Allison's notion of immune system "checkpoints" have led to new insights, which in turn promise new immune therapies for a wider range of malignancies, wrote Ribas.
Furthermore, cellular surveillance systems (checkpoints) that ensure genome integrity at several stages of the cell cycle are impaired in cancer cells [ 28, 29] and could fail to eliminate cells with extra copies.
Due to NHEJ's role as a DNA repair system and checkpoint activator, it is no surprise that there appears to be a connection between its malfunction and tumorigenesis in the brain.
Nothing, however ambitious or well funded, will work unless the Israelis get out of their checkpoints and, more fundamentally, unless the essentially punitive system the checkpoints serve is dismantled.
