Influenza (the flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year. Every year in the United States, on average 5% to 20% of the population gets the flu; more than 200,000 people are hospitalized from flu complications, and; about 36,000 people die from flu-related causes. Some people, such as older people, young children, and people with certain health conditions, are at high risk for serious flu complications.
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS‑CoV‑2 can slip past vaccines and antibody drugs before scientists fully understand what has changed.
A research team comprising Associate Professor FUNAKOSHI Yohei, Associate Professor YAKUSHIJIN Kimikazu, Professor MINAMI Hironobu, and Associate Professor OHJI Goh of Kobe University, together with graduate student MASUDA Genki, then-graduate student IIZUMI Shunsuke, Associate Professor OHUE Masahito, and colleagues at the Institute of Science Tokyo, has developed a new analysis method, LM-QASAS.
Bats are anomalies in the mammalian world-they fly, have long lifespans, and rarely get cancer. Scientists now suspect the bat immune system enables them to live longer without disease, according to a new study published today in Nature.
A new study identifies influenza A virus interactions with human proteins, uncovering mechanisms of paraspeckle disruption and insights for antiviral development.
The amino acid arginine helps to keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes.
To prevent viruses from sickening or killing us - whether it's an individual case of hepatitis B or a COVID pandemic - it's crucial to understand how the proteins they make initiate changes in our bodies that allow them to flourish.
Trans-vaccenic acid (TVA), the most abundant trans fatty acid found in human breast milk, helps boost immune system development and has long-lasting effects on immune system health in mice, according to a new study by researchers from the University of Chicago.

A new study tracking thousands of B cells across more than 100 germinal centers in mice reveals how the system consistently produces highly effective antibodies.
T cells are among the immune system’s essential soldiers. They can inhibit tumor development and even combat serious infections.
In a new study published in Nature Immunology, researchers at Boston Children's Hospital demonstrated that pairing the original COVID-19 mRNA vaccine with an immune system enhancer, known as an adjuvant, extended the duration of the vaccine's protection in mice from a few months up to two years. The combo also showed a more pronounced response against omicron viral components than the vaccine alone.
Engineers from the University of Houston, MIT and Harvard have developed a new mRNA-based strategy that dramatically amplifies the T-cell response to vaccines - an advance that could lead to far more powerful cancer vaccines and stronger protection against infectious diseases.
As part of the body's first line of defense against foreign invaders, macrophages play an integral role in the innate immune system.
During the early stages of a pandemic, viruses tend to evolve in ways that enhance their ability to reproduce and spread, rather than to evade the host's immune system.
The influenza D virus that researchers say has been flying under the radar since its detection in animals in 2011 can vigorously make copies of itself in human cells and lung tissue samples, a new study shows.
An innovative gene-editing strategy could establish a new way for the body to manufacture therapeutic proteins-including certain kinds of highly potent antibodies the are naturally difficult to produce-by reprogramming the immune system itself.
The wave-shaped chart Ratul Chowdhury pulls up on a computer monitor in his office captures the evolutionary cat-and-mouse game his research lab is up against.
Viruses are masters at entering human cells, thanks to specialized proteins that coat their surfaces.
According to a study published by investigators at Georgia State University’s Institute for Biomedical Sciences, a novel vaccine platform has been created to generate broad, protective immunity against multiple influenza virus infections, demonstrating potential as an effective mucosal vaccination approach.
Scientists at the University of Wisconsin School of Veterinary Medicine have identified a potential approach to develop longer-lasting vaccines for respiratory viruses such as influenza and the coronavirus that causes COVID-19.
