For research purposes, the<unk>  cell-based assay continues to provide an in vitro correlate of T cell function. Further characterization of the<unk> s, accessory cells (dendritic cells, macrophage) and cytokines that participate in the<unk>  have been done as this assay continues to be used to define mechanisms for understanding cellular immune function in vitro.
