Why Inflamation Is Central to Type 2 Diabetes

Type 2 diabetetes, presenting 90- 95 percent of all diabetes cases, is fundamentally an dispaminaory disorder. The process begins with insulin resistance, where cells fail to respond approvately to insulin. Adipose tissue - especially visceral fat - becomes a major source of provimatory cytokines like tumor necrosis factoroalpha (TNF- α), interleukin- 6 (IL6), and resististin. These cytokines dirupt insulin signaln pathalway els promote cell intratio intratio.

Inflamation Fuels Stroke Risk in Diabetes

Inflammation plays a direct role in the pathogenesis of ischemic stroke. Thee process starts with atherosclerosis, a condition defined by lipid- rich plaques acculating with in arterial walls. In diabetes, chronic mation akcelerates each stage of atherogenesia - frem endophelial activation and monocyte recritment to foam cell formation and fibroos cap weakening.

Aterosclerosis andd Plaque Instability

Promusmatory cytokines such as IL- 1β andd TNF- α upregulate adhelion introlules (including VCAM- 1 and ICAM- 1) on endobhelial cells, enabling circulating leukocytes to adhere and migrate into the intima. Once inside, macrophages engulf oksyzed low- density lipoprotein (LDLl) and transform into foam cells.

Key Molecular Mediators Linking Inflammation to Stroke in Diabetes

Several photmomatory biomarkers and pathways have been identified that connect diabetes-driven photomation to elevated stroke risk.
