Numbers of IFN-γ-secreting cells per 105 lymph node mononuclear cells (MNC) at day 27 post-immunization from experimental autoimmune neuritis (EAN) rats treated with Linomide (1.6, 16 and 160 mg/kg per day) and controls, after ex vivo culture without antigen or mitogen, and in the presence of phytohaemagglutinin (PHA), bovine peripheral nerve myelin (BPM) and P2 peptide, respectively. Means and s.d. are indicated. P values refer to comparisons between EAN rats treated with Linomide and PBS-treated control EAN rats. *P < 0.05; **P < 0.01; ***P < 0.001.
