Información del artículo
En los últimos años, gracias en parte a la utilización de las modernas técnicas de análisis diferencial de la expresión génica, se han identificado potenciales dianas terapéuticas para la arteriosclerosis. Algunas de ellas son factores de transcripción que regulan vías metabólicas en el hígado. De este tipo son los receptores nucleares LXR (liver X receptor) y FXR (farnesol X receptor), aunque no sólo actúan en el hígado, sino que también están presentes en las células vasculares y en los monocitos/macrófagos donde regulan mecanismos clave para la aterogénesis. Estos y otros receptores nucleares que se han identificado recientemente en la pared vascular constituyen una prometedora área de investigación, al tratarse de factores de transcripción implicados en muchos de los procesos asociados a la aterogénesis y porque, al ser activados por ligandos, son dianas ideales para su modulación farmacológica.

Dianas terapéuticas
In the last few years, partly due to the use of modern techniques for differential analysis of gene expression, potential therapeutic targets for arteriosclerosis have been identified. Some of these are transcription factors that regulate metabolic pathways in the liver. Among this type are the nuclear receptors LXR (Liver X receptor) and FXR (Farnesol X receptor), although these nuclear receptors not only act in the liver but are also present in vascular cells and in monocytes/macrophages where they regulate key mechanisms for atherogenesis. These and other nuclear receptors that have recently been identified in the vascular wall constitute a promising field of investigation, as they are involved in many of the processes associated with atherogenesis. Furthermore, because they are activated by ligands, they are ideal targets for its pharmacological modification.
