Introduction: Monocytes can interact with platelets due to their surface molecules such as P-selectin glycoprotein ligand-1 (PSGL-1), and form monocyte-platelet complex. In the present study, the effects of platelets interaction of platelet concentrates (PCs) and peripheral blood monocytes were investigated in vitro as a model to predict the probable interactions of these cells and consequently...
Introduction: Curcumin is a bright yellow chemical produced by some plants like Turmeric. The anti-inflammatory effects of Curcumin were recorded in some studies. This study was done to investigate the effects of the Curcumin on the physiological functions of rat blood monocytes. Methods: This study was an experimental one. The study population consisted of 20 rats randomly categorized into t...
background: the major immuno-modulating effects of ganoderma lucidum include mitogenicity and activation of immune effector cells such as t cells, macrophages and natural killer cells resulting in the production of cytokines. objective: the purpose of this study was to evaluate the expression of cd40 and cd80 by g. lucidum-treated human peripheral blood mononuclear cells. methods: monocytes wer...
background: the immunomagnetic separation technique is the basis of monocyte isolation and further generation of monocyte-derived dendritic cells. objective: to compare the efficiency of monocyte positive and negative separation, concentration of beads, and their impact on generated dendritic cells. methods: monocytes were obtained using monoclonal antibody-coated magnetic beads followed the fi...
introduction: daphne species has both pharmaceutical applications and anti tumor activity. it has been shown that the extract of daphne mucronata is effective in decreasing the size of breast adenocarcinoma in rats. we investigated the mechanism of action and the effects of the extract on tnf-a and tnf-a receptors on cultured human monocytes. material and methods: the breast tumors were induced...
Background and Objective: Subsequent to spinal cord injury (SCI), many pathological changes may occur that could lead to inappropriate conditions for repair. The most important of such changes include the death of neurons, cyst formation, glial scar, and ineffectiveness of monocytes. Adult stem cells and monocytes may provide new strategies to treat SCI. Among various types of candidate cells, ...
dentin bonding agents (dba) have been used as root-end filling materials. present study evaluated the effects of polymerized dba on secretion of pro-inflammatory cytokines by normal human monocytes. in this study, monocytes were directly isolated from human peripheral blood, and exposed to cured scotch bond 1 (single bond) and prime and bond for 36 and 72 hours. secretion of il-1β and tnf-α in ...
Background and purpose: Circulating monocytes are divided into different subpopulations according to the expression of CD14 and CD16. In this study, we investigated the correlation between the severity of coronary artery disease (CAD) and the frequency of two monocyte subsets and also expression level of CCR1 receptor on these monocytes. Materials and methods: The study was conducted in 88 p...
Background: The immunomagnetic separation technique is the basis of monocyte isolation and further generation of monocyte-derived dendritic cells. Objective: To compare the efficiency of monocyte positive and negative separation, concentration of beads, and their impact on generated dendritic cells. Methods: Monocytes were obtained using monoclonal antibody-coated magnetic beads followed the Fi...
background: recent studies have shown the immunomodulatory effect of vitamin d3 through down-regulation of toll-like receptor (tlr) expression in human monocytes. in this study, the effects of vitamin d treatment on tlr2 and tlr4 expression on monocytes derived from type 2 diabetes was investigated. materials and methods: to assess the influence of vitamin d3 on expression of tlr2 and tlr4 on m...
