Fig 2: Effects of cannabidiol or GILZ on CB2-positive kidney cells. Kidney cell preparations from experimental groups, as described under Methods, were subjected to flow cytometry analyses for CB2 expression. (a, c) Representative histograms while bar graphs (b, d) show quantitative data for CB2-positive cells for experimental groups. Data are means ± SEM, 4-5 animals (CBD and vehicle conditions) and 6 animals (TAT and TAT-GILZ conditions) for each group; each independent experiment included 3-6 animals. *p < 0.05 compared to other three groups.
