Introduction type 1 diabetes mellitus is a chronic immune-mediated disease resulting from selective destruction of insulin producing beta-cells.
Type 1 diabetes (t1d) is a chronic inflammatory disease that develops when the body’s immune system mistakenly attacks the cells that make insulin (called ‘beta cells’) insulin allows the body to use energy from food and helps control blood sugar levels, and without it the body cannot function properly currently, t1d is treated by life-long. Type 1 diabetes is a genetic autoimmune disorder caused by autoreactive cd4+ and cd8+ t-cells that recognize pancreatic antigens such as insulin or gad and subsequently destroy insulin-producing β-cells the subject of very active research is the question of how endogenous β-cell antigens become immunogenic.

Figure 1 healthy islet (a) and an islet in a patient with chronic type 1 diabetes (b) stained with anti-insulin antibody.
Type 1 diabetes (t1d) is a chronic autoimmune disease in which destruction or damaging of the beta-cells in the islets of langerhans results in insulin deficiency and hyperglycemia we only know for sure that autoimmunity is the predominant effector mechanism of t1d, but may not be its primary cause t1d precipitates in genetically.
