Scientists say Covid 19 has lung damage due to persistence of ‘abnormal cells’

LONDON: Scientists have analyzed organ samples from 19 dead Covid patients and found extensive lung damage due to the persistence of abnormal “fused cells” that shed more light on the progression of the disease. Is.
Researchers, including those from King’s College London in the UK, examined the behavior of the novel corona virus SARS-Co-2 in the lungs, heart, liver and kidneys of 41 patients who died in Covid 19. Tested samples.
In the study, published in the journal EBO Medicine, they uncovered unique features of the virus that may explain why some patients experience symptoms for months – called ‘long coyotes’.
The results show extensive lung damage in most cases, with patients experiencing severe obstruction of normal lung structure and conversion of respiratory tissues into fibrous matter.
According to the scientists, about 90% of the patients showed additional features that were quite unique to Covid-19 compared to other types of pneumonia.
He said that there was bleeding in the arteries and veins of the lungs and that many of the cells in the lungs had very large nuclei abnormally large, resulting in fusion in the single large cells of different cells.
The researchers noted that the formation of fuse cells – sensory – is caused by a viral spike protein, which the virus uses to enter the cell.
When prodrug is present on the surface of cells infected with the covid-19 virus, studies have shown that it stimulates their fusion with other normal lung cells, which can cause inflammation and thrombosis.
Research has shown long-term persistence of the virus genome in respiratory cells and blood vessels in stratum corneum, as well as in infected cell sensations.
According to the researchers, the presence of these infected cells can cause major structural changes in the lungs, which can persist for weeks or months and eventually explain the ‘long coid’.
“These results indicate that covid-19 is not just a disease caused by the death of infected cells, but that these abnormal cells may remain in the lungs for a long time.” Educated at King’s College London.
