“Infectious diseases cause a rise in oxidative stress, which is largely responsible for coordinating our genetic response to the infection. As we age, mitochondrial respiration also causes a rise in oxidative stress, which activates essentially the same genes through a common mechanism that involves transcription factors like NFΚB. Unlike infections, however, ageing is not easily reversed: mitochondrial damage accumulates continuously. The stress response and inflammation therefore persist, and this creates a harsh environment for the expression of ‘normal’ genes. The expression of normal genes in an oxidized environment is the basis of their negative pleiotropic effects in old age”
