A modified Ac-TMP-2 protein lacks one or a plurality of acidic C-terminal amino acids normally present in a full-length or wild-type Ac-TMP-2 protein and may also lack one or a plurality of N-terminal amino acids while retaining the amino acid sequence C-S-C at or near the N-terminus. The modified Ac-TMP-2 protein may be useful in method and composition for reducing or alleviating inflammation in a subject. Inflammation may be associated with a disease is a disease of the digestive tract such as chronic gastritis or an inflammatory bowel disease such as Crohn's disease or ulcerative colitis, or a disease of the respiratory system, such as asthma, emphysema, chronic bronchitis, and chronic obstructive pulmonary disease.
