    Abstract A 52-year-old Japanese woman developed type 1 diabetes mellitus (type 1 DM) at 41 years old. She became complicated with Hashimoto's disease and showed swelling of both submandibular glands, which was diagnosed as IgG4-related disease (IgG4-RD). This is a rare case of a Japanese patient with autoimmune polyglandular syndrome type 3A (APS-3A) coexisting with autoimmune thyroid disease (AITD) and type 1 DM complicated by IgG4-RD. Bilateral submandibular gland resection was successfully performed without steroid therapy. We discuss the possibility that the immunological pathogenic mechanisms of APS-3A and IgG4-RD are related.

    Abstract Clinical success of immune-checkpoint blockade (ICB) cancer immunotherapy is compromised by increased risk of immune-related adverse events (irAEs). However, mechanistic action(s) of immune responses underlying development of irAE remain not fully explored. Here, we found that in tumor-bearing aged, but not young, mice, antiprogrammed death receptor (PD)-1 therapy elicited irAE-like multiorgan dysfunctions with ectopic accumulation of T and B cells in damaged organs. In this preclinical model, the organ toxicities were mediated by immunoglobulin G (IgG) deposition because administration of IG from ICB-treated aged mice induced the pathogenicity specifically in naïve aged hosts. Mechanistically, CD4 T-cell-derived interleukin (IL)-21 upregulated B-cell-homing chemokine, CXCL13, preferentially in irAE organs from aged mice treated with anti-PD-1 therapy. The ICB-induced pathogenicity was alleviated by B-cell depletion or by blockade of IL-21 or CXCL13 activity. These results suggest that age-associated immune regulatory milieu contributes to the formation of tertiary lymphoid structure-like lymphocytic aggregates in irAE organs and irAE-related toxicity employing IL-21-CXCL13-auto-antibody axis. Supporting this, a systemic increase in CXCL13 and

    Abstract The role of the renin-angiotensin-aldosterone system (RAAS) on the development of insulin resistance and type 2 diabetes (T2DM) is an area of growing interest. Most of the deleterious actions of the RAAS on insulin signals appear to be mediated through activation of the serine/threonine kinase, oxidative stress and tissue-inflammation in insulin-sensitive organs. Both experimental and clinical studies demonstrated that angiotensin II (Ang II) and aldosterone could play a role in the development of insulin resistance, diabetes and cardiovascular diseases. Large randomized clinical trials revealed that blockade of the RAAS with either angiotensin I converting enzyme inhibitors or AT1 receptor blockers results in decreased T2DM incidence, with a minor attenuation of markers for insulin resistance. This review focuses on the role of RAAS in the pathogenesis of insulin resistance, as well as on clinical relevance of RAAS blockade in the prevention and treatment of the metabolic syndrome and pre-diabetes.

    Abstract The gastrointestinal tract is considered an important endocrine organ for controlling glucose homeostasis via the production of incretins. A 21-year-old man emergently underwent total colectomy due to severe ulcerative colitis, and overt diabetes became evident. Weekly administration of a glucagon-like peptide (GLP)-1 receptor agonist (RA) dramatically improved his glucose control. Levels of GLP-1 or gastric inhibitory polypeptide (GIP) were low at the baseline in the duodenum and serum of the patient. After 11 months of GLP-1RA treatment, his HbA1c worsened again, and intensive insulin therapy was necessary to control his glucose levels. Our report may explain the significance of residual incretin for maintaining the pancreatic β-cell function.

    Abstract Acetate kinase catalyzes the reversible magnesium-dependent phosphoryl transfer from ATP to acetate to form acetyl phosphate and ADP. Here, we report functional and some structural properties of cold-adapted psychrotrophic enzyme; acetate kinase with those from mesophilic counterpart in Escherichia coli K-12. Recombinant acetate kinase from Shewanella sp. AS-11 (SAK) and E. coli K-12 (EAK) were purified to homogeneity following affinity chromatography and followed by Super Q column chromatography as reported before [44]. Both purified enzymes are shared some of the common properties such as (similar molecular mass, amino acid sequence and similar optimum pH), but characterized shift in the apparent optimum temperature of specific activity to lower temperature as well as by a lower thermal stability compared with EAK. The functional comparisons reveal that SAK is a cold adapted enzyme, having a higher affinity to acetate than EAK. In the acetyl phosphate and ADP-forming direction, the catalytic efficiency (k(cat)/K(m)) for acetate was 8.0 times higher for SAK than EAK at 10 °C. The activity ratio of SAK to EAK was increased with decreasing temperature in both of the forward and backward reactions. Furthermore, the activation energy, enthalpy and entropy in both reaction directions that catalyzed by SAK were lower than those catalyzed by EAK. The model structure of SAK showed the significantly reduced numbers of salt bridges and cation-pi interactions as compared with EAK. These results suggest that weakening of intramolecular electrostatic interactions of SAK is involved in a more flexible structure which is likely to be responsible for its cold adaptation.

    Abstract Nonalcoholic fatty liver disease (NAFLD) is often accompanied by metabolic disorders such as metabolic syndrome and type 2 diabetes (T2DM). Heat shock response (HSR) is one of the most important homeostatic abilities but is deteriorated by chronic metabolic insults. Heat shock (HS) with an appropriate mild electrical stimulation (MES) activates HSR and improves metabolic abnormalities including insulin resistance, hyperglycemia and inflammation in metabolic disorders. To analyze the effects of HS + MES treatment on NAFLD biomarkers, three cohorts including healthy men (two times/week, n = 10), patients with metabolic syndrome (four times/week, n = 40), and patients with T2DM (n = 100; four times/week (n = 40) and two, four, seven times/week (n = 20 each)) treated with HS + MES were retrospectively analyzed. The healthy subjects showed no significant alterations in NAFLD biomarkers after the treatment. In patients with metabolic syndrome, many of the NAFLD steatosis markers, including fatty liver index, NAFLD-liver fat score, liver/spleen ratio and hepatic steatosis index and NAFLD fibrosis marker, aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio, were improved upon the treatment. In patients with T2DM, all investigated NAFLD steatosis markers were improved and NAFLD fibrosis markers such as the AST/ALT ratio, fibrosis-4 index and NAFLD-fibrosis score were improved upon the treatment. Thus, HS + MES, a physical intervention, may become a novel treatment strategy for NAFLD as well as metabolic disorders.

    Abstract Background and aims: Local macrophage proliferation is linked to enhanced atherosclerosis progression. Our previous study found that troglitazone, a thiazolidinedione (TZD), suppressed oxidized low-density lipoprotein (Ox-LDL)-induced macrophage proliferation. However, its effects and mechanisms are unclear. Therefore, we investigated the effects of pioglitazone, another TZD, on macrophage proliferation.
    Methods: Normal chow (NC)- or high-fat diet (HFD)-fed apolipoprotein E-deficient (Apoe
    Results: Atherosclerosis progression was suppressed in aortic sinuses of pioglitazone-treated Apoe
    Conclusions: Pioglitazone suppressed macrophage proliferation through PPARγ without inducing macrophage apoptosis. These findings imply that pioglitazone could prevent macrovascular complications in diabetic individuals.
