Study Reveals 'Zombie' COVID-19 Fragments Attack Immune Cells, Impacting Long COVID Sufferers
A recent study involving an international team of over 30 researchers has uncovered that remnants of the COVID-19 virus, described as 'zombie' fragments, continue to affect the immune system by targeting specific immune cells. These fragments, which remain after the virus is destroyed in the body, are believed to contribute to the inflammation and immune cell destruction seen in long COVID patients. The study highlights that these viral fragments preferentially suppress cells with certain membrane curvatures, including dendritic cells and T cells, which are crucial for immune response. The research also notes that the Omicron variant of COVID-19 breaks down into a greater variety of protein fragments compared to previous strains, potentially explaining its high infectivity but lower severity. Despite the perception that the pandemic is over, COVID-19 continues to cause significant mortality and long-term health issues in the U.S.
