How would glutathione in the form supplied in the Ultrathione he took prevent or block the pathway viral RNA takes into the DNA of human cells to cause them to replicate the flu virus? The figure leading this post shows how the virus disturbs the redox (reduction/oxidation) state of the cell to promote replication of the flu virus. It is from an article, free to all from New MIcrobiologica at http://www.newmicrobiologica.org/PUB/allegati_pdf/2007/4/367.pdf. The article points out that viruses induce an imbalance of the cellular redox state toward a pro-oxidant condition. These alterations trigger pathways the virus uses to replicate. The pathways are shown in the leading figure. After the virus enters the cell, the viral vRNPs are transported to the host-cell nucleous where they use the cell's own gene expression to undergo transcription and replicatation. Think of the viral infection as an epigenetic event that alters expression of our genes, the first event is the viral invasion of the cell, the second event is its entry into the nucleous, the third event is its incorporation into our genes and take over part of the transcription and expression machinery to replicate itself.
Glutathione helps prevent the virus from using the host-cell's own genetic machinery to replicate. They must use this machinery because they lack their own means of replication. Glutathione prevents the redox imbalance the virus uses to open those pathways to the nuclear DNA of our cells. Glutathione also captures the virus and exports it from the cell nucleous. Guardian, available at this site through the links provided, contains Ultrathione, the same advanced form of glutathione used by this brave scientist. It is the same glutathione that I have taken for about 30 years that kept me from falling victim to the flu while my colleagues caught it. I don't think my resistance was due any superior immunity on my part since I had the flu as often as anybody before I began taking Ultrathione.
