Today I am going to talk about how our body reacts to the infection of corona virus. To know how it enters the cell and hacks it to produce its own copy click here . So, let’s start: - After infecting the cells and making multiple copies, these copies moves out from the cell by exocytosis. Now when the cell gets infected the cell releases certain intermediates: - 1.The Interferon α and β which goes to the healthy alveolar cells of vicinity and this results in the release of antiviral peptides (these peptides are kind of self-defense mechanism). 2.They also release Damage-associated molecular patterns (DAMPs are endogenous molecules that are released from damaged or dying cells and activate the innate immune system(macrophages) by interacting with pattern recognition receptors). Now these macrophages activate the inflammatory mediators (Interleukin1, interleukin 6, TNF- α ) so that they can be used to kill the virus. They also move to the pulmonary capillaries whic...
