Kyoto, Japan -- Six years before the start of the COVID-19 pandemic, an Ebola outbreak in West Africa had people fearing the possibility of a global outbreak. This was the first time many had ever heard of the virus, but since it was first identified in 1976, there have actually been more than 20 serious Ebola incidents. Thankfully, none of them had the global reach of the coronavirus.
Ebola has not been eradicated, however. This deadly virus, which causes severe hemorrhagic fever in humans and has a fatality rate of about 50%, is still at large and could thus still cause a major outbreak, unless further research finds an effective solution.
A major challenge lies in the virus' structure and regulatory mechanisms, which have remained largely unclear. In particular, scientists have long struggled to fully understand its nucleocapsid, the protein shell that plays an important role in genome replication and transcription.
Researchers at the University of Cologne have discovered that mRNA-based COVID-19 vaccines have a persistent effect on the innate immune system. These mechanisms may help the human body to better protect itself against potential future infections / publication in ‘Molecular Systems Biology’
The global average for countries to report genetic information about bird flu, crucial to tracking and preventing a human pandemic, was seven months, and Canada came in last, a new study has found.
Authors of the non-peer reviewed commentary published today in Nature Biotechnology say the work highlights the urgent need for Canada and other countries to speed up the pipeline from sampling an infected creature, analysis of the genetic information, and submission to a global scientific database.
Dr. Sarah Otto (SO), professor in the department of zoology, and Sean Edgerton (SE) (he/him), zoology doctoral student, discuss why getting this information quickly is crucial, and how Canada has pulled its socks up once beforeEarly animal studies show that a single vaccine could protect the recipient from different variants of the coronaviruses that cause COVID-19, the flu and the common cold. In addition to creating antibodies that target a specific region of the spike protein that doesn’t mutate, the vaccine removes the sugar coat from the virus that allows it to hide in the body. The researcher will present his results at the ACS Spring 2025 Digital Meeting.
An immune system defect makes affected individuals vulnerable to severe viral diseases such as influenza or COVID-19. It is caused by the body's own antibodies, which inhibit important defense proteins known as type I interferons. UZH researchers have now generated “decoy molecules” that intercept these autoantibodies and restore the immune defense – the foundation for a possible new therapy.
When wildfires threaten communities, human health can be impacted as smoke distributes on the breeze, infiltrating various structures. To help people protect themselves and their families, researchers have developed a low-cost, durable, do-it-yourself air filtration system that works as well as more expensive HEPA filters to clear indoor air pollutants such as smoke — or possibly limit the impact of airborne disease spread. They will present their results at the ACS Spring 2025 Digital Meeting.
A study by A*STAR Infectious Diseases Labs (A*STAR IDL) and A*STAR Institute of High Performance Computing (A*STAR IHPC) has assessed the airborne transmission risk of mpox compared to SARS-CoV-2 and smallpox. Using computational modelling and virological data, researchers found that mpox is significantly less likely to spread via respiratory aerosols in its current form. However, potential viral evolution underscores the need for continued surveillance. The study, published in The Lancet Microbe, highlights the value of interdisciplinary research in understanding infectious disease transmission.
Ashraf Ibrahim, PhD, an investigator at The Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center for more than 33 years, and Assistant Research Scientist, Yiyou Gu, PhD, at TLI for more than eight years, have been conducting research using monoclonal antibodies to address mucormycosis, a fungal infection caused by Mucorales, has high mortality rates in people with weakened immune systems and those suffering from severe trauma like burns, blast injuries or victims of natural disasters. The disease caused serious infection among COVID-19 patients treated with high doses of corticosteroids with mortality rates close to 60 percent. In the United States, there are approximately 4,000 cases per year with a rate of 200,000 in Southeast Asia where the disease is endemic to India. While vaccines and immunotherapies are available for viruses and bacteria, effective antifungal immunotherapies for mucormycosis, specifically, are lacking.
