Long Covid research
Article in the Times about yet another long covid research path going on. The long and short of it is, a covid infection can change the immune system and what genes it expresses, resulting in constant inflammation for at least a year after initial infection. In other words. After infection. Your immune system is then constantly triggering and spreading inflammation all around the body. By analyzing those stem cells, “what’s clear is that the immune system is fundamentally changed after a severe infection like COVID-19,” he says. These cells contain genetic changes that alter which genes they express, skewing them toward generating more inflammatory factors. The change lasts for at least a year following a severe COVID-19 infection. Since these stem cells are responsible for producing more copies of innate immune cells, the changes in the genes they express are carried over to the new generations of cells they make. When he studied the cells in a dish, Josefowicz found that...
