WebNote that the bystander effect is not the same as the abscopal effect. The abscopal effect is a phenomenon where the response to radiation is seen in an organ/site distant to the irradiated organ/area, that is, the responding cells are not juxtaposed with the irradiated cells. T-cells and dendritic cells have been implicated to be part of the ... WebSep 21, 2004 · The bystander response was based on the production of micronuclei (MN) (a measure of chromosomal damage) in the cell population. The abundance of MN increased when a single T98G cell in the population was exposed to a single 3 He 2+ ion, and the bystander response occurred in T98G cultures and in cocultures with human …

WebClassical radiation biology research has centred on nuclear DNA as the main target of radiation-induced damage. Over the past two decades, this has been challenged by a significant amount of scientific evidence clearly showing radiation-induced cell signalling effects to have important roles in mediating overall radiobiological response.
