    发作性睡病1型患者夜间REM睡眠起始标记的重测稳定性不佳

    一项发表于SLEEP的观察性研究纳入227例未治疗的发作性睡病1型(NT1)儿童和成人,每位患者接受两次夜间多导睡眠图检查。结果显示nSOREMP在两次检查均出现者仅占41.8%,重测一致性差(κ=0.26,95% CI 0.14-0.39);nDREM同样稳定性差。研究者认为其与年龄、MSLT结果和下丘脑分泌素水平相关提示REM调节的变异性,并提出两次PSG均未见nSOREMP也不应排除NT1。

    VRC01抗体预防HIV-1感染随访至104周:敏感毒株获保护后出现耐药突破感染

    研究团队分析AMP两项平行试验至104周最终访视的HIV-1获得情况:静脉输注广谱中和抗体VRC01后,对VRC01高度敏感(IC80<阈限)的病毒感染被阻断,而随着体内VRC01浓度下降,在药物选择压力下 evolved 出更强耐药性的病毒以可检出的突破感染出现(VRC01组11例对安慰剂组1例)。结果提示单株抗体只能阻断敏感株,预防病毒逃逸与突破感染可能需要多种抗体联合。

    EMBO Journal研究:四跨膜蛋白CD81抑制埃博拉病毒感染,病毒糖蛋白GP和基质蛋白VP40可拮抗CD81

    埃博拉病毒糖蛋白GP降低细胞表面四跨膜蛋白CD81、CD63和CD9的可用性,该功能在多种丝状病毒糖蛋白中保守。研究显示CD81抑制病毒样颗粒进入和病毒复制,可能通过抑制VP40诱导的NF-κB信号起效,且GP与VP40均与CD81相互作用并降低其表达;CD81抗体聚集可抑制感染。研究提示CD81是潜在可成药的埃博拉病毒抑制性宿主因子(The EMBO Journal)。
