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 کاملOrgan distribution of aminopeptidase A and dipeptidyl peptidase IV in normal mice.
The hydrolases aminopeptidase A and dipeptidyl peptidase IV, both present in the kidney on the brush borders of the proximal tubule epithelial cells and podocytes, are involved in the induction of experimental membranous glomerulonephritis in the mouse. However, little is known about their (co)distribution in other tissues and their function in health and disease. A detailed insight into the lo...
متن کاملDistribution of proline-specific aminopeptidases in human tissues and body fluids.
The proline-specific peptidases, aminopeptidase P (EC 3.4.11.9) and dipeptidyl peptidase IV (EC 3.4.14.5), were measured in human tissue homogenates and physiological fluids. All tissues examined contained measurable aminopeptidase P and dipeptidyl peptidase IV activities. High specific activities for both enzymes under study were found in benign prostatic hypertrophy. Normal prostate and prost...
متن کاملDipeptidyl peptidase IV in angiotensin-converting enzyme inhibitor associated angioedema.
Angioedema is a potentially life-threatening adverse effect of angiotensin-converting enzyme inhibitors. Bradykinin and substance P, substrates of angiotensin-converting enzyme, increase vascular permeability and cause tissue edema in animals. Studies indicate that amino-terminal degradation of these peptides, by aminopeptidase P and dipeptidyl peptidase IV, may be impaired in individuals with ...
متن کاملInterspecies differences in membrane-associated protease activities of thyrocytes and their relevance for thyroid cancer studies
BACKGROUND To understand the role of proteases involved in human thyroid cancer progression and tissue invasion, thyrocytes from other species could potentially be used provided their characteristics are similar. It is not known whether dipeptidyl peptidase IV and aminopeptidase N activities, which are overexpressed in human thyroid cancer, are, as in human, also absent in normal thyrocytes of ...
