 State-of-art innovations in human in vitro 3D mucosa models and assays

Inno4Vac icon transparent_edited_edited.

In a nutshell

Subtopic 3 sets out to develop cell-based human in vitro 3D models that simulate an infection at the mucosa and more reliably predict immune protection. These models will be combined with the development of related functional immune assays for clinically relevant (surrogate) endpoints.

The scientific and technical objectives of this subtopic are:

  • Develop next-generation human in vitro 3D models for gastro-intestinal, respiratory and urovaginal mucosae that include relevant immune-system components

  • Test & validate the in vitro 3D models using selected Pathogens

  • Develop interventions and integrated functional immune assays addressing endpoints likely to be associated with protection and convalescence and evaluating novel immune surrogates of protection using existing samples and reagents and those from convalescent patients and other control subjects, human challenge models and vaccination studies

  • Use of pathogen strains representative of the expected heterogeneity encountered in patients

Prof. Dr. Cécile van Els is Senior immunologist at RIVM and Professor of Vaccinology at the University of Utrecht, the Netherlands.  She is an expert in the field of correlates of protection to human (respiratory) pathogens. Her current activities include identifying protective immune mechanisms and antigens in natural infection studies. Cécile has >100 publications.

Martine Chabaud-Riou is a senior immunologist at Sanofi Pasteur, Marcy-l'Etoile, France. She has more than fifteen years of experience in managing the scientific and technical aspects of the development of new vaccines in the context of preclinical and immunological research. As a scientific researcher, she has several publications in immunology and vaccines.

Main WP objective

WP12

3D in vitro Models and assays: Roadmap, standardisation and guidelines

To accompany and underpin the scientific-technical development of the in vitro 3D mucosa models and assays by developing a strategy and roadmap for the ultimate integration of the models and assays into pharmaceutical vaccine development and to sustain project outputs long term.

Led by Katie Huber, Paul-Ehrlich-In­sti­tut (PEI) - the Federal Institute for Vaccines and Biomedicines

WP13

Development of model and assay prototypes - Gastro-intestinal

Development of next generation in vitro 3D models of the gastrointestinal (GI) mucosa, based on human induced pluripotent stem cells (hiPSC) emulating essential organotypic microphysiological conditions created by precisely regulated biochemical and biophysical cues.

Led by Alexander Mosig, Jena University Hospital; Stephane Temmerman, GSK and Apurva Kulkarni, Takeda

WP14

Development of model and assay prototypes - Respiratory

Implement advanced next-generation respiratory mucosal models to evaluate vaccine-induced protective and detrimental immune responses in the context of infections with influenza and respiratory syncytial virus (RSV).

Led by Puck van Kasteren, Rijksinstituut voor Volksgezondheid en Milieu (RIVM); Nathalie Mantel, Sanofi and Kevin Buno, GSK

WP15

Development of model and assay prototypes - Urovaginal

Development of complex in vitro 3D infection models of the urovaginal (UV) mucosa with features resembling human tissue architecture and physiology and to explore the feasibility of including immune cells of innate and adaptive immune compartments to investigate protective effector immune mechanisms. We will focus on Neisseria gonorrhoeae (Ngo) and Herpes Simplex Virus-2 (HSV-2) to establish infection models.

Led by Thomas Rudel, Julius-Maximilians-Universität Würzburg (JMU) and Isabel Delany, GSK
