Human Type I Diabetes Peripheral Blood Mononuclear Cells

Description

Human Type 1 Diabetes Peripheral Blood Mononuclear Cells (PBMCs) are isolated from patients with type 1 diabetes (T1D), an autoimmune disease characterized by the immune-mediated destruction of insulin-producing pancreatic β cells. These PBMCs exhibit distinct metabolic and functional abnormalities that reflect the disease pathogenesis. The cells show altered expression of genes involved in lipid metabolism and mitochondrial function, along with increased markers of oxidative stress such as lipid peroxidation products. When exposed to inflammatory cytokines like TNF-α or elevated fatty acids, T1D PBMCs demonstrate impaired mitochondrial respiration and ATP production. Immunologically, these cells are characterized by a proinflammatory profile with Th1/Th17 polarization, reduced regulatory T cell function, and heightened sensitivity to inflammatory stimuli. These pathological features reflect the intertwined autoimmune and metabolic dysfunction underlying type 1 diabetes, making T1D PBMCs valuable for investigating disease mechanisms and therapeutic strategies targeting immune–metabolic interactions. In translational research, these samples are widely used to analyze adaptive immune responses and perform integrated PBMC profiling to study disease onset and progression in type 1 diabetes.
