Elsa’s main goal is to characterize the regulatory pathways involved in brain cholesterol homeostasis, and therefore provide a basis for the development of therapeutic approaches for diseases that stretch from genetic disorders, such as Niemann Pick Type C, to neurodegenerative disorders such as Alzheimer’s Disease. Her focus has been on the potential beneficial modulation of cholesterol homeostasis through ectopic expression or pharmacological up-regulation/activation of neuronal specific cholesterol 24-hydroxylase encoded by the cytochrome P450 CYP46A1 gene. Moreover, she has been focusing in the discovery of transcriptional regulators that can modulate neuronal cholesterol levels and in the different cellular players involved in this response.
