免疫细胞(immune cell)俗称白细胞,主要包括各种淋巴细胞和吞噬细胞,如T细胞,B细胞,NK细胞,巨噬细胞,DC细胞等。每种主要类型又包含很多种亚群。体内的免疫细胞亚群有数十种,我们研究比较清楚的只有十余种。 肿瘤细胞来源于正常细胞的突变,是潜伏在人民内部的敌人,很难被免疫系统识别和清除。在众多的免疫细胞亚群中,常规认为,杀伤功能的细胞是NK细胞和CD8 T淋巴细胞。 最近

肿瘤细胞来源于正常细胞的突变,是潜伏在人民内部的敌人,很难被免疫系统识别和清除。在众多的免疫细胞亚群中,常规认为,杀伤功能的细胞是NK细胞和CD8 T淋巴细胞。

最近,清华细胞研究所研究团队发表在Scientific Reports上的最新研究成果证实,免疫系统里还有一种特殊杀伤细胞---NKT,它是免疫系统中的特种兵,它的数量稀少,只占到免疫细胞的百分之一。

这种CD8+NKT细胞既表达T细胞的标志物TCRβ和CD3,同时也表达NK细胞受体NK1.1, CD49b,NKG2D。与传统的CD1d依赖的NKT细胞不同,这种CD8+NKT样细胞能处理g化的TCRs,分泌高水平IFNγ,而不是IL-4.在CD1d基因敲除的小鼠中,CD8+NKT细胞发育是正常的,表明它的发育不依赖CD1d,可能有独特的机制。就功能而言,这种CD8+NKT具有抑制T细胞反应的作用,其主要机制消除DC细胞。这种机制在机体免疫平衡中起关键性作用。

这是团队NKT系列研究的第一个成果,也是首次曝光这种神秘细胞。该项研究首次提出免疫系统具有抗原特异性主动负相调节的能力, NKT可以通过快速杀伤、清除带有抗原的DC,实现对特异性免疫反应的及时、快速、有效和精准的主动调控,防止全体出现免疫过激,造成免疫损伤。这种强悍的细胞对病毒感染的病变细胞和肿瘤细胞,也可能会展示巨大的杀伤威力。

小知识:

NKT(natural killer T)细胞是一群细胞表面既有T细胞受体TCR,又有NK细胞受体的特殊T细胞亚群。

KT细胞能表达T细胞的TCR与NK细胞的NKR-P1两种受体,特别是NKT细胞多数表达Va14TCR,识别CD1抗原,而NKR-P1识别各种糖链。 NKT细胞,特别是CD4-NKT细胞,对TCR刺激可产生大量IL-4及IFNγ,同时具有ThO型细胞因子产生能力。NKT细胞不但产生IL-4的主要细胞,而且强力产生IFNγ。IFNγ参与自身Th1诱导,具有极强的Th1诱导能力,从而是IL-2产生亢进。它同时还具有Th2细胞分化抑制功能。IL-12能诱导NKT细胞产生IFNγ。IL-12对TCR的刺激是IFNγ的产生显著亢进。综上所述,NKT细胞不但是IL-4和IFNγ的强力产生细胞,同时参与Th1/Th2分化的抑制,而这些作用都不是单纯的。

虽然NKT细胞能大量产生细胞因子,但仅在机体内保持这种功能。当初一度认为,NKT细胞只是IL-4的产生细胞,而不是Th2分化的必需细胞。并不认为在CD1缺损的小鼠中NKT细胞的分化和对TCR刺激使IL-4产生减少,且对Th2分化必需的IL-4及IgE的产生没有多大影响。但给小鼠投于α-GalCer可使NKT细胞活化,IL-4的产生诱导Th2的应答。有报告指出,同样投于α-GalCer,可使NKT细胞产生IFNγ而致IgE产生低下。由此可见,NKT细胞能产生IL-4与IFNγ两种功能相反的细胞因子。这种微妙的协调作用可能是NKT机能表达的重要特征。NKT细胞的活化通常伴有T细胞、B细胞及NK细胞的活化,这对NKT细胞活化后的免疫应答有较大影响。

其主要特征为:

1.共表达T细胞受体和NK细胞受体。经典NKT细胞一般为CD4+和DN NKT细胞。其中NK1.1是NKT细胞最主要的表面标记。

2.TCR基因偏向性取用(bias usage)。与其它T细胞亚群相比,NKT细胞具有独特的限制性表达TCR库。

3.接受CD1d递呈的脂类抗原,在固有免疫中发挥作用。

NKT细胞的生物学功能

主要包括免疫调节和细胞毒作用,NKT细胞受到刺激后,可以分泌大量的IL-4,IFN-γ,GM-CSF,IL-13和其它细胞因子和趋化因子,发挥免疫调节作用,NKT细胞是联系固有免疫和获得性免疫的桥梁之一。NKT细胞活化后具有NK细胞样细胞毒活性,可溶解NK细胞敏感的靶细胞,主要效应分子为穿孔素,Fas配体以及IFN-γ。
通常认为,构成机体免疫系统的淋巴细胞有三种细胞系组成,一是由胸腺产生的T细胞,二是由骨髓分化而来的产生抗体的B细胞,三是自然杀伤细胞(NK细胞)。而新近发现存在第四种淋巴细胞—NKT细胞。

