Distribution and cell types immunoreactive for HA-tagged ABCD1 after intrathecal delivery of rAAV9-CBA-hABCD1-HA. (a) Colocalization of HA tag with ABCD1 after rAAV9-CBA-hABCD1-HA transduction at 5 × 105 GC/cell in mixed glial cell culture. (b) Representative images show rAAV9-CBA-hABCD1-HA distribution across the whole spinal cord after IT pump and IT bolus delivery at 2 × 1011 GC/mouse. Higher magnification image shows punctate HA tag expression (HA, green) in glial cells and some neurons (NF, red). (c) Representative images show rAAV9-CBA-hABCD1-HA distribution across DRGs after IT pump and IT bolus delivery at 2 × 1011 GC/mouse. Higher magnification image shows punctate HA tag expression (HA, green) in DRG neurons (NF, red). (d) Cell types targeted in the spinal cord after IT delivery identified by costaining with various cellular markers including GFAP (astrocytes), IBA1 (microglia), NeuN (neurons), and Olig2 (oligodendrocytes) (HA, red). (e) Representative images show rAAV9-CBA-hABCD1-HA distribution in peripheral organs after IT pump and IT bolus delivery at 2 × 1011 GC/mouse. ABCD1, peroxisomal ATP-binding cassette transporter subfamily D member 1; DRG, dorsal root ganglia; GC, genome copies; GFAP, glial fibrillary acidic protein; HA, hemagglutinin; IBA1, ionized calcium binding adapter molecule 1; IT, intrathecal; NeuN, neural nuclei; NF, neurofilament; Olig2, oligodendrocyte transcription factor 2; SC, spinal cord.
