The recognition of peptide-MHC (pMHC) complexes by T cells is the cornerstone of cellular immunity, enabling the elimination of infected or tumoral cells. pMHC can thus be leveraged as a detection tool for T cells.
Stanford researchers in the Mark Davis Lab have developed a human cell culture system to grow 3D immune organoids within hydrogel structures using limited cellular input that can be adapted to large screening assays for flexible downstream immunological readouts.
