Importance of tumor microenvironment for immune response against cancer shown in patients tissues

The growth and spread of colorectal cancer (CRC) can be prevented partially by T cells but tumor microenvironment may pose difficulties. In this study, the researchers aimed at determining if T cells functionality was different in tumor or non-tumor tissues of patients. Tissues were obtained from a large cohort of patients and were then analysed ex vivo. T cell populations were at different frequencies and different subtypes between tumor and non-tumor of the same patients. Further, the T cells infiltrating the tumor have an impaired proliferative ability compared non-tumor environment. The study confirms the TME is crucial to predict the effect of immune-modulatory therapies.
