About me

  • My research is focused on understanding the molecular mechanism behind risk factor for neurodegenerative disorders. From 2017, I combine my activities at KI with being Head of Neurogeneration Research at Sanofi and I am located in Paris (France). So far, I have published 100+ articles and directed 10 PhD thesis.

  • Over the years, genetic and epidemiological studies have reported gene or environmental factors that increase the risk for Alzheimer's Disease (AD), suggesting that it is a disease of multifactorial origin. We aim to contribute to understand the effects of risk factors for AD, and to define to which extent these factors are secondary actors or driving forces for cognitive decline.

    Apolipoprotein E, hypercholesterolemia and AD

    ApoE is the main cholesterol transporter and the presence of the E4 isoform is the major risk factor for AD. High cholesterol levels in blood is another risk factor. Our hypothesis is that ApoE4 acts in synergy with environmental factors (like hypercholesterolemia) to affect signaling pathways involved in neurodegeneration. We use several in vivo and in vitro models to explore this hypothesis.

    Functions of oxysterols in brain

    The metabolism of cholesterol results in the production of several oxysterols, of which the peripherally-produced 27OHC and the brain-produced 24S-OH have been suggested to play a role in AD pathogenesis. However very little is known about the biological role of these oxysterols, with the exception of its affinity for LXR receptors. We have discovered new functions of 24S-OH and 27OHC in brain, related with memory consolidation and vascular regulation. Our findings suggest that these molecules are much more than subproducts of the cellular metabolism, and can be regarded as signalling molecules of importance for normal brain function as well as for neurodegeneration.

    Thioredoxin and AD

    Oxidative stress (OS) is one of the pathological events occurring in AD. Thioredoxin-1 (TRX1) modulate the redox homeostasis and inhibit the apoptosis signal-regulating kinase (ASK1). We reported that the TRX1 levels is impaired in AD. We showed that Abeta neurotoxicity is mediated by TRX1 oxidations and ASK1 activation. Recently, we have described the presence of a truncated form of TRX1 (TRX80) in the brain. TRX80 is dramatically reduced in AD. Also we found that TRX80 as a protective role on Amyloid-beta neurotoxicity and aggregation. So, far TRX80 is the only endogenous anti-Amyloid beta aggregant peptide described.
