More interesting research into Long COVID, Chronic Fatigue Syndrome, latent viruses and how they can trigger the immune system to damage healthy tissue:
Anders Rosén describes what happens as a domino effect: infection with a new virus, SARS-CoV-2, can activate other, latent, viruses in the body. The researchers suggest that this can, in turn, give rise to a chain reaction with an elevated immune response. This can have negative consequences, one of which is that the immune system attacks certain tissues, such as nerve tissue, in the body. Previous studies have also shown that the mitochondria, which produce energy in the cells, are affected, which suppresses the energy metabolism of people with ME/CFS.
"Another important result from the study is that we see differences in antibodies against the reactivated viruses only in the saliva, not in the blood. This means that we should use saliva samples when investigating antibodies against latent viruses in the future," says Anders Rosén.
