自身免疫

Most of these cells are clonally deleted in the bone marrow, but some of these cells avoid deleting and escape to periphery by anergy and produce autoantibody.

但有些B细胞通过免疫无力的方式逃脱了这种克隆删除到达外周，产生抗自身的抗体。

Objective To activate the patient s autoimmunity system in a prompt,convenient way.

The distribution of ABH substances in humantissue cells of nonsecretors differs from those insecretors.the contents of ABH in cells of nonsecretorswere much less than those of secretors.ABH substanceswere demonstred in cells of deep part of gastric gland,Brunner gland of duodenum,acini and duct of pancreas,acini and duct of sweat gland and in endothelial cells ofblood vessels and heart.

在国内外首次用免疫透射电镜对正常人体的胃、十二指肠、横结肠的粘膜上皮和腺上皮的ABH物质进行亚细胞定位研究后发现，ABH物质分布于粘膜上皮及粘液性细胞的Golgi器、粘原颗粒和胃腺主细胞的酶原颗粒中，证实人体组织细胞的ABH物质由自身产生，而不是从血液吸附。

OBJECTIVE: To separate the available composition that inhibits immunity form Ephedra sinica Stapf , and to study its effects on experimental autoimmune thyroiditis and its mechanism.

目的：从麻黄中分离出具有免疫抑制作用的有效部位，并研究其对小鼠实验性自身免疫性甲状腺炎的治疗作用及机理。

Glutamic acid decarboxylase is a major target antigen of humoral and cellular autoimmunity in type 1 diabetes mellitus. The autoantibodies against GADes protein is the most early and specific marker for type 1 diabetes mellitus, so it has been applied to the clinical practices widely.

谷氨酸脱羧酶是胰岛B细胞的一种主要自身抗原，与1型糖尿病细胞免疫和体液免疫有密切关系，已广泛应用于临床，作为糖尿病预测、诊断、分型、疗效监测的重要依据。

Department of Haemotology,Zhongda Hospital,Southeast University,Nanjing210009,China）Abstract:Cytokine induced killeris a new kind of immune cells which have non MHC restric-tion,highly proliferation and cytotoxicity.Their activities are superior to lymphokine activated killer cells.Immunotherapy of CIK cells can significantly improve clinical symptoms,but hardly have any side effects.

摘要］ 细胞因子诱导的杀伤细胞（cytokine induced killer，CIK）是一种非MHC限制性的新型免疫活性细胞，其增殖能力强、杀瘤活性高、副作用小，优于淋巴因子激活的杀伤细胞，对于提高患者自身抗肿瘤免疫能力有重要作用。

METHODS: After isolated the PBMCs and blood-plasma from adult human peripheral blood by Ficoll-Hypaque centrifugation, the PBMC culture procedure with or without the self-blood -plasma was applied to polarize T cells in vitro , these cells were polarized by PHA(20 mg/L),non-PHA respectively.

用Ficoll-Hypaque梯度离心法分离出正常成人抗凝外周血单个核细胞和血浆，将PBMC置于含或不含有自身血浆环境中，并在植物血凝素(PHA ，2 0mg L)的刺激下进行培养，培养 2 4、48、72h后收获细胞，分别用双色免疫荧光标记，以流式细胞术对CD4+ T细胞表达表面分子CCR3、CCR5进行分析。结果：CD4+ T细胞受自身血浆和PHA刺激后向Th1 Th2两个方向极化，2 4、48、72h后极化率分别达到(13 2 8± 1 5 9)%(12 70± 1 6 5 )%、(17 19± 1 0 3)%(17 5 0± 1 30 )%、(19 49± 2 87)%(18 5 8± 1 49)%；而只有PHA刺激的极化率很低，两组有显著性差异(P 0 1)；Th1∶Th2之比约等于 1。
