I've talked about miocenia gravis; there is it's rarer cousin, the syndrome, which sometimes associates with carcinoma of the lung, and we have shown that this too is an auto-immune disease in which the lung cancer seems to precipitate the immune system into making an antibody against it, the tumour, and the because the tumour has on its surface the same thing as the nerve terminal, the antibody also binds to the nerve terminal and causes trouble there.
