Patent Title  Application of polypeptide and polypeptide combination in improvement of antiviral immunity

Comment 

Abstract  The invention belongs to the field of biological medicines, and particularly relates to a polypeptide and an effect of a polypeptide combination in improvement of antiviral immunity. The invention proves that the polypeptide or polypeptide combination containing 9 amino acids (PKCPEPCPP), for example, SPRR2 family polypeptide (such as antibacterial peptide SPRR2A from a host) can effectively activate a natural immune signal channel, can be used as an endogenous agonist of TLR9, is crucial to activation of the SPRR2 family mediated TLR9 signal channel, and has a remarkable effect in the aspect of virus resistance for the first time.
