The PFNT Facility is a coherent set of exploration tools in neurobiology allowing research at the molecular, cellular and integrated levels.
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.
In the CNRS Innovation Letter of April, there is an article entitled "Des molécules vectorisées pour cibler les maladies neurodégénératives" featuring the research collaboration agreement signed by Vect-Horus and Johnson & Johnson subsidiary Janssen Pharmaceuticals for treating neurodegenerative diseases.
On the 26-31st March, the 14th International Conference on Alzheimer's and Parkinson's Diseases (ADPD) and related neurological disorders was held in Lisbon, Portugal. This year, almost the entire team 1 and team 6 went to this major event and our students: Laurie Arnaud, Laura García González and Dominika Pilat took the opportunity to present their work on a poster.
The LEGO Pumpy (or more officially NanoJ-Fluidics) paper is out in Nature Communications! A joint venture between the INP NeuroCyto team and the Henriques lab, this article (previously available as a preprint on bioRxiv) details how to build a fully open-source multi-channel syringe pumps with LEGO and Arduino.
As part of her PhD, Sylvie Carmona investigated the beneficial effects of NV669, an aminosterol derived from squalamine on human pancreatic and hepatic cancer models. In vitro results exposed in this paper showed that NV669 inhibited the proliferation of cancer cells, induced cell cycle arrest and subsequent apoptosis. Moreover, NV669 inhibited PTP1B activity and impacted adhesion molecules expression. This suggests that NV669 by inhibiting PTP1B would affect cell contacts and would induce apoptosis.

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:
