Model | Strain Used in Fermentation | Action Mode | Reference |
---|---|---|---|
RAW264.7 macrophage |
B. subtilis | Increasing levels of functional polysaccharides Activating mRNA expression of nitric oxide (NO) synthase and tumor necrosis factor-α (TNF-α) by inducing nuclear factor-kappa B (NF-κB) → increased production of NO and TNF-α |
[126,127] |
Mast cells | – | Inhibiting allergen permeation through paracellular diffusion into epithelial cells; suppressing Th2 cells-related cytokine production by modulating Th1/Th2 homeostasis; inhibiting CD4+ T cell differentiation by activating regulatory T cells (Treg); inhibiting degranulation of mast cells | [128] |
Male C57BL/6 mice |
B. amyloliquefaciens CJ3-27 B. amyloliquefaciens CJ1526 B. subtilis CJ1553 |
Enhancing T helper type-1-mediated immune response by upregulating production ratio of IFN-γ vs. IL-4 and IgG2a vs. IgG1 in T and B cells; improving enhanced splenic natural killer cell activity → activating humoral and cellular immunity to Th1 response | [129] |
Human primary immune cells | – | Modulating isoflavone-derived immunostimulatory activity by enhancing cell proliferation, nitrite, and transcriptional activation of TNF-α, IL-6, iNOS, and COX-2 gene | [130] |
Male BALB/cByJ mice | B. subtilis | Improving lymphocyte proliferation, natural killer cell activity, and white blood cell population through activation of NO and immunostimulatory cytokines (IL-6 and IL-12) | [126] |
MCF7 cells | B. licheniformis B1 | Decreasing growth of breast cancer MCF7 cells via upregulation of TGFβ1 and SMAD3, downregulation of inflammation-related genes (CSF2, CSF2RA, and CSF3), and differential expression of the genes encoding chemokines (CCL2, CCL3, CCL3L3, CXCL1, and CXCL2) → preventing breast cancer by TGFβ-dependent signaling mechanism and inhibiting inflammation | [131] |
ICR mice |
B. subtilis MC31 L. sakei 383 |
Not inducing any specific toxicity in liver and kidney organs ICR at dose 100 mg/kg body weight/day as no observed effect level | [132] |
