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.
Investigators involved in a multicenter study co-led by Cedars-Sinai discovered a pathway by which immune cells prevent the lungs' protective barrier from healing after viral infections like COVID-19.
A recent study by the Cusack group clarifies how a crucial enzyme of the avian influenza virus can change, enabling the virus to spread to mammals.
A viral spillover of the highly pathogenic avian influenza virus belonging to the hemagglutinin 5 neuraminidase 1 (H5N1) 2.3.4.4b clade among herds of dairy cattle.
Scientists at La Jolla Institute for Immunology (LJI) have published the first-ever, in-depth analysis of immune cell memory in the upper airways of adult volunteers. Among these immune cells, the researcher spotted "tissue resident" memory cells, which stand ready to defend the airway from SARS-CoV-2 and other respiratory diseases.
A new study reveals evidence that avian influenza has spilled over from birds to dairy cattle across several U.S. states, resulting in mammal-to-mammal transmission between cows and from cows to cats and a raccoon.
The majority of influenza viruses enter animal or human cells through particular surface-based pathways. It has recently been found by researchers at the University of Zurich that some influenza viruses, both human and avian, can also enter cells through a second entry point that involves an immune system protein complex.
Researchers recently discovered that auto-antibodies against their type 1 interferons, crucial immunological signaling proteins, were present in some COVID-19 patients.
The highly virulent H5N1 avian influenza was initially found in dairy cattle in the United States in March, and by May, outbreaks had been reported from nine states. The research was published in the journal Nature Communications.
Scientists at UC Riverside have demonstrated a new, RNA-based vaccine strategy that is effective against any strain of a virus and can be used safely even by babies or the immunocompromised.
By focusing on a poxvirus protein, a team led by UT Southwestern Medical Center scientists has discovered an antiviral immune pathway that broadly fights a wide variety of viruses.
The highly pathogenic avian influenza virus H5N1 has adapted to spread between birds and marine mammals, posing an immediate threat to wildlife conservation, according to a study from the University of California, Davis, and the National Institute of Agricultural Technology (INTA) in Argentina.
Using a virus-like delivery particle made from DNA, researchers from MIT and the Ragon Institute of MGH, MIT, and Harvard have created a vaccine that can induce a strong antibody response against SARS-CoV-2.
The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections, according to researchers from the Center for Translational Antiviral Research in the Institute for Biomedical Sciences at Georgia State University.
Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical?
The body's immune response to Epstein-Barr virus (EBV) may play a role in causing damage in people with multiple sclerosis, according to a new study led by UTHealth Houston.
Scientists at La Jolla Institute for Immunology (LJI) are investigating a talented type of T cell.
T cells are soldiers on the front lines of the human immune system. They are responsible for many important roles, including attacking viral- or bacterial-infected cells and certain cancer cells, and immunological memory – remembering the specific pathogens or the cancer signatures that originally trigger T cells.
The genome of the SARS-CoV-2 virus encodes 29 proteins, one of which is an ion channel called E. This channel, which transports protons and calcium ions, induces infected cells to launch an inflammatory response that damages tissues and contributes to the symptoms of Covid-19.
Scientists have used gene editing techniques to identify and change parts of chicken DNA that could limit the spread of the bird flu virus in the animals.
Researchers from University of British Columbia and Michigan State University have invented a system that can quickly and inexpensively detect airborne viruses using the same technology that enables high-speed trains.
