Signalling lymphocytic activation molecule (SLAM, CD150), originally identified as a lymphocyte activation molecule, is now known to be expressed also on mature dendritic cells and on activated monocytes. Importantly, SLAM is distinct from other monocyte activation markers because its expression on monocytes is readily induced in vitro by bacteria derived ligands of Toll-like receptors (TLRs), ...

There are some reports, suggesting that infiltrating macrophages may promote tumour progression in non-Hodgkin's lymphoma (nHL). The aim of the study was an evaluation of macrophages, marked by antibody against CD68 in indolent and aggressive nHL. The study was performed in 65 patients: 50 with nHL and 15 with lymph nodes affected by reactive hyperplasia. Immunohistochemical analyses were perfo...

OBJECTIVE Despite substantial progress in recent years, graft survival beyond the first year still requires improvement. Since modern immunosuppression addresses mainly T-cell activation and proliferation, we studied macrophage infiltration into the allografts of 103 kidney transplant recipients during acute antibody and T-cell mediated rejection. Macrophage infiltration was correlated with bot...

OBJECTIVE The relationship between inflammation, obesity, and adverse metabolic conditions is associated with adipose tissue macrophages (ATM). This study compared the measurements of human ATM using flow cytometry, immunohistochemistry (IHC), and real-time polymerase chain reaction (RT-PCR) of ATM markers. METHODS A new software program (AMCounter) was evaluated to help measure ATM using IHC...

We have previously identified a 94- to 97-kDa oxidized low density lipoprotein (LDL)-binding protein in mouse macrophages as macrosialin (MS), a member of the lamp family. Earlier immunostaining studies have shown that MS and its human homolog, CD68, are predominantly intracellular proteins. However, using sensitive techniques such as flow cytometry (FACS) and cell-surface-specific biotinylatio...

Congenital epulis is a fairly rare soft tissue tumour occurring exclusively on the alveolar ridge of newborns. The exact origin of congenital epulis is still debatable. The objective of the study is to determine the clinicopathological features and immunohistochemical findings of congenital epulis. A retrospective study was carried out to determine the clinicopathological features of congenital...

Undifferentiated pleomorphic sarcoma (UPS) is rare type of soft tissue sarcomas that occur in all parts body but mostly the extremities. Sixty-year-old woman presented dyspnea and stridor with benign looking subglottic mass on laryngoscope. Endoscopic laser surgery was performed histopathology showed diffuse proliferation plump spindle cells no particular orientation to vessels. In immunochemis...

BACKGROUND Decidual vascular development is important for implantation. This study analysed decidual vascular adaptation to implantation in correlation with miscarriage in decidual secretory endometrium (DSE), decidua parietalis (DP) and decidua basalis (DB) of miscarriage patients and matched controls. METHODS Decidua was obtained during first trimester termination of pregnancy (controls) an...

Teeth extracted for orthodontic reasons are commonly considered as healthy. Therefore, it is possible to examine structure of the dental pulp can be fully recognized and how it is affected by malocclusion. The aim of the study was to evaluate by immunohistochemistry (IHC) and morphometry dental pulp in human upper first premolar teeth extracted for orthodontic reasons. The material comprised 36...
