  • Patent number: 11834647
    Abstract: The present invention relates to an in vitro immune synapse system and a method of in vitro evaluating immune response using the same. The in vitro immune synapse system includes antigen-presenting cells (APCs) and at least one cell type of several specific T cell subtypes isolated from peripheral blood mononuclear cells (PBMCs), all of which is from a same individual of pigs. When a test sample is co-cultured in the in vitro immune synapse system for a given period, it can be determined that the test sample is immunogenic, immunostimulatory or not according to the immunization-related changes of these cells, thereby potentially replacing some kinds of animal experimentation.
