A notre système immunitaire de tuer les cellules cancéreuses

Utiliser les défenses naturelles de l’organisme pour lutter contre le cancer est le principe de l’immunothérapie. Une voie de traitement très prometteuse qui a déjà fait ses preuves. Le sujet était au centre d’un congrès des instituts européens qui s’est tenu à Bruxelles. Eclairage.

T lymphocytes and cancer cell. Coloured scanning electron micrograph (SEM) of T lymphocyte cells (smaller round cells) attached to a cancer cell. T lymphocytes are a type of white blood cell and one of the components of the body's immune system. They recognise a specific site (antigen) on the surface of cancer cells or pathogens and bind to it. Some T lymphocytes then signal for other immune system cells to eliminate the cell. Cytotoxic T lymphocytes eliminate the cell themselves by releasing a protein that forms pores in the cell's membrane. The genetic changes that cause a cell to become cancerous lead to the presentation of tumour antigens on the cell's surface. Magnification: x1000 at 10 centimetres wide. Reporters / Science and Photo

Et si, un jour, on arrivait à combattre le cancer rien qu’en utilisant l’immunité même du patient ? Se servir des défenses naturelles de l’organisme pour tuer les cellules...
