Effects of L. paracasei treatment on mRNA expression related to macrophage polarization in BMDM stimulated with LPS and IFN-γ. A) Hypoxia-inducible factor 1-alpha (HIF1A), B) inducible nitric oxide synthase (iNOS), C) arginase. PCR was performed using cDNA and the expression levels were normalized to HPRT. Samples without L. paracasei treatment were used as a control. Data are expressed as mean ± SEM of three independent experiments. Asterisks indicated a statistical significance (*, P < 0.05).
