采用流式细胞术检测脐血,母亲及对照组中NK细胞和CD56brightCD16dim/-NK细胞亚群的比率.结果脐血中淋巴细胞计数显著高于母亲及对照组;NK细胞比率无显著性差异;CD56brightCD16dim/-NK细胞高于母亲及对照组;母亲组CD56brightCD16dim/-NK细胞高于对照组.结论脐血中丰富的CD56brightCD16dim/-NK细胞是脐血低免疫应答的原因...
结论 脐血中丰富的 CD56bright CD16dim/-NK细胞是脐血低免疫应答的原因之一。关键词:脐血; NK细胞;CD56bright CD16dim/-NK细胞中图分类号: R392.11文献标识码: AThedetectionofCD56brightCD16dim/-subsetNKcellsinUmbilicalCordBlood SUN Jian,CHEN Jun-hao,ZHANGKui.(Department of Laboratory,Gulou Affiliated ...
•CMV/EBV双重感染组CD56neg NK细胞比例升高更为显著•CD56neg NK细胞的增多伴随着CD56dim NK细胞数量的减少•单独CMV或EBV感染组未见CD56neg NK细胞明显增加 2、CD56阴性NK细胞功能受损。功能实验显示CD56neg NK细胞相比于CD56dim NK细胞: •对K562靶细胞的裂解能力降低约40%•CD107a表达水平降低50-60%...

Among NK cells, CD56bright CD16neg (cytokine-producing) NK cells are less cytotoxic and produce more cytokines, whereas CD56dim CD16+ (cytotoxic) NK cells are more cytotoxic and produce fewer cytokines (5). A highly dysfunctional population of NK cells (CD56neg CD16+) has been described in...
NK细胞分哪两个亚群?()A.CD16dim和CD16Bright;B.CD56dim和CD56Bright;C.D56dim和CD16Bright;D.CD16dim和
Therefore, we found that a synergistic effect of the right and left leg muscle strength was associated with proportion of matured NK and NKT cells and induced a low proportion of CD56brightCD16−cells within lymphocyte. Moreover, the low proportion of CD56brightCD16−cells was associated ...
自然杀伤(nature kill,NK)细胞无需抗原预先致敏即可直接杀伤靶细胞,其发挥免疫效应早于T淋巴细胞,因此被视为机体免疫防御的第一道防线.但近年越来越多的研究表明CD56bright CD 16dim NK细胞亚型在肿瘤的生物学作用中扮演“帮凶”角色,现将近年关于CD5 6bright CD 16dim NK细胞在在肿瘤中发挥的效应综述如...
