The key isn't really in the hookworms, but the liquid that these worms secrete. There is a protein in the fluid called AIP-2, which when injected into mice, alleviates their auto-immune responses. In the experiment, the treated animals' diseases were almost completely reversed, and they also found that it shifted the balance of immune cells like T cells and dendritic cells. This can be helpful in battling harmful immune reactions in the lungs. Though the research is far away from any human testing, this may be a great discovery for treating diseases that cause a lot of ailment to humans. This experiment also shows that our relationship to parasites should be altered. Parasites are only known to be harmful to us, but if we open our minds, we can discover completely new helpful relationships with these organisms in order to improve our quality of life. In fact, the role could be completely reversed in which we harm those organisms for our own gain in health benefits.
