Expression of pregnane-X-receptor transcript in peripheral blood mononuclear cells and correlation with MDR1 mRNA.
نویسندگان
چکیده
P-glycoprotein (P-gp) limits bioavailability and accumulation of HIV protease inhibitors (PIs). PIs are ligands for the pregnane-X-receptor (PXR), which regulates P-gp expression. This occurs when ligands activate the receptor, initiating binding to response elements in the MDR1 promoter. PXR also activates cytochrome P4503A4 (CYP3A4) and a correlation between hepatic PXR and CYP3A4 mRNA has been reported. We have examined the relationship between MDR1 and PXR mRNA in peripheral blood cells and demonstrate a significant correlation in 18 volunteers (R2=0.4; P<0.005). PXR was approximately 250-fold lower in peripheral blood mononuclear cells than in liver (1.6+/-1.2 vs 450+/-298; n=6; P<0.01).

Bakground: Multiple sclerosis (MS) is a CD4+ T cell-mediated autoimmune disease affecting the central nervous system (CNS). It was previously believed that Th1 cells were pathogenic T cells in experimental autoimmune encephalomyelitis (EAE). However, the functional role of Th1 cells in EAE has been reconsidered upon the discovery of IL-17- producing T cells which are consider as dominant effect...
