Objective The aim of this study was to investigate two enkephalin-degrading enzymes, aminopeptidase N (APN/CD13) and endopeptidase (NEP/CD10), gene and protein expression levels in sperm samples of fertile and heroin-addicted men, and the correlation between their expressions and semen quality. MaterialsAndMethods This case-control study, semen collected from 24 normozoospermic healthy (as a co...

Phenotypic changes in neutrophil granulocytes (NG) after G-CSF have been scarcely studied. Using flow cytometry, we analyzed the changes of CD11b, CD14, CD33, CD71, HLA-DR, CD10, CD16 and CD15 on NG after G-CSF treatment in 6 patients with ALL receiving intensification chemotherapy and in 10 control subjects. After G-CSF we found: expression of HLA-DR, a higher expression of CD11b, CD71 and CD1...

human liver. Representative images of claudin-1 costained with markers specific for apical (CD10) or basolateral (cytokeratin 8) membranes. Heterogeneous patterns of claudin-1 at apical and basolateral membranes were observed. Magnified volumetric images (white box) prepared using Imaris software demonstrate claudin-1 localization around CD10, in keeping with a pericanalicular tight junction di...

A 72 year old woman presented with swelling of the right lobe of her thyroid gland. Fine needle aspiration and flow cytometry showed a clonal population of B cells expressing CD10 and a diagnosis of follicle centre cell lymphoma was made. Subsequent excision of the thyroid showed the typical histological features of a marginal zone non-Hodgkin lymphoma. Polymerase chain reaction showed no evide...

We describe a rare intraosseous myoepithelioma, arising in a rib. The patient was a 14-year-old female. The tumor, composed of epitheliod cells and plump spindle cells, was immunopositive for AE1/AE3, S-100 protein, HHF-35, desmin, smooth muscle actin (SMA), CD10, and c-kit, indicating a diagnosis of myoepithelioma. The tumor had invaded surrounding soft tissues, indicating a locally aggressive...

We present the first reported case of papillary cystadenofibroma of the epididymis. The tumor occurred in a 46-year-old man. The mass was 3.7 cm and included a hemorrhagic fluid-filled cyst. Microscopically, stromal-filled papillae were lined by low cuboidal to columnar epithelium. Epithelial cells were reactive for cytokeratin 7, cytokeratins AE1/3, and focally in the apical cytoplasm for CD10...

C D26, the T cell activation molecule, is a 110-kD gly-coprotein that is also present on epithelial cells of various tissues, including the liver, kidney, and intestine. CD26 possesses a known dipeptidyl peptidase (DPP)IV activity in its extracellular domain (1). A paper by Wesley et al. in this issue indicates a possible role for CD26/DPPIV in suppressing malignant transformation of melanocyte...
