Antibodies and SARS-CoV-2 infections: Tthe more the better
Oxford University Hospital tracked infections in 12,500 of its healthcare workers. Enlarge / Oxford University is associated with the hospital that ran this study, as well as a vaccine that is currently undergoing clinical trials. (credit: Gallo.....»»
Study reveals how our immune system reacts to COVID-19 variants
New research into how our immune system responds to COVID-19 reveals that those infected by early variants in 2020 produced sustained antibodies, but these antibodies are not as effective against contemporary variants of the virus......»»
"Fortunate accident" may yield immunity weapon against antibiotic-resistant bacteria
Researchers have announced an accidentally discovered, potentially game-changing treatment -- one that may one day provide an alternative immune-based solution to the danger of antibiotic-resistant bacterial infections......»»
New study shows mathematical models helped reduce the spread of COVID-19
Researchers have published new findings that take a first look at the use of SARS-CoV-2 mathematical modeling to inform early statewide policies enacted to reduce the spread of the coronavirus pandemic in Colorado. Among other findings, the authors e.....»»
Stem cells can use same method as plants and insects to protect against viruses
Researchers at the Francis Crick Institute have found a vital mechanism, previously thought to have disappeared as mammals evolved, that helps protect mammalian stem cells from RNA viruses such as SARS-CoV-2 and Zika virus. The scientists suggest thi.....»»
Study shows laboratory developed protein spikes consistent with COVID-19 virus
A new study has found that the key properties of the spikes of SARS-CoV-2 virus which causes COVID-19 are consistent with those of several laboratory-developed protein spikes, designed to mimic the infectious virus. The findings show how that viral s.....»»
Researchers find potential path to a broadly protective COVID-19 vaccine using T cells
Using a method developed for HIV, researchers have identified stable T cell vaccine targets in SARS-CoV-2. These stable targets, known as highly networked epitopes, are highly likely to be stable in different variants of the virus. The results provid.....»»
Study shows laboratory-developed protein spikes consistent with COVID-19 virus
A new international study has found that the key properties of the spikes of SARS-CoV-2 virus which causes COVID-19 are consistent with those of several laboratory-developed protein spikes, designed to mimic the infectious virus......»»
Ten talismans for a new understanding of cities in post-pandemic times
For more than a year and a half, the SARS-CoV-2 pandemic has kept the world locked down. Schools, universities, cafés and restaurants, cultural institutions and stores have been closed for long stretches of 2020 and 2021. In many parts of the world,.....»»
Medical startup iXensor launches smart antigen testing solution for COVID-19
Taiwan-based medical technology startup iXensor has launched a smart antigen testing solution that is able to detect COVID-19 infections and can show the rest results via its smartphone app......»»
Fibromyalgia likely the result of autoimmune problems
New research has shown that many of the symptoms in fibromyalgia syndrome (FMS) are caused by antibodies that increase the activity of pain-sensing nerves throughout the body. The results show that fibromyalgia is a disease of the immune system, rath.....»»
Study with healthcare workers supports that immunity to SARS-CoV-2 is long-lasting
One year after infection by SARS-CoV-2, most people maintain anti-spike antibodies regardless of the severity of their symptoms, according to a study with healthcare workers. The results suggest that vaccine-generated immunity will also be long-lasti.....»»
SARS-CoV-2 replication targets nasal ciliated cells early in COVID-19 infection
The establishment of nasal mucosal immunity against SARS-CoV-2 through a nasal vaccine could be the most efficient way to combat COVID-19 infection......»»
COVID-19 aggravates antibiotic misuse in India, study finds
Antibiotic sales soared during India's first surge of COVID-19, suggesting that the drugs were inappropriately used to treat mild and moderate COVID-19 infections, according to new research. The excessive usage is especially concerning because antibi.....»»
Moderna and Pfizer-BioNTech vaccines prime T cells to fight SARS-CoV-2 variants, study finds
Researchers have found that T cells from people who have recovered from COVID-19 or received the Moderna or Pfizer-BioNTech vaccines are still able to recognize several concerning SARS-CoV-2 variants......»»
Antibodies help identify women protected from placental malaria
Six antibody characteristics could help scientists identify which pregnant women are at risk of placental malaria infections......»»
Study reveals mechanisms of increased infectivity, antibody resistance of SARS-CoV-2 variants
Combining structural biology and computation, researchers have identified how multiple mutations on the SARS-CoV-2 spike protein independently create variants that are more transmissible and potentially resistant to antibodies......»»
New technique to treat middle ear infections
In a new study, researchers have designed a miniaturized 3D-printed device to inactivate Pseudomonas aeruginosa, a common bacterium that causes the infection......»»
Researchers discover unique "spider web" mechanism that traps, kills viruses
Immunologists have discovered a previously unknown mechanism which acts like a spider web, trapping and killing pathogens such as influenza or SARS-CoV-2, the virus responsible for COVID-19......»»
COVID-19: Reduced sense of taste and smell lingers
Patients with mild COVID-19 infections experience a significantly increased longer lasting reduced sense of taste and smell. This is also the case for long-term shortness of breath, although relatively few people are affected. And women and the elder.....»»
Antibiotic-resistant bacteria found in cattle, but new technology can help with detection
Growing resistance to our go-to antibiotics is one of the biggest threats the world faces. As common bacteria like strep and salmonella become resistant to medications, what used to be easily treatable infections can now pose difficult medical challe.....»»
