European project IMLINFO: New article published in Cancers
We are thrilled to see our work in the European project IMLINFO finally published in the journal Cancers. IMLINFO’s goal is to determine the efficacy of new immunotherapy treatments against non-Hodgkin’s lymphoma tumours associated with a 3D culture platform. It involves 8 organizations located in Spain and France.
Our research for this project focused on the follicular lymphoma, which accounts for 20-30 percent of all non-Hodgkin lymphoma cases and is still considered as incurable. We conceived a realistic 3D model of t(14;18)-positive B-NHL cell culture, that allows a more robust drug testing by 2D and 3D imaging monitoring techniques.
Imactiv-3D was involved in the 3D characterization of these models using light sheet fluorescence microscopy. This technology has been chosen for its numerous advantages:
It allows to penetrate a 3D sample in depth, quickly and in full,
It exposes a sample to up to 5000 times less energy than confocal fluorescence microscopy, minimizing photo-bleaching and photo-induced cell damage,
It results in high resolution and multichannel fluorescence images.
Imactiv-3D also specifically developed and implemented an image processing pipeline to automatically segment the samples in 3D from light sheet microscopy acquisitions. The algorithm’s output allowed to estimate various 3D morphological parameters as volume, eccentricity, sphericity, and roundness.
The article entitled “3D model characterization by 2D and 3D imaging in t(14;18)-Positive B-NHL: Perspectives for in vitro drug screens in follicular lymphoma” is available here.
Conference paper with IPSEN for Toxins 2021
As part of our collaboration, IPSEN Innovation and Imactiv-3D published a conference paper "3D reconstruction and analysis of neuromuscular junction (NMJ) distribution in whole skeletal muscles in the rat using light-sheet microscopy" in Toxicon for the Toxins virtual conferences 2021.
The goal of this work was to get qualitative and quantitative data on the NMJ phenotype to study the Botulinum neurotoxins diffusion after intramuscular administration. An automated image processing methodology, including 3D image denoising and segmentation, was developed to count NMJ.
We used light sheet microscopy to image 5 types of rat muscles and investigate the distribution of NMJ.

CROI 2021: Joint work with the Pasteur Institute on HIV-1
We are proud to see our joint work on HIV-1 with Pasteur Institute being presented by the
talented Dr Francesca Di Nunzio during the CROI (Conference on Retroviruses and Opportunistic
Infections) happening in March 6-10 2021.
To uncover the HIV-1 DNA fate in the nuclear landscape, they directly tracked the viral DNA and viral RNA by coupling
NeoVirTech's HIV-1 ANCHORTM technology with RNA FISH or MCP-MS2 RNA-tagging bacterial system.
The computational imaging analysis developed by Imactiv-3D revealed that proviral forms are early located in proximity of the nuclear
periphery of mitotic and non-mitotic cells.
This challenging analysis includes localization of viral DNA, viral RNA and various nuclear bodies together with 3D distance estimation on a submicron
scale inside nuclei.
Our image processing expert, Renaud Morin, developed a multichannel segmentation algorithm that enables the automatic, precise and robust
identification of all these components in 3D.
Based on state-of-the-art image processing methods, this quantification tool paves the way towards refined colocalization study and thus better
understanding of HIV mechanisms.
The Pasteur Institute team was able to show that HIV-1 infection restructures nuclear membrane-less organelles (HIV-1 MLOs), enriched in both viral proteins and speckle factors. Integrase proteins
are retained in HIV-1 MLOs, while the late retrotranscribed DNA was excluded from them, indicating that those structures are not proviral sites,
but orchestrate viral events prior to the integration step. In fact, they show that HIV-1 MLOs are sites of nuclear RT.

Partnership with ThermoFisher scientific
Alzheimer's is the most common cause of dementia, a general term for memory loss and other cognitive disabilities serious enough to interfere with daily life. Alzheimer's has no current cure, but treatments for symptoms are available and research continues to find better ways to treat the disease, delay its onset, and prevent it from developing.
We worked closely with Amylgen, a French Preclinical CRO, to better understand Alzheimer’s and its impact on the brain micro-vascular network.
Imactiv-3D created a movie with Amira Software (from Thermo Fisher Scientific) from light sheet microscopy acquisitions and was able to visualize the whole vascular network of a mouse brain in 3D, allowing to study its anatomy in space. The animation scenario could then be applied identically on different conditions in order to make a first reliable visual comparison of global vascular architecture.
In addition to this advanced visual analysis, Imactiv-3D is able to perform 3D quantification studies, confirming the decrease in vascular network density, and modified distribution of vessels size in diseased brains’ cortex.

Partnership with Carl Zeiss SAS to offer innovative integrative solution
Imactiv-3D, the innovative CRO that helps preclinical studies get more predictive thanks to its expertise in biology, 3D imaging and image processing, announced that it has entered into a strategic partnership with the 3D imaging and microscopy leader Zeiss. This partnership has been signed simultaneously with the acquisition and installation of a state-of-the-art light sheet microscope in Imactiv-3D’s laboratories. As the 3D microscopy tends to become a technique that is more and more democratized and accessible, it remains complex and produces a large volume of data, often difficult to process for the users. That is why the alliance between the leader in microscopy and experienced users and image processing engineers is particularly interesting. It allows this technology to be used to its fullest potential and to improve the robustness of the results obtained. The purpose of this partnership is to provide an integrative and innovative solution to clients needing optimum image acquisition and processing in 3D.
While Zeiss brings its excellence in 3D microscopy and imaging techniques, Imactiv-3D will use its expertise in sample processing for imaging (labelling, optical clearing, conditioning), in 3D imaging (mainly light sheet) and 3D image processing. That alliance thus enables the full potential of the state-of-the-art imaging technology to be exploited and put to best use in preclinical research. “This partnership is an opportunity for us to be able to offer a complete solution and expertise on the light sheet to our future users, from sample preparation, to 3D analysis, including clearing methods, acquisition and 3D visualization,” said Fabrice Schmitt, Head of Sales for Carl Zeiss SAS.
Jean-Michel Lagarde, founder and CEO of Imactiv-3D, is excited about this unique partnership: “This partnership between the company Carl Zeiss SAS and Imactiv-3D is a great opportunity for the development of our company. It is a recognition of the work accomplished by the team to become experts in light sheet microscopy, in sample preparation and image processing specific to this imaging modality.” Contact information:

