Identifying the pharmacological activity of bioactive peptides is an active area of research and one that has already shown promise in the medicinal field, with discoveries of antitumoral, antiviral, antifungal, and antimicrobial peptides. We are presently involved in identifying and characterizing a bioactive peptide which stimulates the immune system.
Animal models have been developed which show that, although the peptide does not possess bactericidal or viricidal activity, it is able to significantly improve the survival of mice infected with Salmonella typhimurium and chickens infected with Pasteurella multocida. The peptide has also been shown to be effective as a therapeutic agent in the treatment of canine parvovirus and equine lower respiratory disorder.
Current studies are focusing on the ability of the immunomodulator to decrease tumor load in mice challenged with B16 lung melanoma, and the elucidation of the immune response precipitated by the peptide.
