Severe periodontitis is known to aggravate diabetes mellitus, though molecular events related to that link have not been fully elucidated. Porphyromonas gingivalis, a major pathogen of periodontitis, expresses dipeptidyl peptidase 4 (DPP4), which is involved in regulation of blood glucose levels by cleaving incretins in humans. We examined the enzymatic characteristics of DPP4 from P. gingivalis as well as two other periodontopathic bacteria, Tannerella forsythia and Prevotella intermedia, and determined whether it is capable of regulating blood glucose levels...

Type 2- diabetes mellitus (T2DM) represents a major risk factor for cardiovascular complications and mortality. Strict glucose control in the early course of the disease prevents cardiovascular complications only in the long run. Non-medical therapies (diet, exercise, body weight reduction) bear little evidence for positive cardiovascular effects.Bariatric surgery is not number one choice in therapy of T2DM. Metformin seems to provide positive cardiovascular effects. Insulin seems to be cardiovascular neutral, as well as the DPP4-inhibitors Saxagliptin, Sitagliptin and Alogliptin...

Type 1 diabetes is a chronic organ-specific autoimmune disease in which selective destruction of insulin-producing β-cells leads to impaired glucose metabolism and its attendant complications. A series of Dipeptidyl peptidase 4 (DPP4) inhibitors have been developed and granted approval in the treatment of type 2 diabetes mellitus by inhibiting the enzymatic degradation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP). An increasing number of studies have shown the potential benefits of DPP4 inhibitors for type 1 diabetes...

BACKGROUND: Kidney transplantation is the preferred form of kidney replacement therapy for patients with end-stage kidney disease (ESKD) and is often complicated by worsening or new-onset diabetes. Management of hyperglycaemia is important to reduce post-transplant and diabetes-related complications. The safety and efficacy of glucose-lowering agents after kidney transplantation is largely unknown. OBJECTIVES: To evaluate the efficacy and safety of pharmacological interventions for lowering glucose levels in patients who have undergone kidney transplantation and have diabetes...

Dipeptidyl peptidase 4 (DPP4) is an adipokine that interrupts insulin signaling. The resulting insulin resistance exacerbates hepatic steatosis. We previously reported that the novel DPP4 inhibitor evogliptin improves insulin resistance. This study aimed to verify the therapeutic potential of evogliptin for fatty liver. Evogliptin treatment was initiated simultaneously with a high-fat diet (HFD) feeding in normal mice and in a post-24 week HFD-fed rats. In a prevention study, insulin sensitivity was preserved in evogliptin-treated mice after a 16-week treatment...

BACKGROUND: Adiponectin, an adipose-specific protein, is negatively correlated with pro-atherogenic low-density lipoprotein cholesterol (LDL-C) and other cardiovascular risk factors such as insulin resistance. Therefore, low levels of adiponectin are associated with a higher risk for diabetes and cardiovascular disease. Dipeptidyl peptidase-4 inhibitors (DPP4i) have been used for the treatment of type 2 diabetes mellitus (T2DM) as reversible inhibitors through interacting with DPP4 substrate and increase serum incretins such as glucagon-like peptide-1 (GLP-1)...

BACKGROUND AND AIM: The number of patients with type 2 diabetes (T2DM) is increasing. Most patients with T2DM are uncontrolled and fail to achieve their target Hba1c. In recent years, newer agents such as SGLT2 inhibitors (SGLT2i) have been approved for clinical use. Though data from clinical trials and sub set analysis of Indian patients in global studies are promising, real world evidence from standard clinical practice in India is lacking. The aim of this study was to analyze the metabolic parameters in patients with T2DM on SGLT2i in real world clinical practice...

REVIEW

Gliptins are accepted as a standard therapy for diabetes mellitus today. By inhibition of the enzyme dipeptidyl peptidase 4 (DPP4), gliptins prolong the GLP1-dependent insulin secretion in the pancreatic β-cells and thus support physiological blood glucose control. Various studies have now raised hope for an additional protective effect of pharmacological DPP4 inhibition in vascular diseases. Besides GLP1, especially, the inhibition of SDF1 cleavage has been shown to depict a relevant mechanism to enhance endothelial regeneration and reduce atherosclerosis progression via the SDF1-CXCR4 axis...

BACKGROUND: Parkinson's disease is a chronic neurodegenerative disorder characterized by a progressive loss of dopaminergic neurons. The pathophysiological mechanisms underlying Parkinson's are still unknown. Mitochondrial dysfunction, abnormal protein aggregation, increased neuroinflammation and impairment of brain glucose metabolism are shared processes among insulinresistance, diabetes and neurodegeneration and have been suggested as key mechanisms in development of Parkinson's and cognitive impairment...

OBJECTIVE: Cardiac function was markedly compromised in obese insulin-resistant and estrogen-deprived rats. Metformin and dipeptidyl peptidase-4 inhibitor (vildagliptin) were reported to improve cardiac function in insulin-resistant rats. Their effects on the heart under estrogen-deprived conditions are, however, unknown. Therefore, the effects of metformin, vildagliptin, and estrogen on the cardiac function in estrogen-deprived insulin-resistant female rats were investigated. METHODS: Bilateral ovariectomized female rats (n = 48) were divided to be fed with either a normal diet (ND) or a high-fat diet (HFD) for 12 weeks...

We conducted a pilot study to evaluate two therapeutic strategies at the time of insulin initiation in type 2 diabetic patients insufficiently controlled with metformin+insulin-secretagogues (IS, sulfonylureas or glinides). Patients were randomized to remain under the same dual therapy or to receive metformin+DPP4 inhibitors while starting insulin. Similar glycemic control was achieved in both groups. However less hypoglycemia was observed with DPP4 inhibitors despite higher doses of insulin.

BACKGROUND: Both sodium glucose cotransporter 2 (SGLT2) inhibitors and dipeptidyl peptidase-4 (DPP4) inhibitors can be used to treat patients with type 2 diabetes mellitus (T2DM) that is inadequately controlled with insulin therapy, and yet there has been no direct comparison of these two inhibitors. METHODS: We searched MEDLINE, EMBASE, LILACS, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov through June 2015. Randomized controlled trials published in English that compare SGLT2 inhibitor plus insulin (SGLT2i/INS) with placebo plus insulin or DPP4 inhibitor plus insulin (DPP4i/INS) with placebo plus insulin in patients with T2DM were selected...

Oral delivery of proteins is still a challenge in the pharmaceutical field. Nanoparticles are among the most promising carrier systems for the oral delivery of proteins by increasing their oral bioavailability. However, most of the existent data regarding nanosystems for oral protein delivery is from in vitro studies, lacking in vivo experiments to evaluate the efficacy of these systems. Herein, a multifunctional composite system, tailored by droplet microfluidics, was used for dual delivery of glucagon like peptide-1 (GLP-1) and dipeptidyl peptidase-4 inhibitor (iDPP4) in vivo...

Glucagon-like peptide-1 (GLP-1), an incretin hormone, is used for type 2 diabetes mellitus (T2DM) treatment because of its ability to stimulate insulin secretion and release in a glucose-dependent manner. Despite of its potent insulinotropic effect, oral GLP-1 delivery is greatly limited by its instability in the gastrointestinal tract, poor absorption efficiency and rapid degradation by dipeptidylpeptidase-4 (DPP4) enzyme leading to a short half-life (~2min). Thus, a multistage dual-drug delivery nanosystem was developed to deliver GLP-1 and DPP4 inhibitor simultaneously...
