| 简介 | 自然杀伤细胞(natural killer cell,NK)是机体重要的免疫细胞,不仅与抗肿瘤、 抗病毒感染和免疫调节有关,而且在某些情况下参与超敏反应和自身免疫性疾病的发生。一种稳定表达在NK和LAK细胞表面的LAK-1分子,120kDa,NK细胞在IL-2条件下培养20天LAK-1仍为阳性,而HNK-1(CD57)和CD16部分消失。LAK的杀伤活性可被抗LAK-1 McAb所抑制,自然杀伤细胞刺激因子(natural killer cell stimulatory factor,NKSF) 对NK细胞有刺激作用。IL-2、IL-12、IFN-α、TNF-α以及白细胞调节素(leukoregulin,LR) 对NK细胞的活化和分化有正调节作用, 体外培养时加入上述细胞因子可明显提高NK的杀伤活性。前列腺素 (PG)E1、E2、D2和肾上腺皮质激素等对NK细胞的活性有抑制作用。 |

/content/abstract/206/10/2235 【内容简评】 Biron领导的研究组证实:NK细胞在没有细胞毒性时,激活性Ly49H受体能促进其增殖。增殖的NK细胞通过调节IL-10的产生及随后抑制具有免疫病理性的CD8T细胞,而达到调节被动免疫的目的。 人们已经知道NK细胞激活受体多数情况下与诱导先天性免疫有关,包括细胞毒性T淋巴细胞反应和NK细胞增殖。Biron利用MCMV感染的Ly49H & perforin单敲除或双敲除小鼠作为模型,发现NK细胞以Ly49H和IL-10依赖

新冠肺炎中的NK细胞功能障碍(dysfunction)及策略 1. COVID-19的免疫学特征 新冠病毒感染疾病(COVID-19)这场持续存在的大流行在全球范围已感染数亿人口,而且造成了数百万人口的死亡。SARS-CoV-2 感染在大多数情况下的特征是发热、疲倦和干咳等轻度症状。在极少数情况下,可以导致严重的并发症,如细胞因子释放综合征(CRS),噬血细胞淋巴组织细胞增多症(HLH)和急性呼吸窘迫综合征(ARDS),这些严重并发症在老年人中更常见,尤其是心血
结合成抗原抗体复合物时,此时IgG 的FC段与K细胞膜上的Fc,受体结合;从而触发K细胞的活性使靶细胞受到损伤,致使细胞内成分漏出,最后导致靶细胞裂解。可见K 细胞的杀伤作用必须依赖于特异性抗体(IgG)作为桥梁,故称为抗体依赖性细胞介导的细胞毒作用。K细胞在人体中具有抗某些肿瘤及病毒性感染的作用,也在清除自身衰残细胞方面发挥一定作用。 NK细胞是natural killer ce11的缩写;通称自然杀伤细胞。NK细胞在体内的分布较广。实验证明,NK细胞在小鼠的外周血中数量最多
