摘要

Glatiramer acetate (GA) is an immunomodulator approved for therapy of relapsing-remitting multiple sclerosis (RRMS), but recent findings indicate that it may also have additional, neurotrophic effects. Here, we found that supernatants from human GA-reactive T lymphocytes potentiated oligodendrocyte numbers in rodent and human oligodendrocyte progenitor (OPC) cultures. Effects of Th2-polarized lines were stronger than Th1-polarized cells. Microarray and ELISA analyses revealed that neurotrophic factors induced in Th2- and Th1-polarized GA-reactive lines included IGF-2 and BMP-7 respectively, and functional studies confirmed IGF-2 as trophic for OPCs. Our results support the concept that GA therapy may result in supportive effects on oligodendrocytes in RRMS patients.
