Retroviruses -- the family of viruses that includes HIV -- are almost half a billion years old, according to new research. That's several hundred million years older than previously thought and ...

Retroviruses include HIV and other viruses that cause disease in many different vertebrate species. Most retrovirus research has focused on mammals and birds, but retroviruses also infect many other ...

From innovative therapies to global care strategies, HIV experts at CROI 2026 share the breakthroughs and lessons they hope ...

Retroviruses probably evolved roughly half a billion years ago, making this medically and economically important group of viruses five times older than scientists previously thought. The finding, ...

Vaccine development remains central to reducing incident HIV globally, particularly where long-acting PrEP access is limited, with therapeutic and preventive approaches advancing in parallel.

A cluster of antiviral genes in humans has likely battled retroviral invasions for millions of years. New research now finds that in addition to the previously identified TRIM5 gene that can defend ...

Bats have long been known as important hosts of zoonotic viral pathogens. Zoonotic viruses that bats transmit are capable of infecting humans and have caused devastating infections throughout the ...

Scientists from the University of Colorado, Boulder (CU Boulder), have published new research in Science Advances that shows that endogenous retroviruses (ERVs)—“junk DNA”—in the genome can play a ...

Researchers report February 15 in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic ...

Retroviruses probably evolved roughly half a billion years ago, making this medically and economically important group of viruses five times older than scientists previously thought. “These viruses ...
