Coronavirus protein may cause lung damage

New York – A team of researchers from Old Dominion University, Virginia, 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. 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. They developed a genetically modified mouse and injected it with a segment of the spike protein and analysed their response 72 hours later. Pavel Solopov, Assistant Professor at the varsity, said: “Our findings show that the SARS-CoV2 spike protein causes lung injury even without the presence of intact virus.This previously unknown mechanism could cause symptoms before substantial viral replication occurs.”
