Abstract:
In murine models of cancer, we have achieved efficient systemic activation of tumor-specific T cells by the local administration of a CTLA4-blocking antibody at low doses. Using a slow-release formulation, we could drastically lower the serum levels of the antibody, hence decreasing adverse effects and the risk of autoimmune reactions, without losing systemic efficacy.

Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
