Joy of Sharing ScienceC O V I D - 1 9 A N D C E L L SACE2 regulates blood pressure, however, once the spikes are attached, it allows themembrane of the cell and the membrane of the virus to fuse together. Spike proteinsundergo a conformational change to allow membrane fusion. When membranesare fused together, the virus releases its contents into the cell, which is RNA. Mostvaccine targets are the spikes on the virus because blocking its entry into the cell isthe most straightforward solution to prevent the virus from spreading.Typically, DNA of a cell is transcribed into messenger RNA (mRNA) insidethe nucleus, which then sets off to the ribosome in the cytoplasm. Ribosomesread out the RNA strand and translate it into amino acids that bind togetherand form a polypeptide chain, a protein.
How does coronavirus affect the body?In the case of coronavirus, released RNA directly goes to ribosomes totranslate its genetic material into new copies of the virus, which are essentiallyproteins. Some parts of the virus’s RNA code for specific proteins whichenable it to resist the cell’s innate immunity, prevent the host cell from sendingout signals for immune response, and encourage the host cell to release newlycreated copies of the virus.C O V I D - 1 9 A N D T H E R E S P I R A T O R Y S Y S T E MWhen SARS-CoV-2 contacts your mucous membranes and enters your body,it enters a healthy cell and starts duplicating. As the infection travels therespiratory tract, immune responses are triggered. Swelling and inflammationof lungs are common. The respiratory inflammations are detected with chestCT scans or chest X-rays. The frosted glass-like lung appearance indicatesinflammation.According to WebMD, 80% of COVID-19 positive patients present with mildor moderate symptoms like a dry cough or sore throat. In some cases theinflammation reaches the alveoli and pneumonia-like symptoms are seen. Theleading cause of death in COVID-19 patients is pneumonia and respiratoryfailure like ARDS (acute respiratory distress syndrome). Injury to alveolarepithelial tissue is the main cause of Covid related ARDS. This is characteristicto COVID-19 since a dry cough is considered a major symptom with minorinjuries to endothelial tissue resulting in no sputum production.
