There are several hundred distinct human cell types. … Cell types can be classified by their tissue of origin. However, it is possible for some cells to have their behavior induced by surrounding tissue.So, if there are several hundred distinct human cell types, how many distinct autoimmune antibodies can there be? I know, this comparison is a bit lopsided, but still: Do we know all possible autoimmune diseases?
What kind of disease could we cause, if we would pick one cell type, target it with inflammation and/or antibodies? Is early hair-loss a autoimmune disease of certain hair-cells? Is tinnitus a autoimmune disease of certain auditory cells?
And do we know all hormones? All hormone producing cells? Or just the "important" ones? What happens if the cells responsible for a lesser hormone fail?