Ph.D. Defense of Aurélie Gomes
On Tuesday, december 17, 2019, Aurélie Gomes successfully defended her thesis entitled "Evaluation of proliferation in tumor spheroids".
Her work, under a CIFRE agreement, is the result of 3 years of intense collaboration between the "Innovation for the study of 3D proliferation - IP3D" team at ITAV - Institut des Technologies Avancées en sciences du Vivant and IMACTIV-3D.
She was particularly interested in the evaluation of the proliferation in the 3D model of tumor spheroids and its regulation, in particular by oxygen. She has implemented experimental approaches to in toto antibody labelling, light sheet imaging and image analysis.
Her work has led to the development of methods and tools of interest in the study of cancer biology and response in anti-tumor pharmacology. Their application shows the importance of physioxia for the study of proliferation and the evaluation of drug response.
We are very happy that Aurélie Gomes continues the adventure with us. She will join IMACTIV-3D as a young doctor in January 2020 to share her expertise with our customers as R&D project manager in biology and imaging.

IMALC Project Results
The IMALC project comes to an end! This research project was aiming to treat follicular lymphomas with anti-CD20 antibodies, and to develop quantitative imaging tools to evaluate their efficacy by light sheet microscopy.
To conclude, this transversal and interdisciplinary research project made it possible to:
- Characterize biologically relevant study models
- Model lightsheet imaging clinical observations, and maybe in the longer run, to explain why monoclonal antibodies treatments are less effective in patients with high-tumor burden follicular lymphomas or with an increased immune checkpoint expression.
This project is therefore part of a global research effort to better understand lymphomatous pathology and the mechanisms involved in therapeutic treatments in order to identify targets and anticipate resistance mechanisms. This represents a major challenge for a pathology that is currently considered incurable.
Imactiv-3D team has developed a quantitative analysis of the distribution and diffusion of MAb (Monoclonal antibody) on these 3D models of follicular lymphomas (MALC) based on 1) light sheet microscopy imaging of MALC after treatment with therapeutic ACMs and 2) the development of a custom methodology for efficient and automated image processing and analysis to quantitatively characterize the spatiotemporal biodistribution of MAbs within MALC. This project was based on the skills and expertise found in team N°9 of the CRCT (Toulouse Cancer Research Centre), on the imaging platform of the ITAV (Institut des Technologies Avancées du Vivant) and in the company IMACTIV3D.
Joint publication with INSERM in OncoImmunology
Imactiv-3D is very pleased to announce the publication of a new scientific article in the OncoImmunology Journal on follicular lymphoma, resulting from a collaboration with the Unit UMR1037 of the INSERM in Toulouse (France).
The article, entitled “Boosting γδ T cell-mediated antibody-dependent cellular cytotoxicity by PD-1 blockade in follicular lymphoma” is already available (DOI: 10.1080/2162402X.2018.1554175). This article presents data providing a rational treatment for follicular lymphoma by PD-1 blockade aimed at boosting γδ T cell anti-tumor functions in this pathology.
Imactiv-3D took charge of the image processing of 3D co-cultured MALC for characterization and quantification of the penetration of γδ T cells and monoclonal antibody (GA101).
Scientific publication in virology
Imactiv-3D is pleased to announce the publication of a new scientific article entitled “In vivo labelling of adenovirus DNA identifies chromatin anchoring and biphasic genome replication” in the Journal of Virology (DOI: 10.1128/JVI.00795-18) available here.
This study has been conducted in collaboration with the CNRS UMR5234 lab in Bordeaux (France) and with NeoVirTech. It shows that the real-time genome imaging system developed revealed hitherto uncharacterized features of adenoviral genomes in vivo. This system is capable of identifying new spatiotemporal aspects of the adenovirus life cycle and is potentially transferable to other viral systems with a double-stranded DNA phase.
Imactiv-3D team was involved in the characterization of viral replication centers in human cells and the image processing (denoising and deconvolution).

Our team developed a new procedure to visualize, analyze and quantify the pharmacological activity of drugs on 3D multicellular spheres grown in a physiological matrix.
The aim of this study was to propose a robust and efficient imaging and analysis pipeline to assess with quantitative parameters the efficacy of a particular cytotoxic drug. HCT116 colorectal adenocarcinoma tumor cell multispheres were observed with structured illumination 3D microscopy and the images obtained were processed with custom analysis tools.
We were thus capable of automatically detecting spheres in a large volume of matrix in 96-well plates. This procedure was used to evaluate drug efficacy in HCT116 spheroids treated with different concentrations of topotecan, a DNA topoisomerase inhibitor. This work demonstrates that quantitative image analysis is an effective mean to evaluate and quantify the cytostatic and cytotoxic activities of anticancer drugs on 3D multicellular models grown in a physiological matrix.
