Colorectal cancer may be maintained by cancer stem-like cells (CSCs) that express the cell surface marker CD133. CSCs (CD133+cells) exhibits greater resistance to the chemotherapy and this resistance may be mediated in part by an autocrine response to IL4.The aim of the study was to assess the effect of anti-IL4 antibody alone or in combination with chemotherapy on the CD133 expression andthe tumor...
Tumor necrosis factor-α (TNF-α) is a cytokine involved in the various physiopathological processes such as autoimmune disorders and inflammation related diseases. Some multidrug resistant (MDR) cancer cell lines including MCF-7/MX are more vulnerable to cytotoxic effects of TNF-α than their parental lines. In this study, breast cancer cell line MCF-7 and its MDR derivative MCF-7/MX were exposed to...
Lumbar radicular pain after disc herniation may be associated with release of pro-inflammatory cytokines from nucleus pulposus (NP) tissue. In the present study we examined the role of interferon-γ (IFN-γ) and cluster of differentiation 68 (CD68) in the acute phase of this process.First, in an animal model mimicking the clinical situation after disc herniation, the role of IFN-γ close to the dorsal...
To compare the temporal release (over three weeks) of tumor necrosis factor alpha (TNF-α), interleukin 4 (IL-4), IL-1 receptor antagonist (IL-1ra), platelet-derived growth factor BB (PDGF-BB) and transforming growth factor beta-1 (TGF-β1) from two platelet-rich fibrin (PRF) preparations from equine blood obtained at either 240g/8min or 416g/10min.Whole blood from 10 horses was used to obtain PRF clots...
Rheumatoid arthritis (RA) is a destructive and chronic autoimmune inflammatory disease. Synovial inflammation is a major feature of RA and is associated with leukocyte recruitment. Leukocytes cross the endothelial cells (ECs) into the synovial tissue and fluid and this migration is mediated via a range of chemokines and adhesion molecules on the ECs. As important mediators of leukocyte extravasation,...
