PG - 313-31 AB - Sixty, relapsing remitting (RR) multiple sclerosis (MS) patients, who underwent treatment with glatiramer acetate (GA), interferon (IFN)-beta 1a, and immunoglobulins (Igs) (20 per treatment group), were assessed for levels of brain-derived neurotrophic factor (BDNF) in the supernatants of unstimulated and stimulated peripheral blood mononuclear cells (PBMCs) in the first year of treatment. Phytohemagglutinin (PHA), anti-OKT3 antibody, myelin basic protein (MPB) and GA were used as stimuli. Cytokine responses by ELISPOT and lymphoproliferative responses were also assessed. The GA-treated MS patient group showed a progressive increase in BDNF levels, from baseline to month three; thereafter, the levels remained stable and significantly greater compared with baseline and controls (ANOVA=P<0.001). IFN-beta 1a had no effect on BDNF production, whereas Igs induced a slight decrease (ANOVA=P<0.04). ELISPOT analysis revealed a significant decrease of IFN-gamma, an increase of interleukin (IL)-4 and IL-5 in GA-treated MS patients, and an increase of IL-10 in patients treated with IFN-beta 1a and GA. No significant correlation was found between BDNF secretion in the supernatants of PBMCs and cytokine response, lesional load, and measures of atrophy. Increased BDNF production related to GA treatment can have implications for understanding the mechanism of action of this immunomodulatory agent, in light of evidence suggesting its effects in promoting neuroprotective immunity in MS patients; however, a clinically measurable effect, especially in terms of an impact on actual disease progression, remains to be established.
