| The aim of this study was to identify novel TNF-α blocking peptide(s) using phage display technology. Two novel 7-mer TNF-α binding peptides P51 and P52 with Kd values of 1.47 and 0.51nM were identified. Phage particles displaying P51 and P52 peptides at 0.318nM concentration prevent cytotoxic effect of TNF-α on L929 cells by 8.2% and 16.15%, respectively. Synthesized P51 and P52 peptides also inhibited TNF-α induced cytotoxicity with IC50 values of 25.15±2.18 and 7.08±2.24μM, respectively. The result of RT-PCR also supports the inhibitory activity of the identified peptides, where P51 and P52 significantly inhibit the inductive effect of TNF-α on IκB-α mRNA levels. The inhibitory effects of the peptides were attributed to their abilities of binding at the inter-subunit interfaces leading to TNF-α dissociation. The results of molecular docking studies revealed that the peptides-TNF-α complexes are mostly stabilized by hydrophobic contacts. |
