A novel dendritic cell-based direct ex vivo assay for detection and enumeration of circulating antigen-specific human T cells.
Cytotechnology 2018 May 8
Although a variety of assays have been used to examine T cell responses in vitro, standardized ex vivo detection of antigen-specific CD4+ T cells from human circulatory PBMCs remains constrained by low-dimensional characterization outputs and the need for polyclonal, mitogen-induced expansion methods to generate detectable response signals. To overcome these limitations, we developed a novel methodology utilizing antigen-pulsed autologous human dendritic target cells in a rapid and sensitive assay to accurately enumerate antigen-specific CD4+ T cell precursor frequency by multiparametric flow cytometry. With this approach, we demonstrate the ability to reproducibly quantitate poly-functional T cell responses following both primary and recall antigenic stimulation. Furthermore, this approach enables more comprehensive phenotypic profiling of circulating antigen-specific CD4+ T cells, providing valuable insights into the pre-existing polarization of antigen-specific T cells in humans. Combined, this approach permits sensitive and detailed ex vivo detection of antigen-specific CD4+ T cells delivering an important tool for advancing vaccine, immune-oncology and other therapeutic studies.
