ATG5 and amyotrophic lateral sclerosis: Furthermore, M1-TDP-43 PFFs-injected Atg5+/- mice showed abnormal spontaneous activity in both sides of biceps brachialis, T10 paraspinals, tibialis anterior, and gastrocnemius muscles at around 5 mpi, and C7-TDP-43 PFFs-injected Atg5+/- mice showed prolonged CMCT and decreased cMEP amplitude at around 2 mpi, which recapitulated the electrophysiologic changes found in ALS patients.
