pro-inflammatory cytokines from the murine monocyte cell line, Raw 264.7 and from C57 BL/6 mouse peritoneal macrophages following exposure to the saccharide analog. Our data conclude that the novel saccharide has immunostimulatory activity on mouse macrophages as indicated by the elevated levels of IL-6 and TNF-α in culture supernatants. This effect was TLR-4-dependent but TLR-2-independent. Our data, suggest TLR-4
由于缺乏FDA批准的佐剂,因此有必要合成,表征新化合物并将其用作疫苗佐剂。为此,已经从

糖类似物,并在先天免疫细胞中确定了其
生物学功效。更具体地说,我们评估了暴露于

细胞系Raw 264.7和C57 BL / 6小鼠腹膜巨噬细胞促炎细胞因子的产生。我们的数据得出结论,如培养上清液中IL-6和TNF-α的
水平升高所表明,这种新型
糖类对小鼠巨噬细胞具有免疫刺激活性。该效应是TLR-4依赖性的,但与TLR-2无关的。我们的数据表明TLR-4激动;疫苗佐剂的关键特征。
