TRPM7 and Parkinson disease: Sun and his collaborators recently reported that apoptotic neuronal cell death induced by a Parkinson’s disease-related neurotoxin, MPP+, is protected by TRPM7 activation induced by isoproterenol (Sun et al., 2020a) and by TRPM7 overexpression (Sun et al., 2020b) in dopaminergic differentiated neuroblastoma SH-SY5Y cells.
