Outline of Final Research Achievements |
The purpose of the present research is to search the activities of synthetic peptides constituting IFN-τ for a possible substitution for recombinant IFN-τ. Eleven peptides (long chain: 27-28 aa, short chain: 7-17 aa) have been chemically synthesized from amino acid sequence and structure of IFN-τ. Each or mixed peptides or recombinant IFN-τ were added to cultured bovine endometrium stromal cells to detect the expression of MX1, 2 and ISG15 that belong to interferon-stimulated genes (ISGs). Next, each or mixed peptides were added to the cells with recombinant IFN-τ and expression of ISGs was evaluated.IFN-τ significantly stimulated ISGs expression, whereas all single or mixed peptides did not. Addition of single or mixed peptides did not show the inhibitory effect of IFN-τ.These result suggest that synthetic peptides would not have agonist and antagonist ability or binding to IFN receptor by the possible structural change.
