Mutations and natural selection can help subsequent versions of a virus get stronger and stronger in different ways, which seems to be happening with the Covid-19 coronavirus. And Eric Topol, MD, founder and director of the Scripps Research Translational Institute, has called the currently spreading version, the Omicron sub-variant BA.5, “the worst version of the virus
A team of Berlin-based researchers have simulated SARS-CoV-2 infection in human lungs, thereby generating key insights into the mechanisms involved. Using cultured lung tissue samples, the researchers showed that the virus responsible for COVID-19 has only limited capacity for directly infecting cells within human alveoli. The majority of viruses which reach the lungs are ingested by macrophages (cells of
Researchers are first to link COVID-specific T Cells to lung function, Long COVID A new study published in today’s issue of PLoS Pathogens is the first to link SARS-CoV-2 specific T cells to lung function and those who suffer from long-term COVID symptoms. Long COVID currently affects hundreds of millions of Americans. The study found that patients suffering
During the initial stages of cellular infection, SARS-CoV-2 releases a number of accessory proteins to help suppress and evade our immune system. ORF7a is one such protein. Suppression of the innate immune system is necessary for the virus to establish infection. The several-day suppression of the immune system by the virus also contributes to the
Mount Sinai study shows dramatic protective effects of vaccination in this high-risk population, which often demonstrates vaccine hesitancy Heart failure patients who are unvaccinated against SARS-CoV-2, the virus that causes COVID-19, are three times more likely to die if infected with the virus compared to fully boosted heart failure patients, according to new research out
In a retrospective study based on big data, the researchers found that Leukotriene Inhibitors (LTI)s prevented death in COVID-19 patients with low oxygen saturation University at Buffalo biomedical informatics researchers have found that patients hospitalized with COVID-19 pneumonia had a 13.5% survival advantage when treated with a combination of leukotriene inhibitors (LTIs) and the steroid
While risks higher for the unvaccinated, study points to need for more tools against the virus Vaccinated people with mild breakthrough COVID-19 infections can experience debilitating, lingering symptoms that affect the heart, brain, lungs and other parts of the body, according to researchers at Washington University School of Medicine in St. Louis and the Veterans
In severe covid-19 and long-term covid, disorders of blood coagulation often occur. Now, researchers at LiU have discovered that the body’s immune system can affect the nail protein on the surface of the sars-cov-2 virus so that it forms misfolded protein, so-called amyloid. The findings point to a possible link between harmful amyloid formation and covid-19 symptoms.
The inflammatory disorders share similar underlying molecular patterns, a UC San Diego study reports; findings may improve disease diagnosis and treatment and support new drug targets for MIS-C The emergence of COVID-19 had doctors racing to define and treat the new disease, but they soon discovered it was not the only novel illness caused by
Patients with severe COVID-19 who were given imatinib had lower mortality rates at 90-day follow-up, according to research published at the ATS 2022 international conference. The study investigated the long-term efficacy of imatinib in hospitalized COVID-19 patients in the Netherlands as part of the randomized, double-blind, placebo-controlled CounterCOVID study. A tyrosine kinase inhibitor, imatinib is currently an oncology
