Transcript
Lâun des traitements ciblĂ©s contre le cancer les plus efficaces est basĂ© sur des anticorps tels que lâanticorps anti-HER2 trastuzumab. Lâaction anticancĂ©reuse du trastuzumab implique une cytotoxicitĂ© Ă mĂ©diation cellulaire dĂ©pendante des anticorps

Summary
Ici, nous prĂ©sentons une mĂ©thode pour identifier les composĂ©s qui modulent le mĂ©canisme ADCC, un mĂ©canisme important de destruction des cellules cancĂ©reuses des anticorps antitumoraux. Lâeffet cytotoxique des cellules NK est mesurĂ© dans les sphĂ©roĂŻdes des cellules cancĂ©reuses du sein en prĂ©sence de trastuzumab. Lâanalyse dâimages permet dâidentifier les cellules tueuses et cibles vivantes et mortes dans les sphĂ©roĂŻdes.
