Figure 1From: Differential adeno-associated virus mediated gene transfer to sensory neurons following intrathecal delivery by direct lumbar puncture Mannitol enhances GFP expression in mouse spinal cord and DRG. Sections are from mice perfused six weeks after i.t. injection of rAAV5-GFP with or without intravenous mannitol pretreatment. A) GFP immunoreactivity (-ir) in the spinal cord of a mannitol-pretreated mouse. B) GFP-ir in spinal cord of a saline-pretreated mouse. C) GFP-ir in L4 DRG of a mannitol-pretreated mouse. D) Mannitol pretreatment significantly enhances transduction of lumbar DRG neurons when compared to saline pretreatment; Mann-Whitney, U05(1),3,3 = 9, p = 0.05.Back to article page
