Hyperglycemia is primary directly of diabetic complications, but it effects are not lifed tte te klomemulus.

Inflamation

Chronic low-grade entremation is a hallmark of diabetes. Hyperglycemia stimulates tubulaur cells to produce pro-efficinatory cytokines such as interleukin-1β (IL-1β), tumor necrosis faktor-α (TNF-α), and monocyte chemoactant protein-1 (MCP-1). These cytokines recurit macrophages and T-cells into the interstitium, leading to an matory cascade that tubulages cells and promotes fibro.

Oxidative Stres

High intracellular glucose drops excessive mitochondrial production of reactive oxygen species (ROS). In tubular cells, superoksyde anion, hydrogen peroxyde, and hydroksyl radicals damage lipids, proteins, and DNA. Oxidative stres also activates the cription factor hypoxia-inducible factor-1α (HIF-1α) paradoxically, leading to maladaptiva responses. Antioksydant enzymes such as superoxide dismote (SOD) and catale are downdulates in. in.

Fibrozy

Interstitial fibronectin - the pathological acculation of extracellular matrix proteins like kolagen I, III, fibronectin, and tenascin - is final pathway of progressive kidney disease. Transforming growth factor-β1 (TGF-β1) is the master profibrozic cytokine. In the diabetic tulointerstitium, TGF-β1 is upregulated by hyperglycemia, AGs, and angiotensin I. It promotes epiblial-tlo-t- mesenchenchymal transin (EMT), myofiblastion, and depositin of antifibroxatic.

Hipoxia

Tubular cells have a high metabolic and are superitarly loweblones to oxygen deprywation. In diabetes, microvascular rarefaction - thee loss of otrzewnej kapillaries - reducles oxygen delivy to thee tubulointerstitium. Simultanously, succed tubulaar workload (due to hyperfiltration and high glucosuria) elevates oksygen consumption.
