Increased understanding of the complex tumor microenvironment and its interactors has boosted therapeutic interest and highlighted the importance of the development of innovative in vitro bioassays to address all the players of the cancer immune response and thereby potentially provide pivotal information on the functional dynamics of candidate therapeutics. Regulatory T cells play an important role by downregulating the anti-tumor response. Their regulation mechanisms constitute an important target for new therapeutics. To study these mechanisms in a human model, suppressive Treg bioassays, mimicking the suppressive action of these cells, were developed and optimized.
