导肽

除LPS外，CD14还介导肽聚糖（PGN）、脂磷壁酸（LTA）、脂蛋白等多种病原体成分与细胞的反应，它是天然免疫中重要的模式识别分子。

Thus , CD 14 is an important component of the innate immune system and can be defined as pattern recognition receptor .

它有一个由65个氨基酸残基组成的线粒体导肽，该导肽富含碱性氨基酸残基（如精氨酸）和疏水氨基酸残基（如丝氨酸和苏氨酸）。

The deduced protein contains a mitochondrial targeting presequence of 65 amino acids containing rich basic residues like arginine and hydroxy residues such as serine and threonine .

结论：分叉双歧杆菌的全肽聚糖能激活巨噬细胞，使之分泌多量的IL-6、IL-12及NO，这些细胞毒性效应分子介导了全肽聚糖的多种重要生理功能。

CONCLUSION : The result suggested that whole peptidoglycan of bifidobacterium bifidum could activate macrophages to secrete large amount of interleukin 6 , interleukin 12 and NO. These cytotoxicity effectors mediated many kinds of important physiological functions of bifidobacterium .
