Although treatment of multiple sclerosis (MS) with the type I interferon (IFN) IFN-β lowers disease activity, the role of endogenous type I IFN in MS remains controversial. We studied CD4+ T cells and CD4+ T cell subsets, monocytes and dendritic cells by flow cytometry and analysed the relationship with endogenous type I IFN-like activity, the effect of IFN-β therapy, and clinical and magnetic ...
It has been hypothesized that autism results from an 'opioid peptide excess'. The aims of this study were to (1) confirm the presence of opioid peptides in the urine of children with autism and (2) determine whether dipeptidyl peptidase IV (DPPIV/CD26) is defective in children with autism. Opioid peptides were not detected in either the urine of children with autism (10 children; nine males, on...
This study was conducted to investigate whether a high-fat/high-carbohydrate (HFHC) meal induces an increase in plasma concentrations of glucagon, dipeptidyl peptidase-IV (DPP-IV), and CD26 expression in mononuclear cells (MNC) while reducing insulin, C-peptide, proinsulin, GIP, and GLP-1 concentrations. Ten healthy normal subjects were given either a 910-calorie HFHC meal or an American Heart ...
DPP IV/CD26 contributes to cell signalling by various mechanisms: as a receptor or co-receptor, as a component of a membrane-associated signal transduction complex and by virtue of its exopeptidase activity. The presence of enzymatically active DPP IV in a variety of tissues and in plasma makes it challenging to review clinical consequences of chemokine turnover by DPP IV activity, even more so...
The mouse lymphoid organ-resident CD8alpha(+) dendritic cell (DC) subset is specialized in Ag presentation to CD8(+) T cells. Recent evidence shows that mouse nonlymphoid tissue CD103(+) DCs and human blood DC Ag 3(+) DCs share similarities with CD8alpha(+) DCs. We address here whether the organization of DC subsets is conserved across mammals in terms of gene expression signatures, phenotypic ...
BACKGROUND Papillary thyroid carcinoma (PTC), follicular thyroid adenoma (FTA), and thyroid nodular hyperplasia (TNH) are the most frequent diseases of the thyroid gland. Previous studies described the involvement of dipeptidyl-peptidase IV (DPPIV/CD26) in the development of thyroid neoplasia and proposed it as an additional tool in the diagnosis/prognosis of these diseases. However, very littl...
The tripeptide amide glycyl-prolyl-glycinamide (GPG-amide) is a new antiretroviral drug candidate, but its absorption mechanism is unknown. In this investigation, the transport and metabolism of GPG-amide were studied in a model of the human intestinal epithelium, Caco-2 cell monolayers. The results show that when the tripeptide amide came into contact with the apical enterocyte membrane, it wa...
Aim. To assess external respiration (ER) and its relationship with the activity of enzymes involved in purine metabolism patients acute chronic forms pulmonary tuberculosis (TB). Materials methods. In TB, we assessed adenosine deaminase (ADA)-1, 2 blood serum (eADA), mononuclear cells, neutrophils, concentration ecto-5’-nucleotidase (eNT5E) serum, level CD26 (dipeptidyl peptidase-4, DPPIV) prod...
سابقه و هدف: اختلالات سیستم ایمنی یکی از مشکلات اساسی بیماران دیالیزی است وعدم توازن پاسخهایTh1 و Th2 نقش به سزایی در پیدایش این اختلالات دارد. این سلولها علاوه بر تولید سیتوکاینهای خاص، برخی از مولکولهای کمک محرک نظیر CD26 و CD30 را بطور ترجیحی بیان می نمایند. این مطالعه با هدف تعیین سطح سرمی این مولکولها در بیماران با نارسایی مزمن کلیه (CRF) و بیماران تحت دیالیز انجام گردید. مواد و روشها:...
