Fig. 3From: 5-Aminolevulinic acid regulates the immune response in LPS-stimulated RAW 264.7 macrophagesALA-treatment significantly reduced NO2− expression in RAW264.7 macrophages stimulated by LPS. NO2− expression levels of RAW264.7 were tested after incubation with several conditions of (a) LPS or (b) ALA with 1000 ng/mL LPS.
