The process by which phages—viruses that infect and replicate within bacteria—enter cells has been studied for over 50 years. In a new study, researchers from the University of Illinois Urbana ...

Then, the virus must evade the host’s immediate defenses, which includes physical barriers, such as layers of skin and mucosa, as well as immune cells that detect and attack invading microbes. Once in ...

The target: a spikey protein that covers the new coronavirus. That protein lets the virus invade human cells. If the body's immune system recognizes the spike and blocks it, people won't get infected.

A mouse study at Memorial Sloan Kettering Cancer Center has found that adding Nef, a protein from HIV, allows donor CAR T cells to avoid detection by the immune system while still attacking tumors.

Protein complex in bacterial cell membrane acts like a rotary motor to recruit DNA-degrading enzymes to defend against phage ...

"We thought that these viruses, which have been invading cells for millennia, would have something to teach us about avoiding immune detection and keeping the cells that they invade alive." ...

New research explores the cellular fight for iron during COVID-19 infection, unraveling the body's defense mechanisms and the ...

Scientists at the University of São Paulo analyzed blood samples donated by six serodiscordant couples where female partners were resistant to SARS-CoV-2 despite intense contact with their infected ...

Since early 2024, the U.S. has logged 66 human cases of H5N1. Scientists are keeping a watchful eye on the virus’s spread as we enter a new year.

“We wanted to learn which components of the immune system might cause rejection of donor CAR T cells, and how different viral proteins could figure out a way around that,” Dr. Perica says. “We thought ...
