As highly pathogenic avian influenza has spread in dairy herds across the U.S., the virus is being detected in raw milk. A new study by a broad team of researchers at Iowa State University's ...

"Human influenza A viruses of subtype H2N2 and related H2N2 avian influenza viruses can enter cells through a second receptor. They use an alternative entry pathway," says Stertz.

With the help of their new development, they have also analyzed how novel influenza viruses use alternative receptors to enter target cells. Share: Facebook Twitter Pinterest LinkedIN Email.

What they found – loads of the H5N1 influenza virus ... Their findings, published as a preprint study, show that cows have the same receptors for flu viruses as humans and birds.

Microscope images of mammary gland tissue taken from a dairy cow infected with highly pathogenic avian influenza are magnified by 200 times on the left and 400 times on the right. On the left, cells ...

Scientists have discovered that H5N1, the strain of highly pathogenic avian influenza virus currently spreading in U.S. dairy cows, only needs a single mutation to readily latch on to human cells ...

This work is published in Science in the paper, “A single mutation in bovine influenza H5N1 hemagglutinin switches specificity to human receptors.. Influenza viruses attach to cells using ...

“Human influenza A viruses of subtype H2N2 and related H2N2 avian influenza viruses can enter cells through a second receptor. They use an alternative entry pathway,” says Stertz.

Avian influenza A viruses, particularly the H5N1 subtype, ... Humans: SA receptors are deep in the lungs, making human infection rare but more severe because of where the virus replicates.

Human influenza viruses, on the other hand, prefer the shape of a receptor that lines our upper respiratory tracts. advertisement The new work, published in Nature , showed that the bovine H5N1 ...

Hemagglutinin—the “H” in “H5N1”—is a protein that helps influenza viruses bind to host cells; the hemagglutinin achieves this by recognizing receptors that line those cells.
