A CD4+ human T cell clone YN5-32 recognized a streptococcal M12p54-68 peptide in the context of HLA-DR4 and produced a large amount of IFN-y. We investigated responses of YN5-32 to 156 independent analogue peptides carrying single residue substitutions at residues 57 (position 1 (PI)) to 65 (p9) of the peptide. Approximately 30% of analogues at either Leu5’ (pl), Ala6’ (*), or As@ (p6) residues...
Neurokinin 1 receptors (NK1R) are overexpressed on several types of important human cancer cells. Substance P (SP) is the most specific endogenous ligand known for NK1Rs. Accordingly, a new SP analogue was synthesized and evaluated for detection of NK1R positive tumors. [6-hydrazinopyridine-3-carboxylic acid (HYNIC)-Tyr8-Met(O)11-SP] was synthesized and radiolabeled with 99mTc using ethylenedia...
گلوتامین مهمترین و غالبترین اسیدآمینه موجوددرخون میباشدکه یک منبع آمینواسیدی آزاددرعضلات اسکلتی بوده و در بدن به عنوان منبع مهم انرژی عمل می کند.در تمرینات شدیدو طولانی مدت سطح گلوتامین پلاسما کاهش می یابدو نشانه هایی از تغییرات در متابولیسم گلوکز و هورمونهای متابولیکی مربوطه مشاهده می گردد که میتواند باعث ضعف,خستگی و نهایتاتحلیل عضلانی در ورزشکاران شود.جهت بررسی تاثیر مصرف مکمل گلوتامین بر سطح...
AIM The relationship between genetic polymorphisms of the glucagon-like peptide-1 (GLP-1) receptor (GLP1R) gene and unresponsiveness to GLP-1 analogue treatment in patients with poorly controlled type 2 diabetes mellitus (DM) is unclear. METHODS Thirty-six patients with poorly controlled type 2 DM were enrolled and they received six days of continuous subcutaneous insulin infusion for this st...
Somatostatin, a peptide present in hypothalamus, gastric mucosa, and pancreas suppresses several gastrointestinal functions. Its short half life has prevented clinical use. We have therefore evaluated the effect of subcutaneous administration of a new synthetic somatostatin analogue, in comparison with a placebo, on pentagastrin stimulated acid secretion in six healthy volunteers. On different ...
background and objective : due to the evolution of multidrug-resistant strains, screening of natural resources, especially actinomycetes, for new therapeutic agents discovery has become the interests of researchers. in this study, molecular, chemical and biological screening of soil actinomycetes was carried out in order to search for peptide-producing actinomycetes. materials and methods : 60 ...
The effect of introducing D-amino acid residues in an hexapeptide was examined both at the antigenic and immunogenic levels. A series of D-analogues of the model peptide of sequence IRGERA corresponding to the COOH-terminal residues 130-135 of histone H3 were produced. Four analogues contained a single change of an L-residue by the corresponding enantiomer, one peptide contained two D-residues ...
