A team at University Hospitals in Cleveland aims to unearth potential immunologic mechanisms and understanding of COVID-19 upon long-term consequences and outcomes thanks to a grant from the American Lung Association.
What exactly triggers a sneeze? A team led by researchers at Washington University School of Medicine in St. Louis has identified, in mice, specific cells and proteins that control the sneeze reflex. Better understanding of what causes us to sneeze — specifically how neurons behave in response to allergens and viruses — may point to treatments capable of slowing the spread of infectious respiratory diseases.
A new study suggests the lungs may not be the main factor that reduce exercise ability in people recovering from severe COVID-19. Anemia and muscle dysfunction also play a role. The study is published ahead of print in the Journal of Applied Physiology. It was chosen as an APSselect article for May.
A leading South Australian immunologist has been awarded $3 million from the Federal Government to accelerate work on a locally developed Covid-19 vaccine, in what’s anticipated to be the second line of defence against the virus.
Scientists at the Weizmann Institute and the Israel Institute for Biological, Chemical and Environmental Sciences took a novel tack to investigating SARS-CoV-2’s powerful ability to infect, finding that the virus deploys an apparently unique three-pronged strategy to take over the cell’s protein-synthesis abilities. The work could help develop effective Covid-19 treatments.

The COVID-19 pandemic has caused an unprecedented disruption in supply chains across multiple sectors including the shortage of critical personal protective equipment (PPE). In addition to hand washing and social distancing, various PPE items are used to prevent contact with…
Because COVID-19 has been detected in urine and stool samples, public restrooms can be cause for concern. Researchers measured droplets generated from flushing a toilet and a urinal in a public restroom and found a substantial increase in the measured aerosol levels in the ambient environment with the total number of droplets generated in each flushing test ranging up to the tens of thousands. Due to their small size, these droplets can remain suspended for a long time.
Although antibodies induced by SARS-CoV-2 infection are largely protective, they do not completely protect against reinfection in young people, as evidenced through a longitudinal, prospective study of more than 3,000 young, healthy members of the US Marines Corps conducted by researchers at the Icahn School of Medicine at Mount Sinai and the Naval Medical Research Center, published April 15 in The Lancet Respiratory Medicine.
A new computational study suggests that a protein present in SARS-CoV-2, the virus that causes COVID-19, could be a target for future vaccines. The study is published ahead of print in the American Journal of Physiology-Lung Cellular and Molecular Physiology.
University of Maryland School of Medicine (UMSOM) researchers have identified the most toxic proteins made by SARS-COV-2—the virus that causes COVID-19 – and then used an FDA-approved cancer drug to blunt the viral protein’s detrimental effects.

In lab-dish experiments, the mutant virus escaped antibodies from the plasma of
COVID-19 survivors as well as pharmaceutical-grade antibodies
Mutations arose in an immunocompromised patient with chronic SARS-CoV-2 infection
Patient-derived virus harbored structural changes now seen cropping up independently in samples across the globe
Findings underscore the need for better genomic surveillance to keep track of emerging variants
Results highlight importance of therapies aimed at multiple targets on SARS-CoV-2 to minimize risk of resistance
Myocarditis can affect anyone, even healthy young adults and children. Adenoviruses and enteroviruses, such as Coxsackieviruses (hand, foot and mouth disease), are among the most common culprits. But SARS-CoV-2 (COVID-19) may cause heart inflammation, too. And, as we are learning, COVID-19-related inflammation can have a long-term impact on heart health.
Texas Biomedical Research Institute received two Department of Defense (DoD) Defense Health Agency subcontracts, totaling nearly $2 million, to assess the efficacy of surface coating and aerosolized decontamination technologies to combat SARS-CoV-2 on surfaces and in the air.
A specific wavelength of ultraviolet radiation killed more than 99.99% of SARS-CoV-2, the virus that causes COVID-19, in laboratory tests, a new study has found.
A new SARS-CoV-2 vaccine candidate, developed by giving a key protein’s gene a ride into the body while encased in a measles vaccine, has been shown to produce a strong immune response and prevent SARS-CoV-2 infection and lung disease in multiple animal studies.
Since the beginning of the pandemic, once-esoteric scientific terms have become common parlance—spike protein, PCR, mRNA.
Pathogenesis is not one of them. Yet, when it comes to understanding COVID-19, this may well be the most important word that has yet to make its way into the mainstream lexicon.
ROCKVILLE, MD – The virus that causes COVID-19 belongs to the family of coronaviruses, “corona” referring to the spikes on the viral surface.
ROCKVILLE, MD – If the coronavirus were a cargo ship, it would need to deliver its contents to a dock in order to infect the host island.
ROCKVILLE, MD – Coronavirus outbreaks have occurred periodically, but none have been as devastating as the COVID-19 pandemic.
ROCKVILLE, MD – One thing that makes SARS-CoV-2, the virus that causes COVID-19, elusive to the immune system is that it is covered in sugars called glycans.
A new review suggests that blood vessel damage and impaired oxygen delivery related to COVID-19 play a role in mood changes and cognitive difficulties that people with the disease face during illness and recovery. The review is published in Physiological Reports.
Fool the novel coronavirus once and it can’t cause infection of cells, new research suggests. Scientists have developed protein fragments that bind to the Spike protein, effectively tricking the virus into “shaking hands” with a replica rather than the receptor that lets the virus into a cell.
Researchers from Rutgers Cancer Institute of New Jersey evaluated the frequency of SARS-CoV-2, the virus that causes COVID-19, on various environmental surfaces in outpatient and inpatient hematology/oncology settings located within Rutgers Cancer Institute and Robert Wood Johnson University Hospital, an RWJBarnabas Health facility. The study, published in Cancer, revealed extremely low detection of SARS-CoV-2 on environmental surfaces across multiple outpatient and inpatient oncology areas, including an active COVID-19 floor.
New study suggests monetary reparations for Black descendants of people enslaved in the United States could have cut SARS-CoV-2 transmission and COVID-19 rates both among Black individuals and the population at large.
Researchers modeled the impact of structural racism on viral transmission and disease impact in the state of Louisiana.
The higher burden of SARS-CoV-2 infection among Black people also amplified the virus’s spread in the wider population.
Reparations could have reduced SARS-CoV-2 transmission in the overall population by as much as 68 percent.
Compared with white people, Black individuals in the United States are more likely to be infected with SARS-CoV-2, more likely to end up in the hospital with COVID-19, and more likely to die from the disease.
