Caption: This image shows a 20um fixed-frozen horizontal section obtained through lamina I of the spinal cord, contralateral to site of brain injection. Fluorescence in FITC channel indicates expression of nuclear Sun1-GFP fusion protein in the presence of virally expressed cre recombinase. White arrows indicate GFP+ nuclei; the location and distribution are consistent with that of lamina I spino-PB projection neurons. Image taken on Olympus BX63 upright fluorescent microscope using 10X objective.

Age at Injection
62 days
Time After Injection
3 weeks
Detection Method
Direct fluorescence
Assay & Results
Robust and widespread expression at injection site in parabrachial nucleus. A moderate number of target cells (projection neurons in lamina I of the spinal cord) also expressed genetic cargo.
Target Cell Transduction
Nuclear GFP fluorescence was visible as expected following injection of the AAVrg-driven cre. So yes, the tool operated as expected, although the number of retrogradely transduced neurons was somewhat lower than expected.
Other Information
I also checked 2 weeks post-injection and found a similar pattern of expression, though the number of retrogradely transduced neurons was less than the three week timepoint
Tips & Comments
This is one of the better retrograde viruses I have tried, though the number of transduced target cells was still lower than desired. To improve results with this virus I would probably try to increase injection volume or use multiple injection sites.
