Background:
Diabetes mellitus type-1 is an immunological disease associated with low insulin release and hyperglycemia due to beta cell loss. No clear studies show the relationship between the coagulation cascade activation and diabetes mellitus type-1 development.
Objective:
The present work aimed to clarify the function of the active coagulation system in the progression of diabetes mellitus type-1 (T1DM). Furthermore, the possible protective action of direct thrombin inhibitors (dabigatran) against T1DM caused by streptozotocin (STZ)-induced T1DM in mice model was examined.
Materials And Methods:
Forty Balb/c male albino mice were distributed into four different groups, with 10 mice in each group: normal, dabigatran (DAB)-treated, STZtreated, and STZ+DAB. Blood glucose, blood platelets, serum insulin, nuclear consistency, and pancreas histopathological changes were evaluated. Moreover, the expressions of PI3K, p-Akt, insulin, and fibrinogen were investigated in the pancreatic tissues via immunofluorescent technique.
Results:
The findings displayed enhanced islet expression of fibrinogen, p-Akt, and PI3K proteins along with thrombocytopenia in STZ-injected mice when equated to control. Furthermore, treatment with STZ reduced pancreatic insulin expression. DAB and STZ-cotreatment significantly diminished pancreatic tissue expression of fibrinogen, PI3K, and p-AKT, as well as increased platelet counts and pancreatic insulin expression.
Conclusion:
The evidence supported the activation of coagulation cascade in T1DM through the PI3K/AKT pathway. Using direct antithrombin therapy may open new avenues for T1DM prevention in high-risk diabetes individuals.
Insights
Coagulation cascade activation is linked to type-1 diabetes development via the PI3K/AKT pathway. Direct thrombin inhibitors like dabigatran show potential in preventing type-1 diabetes in high-risk individuals.
Area of Science:
- Immunology
- Hematology
- Endocrinology
Background:
- Type-1 diabetes (T1DM) is an autoimmune disease characterized by insulin deficiency and hyperglycemia.
- The relationship between coagulation cascade activation and T1DM development is not well-established.
Purpose of the Study:
- To investigate the role of the coagulation system in T1DM progression.
- To evaluate the protective effects of dabigatran, a direct thrombin inhibitor, in a mouse model of streptozotocin (STZ)-induced T1DM.
Main Methods:
- Mice were divided into four groups: control, dabigatran-treated, STZ-treated, and STZ + dabigatran.
- Evaluated parameters included blood glucose, platelets, serum insulin, and pancreatic histopathology.
- Investigated protein expressions (PI3K, p-Akt, insulin, fibrinogen) in pancreatic tissues using immunofluorescence.
Main Results:
- STZ-induced T1DM mice showed increased fibrinogen, PI3K, and p-Akt expression, and thrombocytopenia.
- STZ treatment reduced pancreatic insulin levels.
- Dabigatran co-treatment normalized fibrinogen, PI3K, and p-Akt levels, increased platelet counts, and restored insulin expression.
Conclusions:
- Coagulation cascade activation, mediated by the PI3K/AKT pathway, contributes to T1DM.
- Direct antithrombin therapy, such as dabigatran, may offer a novel strategy for T1DM prevention in at-risk populations.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