NKT细胞的发现1986年,克隆成功了NKT细胞的特征性抗原受体基因。将其命名为Va14基因,与其他T细胞抗原受体的(TCR)基因不同,有其独特的结构特征。1987年美国国立卫生研究所的Fawlkes与瑞士的Budd分别领导的两个研究小组报告指出,胸腺细胞中的T细胞通常不能表达受体,仅有部分未成熟T细胞选择表达V-β8.2受体。随后的研究证明这种细胞不是T细胞,考虑是NK细胞的受体,这种细胞集团的数量极少,生理意义不明。1994年,这两个研究小组的研究人员发现,他们报道的细胞为同一细胞,从此NKT细胞的研究引起人们的广泛关注。

免疫功能

1、T细胞识别的抗原是蛋白质,而NKT细胞识别的抗原是α-Gal-Cer即所谓的糖脂质,这是该免疫系统与通常的免疫系统重要的不同点。NKT细胞的分化与T细胞不同的是在胸腺形成前的胎生初期6.5日在胸腺外组织分化。NKT细胞与T细胞比较,机能处于不发达状态。T细胞分化为功能不同的Th1和Th2细胞群,Th1细胞产生INFγ及IL-2,引起迟发行过敏症等细胞性炎症。Th2细胞能产生IL-4和IL-10,参与变态反应及抗体产生等体液免疫反应。而NKT细胞不但能分泌Th1和Th2细胞因子,同时还具有与CD8+杀伤性T细胞(cytotoxic T lymphocytes, CTL)相同的杀伤靶细胞作用。毫无疑问,NKT细胞在免疫调节系统中占有重要位置。NKT细胞与疾病可能有诸多关系,可能与自身免疫性疾病的发病机制、变态反应的调节、抗肿瘤作用、及抑制寄生虫感染等有关。
NKT细胞与CD4细胞共同作用

2. NKT细胞的多样性分化[4~7]NKT细胞具有T细胞和NK细胞细胞两重性质,既能表达Va14/Ja281特定的T细胞受体又能由CD1介导识别脂质抗原。NKT细胞的分化是否依赖胸腺尚有争议。根据其表达TCR等多种表面抗原的不同,提示NKT细胞存在两个以上细胞群。从CD4/8的表达看,可将其分为(1)CD4-NKT细胞,(2)CD8-NKT细胞,(3)CD4和CD8均不能表达的DN-NKT细胞。第一类的全部和第二类的半数是Va14/Ja281-T细胞。

3.人类NKT细胞人末梢血中的DN-NKT细胞V区域,可高度表达Va24/JaQ(这与鼠的Va14/Ja281高度相似)及Vβ11(与鼠Vβ18高度相似)。这种TCR的组合表达可见于DN-NKT细胞和CD4+细胞。而未见于CD8+细胞。小鼠的CD1相当于人的CD1d的Va24/JaQ。此外,人末梢血中1~2%的T细胞能表达抑制性受体,即抑制型NK细胞受体(KIR),而Va24/JaQ+细胞则不能表达。它的NK相关分子是CD16、CD56或CD57,Va24/JaQ+细胞异不能表达这些分子。在小鼠中还可以看到Va24/Ja281+T细胞以外的NKT细胞。人类Va24/JaQ+细胞与KIR+T细胞能形成不同的亚群。且具有不同的功能。

4. NKT细胞分化的胸腺依赖性这是目前存在争议的问题,可以肯定地说NKT细胞分化过程中胸腺是有作用的。NKT细胞多见于胸腺及脾脏以外的肝脏和骨髓种,胸腺缺损的小鼠与正常小鼠比较,NKT的分化并不少。将出生三日小鼠的胸腺摘除,虽然NKT细胞的分化显著受到抑制,但此时CD8+NKT细胞的分化未受到影响。由此认为CD8+NKT细胞在胸腺外分化的可能。

5. NKT细胞产生细胞因子的意义 NKT细胞是指能够表达NKT细胞标志NKT1.1的T细胞,其机能具有T细胞和NKT细胞双重特征。NKT细胞在TCR和NKR介导下,产生大量的IL-4及INFγ,对肿瘤细胞有杀伤作用。

盘点:单克隆抗体疗法亮点研究一览

单克隆抗体是由单一B细胞克隆产生的高度均一、仅针对某一特定抗原表位的抗体;通常采用杂交瘤技术来制备,杂交瘤抗体技术是在细胞融合技术的基础上,将具有分泌特异性抗体能力的致敏B细胞和具有无限繁殖能力的骨髓瘤细胞融合为B细胞杂交瘤;用具备这种特性的单个杂交瘤细胞培养成细胞群,可制备针对一种抗原表位的特异性抗体即单克隆抗体。 单克隆抗体一直被认为对人类癌的诊断和治疗有很高的价值,原因在于其能与
