Scientists have finally watched influenza viruses break into living human cells in real time, catching the microscopic invaders as they latch on, glide across the surface and slip inside. Instead of a ...

The flu virus attacks much like a thief looking for unlocked doors. Its HA and NA proteins grab onto tiny molecules called sialic acids on the surface of cells. Once attached, the virus slides along ...

When a pathogen like a dangerous virus invades the human body, it usually has to enter human cells to cause an illness. Influenza has to latch onto a receptor on the surface of a human cell so it can ...

Like these substances, influenza viruses must also attach to molecules on the cell surface. The dynamics are like surfing on the surface of the cell: the virus scans the surface, attaching to a ...

More than 200,000 children succumb to viral gastroenteritis infections, or stomach flu, all over the world every year. 1 Human astroviruses are a common cause of such infections, leading to diarrhea, ...

At the surface, the immune response to a flu virus is simple. Some cells recognize the pathogen and send a signal to the immune system, and immune cells produce a potentially lifesaving antibody ...

Scientists have captured a never-before-seen, high-resolution look at influenza’s stealthy invasion of human cells, revealing that the cells aren’t just helpless victims. Using a groundbreaking ...
