Send A team of researchers in the US have found that exposure to the SARS-CoV-2 spike protein alone was enough to induce Covid-19-like symptoms, including severe inflammation of the lungs.
New York:
SARS-CoV-2, the virus that causes Covid-19, is covered in tiny spike proteins. These proteins bind with receptors on our cells, starting a process that allows the virus to release its genetic material into a healthy cell.
The researchers from Old Dominion University, Virginia, US, developed a genetically modified mouse and injected it with a segment of the spike protein and analysed their response 72 hours later. Another group of mice received only saline to serve as control.

COVID Spike Protein Alone may Cause Lung Inflammation by Colleen Fleiss on April 28, 2021 at 11:22 PM
Exposure to SARS-CoV-2 spike protein alone was enough to induce coronavirus-like symptoms, including lung damage and severe lung inflammation, said researchers.
The researchers from Old Dominion University, Virginia, US, developed a genetically modified mouse and injected it with a segment of the spike protein and analysed their response 72 hours later. Another group of mice received only saline to serve as control.
The genetically modified mice exhibited Covid-19-like symptoms that included severe inflammation, an influx of white blood cells into their lungs and evidence of a cytokine storm an immune response in which the body starts to attack its own cells and tissues rather than just fighting off the virus. However, the mice that only received saline remained normal, the results showed.

Study reveals Coronavirus spike protein alone may cause lung damage
In India, the second wave of coronavirus is rapidly spreading its wings and has left people helpless. There s a shortage of hospital beds, oxygen cylinders, Remdesivir that has created a wave of tension in the country. On Wednesday, India recorded a massive surge of 360,960 new COVID-19 cases and 3,293 new deaths, the highest spike so far, according to Health Ministry. With this, the total caseload stands at 17,997,267 while the death toll from the deadly coronavirus has crossed the 200,000-mark. Now a latest study found that exposure to the SARS-CoV-2 spike protein alone was enough to induce Covid-19-like symptoms, including severe inflammation of the lungs.
