Fig. 4. Inhibitory effects of gamma-aminobutyric acid (GABA)-salt on the expressions of type 1 macrophages (M1) and associated cytokines in vitro. (A, B) qRT-PCR graph showing the mRNA expressions of M1 and M2 macrophage marker in media, salt or GABA-salt treated Raw 264.7 cells. (C, D) qRT-PCR graph showing the mRNA expressions of M1 (TNF-α) and M2 (TGF-β) macrophage marker in media, salt or GABA-salt treated Raw 264.7 cells. (E, F) qRT-PCR graph showing the mRNA expressions of M1 (iNOS) and M2 (Arg-1) macrophage marker in media, salt or GABA-salt treated Raw 264.7 cells. NS, not significant compared to salt. *p < 0.05 vs. media; $p < 0.05 vs. salt.
