Cancer-killing T cells have been programmed to have two levels of specificity. First, the T cells have been equipped with a receptor sensitive to a protein that is found only in central nervous system (CNS) tissue.

Tumor cell deaths can benefit tumors. A paradox? Not at all. If, for example, a dying tumor cell undergoes necroptosis, it can release inflammatory factors that can enhance or diminish antitumor immunity. Consequently, the idea of relying on necroptosis, an inflammatory form of cell death, as an alternative or adjunct to apoptosis, a non-inflammatory form of cell death, needs to be pursued with all due caution.

Molecular instructions in living cells can be timed rather like the notes or chords in a piece of music. For example, a finite number of genes can be activated and expressed in different orders, for different durations, to permit the assembly (or disassembly) of different polymers.

A mature cell of one type can be turned into a mature cell of another type without the cell having to pass through an earlier stage of development. This is called direct reprogramming, a reliable but notoriously inefficient process. Apparently, direct reprogramming occurs in only a few cells in a cell population. But which cells?
