Use of the PACAP as a molecular adjuvant for vaccines

摘要

The invention relates to the use of the pituitary adenylate cyclase-activating polypeptide (PACAP) as a molecular adjuvant for vaccines. Along with other applications, said vaccines can be used for protection against infectious agents such as viruses, bacteria and ectoparasites that affect mammals, birds and aquatic organisms. The PACAP, combined with a specific antigen, exhibits the effectiveness thereof as an adjuvant as it increases the immunological response of the host against said antigen. This type of response can be observed when the vaccine compositions or combinations comprising PACAP are administered orally, by an injection, or by dipping tanks in the case of aquatic organisms.
