The recurrence of hypoglycemic episodes leads to attenuation of the normal counter-regulatory mechanisms that are controlled by the hypothalamus, which results in hypoglycemia unawareness (HU). In this case report, we described for the first time the differential expression of TNF-α, IL-1β, IL-6, and IFN-γ in a blood sample that was taken from a 27-year-old patient with type 1 diabetes mellitus (T1DM) who was diagnosed with HU. The anti-diabetic regimen is currently based on insulin injection, but the patient is planning to start the use of an insulin pump to have better control of glucose levels. Our results showed a trend toward an increase in the expression of IL-1β, IL-6, and IFN-γ in T1DM patient with HU. However, the mRNA level of TNF-α showed a significant decrease. These observations suggest that systemic inflammation could be an underlying cause of HU.

AbstractThe methyl-CpG-binding domain 2 (MBD2) interprets DNA methylome-encoded information through binding to the methylated CpG DNA, by which it regulates target gene expression at the transcriptional level. Although derailed DNA methylation has long been recognized to trigger or promote autoimmune responses in type 1 diabetes (T1D), the exact role of MBD2 in T1D pathogenesis, however, remains poorly defined. Herein, we generated an Mbd2 knockout model in the NOD background and found that Mbd2 deficiency exacerbated the development of spontaneous T1D in NOD mice. Adoptive transfer of Mbd2−/− CD4 T cells into NOD.scid mice further confirmed the observation. Mechanistically, Th1 stimulation rendered the Stat1 promoter to undergo a DNA methylation turnover featured by the changes of DNA methylation levels or patterns along with the induction of MBD2 expression, which then bound to the methylated CpG DNA within the Stat1 promoter, by which MBD2 maintains the homeostasis of Th1 program to prevent autoimmunity. As a result, ectopic MBD2 expression alleviated CD4 T cell diabetogenicity following their adoptive transfer into NOD.scid mice. Collectively, our data suggest that MBD2 could be a viable target to develop epigenetic-based therapeutics against T1D in clinical settings.

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.
