Abstract: | Bacillus為具有產孢能力的革蘭氏陽性菌,並且可當作益生菌來運用。根據先前的研究可知 Bacillus和其代謝產物可增強腸道相關淋巴組織之免疫反應。因此在本研究中,我們探討 B. licheniformis CK1是否可當作益生菌使用來改善腸道免疫系統。
於本研究中,首先藉由小鼠巨噬細胞株 RAW264.7 細胞來評估 B. licheniformis CK1免疫調節的能力,並於結果發現,B. licheniformis CK1及其個別細胞成分可活化 RAW264.7 細胞,並且亦可偵測到TNF- Bacillus spp. are Gram-positive spore-bearing bacteria and have for long been used as probiotics. Certain strains of Bacillus and their metabolites have been used for biotechnological applications or for improving a robust gut-associated lymphoid system (GALT). In this study, the improvement of intestinal immune system by probiotic Bacillus licheniformis CK1 was investigated. In the first part, the murine macrophage RAW264.7 cell was used to examine the immunomodulatory effects of B. licheniformis CK1. The results showed that intact cells or individual cellular fractions of B. licheniformis CK1 could activate RAW264.7 cells and increase the release of cytokines including tumour necrosis factor- |
