Interferons (IFNs) are natural proteins produced by the cells of the immune system of most vertebrates in response to challenges by foreign agents such as viruses, parasites and tumor cells. Interferons belong to the large class of glycoproteins known as cytokines. Interferons are produced by a wide variety of cells in response to the presence of double-stranded RNA, a key indicator of viral infection.
My journey started on Jan 4th 2010 when I went to the dentist for a check up, something I hadnt done for a few years. She asked me if I was a smoker which I answered No and I have never smoked in my life... with that she said that I should go to my GP. I asked why and she said "you have a black mark on the roof of you mouth" and showed me with a mirror. It looked horrible.
