Pre-existing anti-IFN autoantibodies may worsen COVID-19 in lupus patients

“Our observations suggest that the presence of these autoantibodies may predispose SLE patients to infection with SARS-CoV-2 with a more severe presentation and represent an additional risk factor in this patient population,” write Sarthak Gupta and colleagues from the National Institute of Arthritis and Musculoskeletal and Skin Diseases in Bethesda, Maryland.

RNA-binding proteins may suppress antiviral defenses against SARS-CoV-2

Conducted by researchers in South Korea at the Institute for Basic Science and the International Vaccine Institute, a new study published on the preprint server bioRxiv in November 2020 describes the many host proteins that bind with the ribonucleic acid (RNA) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and regulate the replication of the virus.

Correlations found between 'long-COVID' patients and preexisting health conditions

Researchers from the nference (a biotech information firm) in Cambridge, MA, USA, the Mayo Clinic in Rochester, MN, USA, and nference Labs based in Bengaluru, India, recently performed a retrospective analysis of 266 COVID-19 patients.

Researchers investigate the effect of palm oil extract on mice liver cells

Palm oil contains abundant quantities of vitamin E compounds, which include tocopherols and tocotrienols.These compounds have anti-oxidant effects, which protect cells from damage from toxic chemical produced by metabolic processes.

Research finds detectable but low-level SARS-CoV-2 contamination on public surfaces

A team of researchers at Tufts University found that 8.3 percent of surface samples tested positive for SARS-CoV-2, including crosswalk buttons, trash can handles, and door handles of essential business entrances such as grocery stores, banks, gas stations, and liquor stores.

5-amino levulinic acid inhibits SARS-CoV-2 infection in vitro

Researchers tested 5-amino levulinic acid in vitro in human-derived cells and found it prevents severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Because it is safe and ubiquitous in plants and animals, it could be a potential drug against SARS-CoV-2.

Study analyzes the viral load on Halloween candy handled by COVID-19 patients

Like a specter, the question looms: How risky is trick-or-treating with SARS-Cov-2, the virus that causes COVID-19, in the air -- and possibly on the candy?

Mouth may be primary route of SARS-CoV-2 infection and transmission

A new study published on the preprint server medRxiv in October 2020 shows that the virus also multiplies robustly in the oral cavity, indicating that saliva plays a role in viral transmission.

Study: Nearly 17% of recovered COVID-19 patients could still carry the virus

A new study in the American Journal of Preventive Medicine, published by Elsevier, presents new data that address important questions pertaining to the containment of the coronavirus pandemic: When should COVID-19 quarantine really end and which continuing symptoms may be more indicative of a positive test in recovered patients?

Scientists uncover surprising players in acute liver failure

Acute liver failure is a devastating, rapidly progressing disease that results in death in 80% of cases, unless an emergency liver transplant is performed. In the developed world, its leading cause is a substantial overdose of acetaminophen, also known as paracetamol.

Advancements in research on cancer signal transduction and treatment

Cancer is driven by numerous genetic and epigenetic changes occurring at the cellular level. These changes drive normal cells to proliferate and escape processes that usually regulate their survival and migration.

Proton regulator of essential cancer miRNA discovered

MicroRNAs (miRNAs) are evolutionarily conserved small noncoding RNAs - bits of genetic code that serve as critical gene regulators in many aspects of biological processes important for human health.

Interaction between PTSD and klotho gene may cause premature aging in the brain

Study Finds PTSD Interacts With Klotho Gene, May Cause Premature Aging In The Brain

Novel insights open up new avenues for treating autoimmune conditions

Immune response is a balancing act: Too much can lead to inflammatory or autoimmune disease; too little could lead to a serious infection. Regulatory T cells, or Tregs, are important players in striking this balance, acting as "brakes" on the immune response so it doesn't go overboard.

Study suggests 5’UTR of SARS-CoV-2 might be of pangolin coronavirus origin

Findings from a new genomic sequencing study support the hypothesis that the pangolin was the intermediate host for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that enabled transmission of the virus to humans.

Population-based COVID-19 prevalence surveys in Europe and Americas show risk of bias

A team of researchers from the Federal University of Health Sciences of Porto Alegre and the Federal University of Rio Grande do Sul performed a systematic review to assess these population-based COVID-19 prevalence surveys' reliability and biases qualitatively. Their study is published on the preprint server medRxiv.

Researchers present COVID RdRp structure at 2.5A

In a recent bioRxiv* preprint publication, Christopher J. Russo et al. report the structure of favipiravir ribonucleoside triphosphate (favipiravir-RTP) in complex with the SARS-CoV-2 RNA-dependent RNA polymerase (RdRp) bound to a template: primer RNA duplex. They determine the structure by electron cryomicroscopy (cryoEM) to a resolution of 2.5 Å.

New inhibitor of SARS-CoV-2 RNA translation

As the search for effective severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inhibitors continues, a recent study by Yale University School of Medicine researchers published on the preprint server bioRxiv in October 2020 reports the inhibitory effect of the drug merofloxacin on frameshifting during SARS-CoV-2 replication.

Biomimetic virus-like particles for safer positive controls in SARS-CoV-2 detection

In an attempt to overcome these issues, a team of researchers from various departments at the University of California San Diego recently proposed using biomimetic virus-like particles (VLPs) as positive controls for assays used in SARS-CoV-2 detection. Their study is published on the preprint server bioRxiv.
