When you become sick, your immune system releases inflammatory proteins called cytokines that tell your immune cells how to fight the infection. Another top story was about a recent presentation on cytokine storm syndrome. Cytokines storm occurs when the body, in an attempt to kill the virus, attacks its own cells and tissues. During a cytokine storm, your body goes into an overactive immune response that can ultimately lead to organ failure. Understanding Omicron, the new COVID-19 variant of concern Trish Perl, M.D. The scientists found that an extract of photosynthetically enhanced Spirulina reduces by 70 percent the release of an immune-system protein that can cause a cytokine storm in the lungs leading to acute respiratory distress and organ damage.
