Activity of Dipeptidyl Peptidase-IV/CD26 and Aminopeptidase N/CD13 in Secretome of Mesenchymal Stem Cells after Treatment with LPS and PMA
Background: Emerging evidence suggests that secretome of mesenchymal stem cells has many anti-inflammatory and regenerative properties, which makes it a suitable candidate for the treatment of autoimmune and degenerative diseases. Dipeptidyl Peptidase-IV (DPP-IV)/CD26 and Aminopeptidase N (APN)/CD13 are ubiquitous ecto-enzymes which can digest various substrates including some ...
متن کاملCD26-mediated signaling for T cell activation occurs in lipid rafts through its association with CD45RO.
CD26 is a T cell activation antigen that contains dipeptidyl peptidase IV activity and is known to bind adenosine deaminase. The mechanism by which CD26 costimulation potentiates T cell receptor-mediated T cell activation, leading to subsequent exertion of T cell effector function, is still not clearly defined. In this article, we demonstrate that CD26 localizes into lipid rafts, and targeting ...
متن کاملAutomatic Recognition of Muscle-invasive T-lymphocytes Expressing Dipeptidyl-peptidase IV (CD26) and Analysis of the Associated Cell Surface Phenotypes
A neural cell detection system (NCDS) for the automatic quantitation of fluorescent lymphocytes in tissue sections was used to analyze CD26 expression in muscle-invasive T-cells. CD26 is a cell surface dipeptidyl-peptidase IV (DPP IV) involved in co-stimulatory activation of T-cells and also in adhesive events. The NCDS system acquires visual knowledge from a set of training cell image patches ...
متن کاملGlycosaminoglycans Regulate CXCR3 Ligands at Distinct Levels: Protection against Processing by Dipeptidyl Peptidase IV/CD26 and Interference with Receptor Signaling
CXC chemokine ligand (CXCL)9, CXCL10 and CXCL11 direct chemotaxis of mainly T cells and NK cells through activation of their common CXC chemokine receptor (CXCR)3. They are inactivated upon NH₂-terminal cleavage by dipeptidyl peptidase IV/CD26. In the present study, we found that different glycosaminoglycans (GAGs) protect the CXCR3 ligands against proteolytic processing by CD26 without directl...
متن کاملDipeptidyl peptidase IV (DDP IV) in NASH patients.
OBJECTIVE(S) Non-alcoholic steatohepatitis (NASH) is a chronic liver disease with unknown etiology. The insulin resistance, immune mechanisms and oxidative stress are the main factors in its pathogenesis. Dipeptidyl peptidase IV (DPPIV) or CD26 is a protein with endocrine and immune functions. This study aimed to elicudate the changes related to DPPIV in NASH patients. METHODS Serum and urina...
