Research published in the Dec 15th issue of the journal Immunity has found that infections alter the expression of host genes. The changes that result from infection are different for viruses and bacteria and may be used in the future as a way to distinguish viral infections from bacterial ones. Additionally, they found that the expression of a group of 11 genes were altered by the influenza virus and this could serve as a useful way to distinguish influenza from other viral infections. They found that the influenza vaccine led to the same changes in gene behavior. There is hope that this could be a way reduce the overuse of antibiotics by identifying more accurately which infections are viral and therefore not appropriate for antibiotic treatment.
From this article in Science News about this research and what it means:
This is the abstract for the journal article itself:
While this research looked at the effects on human genes for three viruses, it seems likely that at least some other viruses have this effect as well. This is particularly interesting since ME/CFS and Fibromyalgia often begin with a viral infection that seems to act as a trigger, maybe this is how? Maybe some people have some problem with the mechanism that corrects these changes after infection, if that happens, or maybe the way the gene expression is altered is not the same in some people, or maybe there are mutations in these genes that do not become apparent until their expression is changed in this way? I also can't help but wonder if the flu vaccine alters DNA expression, maybe other vaccines do as well, and again maybe this plays a role in the onset of some adverse reactions and disorders that can follow vaccination?
