Could the intranasal route be an alternate avenue of COVID-19 vaccination?

A new study has been published in the journal Vaccines that summarizes the history of vaccines, reviews the current progress in COVID-19 vaccine technology, and discusses the status of intranasal COVID-19 vaccines as a potential pathway to immunization.

Immunomodulatory therapies for nephrological autoimmune diseases may help treat severe COVID-19

Various viruses and bacteria have long been known to cause autoimmune diseases where there is such a predisposition. This phenomenon also seems to play a major role in SARS-CoV-2, especially in severe courses.

NIH researchers identify novel small molecule inhibitors of SARS-CoV-2 variants

A team of scientists from the National Institutes of Health (NIH), USA, has recently identified six novel small molecule inhibitors of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants. The study is currently available on the bioRxiv* preprint server.

Bacteria causing urinary tract infections can originate in meat-production chain

In young women, Staphylococcus saprophyticus is a main cause of urinary tract infections (UTI), reaching 20% prevalence. Understanding the epidemiology of this microorganism can help identify its origin, distribution, causes, and risk factors.

Scientists explain why space travel weakens the human immune system

Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their mission.

Study shows how cowpea mosaic plant virus stimulates the immune system against cancer

Previous work by a team of researchers led by Steven N. Fiering, PhD, Immunology and Cancer Immunotherapy researcher at Dartmouth's and Dartmouth-Hitchcock's Norris Cotton Cancer Center and Nicole Steinmetz, PhD, Jacobs School of Engineering and Moores Cancer Center, University of California San Diego, showed that a plant virus that does not infect mammals, cowpea mosaic plant virus (CPMV), when injected into cancerous tumors, strongly stimulated the immune system to attack and often eliminate the tumor.

Restoring gut microbes can improve antibiotic-induced dysbiosis and prevent colitis in mice

A new study at the University of Chicago has determined that restoring a single microbial species -- Bacteroides sp. CL1-UC (Bc) -- to the gut microbiome at a key developmental timepoint can prevent antibiotic-induced colitis in a mouse model of the condition.

Novel method allows rapid, absolute quantification of viral nucleic acids

Researchers from Critical Analytics for Manufacturing Personalized-Medicine, an Interdisciplinary Research Group at the Singapore-MIT Alliance for Research and Technology, MIT's research enterprise in Singapore, have developed a new method for rapid and accurate detection of viral nucleic acids - a breakthrough that can be easily adapted to detect different DNA/RNA targets in viruses like the coronavirus.

Study observes broad and invariable memory B cell response following SARS-CoV-2 infection

A new study by researchers at the Oregon Health & Science University (OHSU) in the USA goes far in answering this question by showing the presence of memory B cells that react to the original SARS-CoV-2 as well as VOCs.

Study offers overview of SARS-CoV-2 infection in children

A new study by researchers in the USA summarizes what is known about the prevalence of the infection, the viral load and transmissibility in children.

Could COVID-19 vaccinations or prior infections protect against other coronaviruses?

A new study provides encouraging proof of the feasibility of this project, showing that both natural infection with and vaccination against SARS-CoV-2 are associated with an increase in cross-reactive antibodies against other CoVs.

Around 5% of children develop long COVID-19 symptoms, suggests new study

A new study, by researchers at University College London (UCL) in the UK, shows that even though children rarely develop symptomatically severe COVID-19, the prevalence of long COVID in children with a history of infection is over 4.5%.

Study explores therapeutic potential of exploiting autophagy cascade against COVID-19

Researchers recently reviewed current knowledge on links between autophagy and coronaviruses and how this knowledge can be used to repurpose autophagy modulators as potential treatment options for COVID-19. The review is published in the journal Frontiers in Microbiology.

Study shows why COVID-19 has widely varying outcomes in different people

The answer is something infectious disease experts are working to uncover. As COVID-19 revealed, the same pathogen can have widely varying outcomes in different people.

High baseline levels of inflammatory cytokines linked to thrombotic events in patients with COVID-19

In a recent open-access paper published in the Journal of Clinical Medicine, researchers from Iran and Germany show that high baseline levels of inflammatory cytokines measured during admission put patients with coronavirus disease (COVID-19) at increased risk of developing coagulopathy, thrombotic events – and even death.

Mason researchers examine the potential anti-coronavirus activities of an over-the-counter drink

Could an over-the-counter health "shot" help fight COVID-19? George Mason University researchers think it just might.

SARS-CoV-2 evades neutralizing antibodies and rapidly spreads by cell fusion, finds study

In a new study by researchers in the UK, Germany and South Africa, this process is visualized using time-lapse microscopy of a human cell lung line, demonstrating that SARS-CoV-2 can induce cell-to-cell fusion within 6 hours post-infection. Further, the application of neutralizing monoclonal antibodies or convalescent plasma was unable to prevent the spread of the virus by this mechanism, suggesting that removing SARS-CoV-2 from cells permissive of cell membrane fusion could be more difficult than other types of cell.

Novel insights can open doors to combating clotting-related problems in COVID-19

Researchers scour what is known to come up with a hypothesis of why blood clots can be a major problem in COVID-19

Mast cell activation may underlie inflammation in severe COVID-19

A new preprint research paper posted to the medRxiv* server points to mast cells as major culprits in the etiology of severe and critical COVID-19. This could suggest suitable therapeutic and preventive interventions to reduce the morbidity and mortality of this viral illness.
