Figure Lengend Snippet: a Primary cortical neurons were isolated from neonatal mice (P0–P1) and induced to differentiate in vitro. On day 7 of differentiation, neurons exhibiting neurite outgrowth were observed under bright-field microscopy. Confocal imaging showed neuronal nuclei stained with DAPI (blue), and endogenous Neun labeled with an anti-Neun antibody (red). Scale bar = 50 μm. b , c WT and Disc1 KD primary cortical neurons were pre-incubated with 20 μg/mL MAR1-5A3 for 6 h, followed by infection with ZIKV at a MOI of 1. Viral mRNA levels and titers were measured on D1 and D2 post-infection using qRT-PCR ( b ) and plaque assay ( c ). d WT and Disc1 KD primary cortical neurons were pre-incubated with 20 μg/mL MAR1-5A3 for 6 h, followed by infection with ZIKV at a MOI of 1. The protein levels of ZIKV E protein, DISC1, AMPKα, pAMPKα, mTOR, pmTOR, P62 and LC3A/B were assessed by Western blot on D1 and D2 post-infection. e, f The ratios of pAMPKα to AMPKα ( e ) and pmTOR to mTOR ( f ) were determined by comparing the corresponding protein band intensities at each time point in Fig. 8d. g − i Quantification of P62 ( g ), LC3A/BⅠ ( h ) and LC3A/BⅡ ( i ) protein levels relative to GAPDH at each time point in Fig. 8d. j , k Placentas ( j ) and fetal heads ( k ) from non-infected and ZIKV-infected WT and Disc1 KD mice were collected on E13.5. The protein levels of DISC1, AMPKα, pAMPKα, mTOR, pmTOR, P62 and LC3A/B were assessed by Western blot. l − o The ratios of pAMPKα to AMPKα ( l, m ) and pmTOR to mTOR ( n , o ) were determined by comparing the corresponding protein band intensities at each time point in Fig. 8j ( l, n ) and Fig. 8k ( m , o ). p − s Quantification of P62 ( p , q ) and LC3A/BⅡ ( r , s ) protein levels relative to GAPDH at each time point in Fig. 8j ( p , r ) and Fig. 8k ( q , s ). Data shown in ( b , c ) are from one representative experiment out of three independent replicates with similar results, each including 3 biological replicates per group ( n = 3). Images in ( a , d , j – k ) are from one representative experiment out of three independent replicates with similar results ( n = 3). Data shown in ( e − i , l − s) are collected from three independent experiments ( n = 3). Data shown in ( b − c , e − i , l − s ) were confirmed to follow a normal distribution using the Shapiro-Wilk test, and statistical analysis was performed using Student’s unpaired two-tailed t test ( b , c ) or two-tailed one-way ANOVA followed by Tukey’s multiple comparison test ( e − i , l − s ). Data are presented as means ± SD. Source data are provided as a Source Data file.
