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 ...

Our immune systems rely on iron to function, but so do invading viruses and bacteria. New research from Binghamton University ...

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.

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 ...

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

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

Researchers have identified a novel genetic risk factor for SARS-CoV-2 infection, providing new insights into the virus's ability to invade human cells. SARS-CoV-2 is the virus that spreads COVID-19.

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.

CAR T cell therapy is one of the most promising new cancer treatments to emerge in recent years. It involves removing a patient's own immune T cells and engineering them to recognize specific targets ...

Under normal temperature conditions, these cells—which in vivo occur near the front of the nose and therefore are among the first encountered by an invading virus—respond to viruses by triggering the ...
