The Institute of NeuroPhysiopathology (INP) is a training and research centre of excellence that combines basic and translational research to study neural cell organisation, function and interaction, the molecular and cellular bases of major brain diseases, and to develop innovative cellular and molecular therapeutic strategies.
The PFNT Facility is a coherent set of exploration tools in neurobiology allowing research at the molecular, cellular and integrated levels.
During the 14th EANO annual meeting 3 members of INP team #8 presented their work on Glioma in a plenary conference «CDKN2A homozygous deletion is a strong adverse prognosis factor in diffuse malignant IDHmutant gliomas» Dominique Figarella Branger, a short talk «Plasmatic differential scanning fluorimetry profiles discriminate glioma patients from healthy controls» Emeline Tabouret and two posters «P11.06: Non epigenetic effect of vorinostat in glioblastoma cells» and «EB1-dependant long survival of glioblastoma cancer stem-like cells tumor
Nadia Merad Coliac, plastic designer, joined the NOSE (Nasal Olfactory Stemness and Epigenesis) team, as an Associate researcher. At the crossroads of several disciplines, she develops an experimental work of art and science, in the field of bioluminescence. She is considering a therapeutic application in patients with autism spectrum disorders (ASD). Recently, Nadia published Lumière vivante - Théorie et pratique de la bioluminescence (Living light - theory and use of bioluminescence) - L’Harmattan eds.
Many members of the INP attended the annual Canceropole PACA meeting in the Palais des Congrès of St Raphaël on the 4th and 5th of july. In the frame of the translational research call, F. Devred (INP team 9) & E. Tabouret (INP team 8) presented the results and perspective of their project "Next generation plasma profiling of gliomas using nanoDSF: toward a new prognostic and monitoring tool"
INP team 8 and 9 and PINT members being part of the French Microtubule Network, several members presented their work at the 4th French Microtubule Network gathering in Rennes on the 1srt and 2nd july 2019, in the "Microtubules and their regulators : new therapeutic targets" session and the "Microtubules, assembly and regulation" session. Pascale Barbier presented her work "", Raphael Berges his work "Proscillaridin A exerts anti-tumor effects through"GSK3 activation and alteration of microtubule dynamics in glioblastoma" and François Devred a new method of "Functional screening of therapeutic agents and targets using nanoDSF "
An article entitled "Le CNRS et Aix-Marseille Université signent un accord avec la PME Vect-Horus sur la propriété intellectuelle", published in the CNRS Innovation Letter of 20 June 2019 and relayed by the INSB site, features the agreement signed by CNRS, AMU and Vect-Horus establishing the intellectual property rights regime and the exploitation of patents.
Our last work on IAPs : "Inhibitor of Apoptosis Proteins (IAPs) Determines Glioblastoma Stem‐Like Cell Fate in an Oxygen‐Dependent Manner" is now published in Stem Cells. We highlighted that pharmacological inhibition of IAPs by Smac mimetic GDC-0152 was able to decrease glioblastoma stem-like cells viability in hypoxia by decreasing cell proliferation and increasing apoptosis through ATR and TNFα pathways
During the last NeuroFrance congress held from May 22 to 24, 2019 at the Palais des Congrès in Marseille, the INP distinguished itself through 20 posters, 4 oral communications, and 1 symposium moderation, not to mention the organization of the "Art in Mind" exhibition, showing not only the richness and quality of his research but also his open-mindedness.
Les travaux récents de l'équipe NeuroCyto pour dévoiler l'architecture des des axones font l'objet d'un article dans l'édition du vendredi 17 Janvier de La Provence.

L'équipe 8 (GlioME) a le plaisir d'accueillir deux étudiants en Master 2, Anaïs Arathni étudiante en Master Biologie Santé et Emmanuel Snacel-Fazy étudiant en Master Neurosciences. Anaïs travaillera avec Aurélie Tchoghandjian sur la caractérisation des cellules immunitaires recrutées sur le site tumoral suite au traitement par mimétiques de Smac. Emmanuel travaillera avec Chiara Bastiancich sur le microenvironnement de la résection tumorale du glioblastome.
Christophe Leterrier, leader of the NeuroCyto ATIP team, wrote a Spotlight in the Journal of Cell Biology highlighting a nice recent paper from the group of Pei-Lin Cheng in Taiwan. In this article, Lee et al. showed how degradation of the chloride transporter NKCC1 by proteasomes anchored at the AIS have a key role in lowering the intracellular chloride concentration, leading to the perinatal reversal of GABA effect from excitatory to inhibitory.
Thanks to her expertise in the diagnosis of central nervous system tumours arising in children and young adults, Dominique Figarella-Branger from the GlioME team (Team 8) was involved last year in 5 articles published in high-impact factor journals (>18). These articles are becoming references in this field:
- The molecular landscape of ETMR at diagnosis and relapse. Nature. 2019 Dec;576(7786):274-280. PMID: 31802000
Maladie d'Alzheimer : une nouvelle année pleine d'espoir.
In its week-end edition (january the 4th & 5th 2020), the daily newspaper La Marseillaise devoted its "Provence Terre de Science" page to Alzheimer's disease reserach.
On this occasion François Devred (INP team 9 / PINT platform) answered a few questions on the molecular characterization of this complex protein (to be downloaded by clicking here )
First work of 2020 work is out for the NeuroCyto team! A collaboration with Matt Rasband’s lab in Nature Communications. This is a significant paper for the axon initial segment field: Matt’s lab used BioID of key AIS proteins for mapping AIS components. Dozens of new candidates for future studies! We performed super-resolution microscopy of several of the newly identified AIS components. IN particular, we showed that Mical3, a protein linking microtubules and actin, forms clusters along the AIS that are not periodically organized along the actin/spectrin scaffold.
If you speak French, you can listen to “La Méthode Scientifique”, a program on the France Culture radio which highlighted the recent Nature Communications article from the NeuroCyto team.

Our work on the ultrastructure of the periodic actin/spectrin scaffold along axons is out in Nature Communications.
In a large cohort of 911 high-grade IDH-mutant gliomas from the French national POLA network, we investigated the prognostic value of the CDKN2A gene homozygous deletion as well as WHO grading criteria (mitoses, microvascular proliferation, and necrosis).
We showed that:
- CDKN2A homozygous deletion characterizes diffuse malignant IDH-mutant gliomas with worst outcome.
- Microvascular proliferation stratifies IDH-mutant gliomas lacking CDKN2A homozygous deletion.
On thursday december the 12th, most of INP and Vect-Horus members got together and spent a day in the Black Stone pub, Marseille, to celebrate the fact that nearly two years after its creation, the Institute of NeuroPhysiopathology is finally located on Tmone Campus.
