COLUMBUS, Ohio – Researchers have identified new roles for a protein long known to protect against severe flu infection – among them, raising the minimum number of viral particles needed to cause ...

Infectious microbes have evolved sophisticated means to invade host cells, outwit the body’s defenses and cause disease. While researchers have tried to puzzle out the complicated interactions between ...

Some pathogens hide inside human cells to enhance their survival. Researchers have uncovered a unique tactic certain bacteria use to spread in the body without being detected by the immune system. In ...

To cause an infection, pathogens have to get into our cells. So how do they do it? A new study has used lung organoids, which are small, simplified versions of human lungs, to learn more about the ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.
