Abstract
Brucellosis is a globally distributed zoonotic disease affecting animals and humans, and current antibiotic and vaccine strategies are not optimal. The surface-exposed protein Omp25 is involved in Brucella virulence and plays an important role in Brucella pathogenesis during infection, suggesting that Omp25 could be a useful target for selecting potential therapeutic molecules to inhibit Brucella pathogenesis. In this study, we identified, we believe for the first time, peptides that bind specifically to the Omp25 protein of pathogens, using a phage panning technique, After four rounds of panning, 42 plaques of eluted phages were subjected to pyrosequencing. Four phage clones that bound better than the other clones were selected following confirmation by ELISA and affinity constant determination. The peptides selected could significantly inhibit Brucella abortus 2308 (S2308) internalization and intracellular growth in RAW264.7 macrophages, and significantly induce secretion of TNF-α and IL-12 in peptide- and S2308-treated cells. Any observed peptide (OP11, OP27, OP35 or OP40) could significantly inhibit S2308 infection in BALB/c mice. Moreover, the peptide OP11 was the best candidate peptide for inhibiting S2308 infection in vitro and in vivo. These results suggest that peptide OP11 has potential for exploitation as a peptide drug in resisting S2308 infection.

Antimicrob Agents Chemother 2010; 54:3355-64. [PMID: 20479194 PMCID: PMC2916351 DOI: 10.1128/aac.01357-09] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2009] [Revised: 12/07/2009] [Accepted: 04/29/2010] [Indexed: 02/07/2023] Open
Abstract
Small peptides that inhibit the hepatitis C virus (HCV) at the stage of viral entry have the potential to serve as attractive antiviral drugs. Ribosome display is a cell-free system for in vitro selection of peptides from large random peptide libraries. Thus, we utilized a ribosome display library technique for affinity selection of HCV envelope protein E2-binding peptide ligands. Through 13 rounds of selection, the ribosome display system generated high-affinity 12-mer peptides, and the selected peptide PE2D (MARHRNWPLVMV) demonstrated the highest specificity and affinity to the HCV E2 protein. Furthermore, amino acids 489 to 508 (YPPRPCGIVPAKSVCGPVYC) of E2 were identified as crucial for binding to PE2D. The selected peptides, especially PE2D, not only dramatically blocked E2 protein binding to hepatocytes but also dramatically inhibited HCV cell culture (HCVcc) entry into hepatocytes. HCVcc and HCV particles from HCV patient serum samples could also be specifically captured using PE2D. Our study demonstrates that the newly selected peptide ligand PE2D holds great promise for developing a new molecular probe, a therapeutic drug specifically for HCV, or an early-diagnostic reagent for HCV surface envelope antigen E2.
