ATHEROMA FORMATION

 

Potential Mechanism by which oxidized forms of LDL (oxLDL) may be Atherogenic

- Products of oxLDL are chemotactic for circulating monocyte, T- lymphocyte and inhibit the motility of macrophage.

- Are Cytotoxic

- Can alter genes expression of neighboring arterial walls

- More susceptible to aggregation enhanced Macropage uptake

- Can adversely alter coagulation pathways

- Can induce proinflamatry bens and their products
