This is Scientific American's 60-Second Science. I'm Karen Hopkin. This will just take a minute.
Sometimes a bit of bacteria can be just what the doctor ordered. If you prize yogurt for its “active cultures,” you know what I’m talking about. Now a new study, published in the September 21st online issue of Nature, suggests that good bugs1 might even hold diabetes2 at bay. Type I diabetes is caused by an immune system malfunction3. Basically, the immune cells that usually chase after bacteria instead attack the pancreas, wiping out the cells that produce insulin. So researchers decided4 to see what would happen if they reigned5 in the immune response in mice that are prone6 to diabetes.
As expected, they found that the animals were less likely to develop the disease. But the effect depended entirely7 on the critters having a normal complement8 of friendly bacteria in their intestine9. Mice that were raised in a totally sterile10, germ-free environment were rampant11 diabetics. But simply treating those mice with a cocktail12 of bugs found in most mammals’ bellies13 cured the disease. How bacteria in the intestine can stave off diabetes is not yet clear. But the finding could lead to some interesting new treatments. In the meantime, remember that we can't live without the stuff that lives in us.
Thanks for the minute for Scientific American's 60-Second Science. I'm Karen Hopkin.
