I’m afraid I don’t have much interesting to say about this link, but I just can’t scrape my jaw off the floor. There’s a story on Alternet about the incidence of autoimmune disorders, The Autoimmune Epidemic: Bodies Gone Haywire in a World out of Balance. I’m simply floored by some of the accounts, the numbers, and the whole phenomenon. I wish I had something to add, but I thought the least I could do was point out the story to some of our readers.
The autoimmune system is of special interest to those of us concerned about how environmental factors affect the development of organisms, including humans, because it is one of the clear cases of a system that gets substantial input from the environment to accomplish basic functions. We also find that it offers all sorts of interesting examples of non-genetic forms of heredity, including influences in utero and the widely-recognized importance of breast feeding for shaping the immune system. Less widely understood are the effects of changing environment on immune system functions in things like allergies.
