Title: Immune Cell function and Effect of Immune Checkpoint Inhibitor in Freshly Dispersed Human Tumors

Poster number: P-3156

Presenter: Satoko Unno, Pharmacology Business Unit

Presentation Summary
Human cancer tissues contain not only tumor cells but also a variety of immune cells, and their interactions shape the complex tumor microenvironment (TME). A deeper understanding of immune responses within the TME is essential for the development of novel immunotherapies.
In this study, fresh human cancer tissues were enzymatically dissociated into single-cell suspensions, and the composition and function of tumor-infiltrating immune cells (TILs) were analyzed by flow cytometry. We observed infiltration of heterogeneous immune cell populations, including PD-1–high CD8⁺ and CD4⁺ T cells as well as tumor-associated macrophages (TAMs).
Upon anti-CD3 antibody stimulation, TILs produced IFNγ, which served as a functional readout of T cell responsiveness and reflected the immune status of the TME. This functional assay may therefore be valuable in evaluating immunological competence within tumors.
In addition, we also present data on the effects of immune checkpoint inhibitors, which provide further insights into the development of future immunotherapies.

Axcelead DDP’s Soulution
At Axcelead DDP, we have established a unique system for obtaining fresh human cancer tissues, which serve as an extremely valuable tool in drug discovery research. Using these fresh cancer tissues, our in vitro evaluation system for evaluating immune responses tumor tissues is highly useful for the discovery and development of novel cancer immunotherapies.
Axcelead DDP has access to a wide range of human tissues and cell types beyond cancer. Utilizing comprehensive omics analyses, we support research into disease mechanisms and biomarker discovery.
If you are interested in any particular tissues or evaluation systems, please feel free to contact us.
