Dipeptidyl Peptidase-4 Inhibitor

In the United States, nearly 13% of adults aged 20 years and older have type 2 diabetes mellitus (T2DM), and its prevalence is still increasing (1,2). Microvascular and macrovascular abnormalities are common in patients with T2DM and are related to the severity and duration of hyperglycemia (3–5). Thus, treatment of hyperglycemia is an important way to prevent or delay diabetic vascular complic...

Dipeptidyl Peptidase 4 Is a Novel Adipokine Potentially Linking Obesity to the Metabolic Syndrome

OBJECTIVE Comprehensive proteomic profiling of the human adipocyte secretome identified dipeptidyl peptidase 4 (DPP4) as a novel adipokine. This study assessed the functional implications of the adipokine DPP4 and its association to the metabolic syndrome. RESEARCH DESIGN AND METHODS Human adipocytes and skeletal and smooth muscle cells were used to monitor DPP4 release and assess the effects...

The Association Between Circulating Klotho and Dipeptidyl Peptidase-4 Activity and Inflammatory Cytokines in Elderly Patients With Alzheimer Disease

Introduction: Klotho and dipeptidyl peptidase-4 (DPP4) are two proteins that modulate inflammatory pathways. We investigated the association between circulating klotho and DPP4 activity and their relationship with inflammatory cytokines, miR-29a, and miR-195 in Alzheimer disease (AD). Methods: This study was conducted on 16 AD patients and 16 healthy age-matched controls. Plasma levels of tumo...

Adipose Dipeptidyl Peptidase-4 and Obesity

OBJECTIVE To study expression of the recently identified adipokine dipeptidyl peptidase-4 (DPP4) in subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) of patients with various BMIs and insulin sensitivities, as well as to assess circulating DPP4 in relation to obesity and insulin sensitivity. RESEARCH DESIGN AND METHODS DPP4 expression was measured in SAT and VAT from 196 sub...
