Endothelial cells (ECs) are believed to be an important component in the protection from lipopolysaccharide (LPS)-induced endotoxic shock. However, the cellular and molecular mechanism is not well defined. Here, we report that signal transducer and activator of transcription (STAT) 3 is an essential regulator of the antiinflammatory function of ECs in systemic immunity. Because STAT3 deficiency results in early embryonic lethality, we have generated mice with a conditional STAT3 deletion in endothelium (STAT3E−/−). STAT3E−/− mice are healthy and fertile, and isolated ECs initiate normal tube formation in vitro. Conditional endothelial but not organ-specific (i.e., hepatocyte or cardiomyocyte) STAT3 knockout mice show an increased susceptibility to lethality after LPS challenge. The LPS response in STAT3E−/− mice shows exaggerated inflammation and leukocyte infiltration in multiple organs combined with elevated activity of serum alanine aminotransferase and aspartate aminotransferase, indicating organ damage. Concomitantly, proinflammatory cytokines are produced at an exaggerated level and for a prolonged period. This defect cannot be explained by lack of antiinflammatory cytokines, such as interleukin 10 and transforming growth factor β. Instead, we have shown that a soluble activity derived from endothelia and dependent on STAT3 is critical for suppression of interferon γ. These data define STAT3 signaling within endothelia as a critical antiinflammatory mediator and provide new insight to the protective function of ECs in inflammation.

BACKGROUND: Cardiovascular disease (CVD) is one the cause of mortality in patients with type 1 diabetes (T1D). The development of CVD is mainly triggered by atherosclerosis, which is associated with the inflammatory process. AIM: The current study was aimed to investigate the association of Vitamin D level and premature atherosclerosis in adolescents with T1D, mainly through the regulation of various cytokines (interferon-γ [IFN-γ], IL-17, interleukin-10 [IL-10], and transforming growth factor-β1 [TGF-β1]). METHODS: This study was designed as a cross-sectional study involving 40 T1D and 40 healthy control who came to the outpatient clinic, Saiful Anwar Hospital, Malang, Indonesia, within the study period (January 2019-July 2019). RESULTS: Our data demonstrated that the IFN-γ and IL-17 levels were significantly higher (p < 0.001), whereas the TGF-β1 and IL-10 levels were significantly lower (p < 0.001) in T1D group compared with control. Furthermore, T1D also has higher carotid intima-media thickness (cIMT) value and lower flow-mediated dilatation (FMD) value compared to the control group (p < 0.001). Level of 25(OH)D3 was strongly associated with reduced cIMT and elevated FMD (p < 0.005). The direct effect of 25(OH)D3 on cIMT and FMD was higher than the indirect effect of Vitamin D through TGF-β1, IL-10, IL-17, and IFN-γ. The cutoff value of 25(OH)D3 levels for the risk of atherosclerosis was 12.8 ng/dL (sensitivity 85.7% and specificity 86.7%). CONCLUSION: The level of Vitamin D in the T1D group was significantly lower than those in healthy children and Vitamin D deficiency substantially influences the formation of premature atherosclerosis.

Background Yak (Bos grunniens) is an ancient bovine species on the Qinghai-Tibetan Plateau. Due to extremely harsh condition in the plateau, the growth retardation of yaks commonly exist, which can reduce the incomes of herdsman. The gastrointestinal barrier function plays a vital role in the absorption of nutrients and healthy growth. Functional deficiencies of the gastrointestinal barrier may be one of the contributors for yaks with growth retardation. Methods To this end, we compared the growth performance and gastrointestinal barrier function of growth-retarded (GRY) and normal yaks (GNY) based on average daily gain (ADG), serum parameters, tissue slice, real-time PCR, and western blotting, with eight yaks in each group. Results GRY exhibited lower (P < 0.05) average daily gain as compared to GNY. The diamine oxidase, D-lactic acid, and lipopolysaccharide concentrations in the serum of GRY were significantly higher (P < 0.05) than those of GNY. Compared to GNY, the papillae height in the rumen of GRY exhibited lower (P = 0.004). In jejunum, with the exception of higher villus height, width, and surface area in GNY, numerical difference (P = 0.61) was detected between two groups for crypt depth. Both in rumen and jejunum, the mRNA expression of interleukin-1beta in GRY was markedly higher (P < 0.05) than that in GNY, but an opposite trend was found in interleukin-10 expression. Moreover, GRY showed a higher (P < 0.05) tumor necrosis factor-alpha mRNA expression in the rumen. The claudin-1 (CLDN1), occludin (OCLN), and zonula occludens-1 (ZO1) expressions of GRY in rumen and jejunum were significantly down-regulated (P < 0.05) as compared to GNY. The correlation analysis identified that in rumen and jejunum, there was a positive correlation between interleukin-10 and CLDN1, OCLN, and ZO1 mRNA expressions, but the tumor necrosis factor-alpha was negatively correlated with CLDN1, OCLN, and ZO1. In the rumen, the ADG was positively correlated with papillae surface area, and a same relationship between ADG and CLDN1, OCLN, and ZO1 expressions was found. Conclusion The results indicated that the ruminal and jejunal barrier functions of GRY are disrupted as compared to GNY. In addition, our study provides a potential solution for promoting the growth of GRY by enhancing the gastrointestinal barrier function.

The article presents a comparative analysis of the cytokine network in 161 patients with pertussis under the age of 1 year and in 180 patients over the age of 1 year. The studies revealed lower production of immunoregulatory cytokines (interferon-γ and interleukin-2) in patients under the age of 1 year at all stages of the disease and with all variants of pertussis (both mono- and mixed infections). The researchers revealed the relationship between the level of interferon-γ production and the severity of pertussis. They revealed age differences in the interferon-8 production in patients with mixed infection, which can determine clinical features and cause bronchopulmonary complications. The authors demonstrated the features of the dynamics of spontaneous and induced production of interleukin-6 and anti-inflammatory cytokines (interleukin-4, interleukin-10) in children under the age of 1 year; these features can be considered as immunological markers determining the imperfection of the humoral response in patients with pertussis in this age group.

Background: Synthetic nanoparticles are deemed to improve treatment with the least adverse effects. The effect of Selenium Nanoparticles (SeNPs) was reviewed on various pathogenic disorders. In the present project, the role of SeNPs on macrophage responses was assessed. Materials and Methods: SeNPs were prepared synthetically by ascorbic acid. Macrophages (MQs) were cultured and treated with SeNPs in combination with bladder tumor lysate and Bacillus Calmette Guerin (BCG). Other experimental groups include SeNPs + tumor lysate + MQs, BCG, BCG+MQs, and MQs. The mRNA levels of interferon-γ and interleukin-10 were evaluated using the real-time PCR method. Results: Synthetic selenium nanoparticles combined with the tumor lysate upregulated the mRNA level of interferon-γ after 12 and 24 h treatment. Regarding interleukin-10 expression, there were no remarkable differences in all experimental groups. The maximum effect of synthetic SeNPs was observed after 24 h treatment. Conclusion: The optimum effect of synthetic SeNPs presents in a treatment-dependent manner.
