Abstract
Background A growing number of studies found inconsistent results on the role of chemokines in the progression of type 2 diabetes (T2DM) and prediabetes (PDM). The purpose of this meta-analysis was to summarize the results of previous studies on the association between the chemokines system and T2DM/PDM. Methods We searched in the databases, PubMed, Web of Science, Embase and Cochrane Library, for eligible studies published not later than March 1, 2020. Data extraction was performed independently by 2 reviewers, on a standardized, prepiloted form. Group differences in chemokines concentrations were summarized using the standardized mean difference (SMD) with a 95% confidence interval (CI), calculated by performing a meta-analysis using the random-effects model. Results We identified 98 relevant studies that investigated the association between 32 different chemokines and T2DM/PDM. Altogether, these studies involved 14,708 patients and 14,574 controls. Results showed that the concentrations of CCL1, CCL2, CCL4, CCL5, CCL11, CXCL8, CXCL10 and CX3CL1 in the T2DM patients were significantly higher than that in the controls, while no difference in these concentrations was found between the PDM patients and controls. Conclusion Progression of T2DM may be associated with elevated concentrations of chemokines. Meta-Analysis Registration PROSPERO, identifier CRD42019148305.

Abstract
The aim of this study was to determine whether maternal diabetes induced by alloxan injection in the first gestational day of female Wistar rats interferes with the development of the nociceptive peripheral system of the offspring. Behavioral and histologic analysis was performed using the adult offspring of diabetic and control rats. It was found that the offspring of diabetic rats were more sensitive to thermal stimulation and showed an altered response to carrageenan-induced inflammatory hyperalgesia. The histological analysis showed an increased proportion of nociceptive neurons, while the population of non-nociceptive myelinated neurons was reduced. Therefore, exposition to hyperglycemia and/or hyperinsulinemia in uterus, caused by a diabetic mother, might result in altered nociceptive sensations in the offspring throughout life.

Circulating Monocyte and Lymphocyte Populations in Healthy First-Degree Relatives of Type 2 Diabetic Patients at Fasting and during Short-Term Hyperinsulinemia. Mediators Inflamm 2019; 2019:1491083. [PMID: 30983877 PMCID: PMC6432732 DOI: 10.1155/2019/1491083] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2018] [Accepted: 01/27/2019] [Indexed: 12/11/2022] Open
Abstract
Aim The development of type 2 diabetes (T2DM) is associated with disturbances of immune status that may be reflected by alterations of the profile of circulating immune cells. In order to study whether there exists genetic predisposition to these alterations, we investigated the relative content of circulating monocyte and lymphocyte subpopulations at fasting condition and upon stimulation by short-term hyperinsulinemia in nondiabetic first-degree relatives (FDR) of T2DM patients and in control subjects. Materials and Methods 19 nondiabetic (FDR) and 19 control subjects without a family history of diabetes (all men) matched for age and BMI underwent 2-hour hyperinsulinemic-euglycemic clamp. Blood samples taken before and at the end of the clamp were used for the flow cytometry analysis of lymphocyte and monocyte populations and for the assessment of cytokine levels. Results At fasting conditions, FDR showed a higher CD4/CD8 ratio of peripheral lymphocytes, a higher percentage of Th17 lymphocytes, and a lower content of intermediate monocytes when compared to controls. The CD4/CD8 ratio correlated with fat mass, insulin, and HOMA-IR in the entire group of subjects. Hyperinsulinemia decreased a relative content of peripheral CD4+ and increased a relative content of CD8+ T lymphocytes, thus decreasing the CD4/CD8 ratio by 18-22% in both groups of subjects. In FDR but not in controls, the decrease of CD4+ T lymphocyte content was partially based on the decrease of TH2 and TH17 lymphocyte subpopulations. In control subjects but not in FDR, the number of intermediate monocytes has declined in response to hyperinsulinemia. Conclusion The alterations of the CD4/CD8 lymphocyte ratio, relative content of TH17 cells, and intermediate monocytes in FDR are features of genetic predisposition to T2DM and may play a role in pathogenesis of T2DM. Short-term hyperinsulinemia affected mostly the immune cell populations deregulated in FDR subjects, which suggests important interplay between immune system homeostasis and insulin levels.

