  • Title: Conversion of peripheral CD4(+)CD25(-) T cells to CD4(+)CD25(+) regulatory T cells by IFN-gamma in patients with Guillain-Barré syndrome.
    Author: Huang S, Li L, Liang S, Wang W.
    Journal: J Neuroimmunol; 2009 Dec 10; 217(1-2):80-4. PubMed ID: 19853929.
    Abstract:
    CD4(+)CD25(-) T cells from 25 Guillain-Barré syndrome (GBS) patients were stimulated by IFN-gamma to generate the induced CD4(+)CD25(+) regulatory T cells (iTregs). Then, their phenotypical and functional characterizations were analyzed. Results show that iTregs can be generated from CD4(+)CD25(-) T cells in GBS patients by IFN-gamma in the presence of activating anti-CD3 and anti-CD28 antibodies in vitro. When CD4(+)CD25(-) T cells are stimulated by 40ng/ml IFN-gamma for 3days, the ratio of conversion is the highest under this condition and iTregs are similar to naturally occurring CD4(+)CD25(+) regulatory T cells of healthy donors phenotypically and functionally.
