A contagious new COVID-19 variant called NB.1.8.1, aka "Nimbus," is now dominant in the United States, CDC data show. What to know about symptoms and vaccines.

The team also discovered that a specific W682R mutation near the furin cleavage site in the viral spike protein may contribute to the enhanced infectivity and inflammation observed in the P7 strain.

Results: Spike protein, SARS-CoV-2 infection related, accelerates cell aging by upregulating Cdc42 expression, which furtherly activated the Wnt/β-catenin signaling pathway. Conversely, treatment with ...

New Delhi: Changes in the spike protein enhanced the ability of the coronavirus to infect the brain, which could underlie the brain-related symptoms of the disease, including brain fog of long ...

Mice received the Spike protein preparations or the SARS-CoV-2 VLPs by intranasal instillation, while only the Spike proteins were injected intravenously or subcutaneously. Figure 1. Lung images ...

Methods: MCA/FeCl 3 thromboembolic model was induced in humanized ACE2 knock-in mice. hACE2 mice were treated with Losartan, an angiotensin receptor blocker, after one day of SARS-CoV-2 spike protein ...

Vaccine-makers should stop including the spike protein of the original SARS-CoV-2 coronavirus in covid-19 booster jabs to make them more effective against current variants, a study of antibody ...

SARS-CoV-2 spike protein persisted in the skull and brain, mouse and human autopsy data showed. In mouse models and human postmortem samples, SARS-CoV-2 spike protein was found in the skull marrow ...

New research reveals that mutations in the stem of the SARS-CoV-2 spike protein led to the virus becoming progressively tighter over time, which may have improved the virus's ability to transmit ...

Structural mass spectrometry reveals conformational changes in emerging SARS-CoV-2 spike protein variants that correlate with increased viral fitness.

University of Sydney scientists have discovered a protein in the lung that naturally blocks SARS-CoV-2 infection opening a pathway for new COVID-19 drug development.

Free Spike Protein of mRNA COVID-19 Vaccines Implicated in Myocarditis Researchers have found circulating spike protein in the bodies of people with the complication, pointing to a potential mechanism ...
