NeuroProof presents Parkinson’s prevention assay
NeuroProof presents its novel Parkinson’s prevention assay at the 25th Annual Conference of the German Society for Cytometry, October 7-9th, 2015. The work will be presented by Prof. em. Dieter G. Weiss, one of the co-founders of NeuroProof.
Here, we present the use of human iPSC-derived dopaminergic neurons as a functional phenotypic in vitro model system for screening novel Parkinson's relevant compounds. This functional assay adds to the NeuroProof strategy to screen compounds aiming to treat early patho-physiologies.
NeuroProof at the ISSCR 2015 in Stockholm, June 24-27th 2015
NeuroProof presents its iPSC-based Parkinson’s disease assay with a poster, poster board number W-1318, on Wednesday 24th of June from 18:30-20:30. The poster will be presented by Benjamin Bader who was responsible for development of this assay (download poster).
The aim of this development was to use human iPSC-derived neuronal networks containing dopaminergic neurons growing on micro-electrode arrays (MEAs) for the functional validation of phenotypic in vitro screening Parkinson's (PD) relevant compounds.
With this assay NeuroProof paves the way to screen compounds to treat early patho-physiologies of this disease. It is possible to monitor a compounds effect to prevent or rescue Parkinson’s like functional disturbances.
NeuroProof and Mead Johnson present novel in vitro assay for testing natural products
ESPGHAN meeting in Amsterdam, May 6-9th 2015
NeuroProof collaborates with Mead Johnson Nutrition to study the effects of natural products such as omega-3 fatty acid DHA on brain function and excitation. We present a novel assay using MEAs to identify compound combinations which are beneficial for functional neuronal development.
At our poster titled "Combination of DHA with bioctive whey protein, natural bovine complex lipids accelerates functional maturation of neuronal networks in vitro" (PO-N-0365, Abstract online in Abstract book) we present the results of functional phenotypic in vitro testing of natural products such as omega-3 fatty acid DHA and combination using the MEA technology and multi-parametric data analysis. At the 48th Annual meeting of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition we show for the first time that natural products significantly accelerate early neuronal maturation in vitro. Our current research explores whether these findings translate into functional benefits in vivo.
NeuroProof at the Axiogenesis User Group Meeting in Cologne, April 15-17th 2015
NeuroProof presented the latest results on the functional evaluation of human iPSC-derived dopaminergic neurons (Dopa.4U, Axiogenesis) growing on micro-electrode arrays (see stem cell characterization info sheet).
"Using Dopa.4U neurons, we have added another assay to our Parkinson screening service. We now have shown the similarities and differences between mouse primary neurons and human iPSC-derived neurons." Dr. Bader said after the presentation. Thus, NeuroProof's aim to transfer the primary mouse in vitro MPP+ model to human iPSC-derived neurons was successful. Our customers can now compare compound efficacies on human and mouse cultures to observe species-dependent specificities for the screening of Parkinson's drugs.

Facing seizurogenic effects in drug discovery leads to significant attrition rates which partly is due to the lack of suitable in vitro test systems. Further, presently used brain slice or behavior assays for predicting seizure risk are accompanied by low throughput and high demand for animal tests and the fact that results from rodent tests not always translate into the human situation. Microelectrode arrays (MEAs) with dissociated neurons are currently under investigation using both mouse and human induced pluripotent stem cells (hiPSC) to serve as an alternative to current state-of-art. Contrasting mouse and human neuronal in vitro MEA systems therefore is needed to improve clinical translation.
We cultured primary mouse cortex and hiPSC neurons on multiwell microelectrode arrays. After 3-4 weeks in vitro, we tested known seizurogenic compounds and analyzed the recorded spike trains by computing more than 200 parameters to describe the compound’s functional phenotype. The established fingerprints reveal a common seizure-specific phenotype identified by AI-based classification analysis. Using this classifier, we compare the predicted seizure risk for several clinical compounds in a concentration-dependent manner between human iPSC-derived neuronal networks and those from functionally mature primary mouse cortical networks.
In summary, our data underlines the common understanding that the MEA technology allows dissecting the functional differences between hiPSC- and mouse neuronal culture models. Here, we present a tool for investigating and comparing the safety margin of novel drug candidates in rodent and human cells and thereby complement the toolbox for prediction of functional seizurogenic risk assessment.
Meet NeuroProof at the ECNP 6-9.10.2018 in Barcelona
The potentials and limitations of personalized induced pluripotent stem cell (iPSC) models in neuropsychiatry
Meet NeuroProof at a Brainstorm Meeting at the international conference ECNP 6-9.10.2018 in Barcelona
The Brainstorm Meeting will be held on Sunday 7th of October 2018
This brainstorm meeting will be organized by Prof. Edna Grünblatt from University Hospital of Psychiatry Zurich and Dr. Olaf Schröder from NeuroProof GmbH, Germany.
Within this meeting, the enormous progress in establishing disease models for psychiatric disorders with iPSC based technologies and functional phenotypic screening will be addressed.
Practical experiences with such models will be presented.
We will be happy to meet you at the ECNP and to discuss with you this fascinating topic.
Neuropsychiatry disorders such as autism, schizophrenia, bipolar and attention-deficit hyperactivity disorder (ADHD) have polygenetic, neuro-immunological, environmental and developmental causes, with complex etiology to be yet revealed. Recent advancement in research (that includes patient-specific disease modelling, new methods of treatment monitoring, personalized medicine, and new differential diagnostic markers) opened new opportunities to study such disorders and differentially diagnose and predict treatment response: in this brainstorming session, the speakers will discuss the potentials and limitations of induced pluripotent stem cells (iPSC) in neuropsychiatry. Since Yamanaka and colleagues generated the first iPSC, many attempts to generate these cells also from patients with psychiatric diseases were made. The generation of patient- and disease-specific iPSC cultures, following standardized and reproducible protocols, and the use of these cultures in drug discovery still require rigorous validation of the methods and continuous improvement of protocols and read outs. iPSC models allow imaging, molecular, cellular, biochemical and functional read outs to investigate neurodevelopmental trajectories and to model the course of the disease development while monitoring treatment success. One of such methods is the functional label-free read outs using microelectrode arrays (electrophysiology), to correlate patient diagnostic outcomes with outcomes generated from iPSC models. The discussion will focus on different topics concerning the use of iPSC in neuropsychiatry, such as brain region-specific models, co-culturing with glial cells, organoids, quality markers, the influence of epigenetic disturbances and the use of genetic modifications.
