The identification of T-cell subsets and assessing their ex vivo activation is a key step in the adoptive cell therapy process. To facilitate this workflow, we developed a high throughput flow cytometry-based, multiplexed assay to measure T cell activation in different T-cell subsets. PBMCs from multiple donors were profiled prior to and after T cell enrichment with CD3/CD28 magnetic beads. Purified T cells were cultured in the presence of the beads and media containing IL-2 for 3 days and cell phenotypes and secreted cytokines were analyzed. For each sample well, 11 cytokines and 13 cellular endpoints were measured each day over the course of a three-day activation protocol including quantifying cells expressing the activation markers CD69, CD25 and HLA-DR. A 96-well sample plate contained T cells from 12 different donors, with each sample analyzed in quadruplicate using two different sample dilutions. The plates were read on the iQue Screener Plus and the high-content data was analyzed using the integrated ForeCyt software. The results indicate a time course dependent, donor to donor variation in T-cell activation. These high throughput, large-scale flow cytometry studies provide extensive T cell activation and subset profiles from multiple donors with assay times of ~15 minutes. The adoption of these assays can provide actionable data to optimize adoptive cell therapy culture conditions and improve manufacturing protocols.
