BACKGROUND
The results of recent studies suggest that dipeptidyl-peptidase-4 inhibitors have antiatherogenic effects. However, whether or not dipeptidyl-peptidase-4 inhibitors could suppress arterial inflammation and intimal hyperplasia after injury remains undetermined. The present study aims to
Several lines of evidence suggest that neuropeptide Y (NPY) may exert regulatory effects in local inflammatory responses. Here, we show that intraplantarly (i.pl.) applied NPY, peptide YY (PYY), and an NPY Y5 receptor-selective agonist dose-dependently potentiate concanavalin A (Con A)-induced paw
BACKGROUND
The peptide neurotransmitter N-Acetylaspartylglutamate (NAAG) is the third most prevalent transmitter in the mammalian central nervous system. Local, intrathecal and systemic administration of inhibitors of enzymes that inactivate NAAG decrease responses to inflammatory pain in rat
This study was designed to compare the efficacy and safety of seaprose S and serratio-peptidase in the treatment of venous inflammatory disease. Forty patients entered the study (11 males, 29 females), mean age 54.3 years (range 30-77), mean weight 74.8 kg (range 51-96), with superficial
Current pathogenic concepts of inflammatory demyelinating disorders such as multiple sclerosis (MS) are based on the hypothesis that a T cell-mediated autoimmune response is involved in the disease process. One of the primary goals in the in the development of immunotherapies for autoimmune diseases
BACKGROUND
Metabotropic glutamate receptors (mGluRs) have been identified as significant analgesic targets. Systemic treatments with inhibitors of the enzymes that inactivate the peptide transmitter N-acetylaspartylglutamate (NAAG), an mGluR3 agonist, have an analgesia-like effect in rat models of
Background: Cellular peptidases are an emerging target of novel pharmacological strategies in inflammatory diseases and cancer. In this context, the dipeptidyl peptidases 8 and 9 (DPP8/9) have gained special attention due to their
Circulating dipeptidyl peptidase IV (DPPIV) activity correlates with cardiac dysfunction in humans and experimental heart failure (HF) models. Similarly, inflammatory markers are associated with poorer outcomes in HF patients. However, the contributions of DPPIV to inflammation in HF remain elusive.
OBJECTIVE
Evaluate the effects of two dipeptidyl peptidase-IV (DPP-4) inhibitors, sitagliptin and vildagliptin, known to have different efficacy on mean amplitude of glycemic excursions (MAGE), on oxidative stress, and on systemic inflammatory markers in patients with type 2 diabetes.
METHODS
A
Dipeptidyl peptidase 4 (DPP4) inhibitors have been widely used in the treatment of type 2 diabetes mellitus. It is well known that DPP4 inhibitors exert their antidiabetes effects mainly by inhibiting the enzymatic degradation of glucagon-like peptide-1 and glucose-dependent insulinotropic peptide.
BACKGROUND
Hypertension induces cardiac dysfunction, calcium (Ca(2+)) dysregulation, and arrhythmogenesis. Dipeptidyl peptidase (DPP)-4 inhibitors, an antidiabetic agent with anti-inflammation and anti-hypertension potential, may regulate peroxisome proliferator-activated receptors (PPARs)-α, -γ,
The nonsteroidal anti-inflammatory drug zomepirac (ZP) is metabolised to a chemically reactive acyl glucuronide conjugate (ZAG) which can form covalent adducts with proteins. In vivo, such adducts could initiate immune or toxic responses. In rats given ZP, the major band detected in liver
Neuropeptide Y (NPY)-induced modulation of the immune and inflammatory responses is regulated by tissue-specific expression of different receptor subtypes (Y1-Y6) and the activity of the enzyme dipeptidyl peptidase 4 (DP4, CD26) which terminates the action of NPY on Y1 receptor subtype. The present
The ectoenzymes dipeptidyl peptidase IV (DP IV, CD26) and aminopeptidase N (APN, CD13) have been implicated in the regulation of T cell activation and function. Both DP IV and APN serve as targets of efficient enzymatic inhibitors which induce autocrine production of TGF-beta1 and subsequent
Inflammatory bowel diseases (Crohn's disease, ulcerative colitis, undetermined colitis) are a group of chronic autoimmune inflammatory diseases distinguished by recurrent inflammation of various parts of the gastrointestinal (GI) system and presenting a significant public health problem. Despite
