The hot water extract of G. hansenii GK-1 (FII) inhibited the IL-4
production of spleen cells, but not that of ovalbumin (OVA)-specific
CD4+T cells, purified from food-allergic model mice. (A, B) Spleen cells
of OVA23-3 mice or (C, D) spleen CD4+T cells of R23-3 mice and
antigen-presenting cells prepared from spleens of BALB/c mice were stimulated with
G. hansenii GK-1 fractions (FI, FII, and FIII; final
concentrations 0.05, 0.2, 1, and 5 µg/mL) and OVA (final concentration 1 mg/mL). The
cells were cultured for 24 hr, and (A, C) IL-4 and (B, D) IFN-γ production in the
collected culture supernatant was measured by ELISA. The cells of 4 mice were
pooled, cultured and measured for 3 wells under each condition. Significance was
determined by Dunnett’s test for each G. hansenii GK-1 fraction vs.
without each G. hansenii GK-1 fraction (*p<0.05, **p<0.01,
#p<0.1). The data are representative of two independent
experiments.
