BACKGROUND A recent study demonstrated that an increased number of CD68+ macrophages were correlated with primary treatment failure, shortened progression-free survival (PFS) and disease-specific survival (DSS) in patients with classical Hodgkin's lymphoma (cHL). PATIENTS AND METHODS The aim of the present study was to verify the relationship between the number of CD68+ and CD163+ macrophages...

UNLABELLED Classical Hodgkin lymphoma (CHL) is a B-cell lymphoproliferative disorder with a relatively good prognosis. A small but significant percentage of patients, however, will respond poorly to therapy. A recent gene expression profiling study has identified a macrophage signature which has been correlated with primary treatment failure, and immunohistochemical tissue microarray for CD68 w...

The recruitment of monocytes and their differentiation into macrophages at sites of inflammation are key events in determining the outcome of the inflammatory response and initiating the return to tissue homeostasis. To study monocyte trafficking and macrophage differentiation in vivo, we have generated a novel transgenic reporter mouse expressing a green fluorescent protein (GFP) under the con...

Biological and histopathological techniques identified osteoclasts macrophages as targets of zoledronic acid (ZA), a therapeutic agent that was detrimental for patients in the French OS2006 trial. Conventional multiplex immunohistochemistry microenvironmental OS cells were performed on biopsies 124 17 surgical (“OSNew”) respectively. CSF-1R (common osteoclast/macrophage progenitor) TRAP (osteoc...

OBJECTIVES To investigate the specificity of three anti-CD68 monoclonal antibodies (mAbs) for macrophages (Mphi) in immunohistochemistry (IHC) and flow cytometry (FACS). METHODS IHC was performed on cryostat sections of rheumatoid arthritis (RA) and osteoarthritis (OA) synovial membranes using the anti-CD68 mAbs KP1, EBM11, and PGM1, and the fibroblast (FB) markers CD90 and prolyl 4-hydroxyla...

BACKGROUND Classical Hodgkin's lymphoma is characterized by a minority of neoplastic cells surrounded by a heterogeneous background population of non-neoplastic cells including lymphoma-associated macrophages. High levels of expression of both the monocyte/macrophage lineage-associated antigens CD68 and CD163 have been suggested to have pro-tumor effects. The aim of our study was to correlate e...

PURPOSE To compare the inflammatory profile of hip synovial tissue in those with atraumatic microinstability to patients with femoroacetabular impingement (FAI). METHODS Patients with cam and mixed-type FAI (FAI group) and patients with hip instability underwent sampling of the anterolateral synovium. Demographic data, intraoperative measurements, and functional outcome scores (International ...

Murine macrosialin (MS), a scavenger receptor family member, is a heavily glycosylated transmembrane protein expressed predominantly in macrophage late endosomes. MS is also found on the cell surface where it is suggested, on the basis of ligand blotting, to bind oxidized LDL (oxLDL). Here we report on the regulation of MS by an atherogenic high-fat diet and oxLDL, and on the inability of MS in...

Objective(s): Occludin is essential for proper assembly of tight junctions (TJs) which regulate paracellular endothelial permeability. Omega-3 polyunsaturated fatty acids (Ω-3 PUFA) protect endothelial barrier function against injury. Materials and Methods: We examined anti-inflammatory effect of Ω-3 PUFA intake (30 mg/kg/day for 10 days) on expression and location of occludin in the aorta of ...
