Background: Exercise therapy plays an important role in the prevention and treatment of type 2 diabetes (T2DM). The mechanism of exercise therapy in the improvement of glycolipid metabolism of T2DM is very complex and not completely clear. Summary: Exercise training improves the whole body metabolic health in patients with T2DM, leading to an increase in glycolipid uptake and utilization, improved insulin sensitivity, optimized body mass index, and modulated DNA methylation, etc. Recent findings support that some cytokines such as irisin, osteocalcin, and adiponectin are closely related to exercise and metabolic diseases. This study briefly reviews the physiological mechanisms of exercise therapy in diabetes and the potential role of these cytokines in exercise. Key Messages: More high-quality, targeted, randomized controlled studies are needed urgently, from mechanism study to treatment direction, to provide a more theoretical basis for exercise therapy and to explore new therapeutic targets for diabetes.

Underlying Mechanisms

Perturbations of the composition and function of the gut microbiota have been associated with metabolic disorders including obesity, insulin resistance and type 2 diabetes. Studies on mice have demonstrated several underlying mechanisms including host signalling through bacterial lipopolysaccharides derived from the outer membranes of Gram-negative bacteria, bacterial fermentation of dietary fibres to short-chain fatty acids and bacterial modulation of bile acids. On top of this, an increased permeability of the intestinal epithelium may lead to increased absorption of macromolecules from the intestinal content resulting in systemic immune responses, low-grade inflammation and altered signalling pathways influencing lipid and glucose metabolism. While mechanistic studies on mice collectively support a causal role of the gut microbiota in metabolic diseases, the majority of studies in humans are correlative of nature and thus hinder causal inferences. Importantly, several factors known to influence the risk of type 2 diabetes, e.g. diet and age, have also been linked to alterations in the gut microbiota complicating the interpretation of correlative studies. However, based upon the available evidence, it is hypothesised that the gut microbiota may mediate or modulate the influence of lifestyle factors triggering development of type 2 diabetes. Thus, the aim of this review is to critically discuss the potential role of the gut microbiota in the pathophysiology and pathogenesis of type 2 diabetes.

Neuronal Guidance

: Obesity is associated with an exacerbated synthesis and secretion of several molecules, which culminates in chronic low-grade inflammation and insulin resistance. Such conditions affect molecular and physiological responses of several organs and, if not resolved, predispose to the obese patients to suffer other diseases such as Type 2 diabetes, atherosclerosis, cancer, neural injuries, and cognitive impairments. A microenvironment with an excess of pro-inflammatory cytokines released by different cells, including immune and adipose cells lead to suffer metabolic and non-metabolic diseases during obesity. In this context, the role of neuronal guidance cues named netrin, semaphorin and ephrin is novel. Specifically, the available literature indicates that besides to their classic role as molecules that guide to the axon with its target site, the neuronal guidance cues exhibit immunomodulatory functions from adipose tissue to the neural environment. In the current narrative review, we discuss the participation of the neuronal guidance cues on the physiology and pathophysiology of obesity. We also discuss the feedback loop of the obesity on the netrin, semaphorin and ephrin functions that impair the structure and function of the brain. The integrative view of the neuronal guidance cues can be relevant to design new treatments focused to attenuate metabolic and immune disorders that suffering obese patients, and lead to them to acquire worse diseases such as Type 2 diabetes, atherosclerosis, cancer, and neural injuries.

Intrauterine growth restriction (IUGR) leads to reduced birth weight and the development of metabolic diseases such as Type 2 diabetes in adulthood. Mitochondria dysfunction and oxidative stress are commonly found in key tissues (pancreatic islets, liver, and skeletal muscle) of IUGR individuals. In this review, we explore the role of oxidative stress in IUGR-associated diabetes etiology.

