Complete transcriptomic characterization of islets in patients with type 2 diabetes mellitus has yet to be completed, and it remains challenging to link insulin secretion dysfunction with precise changes in gene expression. There are several ongoing initiatives aimed at enabling the discovery of regulatory molecules that might contribute to insulin secretion dysfunction and whole-body glucose homeostasis impairment. In one such line of research, Bacos <i>et al</i>.<span><sup>1</sup></span> obtained evidence suggesting that the gene <i>PAX5</i> might play an important role in impaired insulin secretion in human islets (Figure 1).</p><p>Given the established differences between mouse and human islets, type 2 diabetes mellitus candidate genes that were identified in mice might not have the same regulative effects on human islets. There is an unmet need for powerful transcriptomic analyses that can be applied to human islets isolated from individuals with type 2 diabetes mellitus and nondiabetic controls. Due to the difficulties associated with obtaining human islets, most human islet transcriptomic studies thus far have involved small cohorts and have lacked functional validation. Bacos <i>et al</i>.<span><sup>1</sup></span> generated a ribonucleic acid sequencing (RNA-Seq) resource bank from the large Lund University Diabetes Center pancreatic islet cohort. It is one of the largest existing type 2 diabetes mellitus human islet cohorts in existence, providing an extensive gene expression resource based on 309 islet preparations in total from individuals with type 2 diabetes mellitus and nondiabetic controls.

There remains a need to analyze human islets from a more diverse donor pool, and larger cohorts to clarify whether islet gene expression differs among individuals with type 2 diabetes mellitus in relation to demographic and pathophysiological variables.

PAD pathology involves atherosclerosis and impaired immunity. Non-classical monocytes are believed to have an anti-inflammatory role. 1,25-Dihydroxy vitamin D (vitamin D<sub>3</sub>) is claimed to have immune-modulating and lipid-regulating roles. Vitamin D receptor is expressed on monocytes. We aimed to investigate if circulating non-classical monocytes and vitamin D<sub>3</sub> were implicated in DFUs associated with PAD.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials and Methods</h3>\u0000 \u0000 <p>There were two groups of DFU patients: group 1 (<i>n</i> = 40) included patients with first-degree DFUs not associated with PAD, and group 2 (<i>n</i> = 50) included patients with DFU with PAD. The monocyte phenotypes were detected using flow cytometry. Vitamin D<sub>3</sub> was assessed by enzyme-linked immunosorbent assay.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>DFU patients with PAD showed a significant reduction in the frequency of non-classical monocytes and vitamin D<sub>3</sub> levels, when compared with DFU patients without PAD. The percentage of non-classical monocytes positively correlated with vitamin D<sub>3</sub> level (<i>r</i> = 0.4, <i>P</i> &lt; 0.01) and high-density lipoprotein (<i>r</i> = 0.5, <i>P</i> &lt; 0.001), whereas it was negatively correlated with cholesterol (<i>r</i> = −0.5, <i>P</i> &lt; 0.001). Vitamin D<sub>3</sub> was negatively correlated with triglyceride/high-density lipoprotein (<i>r</i> = −0.4, <i>P</i> &lt; 0.01). Regression analysis showed that a high vitamin D<sub>3</sub> serum level was a protective factor against PAD occurrence.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Non-classical monocytes frequency and vitamin D<sub>3</sub> levels were significantly reduced in DFU patients with PAD. Non-classical monocytes frequency was associated with vitamin D<sub>3</sub> in DFUs patients, and both parameters were linked to lipid profile. Vitamin D<sub>3</sub> upregulation was a risk-reducing factor for PAD occurrence.</p>\u0000 </section>\u0000 </div>","PeriodicalId":190,"journal":{"name":"Journal of Diabetes Investigation","volume":"14 10","pages":"1192-1201"},"PeriodicalIF":3.2,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jdi.14048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41081848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