Abstract
BACKGROUND Fractalkine (FKN) is an inflammatory cytokine that has been shown with increased serum levels in diabetic patients and is considered to contribute to the adipose tissue inflammation by supporting monocyte adhesion to adipocytes which has an important role in the pathogenesis of type 2 diabetes mellitus (T2DM). Our aim was to evaluate the effects of glucose ingestion on the serum fractal - kine levels in healthy subjects with normal glucose tolerance (NGT) and newly diagnosed T2DM patients. METHODS A total of 67 patients were included in this study, and they were divided into NGT (n=34) and T2DM (n=33) groups according to their oral glucose tolerance test (OGTT) results. The serum FKN and C-reactive protein (CRP) levels were measured at 0 and 120 minutes during an OGTT following overnight fasting. RESULTS The 0-minute (basal) and 120-minute OGTT FKN levels were found to be significantly higher in the T2DM group when compared to the NGT group (p=0.012 and p=0.001, respectively). However, no significant differences were observed in terms of the changes in the basal and 120-minute OGTT FKN levels in the T2DM and NGT groups (p=0.433 and p=0.06, respectively). A significant positive correlation was observed between the 120-minute OGTT FKN and glucose levels in the study group consisting of all of the patients (r=0.331, p=0.006). CONCLUSIONS In this study, basal and post-glycemic load FKN levels were found to be higher in newly diagnosed T2DM patients than those with NGT; however, there was no additional change in FKN levels by glycemic load.

Abstract
Background Insulin is involved in a glucose homeostatic regulation and a cellular metabolism via phosphorylation of phosphoinositide 3 kinase (PI3K) pathway and mitogen-activated protein kinase (MAPK) pathway. Hyperinsulinemia reduces insulin sensitivity and is an obvious potential factor affecting airway inflammation in chronic airway diseases. MUC5AC is a major secreted mucin, which plays a critical role in inflammatory response in the respiratory tract. However, the relationship between insulin and MUC5AC expression has not been studied. Objective This study investigated the effect and the brief signaling pathway of high concentration of insulin (HI) on MUC5AC expression in human airway epithelial cell. Methods In NCI-H292 cells and primary cultures of normal nasal epithelial cells, the effect and signaling pathway of HI on MUC5AC expression were investigated using reverse transcriptase-polymerase chain reaction (RT-PCR), real-time PCR, enzyme immunoassay, and immunoblot analysis with several specific inhibitors and small interfering RNA (siRNA). Results HI significantly increased MUC5AC expression and activated PI3K/AKT, extracellular signal-related kinase 1/2 (ERK1/2) and p38 MAPKs. The specific PI3K and AKT inhibitor as well as knockdown of AKT1 and AKT2 by the respective siRNAs significantly blocked HI-mediated expression of MUC5AC. Meanwhile, the specific ERK1/2 MAPK and p38 MAPK inhibitor as well as knockdown of ERK1, ERK2, and p38 MAPK by the respective siRNAs also attenuated HI-induced expression of MUC5AC. Conclusion The results of this study suggest that HI induces MUC5AC expression via PI3K/AKT and MAPK signaling pathways in human airway epithelial cells.

Abstract
IL-6 is a pleiotropic cytokine that participates in normal functions of the immune system, haematopoiesis, metabolism, as well as in the pathogenesis of metabolic and cardiovascular diseases. Both pro- and anti-inflammatory roles of IL-6 have been described, which are distinguished by different cascades of signalling transduction, namely classic and trans-signalling. The present review summarizes the basic principles of IL-6 signalling and discusses its roles in diabetes and associated cardiovascular complications, with emphasis on the different outcomes mediated by the two modes of IL-6 signalling and the value of developing therapeutic strategies to specifically target the deleterious trans-signalling of IL-6.

