Magnesium isoglycyrrhizinate (MGL) is a new stereoisomer of glycyrrhizic acid,
which is clinically used as a hepatoprotective medicine with more potent effects
and less side effects than glycyrrhizic acid. This study was designed to evaluate
the protective effects and possible mechanism of MGL against concanavalin A (Con
A)-induced autoimmune hepatitis. Hepatitis was induced by Con A in C57/6J mice
with or without MGL administration; injury score and serum ALT were evaluated.
The CD4(+) T-cells were isolated from splenocytes and challenged with Con A after
coculturing with MGL. The injury score was significantly improved in MGL-treated
mice after Con A challenging for 12 and 24 hours compared with those merely
challenged with Con A. Similar trends were observed in the serum levels of ALT
and AST. The most interesting result was that MGL administration significantly
decreased the frequency of CD4(+)CD25(-)CD69(+) T-cells rather than
CD4(+)CD25(+)CD69(+) T-cells in peripheral blood mononuclear cells, after Con A
challenging 12 and 24 hours. Moreover, the serum ALT levels were markedly
correlated with the frequency of CD4(+)CD25(-)CD69(+) cells, but only weakly
correlated with CD4(+)CD25(+)CD69(+) cells in peripheral blood mononuclear cells.
More importantly, MGL (5 mg/mL) almost completely eliminated the proliferation of
the CD25(-)CD69(+) subset in primary CD4(+) T-cells after Con A challenge.
Compared with merely Con A-challenged mice, those with MGL administration
significantly demonstrated decreased NALP3, NLRP6, and caspase-3 expression, in
which the NALP3 and caspase-3 downregulated in a dose-dependent manner. Our
results indicate that MGL may have potential as a therapeutic agent in autoimmune
hepatitis by ameliorating liver injury. Its molecular mechanism may be involved
in inhibiting CD4(+)CD25(-)CD69(+) subset proliferation and downregulating
inflammasome expression in liver tissue.
