Welcome to ThisIsMS. Your speech recognition program seems to work fine except it thinks it's English. English people always have a hard time spelling some words like 'programme'. In good ol' American we take shortcuts and settle for 'program'. I guess those two extra letters can make it sound more sophisticated. Of course, the software was probably developed in India to run on Taiwan-manufactured hardware. The world has really become a global place! (if I can coin a Yogi-ism)
As I gather, you are suggesting that recycled snot is the problem. Or more specifically, intact cells within the aforementioned snot. You might have something interesting there, but perhaps at a subcellular level.
When the purpose of the small intestines is discussed in biology, it is usually described as the section in the GI tract where small molecules are transferred from the digested material to the blood system: small molecules like amino acids, sugars, simple carbohydrates. It was thought that everything was broken down to simple molecules by the aciditiy of the stomach, and the enzymes (trypsin, pepsin, chymotrypsin, glycosylases, etc.). Proteins, sugars, fats are all broken down to simple amino acids, simple sugars (glucose, fructose) and then transferred into the blood system. These then could cross the intestinal barrier and be absorbed into the blood system, to circulate to the liver and individual cells. Then, in the Krebs cycle (or TCA cycle) that everyone in biochemistry memorizes (and then forgets), the simple two and three carbon molecules are used to manufacture whatever the cell requires at that moment. By restricting the size of molecules that can cross the intestinal barrier, it can prevent invasion by bacteria and some toxins.
In the past 10 or so years we have heard concern about genetically engineered foods, that perhaps larger molecules, like hormones and steroids, could be passing through the intestines and having a greater effect than we would normally expect from our typical hamburger or whatever. That seems to be a realistic concern since hormones are not necessarily much different from amino acids in size and overall electrostatic charge at normal pH (i.e. normal acidity levels). I can't say for sure whether this is something we should be concerned about. I guess in my most simplistic logic I am thinking: estrogen from a cow or protein for macho muscle mass, what am I getting from my hamburger?
Maybe some more onions will make it more macho.
Anyway, I digress. There is an autoimmune disease called cilliac sprue which affects primarily middle aged Caucasian males where they have an autoimmune reaction to gluttin from wheat. Again, in simplistic Wesley thinking, the wheat in the hamburger bun is the problem, not the meat.
Cilliac sprue is an allergic reaction to the gluttin protein in the wheat found in most breads. So this is a protein, not just the amino acid sized material, that is causing a problem in crossing the intestinal barrier. Cilliac sprue usually displays as an inflammation of the intestinal lining and is analyzed as an autoimmune reaction. So, we can begin to think of autoimmune reactions at the protein level, not just the amino acid level. But the typically protein might have 300 amino acids. What you are suggesting with regard to whole cells crossing the intestinal barrier is like the size of an elephant (a protein) to the size of Kenya (a cell). For a cell to pass intact through the stomach (acidity and enzymes) and then pass through the intestinal barrier with enough antigenicity remaining seems like a long stretch. But proteins from snot, that is a possibility. Autogenicity of proteins from dietary material is probably a better, broader way to describe the theory. Cells in snot, I don't see it but perhaps some proteins from snot. I am willing to listen if you can think of more details. You seem imaginative TwistedHelix so lead-on and impress us with your logic.
PS: Snot, is that the English or the American spelling? Sounds more American to me. Snothe, would sound more English.
