They kill half a million people worldwide every year. These viruses can also wreak havoc on animals, as in the case of avian flu. A team has now identified how the influenza A virus manages to penetrate cells to infect them. By attaching itself to a receptor on the cell surface, it hijacks the iron transport mechanism to start its infection cycle. By blocking the receptor involved, the researchers were also able to significantly reduce its ability to invade cells. These results highlight a vulnerability that could be exploited to combat the virus.

Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.

Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.

But now a highly infectious virus may put that hard-fought comeback in jeopardy. New research showed highly pathogenic avian influenza, also known as H5N1, is killing off unprecedented numbers of mating pairs of bald eagles.

Migratory wild birds could be to blame for transmitting the virus to commercial flocks, but no one has looked closely at this wandering population until now. Researchers now report that cooler temperatures and certain species gathering in the same winter habitat could increase the circulation of H7 and H9 strains.

This opens the way to potential new treatments that can save many lives. Tue, 17 May 2022 15:18:20 EDT //www.koonmotors.com/releases/2022/05/220517151820.htm //www.koonmotors.com/releases/2022/05/220511142354.htm Researchers have shown for the first time in mice that heart problems associated with the flu are not caused by raging inflammation in the lungs, as has long been predicted. Instead, the electrical malfunctions and heart scarring seen in some of the sickest flu patients are caused by direct influenza infection of cardiac cells.

So concludes a study from scientists at multiple institutions. Loss and degradation of natural habitats and direct overexploitation of many species are cited as the key threats to avian biodiversity. Climate change is identified as an emerging driver of bird population declines.

This allowed them to prove that a single shot immunization containing M2e was able to trigger long-lasting immune responses that could protect effectively against multiple strains of the flu. The team was also able to demonstrate that this vaccination approach significantly enhanced protective immune responses in the context of pre-existing flu immunity. This scenario is particularly relevant in adult and elderly populations, where individuals have been exposed to flu viruses multiple times in the past and have low levels of M2e-specific antibodies in their blood circulation.

Their approach involves packing mRNA inside nanoparticles that mimic the flu virus -- a naturally efficient vehicle for delivering genetic material such as RNA inside cells.

Using influenza as a model, researchers have developed a new technique that overcomes many of these roadblocks, and they say the tool may be useful for better assessments of exposure to a variety of viruses, including the ones that cause COVID-19 and pneumonia.

The study found that not only are traditional flu-related outcomes worse among some patients with CVD, but infection in those patients also is associated with an increased risk of cardiovascular events. Getting the influenza vaccine, however, substantially reduces cardiovascular risks.

New research explores the role of nasal bacteria and provides clues to developing better intranasal vaccines for flu and COVID-19.

According to the researchers, the vast majority of the extinct species shared several features: they were large, they lived on islands, and many of them were flightless.

This insight comes 30 years after discovery of that surface protein, called pneumococcal surface protein A. This mechanism had been missed in the past because it facilitates bacterial adherence only to dying lung epithelial cells, not to living cells.

The vaccine has the potential to improve the effectiveness of seasonal flu vaccines, accelerate vaccine production timelines and increase vaccine supplies because of its small dosage.

The model can predict which sections of viral surface proteins, including those of influenza, HIV, and SARS-CoV-2, are more likely to mutate in a way that allows the virus to evade the human immune system. It can also identify sections that are less likely to mutate, making them good targets for new vaccines.

All across Europe, the individual enjoyment of life correlates with the number of surrounding bird species. An additional 10% of bird species therefore increases the Europeans' life satisfaction as much as a comparable increase in income. Nature conservation thus constitutes an investment in human well-being.

Rhinovirus, the most frequent cause of common colds, can prevent the flu virus from infecting airways by jumpstarting the body's antiviral defenses, researchers report.

A team of researchers has developed an approach to assess whether a vaccine activates the kind of immune cells needed for long-lasting immunity against new influenza strains. The findings could aid efforts to design an improved flu vaccine.

That's the result of a study in nearly 3 million Americans. One out of five individuals will develop heart failure in their lifetime. An estimated 26 million people are affected worldwide.

But this is not the case according to a new study.
