PARP-1 activation has also been linked to Alzheimer’s (AD), Parkinson’s (PD) and ischemic stroke [19, 31, 51, 71, 72, 79], and the use of PARP-1/2 inhibitors is beneficial to mouse models of these diseases [2, 20, 25, 30, 87, 105, 109, 115]. The gene discussed is PARP1; the disease is Parkinson disease.
