Ferritin-expressing lentiviral vectors were constructed in two steps. First, the FTH1 sequence was cloned into the pLVTHM vector between the MluI and ClaI sites, downstream of the H1p promoter, generating the pLVTHM-H1p-FTH1 plasmid vector. Second, one of three neural cell-specific promoter sequences (SYN1p, GFAPp, or MBPp) was cloned into the pLVTHM-H1p-hFTH1 vector between the EcoRI and MluI sites, replacing the H1p sequence, to generate three NDIFE vectors: pLVTHM-SYN1p-FTH1, pLVTHM-GFAPp-FTH1, and pLVTHM-MBPp-FTH1. FTH1: ferritin heavy chain, SYN1: synapsin I, GFAP: glial fibrillary acidic protein, MBP: myelin basic protein.
