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 ...

Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a ...

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 ...

For the first time, scientists have been able to watch the flu virus live as it infects human airway cells. They developed a ...

Influenza viruses are among the most likely triggers of future pandemics. A research team from the Helmholtz Center for Infection Research (HZI) and the Medical Center—University of Freiburg has ...

The influenza virus manipulates the body's gene regulation system to accelerate its own spread. A new study also shows that an already approved drug could help strengthen immune defenses -- though its ...

New study reveals how influenza virus infiltrates heart tissue via specialised immune cells, triggering damaging interferon ...

Cells actively help to capture and incorporate influenza viruses. Here, a cell is shown, with a virus in the centre of the image. Fever, aching limbs and a runny nose – as winter returns, so too does ...

VIVIAN, LA - DECEMBER 12: With a temperature of 103.8, Asa Moore, 6, of Vivian, Louisiana is examined by John Messier, a physician's assistant, at the North Caddo Surgical and Medical Center for ...

Influenza A virus particles strategically adapt their shape—to become either spheres or larger filaments—to favor their ability to infect cells depending on environmental conditions, according to a ...

Viruses have no metabolism of their own and must therefore infect host cells in order to replicate. Contact between the virus and the cell surface is a crucial first step, which can also prevent ...
