Human Type II Diabetes Peripheral Blood Mononuclear Cells

Description

Human Type II Diabetes Mellitus (T2DM) Peripheral Blood Mononuclear Cells (PBMCs) are isolated from patients with this chronic metabolic disorder characterized by insulin resistance and pancreatic β-cell dysfunction. These PBMCs, consisting of lymphocytes (T cells, B cells, NK cells) and monocytes, play a pivotal role in the low-grade chronic inflammation that underlies T2DM pathogenesis. These PBMCs (lymphocytes and monocytes) exhibit proinflammatory activation that drives disease progression. Monocytes differentiate into M1 macrophages secreting TNF-α and IL-6, impairing insulin signaling. T cells show Th1/Th17 skewing (elevated IFN-γ/IL-17) that damages pancreatic β-cells, while Tregs suppression is deficient. NK cell cytotoxicity is altered via ADCC pathways. The cells also demonstrate elevated oxidative stress markers and RAGE expression, reflecting glucolipotoxicity. These immune abnormalities contribute to both systemic insulin resistance and diabetic complications. In translational studies, these PBMCs enable detailed evaluation of the B cell role in type 2 diabetes, comprehensive PBMC phenotyping diabetes, assessment of autoimmune markers in type 2 diabetes, and monitoring of diabetes disease progression across immune and metabolic compartments.
