  • NHLBI Researchers Discover Never-Before-Seen Mode of Viral Transmission
    National Heart, Lung, and Blood Institute (NHLBI)-funded researchers have discovered a novel means by which viruses spread between cells: multiple polioviruses, a type of enterovirus, travel together within a membrane-enclosed sac, arriving together at a cell they then ...More

  • Viruses Play Important Role in Building Up the Complex Networks That Characterize the Human Brain
    A new study from Lund University in Sweden indicates that inherited viruses that are millions of years old play an important role in building up the complex networks that characterize the human brain. Researchers have long been aware that endogenous retroviruses constitute ...More

  • Scientists Identify New and Beneficial Function of Endogenous Retroviruses in Immune Response
    Retroviruses are best known for causing contagious scourges such as AIDS, or more sporadically, cancer. But researchers at UT Southwestern Medical Center and Karolinska Institutet in Stockholm, Sweden, found that endogenous retroviruses (ERV) also play a critical role in ...More

  • Herpes Virus Rearranges Telomeres to Improve Viral Replication
    A team of scientists, led by researchers at The Wistar Institute, has found that an infection with herpes simplex virus 1 (HSV-1) causes rearrangements in telomeres, small stretches of DNA that serve as protective ends to chromosomes. The findings, which will be published ...More
