Objective:
The aim of this study was to explore the efficacy of insulin-loaded trimethylchitosan nanoparticles on certain destructive effects of diabetes type one.
Materials And Methods:
Twenty-five male Wistar rats were randomly divided into three control groups (n=5) and two treatment groups (n=5). The control groups included normal diabetic rats without treatment and diabetic rats treated with the nanoparticles. The treatment groups included diabetic rats treated with the insulin-loaded trimethylchitosan nanoparticles and the diabetic rats treated with trade insulin. The experiment period was eight weeks and the rats were treated for the last two weeks.
Result:
The livers of the rats receiving both forms of insulin showed less severe microvascular steatosis and fatty degeneration, and ameliorated blood glucose, serum biomarkers, and oxidant/antioxidant parameters with no significant differences. The gene expression of pyruvate kinase could be compensated by both the treatment protocols and the new coated form of insulin could not significantly influence the gene expression of glucokinase (p<0.05). The result of the present study showed the potency of the nanoparticle form of insulin to attenuate hyperglycemia, oxidative stress, and inflammation in diabetes, which indicate the bioavailability of insulin-encapsulated trimethylchitosan nanoparticles.
Insights
Insulin-loaded trimethylchitosan nanoparticles effectively reduced diabetes complications in rats, showing potential for treating type one diabetes. This novel nanoparticle delivery system demonstrates significant bioavailability and therapeutic efficacy.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Endocrinology
Background:
- Diabetes mellitus type one is a chronic condition requiring lifelong insulin therapy.
- Conventional insulin delivery methods face challenges with bioavailability and stability.
- Nanoparticle-based drug delivery systems offer potential for improved therapeutic outcomes.
Purpose of the Study:
- To evaluate the efficacy of insulin-loaded trimethylchitosan nanoparticles.
- To assess the impact of these nanoparticles on diabetes-related complications.
- To compare nanoparticle insulin with conventional insulin treatment.
Main Methods:
- Twenty-five male Wistar rats were used, divided into control and treatment groups.
- Treatment involved either insulin-loaded trimethylchitosan nanoparticles or trade insulin over two weeks.
- Key parameters including blood glucose, biomarkers, and gene expression were analyzed.
Main Results:
- Both insulin treatments reduced liver steatosis and fatty degeneration.
- Amelioration of blood glucose, serum biomarkers, and oxidant/antioxidant parameters was observed.
- Insulin nanoparticles showed potency in attenuating hyperglycemia, oxidative stress, and inflammation, indicating bioavailability.
Conclusions:
- Insulin-loaded trimethylchitosan nanoparticles are effective in mitigating destructive effects of type one diabetes.
- The nanoparticle formulation demonstrates significant bioavailability and therapeutic potential.
- This approach offers a promising alternative for insulin delivery in diabetes management.
