CDYL and infection: Neither the morphology (Supplementary Fig. 2g, h) nor resting membrane potentials (RMPs) of neurons were changed with CDYL-shRNA infection (CDYL-shRNA infected neurons RMP, −77.91 ± 0.58, n = 34; nonsilencing-shRNA infected neurons RMP, −77.23 ± 0.89, n = 20; non-infected neurons RMP, −78.08 ± 0.48, n = 33) (Supplementary Table 1).
