Stimulus (polyphenol, IFN-γ, LPS)-dependent nitric oxide production and antileishmanial effects in RAW 264.7 macrophages

The effects of IFN-γ, LPS and some polyphenols as individual stimuli as well as in various combinations on the NO production in non-infected and infected macrophage-like RAW 264.7 cells were investigated, with emphasis on the NO/parasite kill relationship.
