为了对抗一种致命脑癌,来自美国杜克大学的研究人员对一种通常会引起食物中毒的沙门氏菌进行了生物学改造,使其变成了一种可以杀伤肿瘤的“跟踪导弹”。

胶质母细胞瘤是最具侵袭性的一种脑癌,目前迫切需要治疗这种癌症的新方法。但是血脑屏障的存在使得对胶质母细胞瘤的药物治疗变得非常困难。手术完全移除肿瘤也存在很大难度即使留有很小的残余也会不可避免地长出新的肿瘤。

在这项研究中,研究人员对鼠伤寒沙门氏杆菌(Salmonella typhimurium)进行了一些基因改造使其变成了一种癌症追踪“导弹”,能够在肿瘤内部启动自毁命令。在动物模型上的检测结果表明存活时间超过100天的存活率达到20%(相当于人类寿命10年),并且肿瘤得到完全缓解。

相关研究结果发表在国际学术期刊Molecular Therapy-Oncolytics上。

之前一些研究曾发现细菌会引起免疫系统识别并攻击肿瘤。但是随后利用基因改造的去毒性沙门氏菌进行跟踪临床试验并未发现有抗肿瘤效果。该项目的研究人员选择了一株去毒性沙门氏菌,这株细菌同时缺少合成嘌呤的关键酶,迫使细菌寻找其他嘌呤供应。而肿瘤是嘌呤的最佳来源,这就会导致细菌向肿瘤靠拢。

研究人员还通过基因改造方法使细菌能够合成两种化合物——Azurin和p53,指引细胞进行自杀,但这种情况只有在低氧环境下发生。由于癌变细胞的快速扩增会消耗氧气,因此肿瘤周围及内部存在异常的低氧环境。

研究人员将改造后的细菌直接注射到实验动物脑部,这种治疗方法在大约20%的动物体内产生治疗效果,引起肿瘤的完全缓解,寿命也得到显著延长。

通过对未存活下来的实验动物进行分析,研究人员认为治疗没有起效的原因在于细菌进入肿瘤的能力存在不稳定性,或者肿瘤的生长速度超过了细菌。但是每只动物在接受治疗后都表现出改善症状。

研究人员表示,这是他们首次尝试设计这种治疗方法,还需要进行更多研究来进一步解决可能存在的问题。他们还计划对细菌进行改造合成不同药物引起肿瘤产生更强的反应。

一场秋雨一场寒,吃货们套上秋装,终于把减肥这回事抛到了脑后,纷纷盘算着要开始秋季进补啦。夏天不敢尽情享用的大鱼大肉此时都被招呼上了餐桌。不过人类有自己偏爱的食物,病菌们也是一样有自己热爱光顾的地盘。作为一名渊博的吃货,你知道你最钟爱的美食都是哪一类微生物热衷栖息的乐土吗?生鸡肉是沙门氏菌的乐土沙门氏菌是一种常见的食源性致病菌。1885年沙门氏等在霍乱流行时分离到猪霍乱沙门氏菌,因此将其定名为沙门氏

JFP:沙门氏菌可在夹心饼干中存活6个月以上!

乔治亚大学的研究者发现病原体如沙门氏菌可以在曲奇和饼干中存货至少6个月!佐治亚大学农业和环境科学学院杰出的名誉教授Larry Beuchat领导了一项研究,调查导致食源性疾病的细菌能在食物中存活多久。Beuchat说:“越来越多的食源性疾病与摄入受污染的干的食物有关。我们不期望沙门氏菌食物能够在非常干燥的环境中生长。”Beuchat和共同作者David Mann发现,有害细菌不存可以在干燥食物如曲

Am J Med:巨大感染性髂内动脉假性动脉瘤——案例报道

53岁男性反复发热、左腰痛进行性加重2个月,在这之前的几个月患者有盗汗、畏寒、疲劳、咽痛、体重下降10KG。既往史和家族史无特殊。查体:生命体征平稳,腹部无压痛。辅助检查:肌酸激酶升高(233 U/L),红细胞沉降率升高(64 mm/hr),C反应蛋白升高(62.3 mg/L)。血培养D族沙门氏菌阳性。CT血管造影提示靠近在左侧髂总动脉的分叉处有一个巨大的孤立的假动脉瘤,大小83 mm × 92

NEJM:一例沙门氏菌感染致假性动脉瘤案例报道

男性患者,66岁,既往有高血压病史,因发烧4天和声音嘶哑1天而入院就诊。据该患者称,他没有出现胸痛、咳嗽和呼吸困难等症状。

Nat Commun:从沙门氏菌获得灵感,攻克癌症耐药难题

在一项沙门氏菌试验中获得的惊人研究结果促成了一个研究发现,有可能使得传统化疗更容易治愈耐药癌细胞。麻省大学医学院的科学家们发现,沙门氏菌蛋白SipA可自然减少存在于许多不同类型癌细胞中的一种众所周知的耐药分子。通过传送附着这一蛋白的微型金纳米颗粒,研究人员可以大大提高肿瘤对一些化疗药物的敏感性,并缩小了小鼠体内的结肠癌和乳腺癌肿瘤。这项研究发布在7月25日的《自然通讯》(Nature Commun
