Bullous pemphigoid (BP) is an autoimmune blistering skin disorder. Recently, BP induced by dipeptidyl peptidase-4 (DPP-4) inhibitors has been a concern. Although DPP-4 inhibitors are commonly used in the Asian population because of their safety and efficacy, BP associated with DPP-4 inhibitors is sometimes seen in clinical settings. Here, we report five Japanese cases of BP associated with the ...

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 ...

BACKGROUND Diabetic patients present with an accelerated atherosclerotic process and an increased risk for future cardiovascular events. In addition to the risk imposed by the disease itself, pharmacological treatment adds also a sizable risk, especially if certain classes of antidiabetic drugs are employed. Animal evidence indicates that dipeptidyl peptidase-4 inhibitors have anti-atherosclero...

We performed a review of the literature to determine whether the dipeptidyl peptidase-4 inhibitors (DPP4-I) may have the capability to directly and positively influence diabetic microvascular complications. The literature was scanned to identify experimental and clinical evidence that DPP4-I can ameliorate diabetic microangiopathy. We retrieved articles published between 1 January 1980 and 1 Ma...

The purpose of this study was to investigate the role of dipeptidyl peptidase IV in regulating the effects of 2 of its substrates, neuropeptide Y(1-36) and peptide YY(1-36), on proliferation of and collagen production by preglomerular vascular smooth muscle and glomerular mesangial cells from spontaneously hypertensive and normotensive rats. In cells from hypertensive rats, neuropeptide Y(1-36)...

Dipeptidyl peptidase I is involved in the activation of a number of disease-related proteases by removal of N-terminal prodipeptides. We here report a selective activity-based probe for monitoring dipeptidyl peptidase I activity in whole proteomes as well as in intact cells, without labeling of closely related enzyme family members.

AIMS/INTRODUCTION Dipeptidyl peptidase-4 inhibitors are used for treatment of patients with type 2 diabetes. In addition to glycemic control, these agents showed beneficial effects on lipid metabolism in clinical trials. However, the mechanism underlying the lipid-lowering effect of dipeptidyl peptidase-4 inhibitors remains unclear. Here, we investigated the lipid-lowering efficacy of anaglipti...
