Abstract

Bone marrow-derived mesenchymal stem cells (bMSCs) can differentiate into a number of different cell/tissue types, and also possess immunoregulatory functions. The present study was undertaken to elucidate the exact immunoregulatory effects of allogeneic bMSCs on T- and B-lymphocyte proliferation, activation, and function maturation of BXSB mice, which has been considered as a experimental model for human systemic lupus erythematosus (SLE). We determined that bMSCs from BALB/c mice had inhibitory effects on BXSB mice T-lymphocyte proliferation, but no inhibitory effect on their activation. In addition, they had a significant inhibitory and stimulatory effect on IL-4- and IFN-gamma-producing T cells, respectively. Also, bMSCs had inhibitory effects on the proliferation, activation, and IgG secretion of B lymphocytes. In addition, BALB/c bMSCs had an enhancing effect on CD40 expression and inhibitory effects on CD40 ligand (CD40L) ectopic hyperexpression on B cells from BXSB mice.
