An image that summarizes the relative functional responses of MSCs in the presence or absence of C albicans or T toxoid. The studies show APC properties heightened during a small window when IFNγ levels are less than 25 pg/mL. As IFNγ levels are increased, the efficiency of APC functions is decreased. Based on previous studies, the reduced efficiency could correlate with the MSCs switching roles as immune-suppressor cells.
