thrombin is a multifunctional enzyme which has key roles in coagulation cascade and inflammatory events. the pro-inflammatory functions of thrombin occur by different mechanisms including increasing mast cell degranulation, up-regulating the expression of cell adhesion molecules (cams) and promoting the secretion of inflammatory chemokines and cytokines. dysregulated signaling functions of thro...

Detrimental immune response has a crucially important role in the development and progression of inflammatory eye diseases. Inflammatory mediators proteolytic enzymes released by activated cells induce serious injury corneal epithelial retinal ganglion cell which may result vision loss. Mesenchymal stem (MSCs) are regulatory produce various immunosuppressive factors that modulate phenotype func...

Inflammation impacts human hematopoiesis across physiologic and pathologic conditions, as signals derived from the bone marrow microenvironment, such pro-inflammatory cytokines chemokines, have been shown to alter hematopoietic stem cell (HSCs) homeostasis. Dysregulated inflammation can skew HSC fate-related decisions, leading aberrant potentially contributing pathogenesis of hematological diso...

Stroke causes neuronal necrosis and generates inflammation. Pro-inflammatory molecules intervene in this process by triggering glial cell activation and leucocyte infiltration to the injured tissue. Cytokines are major mediators of the inflammatory response. Pro-inflammatory and anti-inflammatory cytokines are released in the ischaemic brain. Anti-inflammatory cytokines, such as interleukin-10,...

Background: Similar to inflammatory cells, peripheral blood mononuclear cells (PBMCs) can also infiltrate in to kidney and urinary tracts and subsequently excreted by urine. In this study we determined the viability rate and response to phytohemagglutinin-A (PHA) of human PBMCs in normal urine. Methods: A number of 1×106 ficoll-hypaque isolated PBMCs were dispensed in 1 ml normal urine...

inflammatory bowel disease (ibd) is a chronic inflammatory disease affecting the gastrointestinal tract and includes ulcerative colitis and crohn’s disease. during last decades, the incidence of ibd   has increased, both in children as well as in adults (1–3). while the precise etiology of ibd is unknown, inflammatory bowel disease occure due to an abnormal immune response to luminal antigens i...

controversial immunomodulatory properties of bee venom (bv) have provided an appropriate field for more investigation. the aim of present research was to verify the effects of honeybee venom on matrix metalloproteinase activity and interferon production as well as cell proliferation in monocyte and fibroblast cell lines. the monocyte and fibroblast cell lines (k562, ht-1080, wehi-164) were used...

Objective(s): It is generally believed that the inflammatory response in bone marrow mesenchymal stem cells (BMSCs) transplantation leads to poor survival and unsatisfactory effects, and is mainly mediated by cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α). In this study, we explored the mechanisms underlying the TNF-α-induced inflammatory ...

BACKGROUND Diseases associated with human cartilage, including rheumatoid arthritis (RA) and osteoarthritis (OA) have manifested age, mechanical stresses and inflammation as the leading risk factors. Although inflammatory processes are known to be upregulated upon aging, we sought to gain a molecular understanding of how aging affects the tissue-specific response to inflammation. In this report...
