J Invest Dermatol:CD4+T细胞的增殖和补体系统的参与泛发性脓疱型银屑病MPO的缺陷

广泛性脓疱型银屑病(GPP)属于较为罕见的脓疱亚型。 未来评估受影响的细胞类型和途径的研究将显示它们在GPP发病机制中的作用,并表明研究结果是否可以转移到急性表皮情况。

     银屑病是一种常见的自身免疫性疾病,在发达国家约有2-3%的人口受其影响,而广泛性脓疱型银屑病(GPP)属于较为罕见的脓疱亚型。GPP是一种多系统疾病,通常发生在急性,潜在的威胁生命的事件,需要住院治疗。组织学上,中性粒细胞为主的无菌表皮脓疱是GPP的特征。编码白介素-36受体拮抗剂(IL-36Ra,基因IL36RN)的基因变异已被确定为致病基因。IL-36受体(IL-36R)及其配体前体IL-36α、-β和-γ主要在角质形成细胞中表达,而IL-36R在骨髓源性细胞中的表达已进行过描述:小鼠和人的树突状细胞以及人的中性粒细胞。

      IL-36信号转导导致核因子-κB和丝裂原活化蛋白激酶的激活,导致促炎细胞因子的产生,如IL-8。在IL36RN变异的患者中,IL-36途径有利于角质形成细胞中促炎细胞因子的产生。针对IL-36R的治疗在有和没有IL36RN变异的患者中显示了良好的反应,突出了这一途径在GPP中的中心作用。

     尽管IL36RN和MPO的变异可以影响免疫细胞,但目前还没有对中性粒细胞和外周血单个核细胞(PBMC)亚群以及它们的差异基因表达与MPO基因型的关系进行系统的分析。

     我们使用PBMCs的单细胞RNA测序(ScRNAseq)和稳定期中性粒细胞的RNA测序来评估MPO缺陷患者的转录组。

     细胞表面和细胞内标志物的流式细胞术分析验证了scRNAseq数据多模式参考图对细胞类型的标注:GPP中CD4+细胞毒性T淋巴细胞(CTL)和其他CD4+效应细胞比例增加,而单纯CD4+T细胞比例明显降低。标志CD4+CTL和CD8+效应记忆T细胞(TEMs)的FGFFBP2在具有致病变异的GPP患者中的表达高于非携带者(p=0.0015)。在中性粒细胞中,差异表达基因(Deg)明显富含经典补体激活途径的基因。

      未来评估受影响的细胞类型和途径的研究将显示它们在GPP发病机制中的作用,并表明研究结果是否可以转移到急性表皮情况,以及CD4+CTL是否耗尽或失活可能是合理的治疗方法。

J Clin Pathol:游离轻链!HIV感染监测新目标

还在关注HIV感染者CD4+T细胞的数量吗?是时候把视线转移到游离轻链的变化上了!血清游离轻链可以分为κ和λ两类。现在已经出现自动化试验,可以用来检测血清游离轻链的浓度,并常规用来对多发性骨髓瘤患者或由单克隆球蛋白增多症引起的其他功能紊乱进行诊断和随访。异常的κ/λ比例与多发性骨髓瘤、浆细胞瘤等疾病的进展风险有关。另外,在其他B细胞恶性疾病如慢性淋巴细胞白血病和非霍奇金淋巴瘤中也能发现异常的κ/λ

Science:衰老造成CD4+T细胞免疫力下降和基因表达不稳定

年轻的CD4+T细胞在受到刺激后,就算来自不同种族的CD4+T细胞,也统一的表达调节免疫的关键基因群。相反,年老的CD4+T细胞在受到刺激后,节免疫的关键基因群的表达程度下降,但是细胞和细胞间的基因表达的一致性下降,造成了更多的个体差异。这项研究,为衰老引起的免疫力低下,以及基因表达的不稳定和突变几率的上升提供了理论支持。
