By comparing the neutralisation capacity induced by the different variants of SARS-CoV-2, a team from Geneva reveals the exceptional capacity of Omicron to evade our immunity.
To develop new drugs, detailed knowledge about nature’s smallest biological building blocks is required. A new microscopy technique that allows proteins, DNA and other tiny biological particles to be studied in their natural state.
Scientists shared one of the first high-resolution looks at the rabies virus glycoprotein in its vulnerable 'trimeric' form, revealing potential vaccine targets.
Latest developments in computational protein design enable the simulation of sequence and structural changes in proteins for creating novel agents in human medicine.
In patients with serious and long-term Covid-19, disturbed blood coagulation is often observed. Now, Swedish researchers found a connection between harmful amyloid production and Covid-19 symptoms.
Scientists at the La Jolla Institute for Immunology discover new drug target for severe asthma and fibrosis.
Noninvasive sound technology breaks down liver tumors in rats, kills cancer cells and spurs the immune system to prevent further spread.
A chip-based infection model developed by Jena researchers enables live microscopic observation of damage to lung tissue caused by the invasive fungal infection aspergillosis.
A platform for studying how the human immune system responds to hepatitis C infection by combining microfluidic technology with liver organoids could speed the hunt for a vaccine.
A new biodegradable gel improves the immune system’s ability to keep cancer at bay after tumors are surgically removed.
An anti-inflammatory drug incorporated into the coating around an implantable electronic medical device – such as a pacemaker – can reduce the body’s "foreign body" reaction.
New research from the University of East Anglia (UEA) and Quadram Institute reveals how our immune system can be triggered to attack cancer cells.
Researchers from Charité – Universitätsmedizin Berlin and Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE) present new findings on the immune response against SARS-CoV-2.
A new study shows that the SARS-CoV-2 Omicron variant is less effective than Delta at blocking a cellular defence mechanism against viruses, the so-called 'interferon response'.
How long can Covid-19 antigen tests reliably tell the antibody status? Researchers at the Paul-Ehrlich-Institut identified several factors that affect the detection duration.
The Omicron variant of SARS-CoV-2 may be significantly better at evading vaccine-induced antibodies – but preliminary evidence suggests it is less likely to cause severe illness in the lungs.
Autoimmune hepatitis (AIH) is a chronic liver inflammation that is triggered by an immunological malfunction. In this case, the immune system falsely recognises the patient's own liver cells as "foreign to the body". The symptoms of this rare liver disease are unspecific, and the exact cause is not yet known. If left untreated, AIH can lead to abnormal scarring (fibrosis) of the liver,…
Hope for a future without fear of Covid-19 comes down to circulating antibodies and memory B cells. Unlike circulating antibodies, which peak soon after vaccination or infection only to fade a few months later, memory B cells can stick around to prevent severe disease for decades. And they evolve over time, learning to produce successively more potent “memory antibodies” that are better at…
After infection with SARS-CoV-2, where does the immune system store the memory to provide long-term protection against reinfection? Though numerous studies have examined blood to track immune responses to SARS-CoV-2, a new study of Covid survivors shows that the memory of the infection is primarily stored in T and B cells within the lung and the lymph nodes surrounding the lung.
After a liver transplant, patients have to take immune-suppressing drugs for the rest of their lives. These so-called immunosuppressants prevent the organ from being rejected. However, the drugs increase the risk of cancer and serious infections. They can also significantly impair kidney function and even lead to dialysis. In order to be able to give those affected as much immunosuppression as…
Hokkaido University scientists and colleagues in Japan have found a way that could help some patients overcome resistance to an immunotherapy treatment for cancer. The approach, proven in mice experiments, was reported in the Journal for Immunotherapy of Cancer.
Hospitalized Covid-19 patients are substantially more likely to harbor autoantibodies — antibodies directed at their own tissues or at substances their immune cells secrete into the blood — than people without Covid-19, according to a new study.
Extremely premature infants are at a high risk for brain damage. Researchers at the University of Vienna and the Medical University of Vienna have now found possible targets for the early treatment of such damage outside the brain: Bacteria in the gut of premature infants may play a key role.
The World Health Organization (WHO) has taken a closer look at coronavirus variant B.1.621. The strain, first encountered in January 2021 in Colombia, shows traits that could enable the virus to circumvent immune response to vaccination. As a result, the variant, named "Mu", has been classified as "Variant of Interest" (VOI). Despite its prominence in Colombian new infection,…
A novel CT scan-based approach has revealed significant changes in a parameter indicating lung destruction in some asthmatics. This finding could lead to more personalized treatments for asthma accompanied by persistent airflow limitation. Clinicians have long thought that some people with asthma experience declines in their lung function, called fixed airflow obstruction (FAO), due to changes to…
