C. Non –immune mechanisms • glomerular hypertension • hyperlipidemia (LDL- Cho) • advanced glycosylation end products (protein) glomerulosclerosis
Inflammation Mediators of inflammation A group of molecules which act as mediators of inflammation and complicated biological function Origin of inflammation mediators in kidney Extrinsic Cells in kidney infiltrative neutrophil, lymphocyte, mononuclear macrophage, platelet Intrinsic cells in kidney Mesangial cells, tubular cells, endothelial cells
Inflammation • Mediators of inflammation – A group of molecules which act as mediators of inflammation and complicated biological function • Origin of inflammation mediators in kidney – Extrinsic Cells in kidney • infiltrative neutrophil, lymphocyte, mononuclear macrophage , platelet – Intrinsic cells in kidney • Mesangial cells, tubular cells, endothelial cells
Mediators of inflammation active oxygen and active nitrogen lipids complements cytokines chemotatic factors adhesion molecules growth factors vasoactive substances
Mediators of inflammation - active oxygen and active nitrogen - lipids - complements - cytokines - chemotatic factors - adhesion molecules - growth factors - vasoactive substances
Effects of the inflammation mediators To arouse or promote proliferation of cells accumulation of extracellular matrix changes of histological structure expression of immunomodulating molecules and adhension molecules
To arouse or promote - proliferation of cells - accumulation of extracellular matrix - changes of histological structure - expression of immunomodulating molecules and adhension molecules Effects of the inflammation mediators
