Synthetic long peptides that contain immunogenic T-cell epitopes have been used to induce activation of antigen-specific CD8 T cells in vitro for immune monitoring or adoptive transfer, or in vivo after peptide vaccination. However, the efficiency and mechanisms of presentation of exogenous long peptides in human leukocyte antigen (HLA) class I remain to be elucidated. In this study, we demonst...
OBJECTIVES The present study aimed to investigate the antimicrobial and biofilm inhibition activity of synthetic antimicrobial peptides (AMPs) against microbes such as Enterococcus faecalis, Staphylococcus aureus, and Candida albicans which are involved in endodontic infections. MATERIALS AND METHODS Agar diffusion test was done to determine the activity of peptides. The morphological changes...
Abstract Plant genomes encode hundreds of receptor kinases and peptides, but the number known plant receptor-ligand pairs is limited. We report that Arabidopsis leucine-rich repeat kinase LRR-RK MALE DISCOVERER 1-INTERACTING RECEPTOR LIKE KINASE 2 (MIK2) for SERINE RICH ENDOGENOUS PEPTIDE (SCOOP) phytocytokines. MIK2 necessary sufficient immune responses triggered by multiple SCOOP suggesting t...
We report the identification of a novel gene family (named MgCRP-I) encoding short secreted cysteine-rich peptides in the Mediterranean mussel Mytilus galloprovincialis. These peptides display a highly conserved pre-pro region and a hypervariable mature peptide comprising six invariant cysteine residues arranged in three intramolecular disulfide bridges. Although their cysteine pattern is simil...
We investigated the sequence regions of the human muscle acetylcholine receptor (AChR) beta subunit forming epitopes recognized by T helper cells in myasthenia gravis (MG), using overlapping synthetic peptides, 20 residues long, which screened the sequence of the AChR beta subunit. Since CD4+ lymphocytes from MG patients' blood did not respond to the peptides, we attempted propagation of beta s...
BACKGROUND Animal venoms are complex molecular cocktails containing a wide range of biologically active disulphide-reticulated peptides that target, with high selectivity and efficacy, a variety of membrane receptors. Disulphide-reticulated peptides have evolved to display improved specificity, low immunogenicity and to show much higher resistance to degradation than linear peptides. These prop...
The art of transforming peptides into drug leads is still a powerful and fertile field in medicinal chemistry discovery. Peptidomimetics can respond to peptide limitations by displaying higher metabolic stability, good bioavailability increasing receptor affinity selectivity. Various synthetic approaches strategies have been developed over the years order modulate conformational flexibility nat...
Oxidative coupling between tyrosine and tryptophan residues of peptides allows living organisms to produce highly intricate natural products. Their respective biosynthesis inspired synthetic chemists develop innovative strategies access these structurally challenging compounds. For more details see the Minireview by G. Vincent S. Tang on page 2612.
BACKGROUND hGlyrichin is a novel human antimicrobial peptide rich in glycine. The previous study of known human antimicrobial peptides indicated that in an eligible range, the greater corresponding antibacterial activity was consisted with the shorter peptide sequence. FINDINGS Two peptides named pCM19 and pCM12 were synthesized and the antibacterial activity assay results showed that these p...
No. down6848 Beamline(s): X28C The inability of current vaccines to offer complete protection and the increasing number of infectious disease for which no vaccine exists has prompted the development of new immunogens. Synthetic peptides based on the determinants of protein antigens can be used as immunogens and offer improvements over traditional preparations. However, peptides alone are usuall...
