Article Title: Cannabidiol (CBD) Induces Functional Tregs in Response to Low-Level T Cell Activation
doi: 10.1016/j.cellimm.2016.11.006
Figure Lengend Snippet: Splenocytes were treated with CBD (5 or 10 μM) or VH (0.1% ethanol) for 30 min followed by low-level stimulation. (A) Cells were stimulated with S/o or Us/o stimulation for 1, 3 or 5 days. IL-2 was assessed by ELISA. Data are average of triplicate wells ± SD with * p < 0.05 as compared to VH within group; # p < 0.05 as compared to Day 1. (B, C) Cells were stimulated with S/o (B) or Us/o or s3/CD28 (C) for 1 day. Cells were treated with BFA for the last 4 hr of culture then stained for viability, CD4, IL-2 and TGF-β1. Numbers above plots are average percent gated numbers ± SE of triplicate results for the quadrant. Dot plots represent triplicate results of at least three separate experiments. Cells are gated on live CD4+ cells. * p < 0.05 as compared to VH within each stimulation group. Stim, stimulated.
Article Snippet: In some experiments, CD4 + T cells were enriched from splenocytes by negative selection using a mouse T cell CD4 subset column kit (R&D Systems, Minneapolis, MN) according to the manufacturer's instructions.
