The 27th Neuronal Plasticity Prize of the Fondation IPSEN Has Been Awarded to David Attwell, Pierre Magistretti and Marcus Raichle
The 27th annual Neuronal Plasticity Prize of the Fondation
IPSEN will be awarded to three leading scientists for their pioneering
work in the field of neuroenergetics: David Attwell (University
College London, UK), Pierre Magistretti (Brain Mind
Institute, EPFL, KAUST, Lausanne, Switzerland) and Marcus Raichle
(Washington University School of Medicine, St Louis, USA). The
prize will be awarded on July 5th, 2016 at the 10th
FENS (Federation of European Neurosciences Societies) Forum of
Neurosciences in Copenhagen by an international jury led by Nikos
Logothetis (Max Planck Institute for Biological Cybernetics,
Tübingen, Germany).
Contribution of the three laureates to The understanding of
Neuroenergetics
Our brain only represents 2% of our weight, yet it alone consumes 20% of
the oxygen and 25% of the glucose in our body. Initially, the scientific
community were of the opinion that this energy allocation was devoted to
functional activities of our brain (reading, thinking, making a
movement, etc.). However, in 1988, Marcus Raichle published data in Science
showing that these functions involved only 5% of the total energy in our
brain, the remaining 95% being for the basal functions: ensuring the
electrical and synaptic activity of the neurons. This discovery would
have been impossible without his major contribution to the development
of positron emission tomography (PET) and functional nuclear magnetic
resonance imagery (MRI). In 1988, in Nature, he published the
first integrated strategy for producing and interpreting images of the
brain in activity. These techniques were also vital to the work of
David Attwell. Using functional MRI together with electrophysiology,
Attwell showed that the grey matter containing the neuronal cellular
bodies consumes more energy than the white matter (Journal of
Cerebral Flow and Metabolism, 2001). Myelinisation reduces the
energy cost of reestablishing membrane potential after an electrical
signal is propagated. Thus, 100 billion neurons in our grey matter
require a phenomenal amount of energy to stimulate the 50 trillion
connections that they form. These functions are controlled by a tight
relation between the neurons and the glial cells, as shown by David
Attwell. The work of Pierre Magistretti has also revealed the importance
of neuron/astrocyte energy coupling for the functioning of the
stimulatory neuronal pathways (PNAS, 1994), including those that
secrete glutamate. These neuronal pathways are the most energy
demanding. Once it is liberated in the synapse, the glutamate is
captured by the astrocytes to produce lactate. This energy substrate is
then transmitted to the neurons, which convert it very rapidly into
energy (Journal of Neuroscience, 2011). This energy coupling is
vital for major cerebral functions like learning or memory (Cell,
2011), and is also able temporarily to compensate the lack of glucose
occurring, for example, after a stroke (Stroke, 2012). Strokes
are characterised by an interruption to part of the cerebral
circulation, triggering the death of the first neurons located in the
nonirrigated area within only a few minutes. This sensitivity is due to
a combination of their high consumption of energy and their inability to
store energy. David Attwell and his team have further shown that the
neuronal cells are supplied more from blood capillaries than from
arteries and arterioles. They have shown that the pericytes, which wrap
around the cerebral blood capillaries, are able to control the blood
pressure, and hence to regulate the blood flow in the brain (Nature,
2006). In the event of a stroke, these cells die quickly, permanently
affecting the cerebral blood circulation and eventually preventing the
complete recovery of the patient (Nature, 2014). Thus, the
research work carried out by the three laureates of the 27th Neuronal
Plasticity prize of the Fondation IPSEN has enabled new paradigms to be
established in neurosciences, which have both advanced our knowledge on
the functioning of the brain and opened up new perspectives in
biomedical research.

About the Fondation IPSEN
Established in 1983 under the aegis of the Fondation de France, the
ambition of the Fondation IPSEN is to initiate a reflection about the
major scientific issues of the forthcoming years. The long-standing
mission of the Fondation IPSEN is to contribute to the development and
dissemination of scientific knowledge by fostering interaction between
scientists and clinicians. It has developed an important international
network of scientific experts who meet regularly at meetings known as Colloques
Médecine et Recherche, dedicated to three main topics:
neurosciences, endocrinology and cancer science. Moreover the Fondation
IPSEN has started several series of meetings in partnership with the
Salk Institute for Biological Studies, the Karolinska Institute as well
as with the science journals Cell and Science. The
Fondation IPSEN produced several hundred publications and more than 250
scientists have been awarded prizes and grants.
