调节性B细胞的功能及其调控机制研究进展

open access: yes, 2016
B细胞在免疫系统中执行多重功能,包括递呈抗原,分泌抗体和各种细胞因子等。调节性B细胞( Regulatory B cells, Bregs)是新近发现的一类具有免疫抑制功能的B细胞亚群,参与维持机体免疫稳态,并且在各种免疫病理过程中如自身免疫疾病、肿瘤免疫反应、移植免疫耐受、感染及变态反应中发挥着重要调节作用。 Bregs既可以通过分泌细胞因子( IL-10、TGF-β和IL-35等)抑制免疫反应,也可以通过与靶细胞膜表面分子( FasL、GITRL和PD-L1等)的相互作用调节免疫应答 ...

エネルギー代謝を介したT細胞分化と長期免疫の誘導

open access: yes, 2021
T細胞は,抗原提示を受けた後に活性化および増殖し,その多くはエフェクターT細胞へと分化して様々な病原体や腫瘍細胞の排除に働くが,寿命が短く,その大半は短期間で死滅してしまう。一方,一部のT細胞は,メモリーT細胞へと分化して長期間体内で維持され,再び同じ抗原に出会うと,初回よりも強い免疫が誘導される。この現象は,ワクチン有効性の原理ともなっているが,このようなT細胞分化がどのように制御されているか不明な点も多く,現在の免疫学における重要な研究課題となっている。近年の研究から ...

铁死亡参与肝疾病研究进展

open access: yes浙江大学学报. 医学版
肝脏作为机体新陈代谢的核心器官,深度调节体内各类营养物质的合成及代谢。铁死亡作为一种铁依赖性的脂质过氧化物积累引起的新型细胞程序性死亡方式,参与多种急慢性肝疾病的生理和病理进程。目前认为,在急性肝损伤、代谢相关脂肪性肝病、酒精性肝病、病毒性肝炎、自身免疫性肝炎等大部分肝疾病中,铁死亡可加速疾病进程;而在晚期肝纤维化和肝细胞癌中,铁死亡则延缓疾病进程。因此,靶向调控铁死亡能够有效预防并延缓急慢性肝疾病的发生发展。本文讨论了铁死亡在急性肝损伤、代谢相关脂肪性肝病、酒精性肝病、病毒性肝炎、自身免疫性肝炎 ...

PD-1、PD-L1表达与食管癌的临床病理特征及预后的关系

open access: yesZhongguo shiyan zhenduanxue, 2018
研究发现程序性死亡因子-1(PD-1)、程序性死亡1-配体(PD-L1)在多种肿瘤细胞和肿瘤组织中均有表达,如黑色素瘤、非小细胞肺癌、肾母细胞瘤等,肿瘤组织中过度表达的PD-L1通过与PD-1结合下调抗肿瘤免疫反应[1,2]。目前已有多种免疫药物在临床上应用于多种恶性肿瘤,如pembrolizumab是一种高亲和力的结合PD-1的人源化IgG4-kappa抗体用于治疗晚期黑色素瘤,muvolumab用于治疗鳞状细胞肺癌,并取得美国食品药品管理局(FDA)通过及认证[3 ...

生物安全議定書下的事前告知同意程序與WTO之SPS協定中有關動植物進口程序的關係 ― 兼論台灣與議定書締約國訂定LMOs之跨境運輸協定 An Analysis on the relationship between sanitary and phytosanitary import procedures under the SPS Agreement of the WTO and the Advanced Informed Agreement procedures of the Biosafety Protocol [PDF]

open access: yesKējì Fǎxué Pínglùn, 2004
基因改造作物對於糧食安全以及生態環境的影響與衝擊目前係一尚無定論的議題。以生物多樣性資源的保育為出發點的「生物安全議定書」(以下簡稱議定書),希望透過事前告知同意程序的制度設計,替締約國在初次引進改性活生物體時,有一套可以依循的程序規範;在相同的國際管制帄台上,為預防外來種所造成對於一國環境生態的衝擊,WTO 也授權各國,依據「食品安全檢驗與動植物防疫檢疫措施協定」(SPS 協定)的規定,可以透過動植物檢疫措施的制訂以保護國內的生態系。兩套的進口管制制度是否相容,牽涉到國際環境公約與WTO ...
