background: there is evidence that mesangial cell structural changes contribute to the pathogenesis of diabetic nephropathy. to gain better insight into the mechanisms responsible for this issue, present study focused on effect of cord blood mononuclear cells (mncs) derived cd133 positive cells on mesangial cell structure and function. materials and methods: the animals were randomly divided in...

Colonic tissue membrane binding to peripheral blood mononuclear leukocytes was quantitated by 1251labeling of membrane fragments and by determining the acquisition of membrane-specific enzyme activity and radioactivity in mononuclear cells after contact with the tissue membrane fragments. Mononuclear cells bound equal amounts of non mal and tumor tissue membrane fragments. Mononuclear cells cap...

BACKGROUND Several mechanisms have been proposed to explain why some platelets have a reduced response to aspirin (ASA). Among them, it was reported an increased circulating level of vitamin-D-binding protein (DBP). In addition, nitric oxide (NO) released from mononuclear cells was involved in the antiplatelet effects of ASA. The aim was to analyse the relationship between platelet response to ...

Abstract Genital mycoplasmosis is a condition present in bovine production systems, and the most important agents involved are Mycoplasma bovis , bovigenitalium Ureaplasma diversum . Some aspects of their pathogenesis remain unclear. This study was designed order to evaluate ability stimulate mononuclear cells from endometrium, vagina peripheral blood cycling healthy cows produce nitric oxide (...

Background Recurrent spontaneous abortion (RSA) is a complication in pregnancy that results into fetus rejection by mother and several factors such as anatomical, genetic and immunological problems can be its etiologic causes. Paternal lymphocyte therapy as an immunotherapy for these patients has been more evaluated. The purpose of lymphocyte therapy is stimulation of the mother immune system t...

Background: Atherosclerosis is a chronic inflammatory disease affecting large and medium arteries. CD4+ T cells are known to play a role in the progression of the disease. CD4+CD25+Foxp3+ natural Treg (nTreg) cells seem to have a protective role in the disease and their reduction in acute coronary syndrome is recently shown. Objective: To investigate the frequency of nTreg subsets in the pe...

Background: Atherosclerosis is a multifactorial disorder with chronic inflammatory conditions in which immune cells play a significant role in its pathogenic process. Regulatory T cells (Treg), as a part of immune system, are involved in controlling autoimmune and inflammatory diseases. Quantitative and/or functional alteration of Tregs has been shown to play an atheroprotective role and may al...

Background: Several biological and medical benefits of Saffron, Crocus sativus (Iridaceae), have been demonstrated. However, mechanisms of actions for purified constituents are greatly unknown. Objective: To examine the effects of Safranal, a main constituent of Saffron stigma, on cell viability and cytokine profile of peripheral blood mononuclear cells (PBMC) were examined. Methods: Effect...

The expression of c-sis proto-oncogene in bronchoalveolar mononuclear cells was studied in seven patients with pulmonary sarcoidosis. By means of nuclear run on transcription assay, the transcriptional level of c-sis proto-oncogene in bronchoalveolar mononuclear cells was investigated. Expression of c-sis proto-oncogene in bronchoalveolar mononuclear cells was enhanced. Enhancement of c-sis tra...

Determination of magnesium in mononuclear blood cells may provide useful information about intracellular magnesium. Mononuclear blood cell preparations are frequently contaminated with granulocytes. We determined the normal reference interval for magnesium content and concentration of granulocytes and compared it with magnesium in mononuclear blood cells. The mean granulocyte magnesium concentr...
