What is Helminth protein?

A helminth protein, or helminthic antigen, is a protein derived from a parasitic worm that causes an immune reaction. When secreted, these proteins may modify the host's immune response in order to promote longevity of the parasite. Helminth proteins can result in a deregulated response to infection, and are implicated in reduced reactivity to other antigens. Other helminth proteins promote parasite survival in other ways, particularly since parasites must depend on hosts for the supply of essential nutrients. Despite their pathogenic properties, helminth proteins have potential to be co-opted to treat a number of other human diseases.
