The protein Srebp2 drives cholesterol formation in prion-infected neuronal cells
Date:11/18/2009

the corresponding protein. If cholesterol concentration is elevated in a healthy cell, Srebp2 remains in its inactive form and does not bind to the sterol regulatory element. This control mechanism is obviously disturbed in the infected cells, causing increased cholesterol synthesis. "Remarkably, only neuronal cells react in this way microglia cells exposed to prions do not increase their cholesterol production," said Professor Hermann Schtzl of the Institute of Virology of Technische Universitt Mnchen, who led the research together with Dr. Ina Vorberg. Further studies shall elucidate what role disturbed cholesterol regulation plays in neuronal cells for the development of prion diseases and shall thus point the way to new therapy approaches.