Summary Background: An increase in neopterin concentrations is known in some pathologies due to interferon-gamma (INF-γ) activation. These include viral and bacterial infections, auto immune diseases, metabolic diseases, psychiatric disorders, tissue and organ rejections, and different malignancies. The aim of this study was to evaluate the role of neopterin as a prognostic biomarker in type 2 diabetes, which is a metabolic disease with a high worldwide prevalence. Methods: The study included a total of one hundred thirty-nine individuals including one hundred and six patients admitted to a family medicine outpatient clinic and diagnosed with type 2 diabetes and thirty-three healthy volunteers. Serum neopterin concentrations were measured using the enzyme-linked immunosorbent assay. Results: Serum neopterin levels significantly increased in type 2 diabetes patients, compared to the control group (p<0.00001). Conclusions: Early diagnosis of diabetes and determination of the appropriate therapeutic options are of utmost importance, as diabetes is also associated with other systemic diseases. The risk of developing secondary diseases is high in untreated patients. Our study results suggest that serum neopterin may be a useful biomarker in patients with type 2 diabetes.

It is well established that genetic factors play an important role in the development of both type 2 diabetes mellitus (DM2) and obesity, and that genetically susceptible subjects can develop these metabolic diseases after being exposed to environmental risk factors. Therefore, great efforts have been made to identify genes associated with DM2 and/or obesity. Uncoupling protein 1 (UCP1) is mainly expressed in brown adipose tissue, and acts in thermogenesis, regulation of energy expenditure, and protection against oxidative stress. All these mechanisms are associated with the pathogenesis of DM2 and obesity. Hence, UCP1 is a candidate gene for the development of these disorders. Indeed, several studies have reported that polymorphisms -3826A/G, -1766A/G and -112A/C in the promoter region, Ala64Thr in exon 2 and Met299Leu in exon 5 of UCP1 gene are possibly associated with obesity and/or DM2. However, results are still controversial in different populations. Thus, the aim of this study was to review the role of UCP1 in the development of these metabolic diseases.

Background: DM is a group of metabolic diseases characterized by hyperglycemia that occurs due to abnormal insulin secretion, insulin action, or both. Symptoms that are complained of in diabetes mellitus sufferers are polydipsia, polyuria, polyphagia, weight loss, and tingling sensation. The oral glucose tolerance test is a test used to diagnose DM when the blood glucose level is less firm, during pregnancy, or to screen for DM or TGT. Leptin is a hormone produced by fat cells that regulate fat storage in the body and adjusts hunger to energy expenditure. Objective: to find out more about the role of leptin on TTGO in people with Type 2 diabetes. Methods: using literature studies from both national and international journals to increase knowledge and understanding of the topics discussed by summarizing the discussion topics and comparing the results presented in the article. Results: Leptin on TTGO examination in individuals with impaired glucose tolerance had a greater chance of becoming diabetes mellitus if there was no intervention in their lifestyle. Conclusion: Leptin plays a role in checking TTGO in people with Type 2 diabetes

Gout is the most common inflammatory arthritis in adults and has continued to increase in prevalence over the past decades. Gout is characterized by hyperuricemia with the obligatory crystallization of urates and an associated inflammatory reaction, as well as metabolic effects caused, among other things, by these processes. In particular, the diagnosis of gout is identified with a high risk of carbohydrate metabolism disorders, which is 2 times higher than the population risk: according to various sources, from 21 to 26% of patients with gout have type 2 diabetes mellitus (DM 2). However, the role of uric acid and urate-lowering drugs in its development in patients with gout remains controversial. The possibility of influencing the risk of developing diabetes mellitus type 2 of chronic inflammation, the activity of interleukin-1β and other pro-inflammatory cytokines, hyperuricemia, xanthioxidase and other factors associated with gout is discussed. It is possible that the level of uric acid is associated with diabetes and other metabolic diseases, causing pathophysiological changes not only through inflammation, but also oxidative stress, damage to the vascular endothelium. It is also suggested that gout and DM 2 may share genetic markers. The interrelation of violations of purine and carbohydrate metabolism prompts the search for drugs that have a simultaneous positive effect on purine and carbohydrate metabolism. However, it is not clear what the level of uric acid should be considered as a risk factor, there are conflicting data on the possibility of reducing the risk of developing diabetes with various anti-gout therapies.
