Latest advancements in the development of new therapies for type 1 diabetes.

This study aims to explore new treatments for type 1 diabetes that could serve as an alternative or adjunct to insulin therapy. This is a literature review based on a search of relevant scientific articles in PubMed, Scopus, Google Scholar, and Cochrane Library databases. The scrutiny of publications revealed that the introduction of glucagon-like peptide-1 agonists into insulin therapy can improve disease control and reduce the frequency of hypoglycaemic episodes. While immune therapy is pathogenetically justified, its utility is limited in patients with recent onset of type 1 diabetes. It may, however, find application in prophylaxis in individuals at increased risk of developing this type of diabetes. Concurrently, stem cell therapy is under active investigation in clinical trials and has shown promise in reducing insulin dependence, improving ß-cell function and controlling glucose levels. In addition, stem cells have demonstrated efficacy in treating complications of diabetes such as diabetic nephropathy, peripheral neuropathy and diabetic angiopathy. There is compelling evidence supporting the significant potential of gene-editing technology. Intravenous administration of T-regulatory cells, as one method of cell therapy, shows potential in stabilising the course of diabetes and slowing its progression. However, further research is warranted to confirm efficacy. While gene therapy holds promise, much of its research is currently in the preclinical stage. Further development of innovative therapies for type 1 diabetes has the potential to enhance the quality of life of patients, improve disease control and prevent the development of complications (Fig. 1, Ref. 54). Keywords: diabetes type 1, treatment, cell therapy, insulin, pancreatic ß-cells.

Absence of mutations in the human interferon alpha-2b gene in workers chronically exposed to ionising radiation.

Individuals chronically exposed to low-level ionising radiation (IR) run the risk of harmful and long-term adverse health effects, including gene mutations and cancer development. The search for reliable biomarkers of IR exposure in human population is still of great interest, as they may have a great implementation potential for the surveillance of occupationally exposed individuals. In this context, and considering previous literature, this study aimed to identify mutations in the human interferon alpha-2b (hIFNα-2b) as a potential biomarker of occupational chronic low-dose IR exposure linking low-IR exposure to the effects on haematopoiesis and reduced immunity. The analysis was performed in the genomic DNA of 51 uranium miners and 38 controls from Kazakhstan, and in 21 medical radiology workers and 21 controls from Italy. hIFNα-2b gene mutations were analysed with the real-time polymerase chain reaction (PCR) or Sanger sequencing. However, none of the investigated workers had the hIFNα-2b mutation. This finding highlights the need for further research to identify biomarkers for early detection of health effects associated with chronic low-dose IR exposure.
