title: Tuftsin a natural peptide with antiviral activity--structural basis of its action.
abstract: The influence of tuftsin--the natural phagocytosis stimulating tetrapeptide and its elongated analogues--on the mortality of encephalomyocarditis virus-infected NMRI mice was investigated. It seems that amino acids elongation in the parent peptide chain does not result in significant increase of antiviral activity of the compounds tested.
