Figure 6. Proliferative response to the S-antigen peptide in lymph node cells collected from rats treated with vehicle (n=4), low-dose fenofibrate (20 mg/kg, n=4), and high-dose fenofibrate (100 mg/kg, n=4) on day 28 post-immunization. The lymphocyte proliferation test demonstrated that high-dose fenofibrate treatment induced a decrease in lymphocyte proliferation in the presence of 25 mg/ml S-antigen (S-Ag) peptide compared with vehicle-treated groups. *p=0.0008 versus vehicle-treated group.
