BACKGROUND Prostate cancer is one of the most common cancer types both in western and eastern countries, involving mostly elder men. The mechanisms underlying the prostate cancer development remain unclear. Prostate-specific antigen (PSA) is the only well accepted marker for prostate cancer diagnosis and prognosis. The diagnosis and treatment of prostate cancer are facing big challenges. Here, ...
CD26 is a M(r) 110,000 surface glycoprotein with diverse functional properties, including having a potentially significant role in tumor development, and antibodies to CD26 mediate pleomorphic cellular functions. In this report, we show that binding of soluble anti-CD26 monoclonal Ab 1F7 inhibits the growth of the human CD30+ anaplastic large cell T-cell lymphoma cell line Karpas 299 in both in...
110-kDa glycoprotein that is expressed on numerous cell types and has multiple biological functions. A key facet of CD26/DPPIV biology is its enzymatic activity and its physical and functional interaction with other molecules. The substrates of CD26/DPPIV are proline-containing peptides and include growth factors, chemokines, neuropeptides, and vasoactive peptides. DPPIV plays an important role...
The CD26-associated enzymatic activity of dipeptidyl peptidase-4 (DPP4) as well as the recruitment of CD26(+) T cells increase under allergic airway inflammation. Furthermore, genetic deficiency of CD26/DPP4 exerts protective effects in experimental asthma. Therefore, CD26/DPP4 might represent a novel therapeutic target in asthma. To study the effects of pharmacological inhibition of DPP4 on al...
The serum mannan-binding protein (MBP) is a host defense C-type lectin specific for mannose, N-acetylglucosamine, and fucose residues, and exhibits growth inhibitory activity toward human colorectal carcinoma cells. The MBP-ligand oligosaccharides (MLO) isolated from a human colorectal carcinoma cell line, SW1116, are large, multiantennary N-glycans with highly fucosylated polylactosamine-type ...
Hematopoietic stem cells (HSCs) are responsible for maintaining all blood cells throughout the lifetime of an individual, and are used clinically to treat various malignant and nonmalignant disorders. However, for some HSC grafts, for instance from umbilical cord blood (UCB), limited numbers of HSCs restrict their application to pediatric patients. Expanding HSCs in vitro or improving their hom...
The mouse lymphoid organ-resident CD8alpha(+) dendritic cell (DC) subset is specialized in Ag presentation to CD8(+) T cells. Recent evidence shows that mouse nonlymphoid tissue CD103(+) DCs and human blood DC Ag 3(+) DCs share similarities with CD8alpha(+) DCs. We address here whether the organization of DC subsets is conserved across mammals in terms of gene expression signatures, phenotypic ...
This issue of the journal focuses on flow cytometric detection Sézary syndrome (SS) and mycosis fungoides (MF) in peripheral blood (PB). As outlined editorial (Craig, 2021), cytometry has been used since early 1980's to immunophenotype SS MF, characteristic CD7-negative, CD26-negative was readily adopted by dermatology groups. However, there is frustration among both clinicians cytometrists. se...
CD26/DPPIV is a multifunctional cell surface protein that is widely expressed in most cell types including T lymphocytes, on which it is a marker of activation. It is also present in serum and other body fluids in a truncated form (sCD26/DPPIV). It preferentially cleaves N-terminal dipeptides from polypeptides with proline or alanine in the penultimate position, and in doing so, regulates the a...
