Development of a Lymphoid Organ-Chip to Evaluate mRNA Vaccine-Boosting Strategies

In this webinar, Lisa Chakrabarti, PhD, from Institut Pasteur described how her team developed a lymphoid Organ-Chip (LO Chip) using the Emulate Chip-S1® Stretchable Chip to address the challenge of predicting vaccine immunogenicity in humans. Dr. Chakrabarti went into detail about how the LO chip recreated key lymphoid tissue features, including T cell/B cell interactions and emigration of matured plasmablasts, and demonstrated the capability to assess responses to mRNA vaccines. 

Key highlights from this webinar include how: 

  • The model recreates lymphoid tissue features, including CD4+ T cell/B cell cluster formation and emigration of matured plasmablasts. 
  • The LO Chip effectively mimics vaccine boosts, amplifying SARS-CoV-2 Spike protein-specific B cells and antibody production.
  • The dynamically perfused culture system outperforms traditional 2D and 3D static cultures in immune response simulation. 
  • The LO Chip is responsive to both protein and mRNA-encoded antigens, highlighting its potential for preclinical evaluation of vaccine boosting strategies.
