Gene Therapy - Can it Cure Type 1 Diabetes?

Area of Science:

• Immunology
• Endocrinology
• Biotechnology

Background:

• Type 1 diabetes (T1D) is a prevalent autoimmune disease primarily managed with insulin therapy.
• Existing treatments focus on managing blood glucose but do not address the underlying autoimmune destruction of pancreatic beta cells.

Purpose of the Study:

• To review current advancements in gene therapy for preventing and potentially curing type 1 diabetes.
• To explore gene therapy techniques aimed at regenerating or preserving pancreatic beta cells for improved insulin secretion.

Main Methods:

• A comprehensive literature search was conducted across PubMed, ScienceDirect, and Google Scholar.
• Eight relevant studies focusing on gene therapy for T1D were selected and analyzed.
• The review examined various gene therapy techniques, including viral vector gene transfer, mRNA electroporation, and growth factor gene expression.

Main Results:

• Reviewed studies indicate favorable outcomes for gene therapy in normalizing insulin production.
• Techniques such as transcription factor delivery, insulin-like growth factor gene expression, and combination gene transfer demonstrated beneficial effects.
• Regenerative approaches focused on preserving or creating insulin-producing cells from other cell types.

Conclusions:

• Gene therapy presents a promising avenue for the future treatment and potential cure of type 1 diabetes.
• Further research, particularly in human clinical trials, is needed to validate these findings.
• Successful gene therapy could revolutionize T1D management by addressing the root cause of the disease.
