Surprisingly, the flu vaccine from last year kept protecting people even as a new version of the H3N2 virus started spreading. Public health experts had worried the shot wouldn’t fight off these slightly changed viruses. But in adults, the protection stayed strong, according to new findings. This is
The flu, caused by the Influenza A virus, is notorious for its ability to spread and infect. This virus does not just stop at the lungs. It can lead to a serious condition called viral sepsis (VS). This condition can be deadly. It causes problems in the lungs and other organs. However, the exact way
The world of viruses is complex, and the flu is no exception. The way influenza viruses behave can vary greatly depending on their genetic makeup and the type of cells they target. This variability has been a subject of many studies, including those focusing on different subtypes of influenza A an
Influenza A virus, or IAV, has a sneaky trick up its sleeve. It's a tiny piece of RNA, called USP30-AS1. This RNA is part of our own genetic material, but the virus hijacks it to help itself multiply. The story begins with a pathway in our cells called JAK-STAT. When IAV invades, this pathway kicks
The influenza A virus is a persistent threat to public health, causing yearly outbreaks and occasionally, global pandemics. The usual countermeasures, vaccines and antiviral drugs, have limitations. One issue is that new virus strains can resist antivirals and make vaccines less effective. Tradition
Ever wondered how we can combat viruses like COVID-19 and influenza A in the air? Scientists explored the power of three chemicals – hypochlorous acid, chlorine dioxide, and ozone – to inactivate these viruses. They created a 1 cubic meter chamber and filled it with a mix of these viruses in saliva.
Scientists were intrigued by six unique nitrogen-containing compounds found in Sarcodon imbricatus mushrooms. These compounds, including two types of amino acids and four heterocyclic compounds, were examined for their antiviral properties. One standout, Compound 2, a specific type of (S)-2-(hydroxy
Ever wondered if starting treatment early for the flu can make a big difference? Let's dive into the world of early oseltamivir therapy. This drug, often called by its brand name Tamiflu, has been shown to help adults who are hospitalized with influenza A. But why is early treatment so important? I
Influenza A is giving scientists a run for their money with its drug-resistant variant, the S31N M2 proton channel. Lately, researchers have been concerned about how different lipid environments might affect this channel's structure. The M2 tetramer's native shape is still a hot topic among experts.
