Acai PS induces TNF-α and NO in type A <i>F. tularensis</i>-infected RAW264.7 cells, but not in murine BMDMs.

Cells were treated and infected as in Table 1. 3/wells treatment at 20 hr post-infection shown; standard deviation in parentheses; results are representative of two independent experiments. aMean NO (µM) or bTNF-α (ng/ml) production. *p<0.05 as compared to the same cell type not treated with Acai PS. ∧p<0.05 as compared to the same cell type, with the same Acai treatment, treated with L-NMA at 20 hr post-infection. ND = not done.
