Neuroscientist
Isabelle M. Mansuy (born
December 5 ,
1965 in
Cornimont , France) is a professor in
neuroepigenetics in the Medical Faculty of the
University of Zurich and the Department of Health Science and Technology of the
Swiss Federal Institute of Technology Zurich . She is known for her work on the mechanisms of
epigenetic inheritance in relation to
childhood trauma .
[1]
[2]
Education and career
Mansuy studied molecular biology and biotechnology at the
University Louis Pasteur and the
École Supérieure de Biotechnologie de Strasbourg .
[3] Mansuy went on to earn a PhD at the
Friedrich Miescher Institute in Basel
[4] then a postdoc at
Columbia University , where she gained expertise in
neurobiology and in the design and use of transgenic mouse models. She established a lab as assistant professor at
ETH Zürich at the end of 1998 and a few years later became professor in neuroepigenetics at the University of Zürich and ETH Zürich.
[5]
Research
Mansuy initially worked on the molecular mechanisms of memory using mouse models.
[6] Her team revealed the specific molecules that allow the adult brain to forget through constraining memory formation and storage. It identified
protein phosphatase 1 (PP1) and
calcineurin as such molecular suppressors and demonstrated that these molecules need to be inhibited through training to relieve their suppressing action on neuronal activity necessary for memorisation. Her team was also able to demonstrate the detrimental effects of the excess of these molecules in the diseased and aged brain, highlighting their link to memory deficits and cognitive decline in aging. Another important finding was that PP1 is a key epigenetic regulator in neurons that controls the
post-translational modification of
histones and therefore genome activity. The role of such an enzyme in epigenetic regulation in relation to cognitive processes was not known before, these findings participated to found the new field of neuroepigenetics that emerged in late 2000, and opened unexpected therapeutic perspectives linking the epigenome to memory diseases.

[9]
Mansuy's current research examines the
epigenetic basis of complex brain functions and physiological changes in mammals with a focus on the mechanisms of epigenetic inheritance.
[10]
[1]
[11] The goal is to determine how life experiences can influence mental and physical health across generations and what molecular mechanisms are involved. The research is focused on how adverse experiences in early life can lead to psychiatric and metabolic disorders. Mouse models and cellular systems are used to study
non-coding RNAs , epigenetic factors and
chromatin remodelling in the brain and germline, and elucidate how they are involved in the expression and subsequent transmission of environmentally-induced
phenotypes .
[5] Her lab showed that the effects of traumatic stress in early life can be transmitted across multiple generations in mice
[12]
[13] and that RNA in sperm is a vector of transmission.
[14] Recent work showed that blood factors are involved in transmission mechanisms
[15] and have been validated in human subjects.
