According to multiple studies, 9 out of 10 people carry the gene for
herpes simplex virus type 1 (HSV-1). The only question was, why is it that if 90 percent of people carry the gene, only 20 percent of the population shows symptoms? Recently, researchers from the University of Edinburgh, in Scotland, did a study taking blood samples from 20 people with cold sores. When looking at their genes, the blood work showed that those with the cold sores had a mutation of the gene
IL28B. The researchers discovered that people who do not produce cold sores, those without the mutation, are able to produce the protein that keeps the virus inactive. Therefore, those who do produce cold sores, who have the mutated IL28B gene, is not able to produce that protein and are then unable to have their immune system keep the virus under control. Researchers now hope to find a way in which we can utilize this protein as a possible treatment for other infections caused by the HSV-1.
I found this to be very interesting, seeing as that my mom and my aunt both produce cold sores; therefore, they would have the IL28B mutation. This then means, that even though I, myself, do not produce cold sores, I could still carry the HSV-1 gene. Hopefully, researchers can find a way, just like they did for insulin and diabetes, to use the IL28B protein as a cure for HSV-1 and its related viruses.
