Introduction: Although the protective effects of 1,25(OH)2D3 on the early stages of atheromatosis process have been investigated, data on its influence on factors implicated in plaque vulnerability are limited. During these stages metalloproteinases MMP-2, MMP-9, their inhibitors TIMP-1,TIMP-2, the RANKL-RANK-OPG system and MCP-1 play a critical role. We aimed to investigate the effect of vitamin D on the expression of the above factors on endothelial cel...

Introduction: Glucocorticoids (GCs) are used in the treatment of chronic inflammatory or autoimmune diseases. However, patients are often resistant to the GC effects. Response to GCs is triggered through glucocorticoid receptor (GR). An important regulator of GR activity is the FKBP5. FKBP5 binds to co-chaperones promoting a conformation with lower cortisol affinity. The number of GRs is another determinant of GC sensitivity; GR expression is regulated by the nuclear ...

Effects of estrogens on endothelial-derived factors implicated in the atheromatic plaque vulnerability-clarification of the molecular mechanisms

Introduction: In the presence of atherogenic plaque, estrogens may be potentially harmful. Among the key vessel wall components in the later stages of atherogenic process are endothelial cells (ECs). During the stages of plaque instability/rupture, metalloproteinases (MMP2 and MMP9), their inhibitors (TIMP2 and TIMP1), RANK, RANKL, OPG, MCP1, lysyl oxidase (LOX), PDGF, and ADAMTS4 play critical role. We aimed to investigate i) the effect of oestrogens on the expression of the ...
