Helminths are very successful at regulating host immune responses to evade rejection and as a consequence may also protect the host from certain autoimmune diseases. Clinical trials are underway to determine if reintroducing helminths to patients may be a viable therapeutic strategy. In a Pearls article, Girgis et al. review features of the immune response against helminths, focusing in particular on immune regulation. The picture shows Trichuris trichiura eggs inside a female worm from an infected individual.
