Aminopeptidase N (APN)/CD13 is a transmembrane ectopeptidase expressed on a wide variety of cells. However, the precise function of APN/CD13 in tumor cells and the relationship of APN/CD13 to thyroid cancer remain unclear. In our study, we quantified the expression of APN/CD13 and additionally dipeptidyl peptidase IV (DPIV)/CD26 in thyroid carcinoma cell lines and in tissues of patients with th...

The human fibroblast activation protein alpha (FAP alpha) is a M(r) 95,000 cell surface antigen selectively expressed in reactive stromal fibroblasts of epithelial cancers, granulation tissue of healing wounds, and malignant cells of bone and soft tissue sarcomas. Normal adult tissues are generally FAP alpha-, but some fetal mesenchymal tissues transiently express the molecule. Because of its r...

CD26, a M(r) 110,000 surface-bound ectopeptidase with dipeptidyl peptidase IV (DPPIV) activity, has an array of diverse functional properties, with a role in T-cell physiology and the development of certain human cancers. In this study, we report that surface expression of CD26, through its associated DPPIV enzyme activity, enhanced sensitivity of Jurkat T-cell transfectants to G(2)-M arrest in...

DOI: 10.2174/1573394713666170907160734 Abstract: Background: Malignant mesothelioma is a largely incurable disease that is refractory to current therapies. CD26 is a multifunctional cell surface protein involved in autoimmune disease, diabetes, and cancer. It has a role in T cell function, extracellular protein modification, as a prognostic factor for cancer, and as a therapeutic target for mal...

Background: Erythroderma is an inflammatory disorder. It has various differential diagnoses, among which one of the most important is mycosis fungoides. Erythroderma itself can be a challenging disorder. Diagnosis of a mycosis fungoides patient presenting with erythroderma specially requires a careful assessment of the peripheral blood. Studies such as CD markers can lead to a more accurate dia...

The cell surface association between CD26 and adenosine deaminase (ADA) has a costimulatory function during T-cell activation. Several studies have revealed correlations among CD4(+) CD26(+) T-cell depletion, increased serum levels of ADA, and the evolution of human immunodeficiency virus (HIV) infection, implicating CD26 and ADA in HIV disease progression. In this context, we aimed to determin...

Chemokines are small, chemotactic proteins that play a crucial role in leukocyte migration and are, therefore, essential for proper functioning of the immune system. Chemokines exert their chemotactic effect by activation of chemokine receptors, which are G protein-coupled receptors (GPCRs), and interaction with glycosaminoglycans (GAGs). Furthermore, the exact chemokine function is modulated a...
