Cancer immunotherapy with blocking of immune checkpoints [PDF]

open access: yes, 2013
がんワクチンによる免疫治療では,如何にCD8T細胞を感作(プライミング)しその数を増やすか(免疫増強)という点に多大の努力が払われて来た.樹状細胞への抗原デリバリーと抗原プロセシング/提示,Toll様受容体などの刺激,即ち自然免疫系の活性化の併用などはそれに該当する.しかし十分に活性化されたT細胞をもってしても癌の拒絶は容易ではない.それには癌組織という特殊な環境が禍している.T細胞は癌塊内に入り込み莫大な数の癌細胞と遭遇する.癌組織内での繰り返す抗原認識の過程でT細胞は疲弊し ...

The transcriptional coactivator TAZ regulates reciprocal differentiation of T(h)17 cells and T(reg) cells [PDF]

open access: yes, 2017
自身免疫性疾病是一类机体对自身抗原发生免疫反应而导致自身多器官、组织受累的慢性炎症性疾病。目前大量研究表明机体内促炎症的TH17细胞和抑制炎症Treg细胞在类群数量和活化状态的失衡是造成自身免疫疾病的主要致病因素。陈兰芬教授和周大旺教授团队的前期研究发现小鼠中Hippo信号通路中激酶Mst1/2缺失导致免疫缺陷,机体易受病原体感染并伴随着严重自身免疫疾病。该研究揭示了Hippo 信号通路转录共激活因子TAZ在决定CD4 ...

Applying TALEN and CRISPR/Cas9 Technique to Knock out the PD1 Gene in Human Primary T Lymphocytes [PDF]

open access: yes, 2016
过继性细胞免疫治疗(adoptivecellularimmunotherapy)是将患者自体免疫细胞在体外处理,然后筛选并大量扩增具有高度特异性的肿瘤杀伤性免疫效应细胞,再回输到患者体内杀灭肿瘤的一种治疗方法,过继性T细胞治疗是一种很有前景的癌症治疗方法。体内T细胞在进行免疫应答时,T细胞活化需要双重信号的协同作用,分别是抗原呈递信号和协同刺激信号。协同刺激分子通过为淋巴细胞提供正性或负性的调控信号参与机体的免疫调控。肿瘤细胞会利用体内免疫调节过程,表达或分泌的一些分子,对T细胞进行负向调控 ...

The role of Rip3-mediated necrosis in system inflammatory response syndrome [PDF]

open access: yes, 2016
肿瘤坏死因子-α可以诱导小鼠发生全身免疫反应综合征,其过程中发生了各组织器官的坏死和一系列级联免疫反应。在肿瘤坏死因子-α的作用下,组织细胞中的受体相互作用蛋白3被激活并募集坏死小体,导致细胞坏死,引起周围组织的炎症反应。同时,肿瘤坏死因子-α本身作为促炎因子扩大了机体免疫反应的范围。在肿瘤坏死因子-α诱导的全身免疫反应综合征中,盲肠首先表现出损伤,并且这种损伤可以被Rip3基因敲除所抑制。本论文通过建立小鼠盲肠切除术模型,与肿瘤坏死因子-α诱导全身免疫反应综合征模型并用 ...

Deep Learning–Driven Surface‐Enhanced Raman Scattering–Lateral Flow Immunoassay With Au Nanostars for High‐Accuracy Respiratory Virus Detection

open access: yesRare Metals, EarlyView.
ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Hybrid Probiotic Hydrogel With Curcumin‐Loaded MnO2 Nanoparticles Enhances Diabetic Wound Healing Through Multimodal Microenvironmental Regulation

open access: yesRare Metals, EarlyView.
ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

Fibronectin binds to C1q : possible mechanisms for their co-precipitation in cryoglobulins from patients with systemic lupus erythematosus [PDF]

open access: yes, 1984
近年、全身性エリテマトーデス (SLE)患者の血清中に認められるクリオグロブリン中にフィブロネクチンの存在が証明されている。クリオグロブリンについては、発生機序をはじめ不明な点が多いが、免疫グロブリンと補体を含むことから免疫複合体と考えられており、その検出は SLEなどの免疫複合体病の診療において簡便な免疫複合体の証明法として用いられている。このような背景から、フィブロネクチンの活性を検討することを目的とし、「フィブロネクチンは C1qのコラーゲン類似部分によって C1qに結合し ...
