SOD1 and amyotrophic lateral sclerosis: Interestingly, axonal degeneration and motor dysfunction have been found to reduce in SOD1 G93A transgenic mice on silencing of RIPK3 or Nec-1 (7–Cl–O–Nec-1) stimulation [89] and suggested that astrocytes in motor neuron of ALS patient stimulate necroptosis in RIPK1/MLKL-dependent manner.
