Flaviviruses such as dengue encode a protease that is essential for viral replication. The protease functions by cleaving well-conserved positions in the viral polyprotein. In addition to the viral polyprotein, the dengue protease cleaves at least
Historically, the evolution of bats has been analyzed using a small number of genetic loci for many species or many genetic loci for a few species. Here we present a phylogeny of 18 bat species, each of which is represented in 1,107 orthologous gene
Pandemic HIV-1 (group M) emerged following the cross-species transmission of a simian immunodeficiency virus from chimpanzees (SIVcpz) to humans. Primate lentiviruses (HIV/SIV) require the T cell receptor CD4 to enter into target cells. By surveying
RNA viruses are a major source of emerging and re-emerging infectious diseases around the world. We developed a method to identify RNA viruses that is based on the fact that RNA viruses produce double-stranded RNA (dsRNA) while replicating.

NIH’s awards support groundbreaking approaches to HIV prevention and treatmentWith diverse proposals focused on everything from natural killer cells to therapeutic vaccines to treat HIV, three recipients have been selected for the 2018 Avant-Garde
Sawyer Lab, BioFrontiers Institute, University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder researchers studying the emergence of viruses from wildlife populations provide a key clue to how simian immunodeficiency virus emerged from monkeys,
ÌýFor billions of years, the battle between cells and viruses has been a primary driver of evolution. University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder researcher Dr. Sara Sawyer has dedicated her career to this relationship, combining methods from virology and
Just as flu season swings into full gear, researchers from the University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder and University of Texas at Austin have uncovered a previously unknown mechanism by which the human immune system tries to battle the influenza A virus. The
