"This raises the question of why so many pathways that react to the challenge of infection or tissue injury use mitochondria as a central signalling hub to integrate and transduce the cell’s response. One probable factor is that the endosymbiotic origin of mitochondria marks them apart from the rest of the cell in a way that can be co-opted to produce key messages pertaining to cell fate"
