Spinal cords were harvested 2 weeks following SCI-VEH or SCI-CBD treatment. SCI-CBD did not significantly decrease total CD45+ population (Figure 5A top left), microglia (bottom left), and macrophage (top right) population, but did significantly decrease CD4+ T cell population (bottom right). There were no significant differences in total spleen cell, T cell, or macrophage numbers in the spleens of CBD-treated versus vehicle-treated animals (Figure 5B) (n=6/group; tissues from three mice were pooled for each run, and the results from the two runs were averaged).
