The specific recognition of foreign peptide bound to the major histocompatibility complex (MHC) molecule by T-cell receptor (TCR) leads to T-cell activation. We found that analogue peptides containing single amino acid substitutions at the third amino acid position (p3), p5, p7 and p8 of the index peptide (YWALEAAAD) induced different response patterns of T cell clones specific for the index pe...
The article presents the synthesis and results of study effect chronic neonatal administration by intranasal method an analogue C-terminal fragment arginine-vasopressin (AVP) - N -Ac- D Met-Pro-Arg-Gly-NH 2 on training level depression in white rats three age groups. It is shown that most significant was manifested test for development conditional reaction active avoidance. A favorable degree a...
In this study, a novel approach for the development of a peptide-based vaccine has been tested. We investigated the possibility of replacing an all-L amino acid peptide sequence corresponding to the protective B-cell epitope hemagglutinin (HA) 91-108 from influenza HA with a retro-inverso analogue encompassing this sequence. Retro-inverso peptides are composed of D-amino acids assembled in a re...
Restricted and high-level expression of interleukin-13 receptor alpha2 (IL-13Ralpha2) in a majority of human malignant gliomas makes this protein an attractive vaccine target. We have previously described the identification of the IL-13Ralpha2(345-353) peptide as a human leukocyte antigen-A2 (HLA-A2)-restricted CTL epitope. However, as it remains unclear how efficiently peptide-based vaccines c...
UNLABELLED The antibiotic streptothricin (ST) possesses an amino sugar bound to an l-β-lysine (β-Lys) residue via a peptide bond. The peptide bond formation has been shown to be catalyzed by a nonribosomal peptide synthetase (NRPS) during ST biosynthesis. The focus of this study is the closely related ST analogue BD-12, which carries a glycine-derived side chain rather than a β-Lys residue. Her...
RP-HPLC of analogues of oxytocin containing a reduced peptide bond was studied using various columns and buffers. Anomalous behavior of one analogue served as a basis for the discussion of possible conformational consequences of this substitution.
Abstract Radiation nephropathy is a rare complication following total body irradiation (TBI) and peptide receptor radionuclide therapy (PRRT). Yttrium 90-dotatoc (Y90) somatostatin analogue labelled with Y90 used for somatostatin-positive neuroendocrine tumours (NET). renally excreted has cumulative effect in the renal parenchyma Despite fractionation co-administration of renoprotective intrave...
background: prostate cancer after lung cancer is the second cause of cancer-associated death in men. in recent years, targeted therapy of cancer has attracted researchers attention. the targeted therapy lead to decrease in side effects of drugs. studies have indicated that targeting peptides for cancer cells represent valuable tools for diagnostic and therapeutic. recently, phage display peptid...