Abstract
AIMS/HYPOTHESIS Low-grade inflammation is a feature of chronic diseases such as type 2 diabetes and lipodystrophy. It is associated with abdominal adiposity, increased levels of NEFA, hyperinsulinaemia and low adiponectin levels. However, the causal relationship between impaired metabolism and inflammation is not understood. We explored the anti-lipolytic effect of acipimox and insulin on adiponectin and adipocyte-associated cytokines in patients with lipodystrophy. METHODS In a randomised placebo-controlled crossover design using nine patients with non-diabetic, HIV-associated lipodystrophy, we assessed whether (1) overnight administration of a low dose of acipimox and/or (2) insulin-induced suppression of NEFA flux altered circulating plasma levels of adiponectin, IL-18, TNF-α and IL-6 in the basal condition and in a two-stage euglycaemic-hyperinsulinaemic clamp combined with stable isotopes (insulin infusion rates 20 mU m(-2) min(-1) and 50 mU m(-2) min(-1)). RESULTS Insulin decreased plasma NEFA in a dose-dependent manner (p < 0.0001). Acipimox reduced basal plasma NEFAs and plasma NEFAs during the low-dose insulin infusion compared with placebo (p < 0.0001 for acipimox effect). Plasma adiponectin and plasma IL-18 were reduced during both situations where lipolysis was inhibited (p < 0.0001 for acipimox effect; p < 0.0001 and p < 0.05 for insulin effect on plasma adiponectin and plasma IL-18, respectively). In contrast, plasma IL-6 and plasma TNF-α did not change during low NEFA concentrations. CONCLUSIONS/INTERPRETATION Using two different tools to manipulate lipolysis, the present study found that acute inhibition of lipolysis reduces levels of adiponectin and IL-18 in patients with HIV-associated lipodystrophy.

Sixteen plasma markers of inflammation and oxidative stress were measured during OGTT in 54 subjects. Leptin, RBP4, CRP, OPN, ANG, MDC, and MCSF concentrations significantly decreased during OGTT (P<0.05). IL6, IL8, and MCP3 concentrations significantly increased during OGTT (P<0.05). These results provide evidence that glucose ingestion affects systemic inflammation and oxidative stress.

Abstract
BACKGROUND Kinin B1 receptor (B1R) intervenes in a positive feedback loop to amplify and perpetuate the vascular oxidative stress in glucose-fed rats, a model of insulin resistance. This study aims at determining whether B1R blockade could reverse vascular inflammation in this model. METHODS/RESULTS Young male Sprague-Dawley rats were fed with 10% D-glucose or tap water (controls) for 8 weeks, and during the last week, rats were administered the B1R antagonist SSR240612 (10 mg/kg/day, gavage) or the vehicle. The outcome was determined on glycemia, insulinemia, insulin resistance (homeostasis model assessment index), and on protein or mRNA expression of the following target genes in the aorta (by Western blot and real-time quantitative polymerase chain reaction): B1R, endothelial nitric oxide synthase, inducible nitric oxide synthase, macrophage CD68, macrophage/monocyte CD11b, interleukin (IL) -1β, tumor necrosis factor-α, IL-6, macrophage migration inhibitory factor, intercellular adhesion molecule-1, and E-selectin (endothelial adhesion molecule). Data showed increased expression of all these markers in the aorta of glucose-fed rats except endothelial nitric oxide synthase and tumor necrosis factor-α, which were not affected. SSR240612 reversed hyperglycemia, hyperinsulinemia, insulin resistance, and the upregulation of B1R, inducible nitric oxide synthase, macrophage CD68, and CD11b, IL-1β, inter-cellular adhesion molecule-1, macrophage migration inhibitory factor, and E-selectin in glucose-fed rats, yet it had no significant effect on IL-6 and in control rats. CONCLUSIONS Kinin B1R antagonism reversed the upregulation of its own receptor and several pro-inflammatory markers in the aorta of glucose-fed rats. These data provide the first evidence that B1R may contribute to the low-grade vascular inflammation in insulin resistance, an early event in the development of type-2 diabetes.
