The immune system continuously scans our body to detect any dysfunction. However, during pathological processes, the immune system may become deficient. This is notably the case for certain cancers where strong immunosuppression takes place.
To alleviate this problem, immunotherapies aiming to reactivate the immune system are developed. Some of these therapies have allowed for spectacular progress in cancer treatment (melanoma, lung cancer, etc.). They allow the reactivation of immunosuppressed T lymphocytes, but only work for 10 to 40% of patients.
