Bystander effect cells

WebThe radiation-induced bystander effect is defined as the response of cells to the consequences of their neighbors being irradiated and has been well characterized in vitro . There is a close interrelationship between bystander responses and the abscopal responses, which occur in tissues remote from the irradiation field and this is driven by ... WebFeb 6, 2024 · The bystander effect of extracellular MMAE was observed in cocultures of Karpas 299 or Ly540 cells in presence of SGN35 with CD30 - negative Burkitt lymphoma cells (Ramos). This effect is advantageous for the treatment of HL because of the heterogeneity of its cancer cells subsets: only a small fraction is CD30 - positive [ 49 , 50 ].
