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 ...

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 flu illness is triggered by influenza viruses, which enter the body through droplets and then infect cells. Researchers from Switzerland and Japan have now investigated the flu virus in minute ...

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 ...

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 ...

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 ...

H5N1 avian influenza is highly pathogenic and has been devastating bird populations worldwide. It continues to do so, and is also moving into new animals, like skunks, bears, raccoons, cats, and dairy ...

How flu viruses enter cells has been directly observed thanks to a new microscopy technique with the potential to revolutionize research on membrane biology, virus–host interactions and drug discovery ...

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 ...

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 ...
