  5. Oncolytic virus - Wikipedia

    en.wikipedia.org/wiki/Oncolytic_virus

    Attenuation involves deleting viral genes, or gene regions, to eliminate viral functions that are expendable in tumour cells, but not in normal cells, thus making the virus safer and more tumour-specific. Cancer cells and virus-infected cells have similar alterations in their cell signalling pathways, particularly those that govern progression ...

  6. Virotherapy - Wikipedia

    en.wikipedia.org/wiki/Virotherapy

    Oncolytic virotherapy is not a new idea – as early as the mid 1950s doctors were noticing that cancer patients who suffered a non-related viral infection, or who had been vaccinated recently, showed signs of improvement; [3] this has been largely attributed to the production of interferon and tumour necrosis factors in response to viral infection, but oncolytic viruses are being designed ...
