In vitro neonatal biomimetic (nMIMIC) model and methods of using same

Abstract:

In vitro biomimetic models of the neonatal immune system are provided along with methods of using the models in pre-clinical assessment of infant immune cell-mediated and humoral responses to immunogenic stimulation, such as vaccination. The models include one comprising cord blood-derived T follicular helper cells and B cells, and one comprising cord blood-derived dendritic cells and CD4+ T cells. The models can be used, for example, to assess candidate vaccines via analysis of cellular responses to antigen and vaccine exposure.
