Campylobacter jejuni is a leading cause of bacterial gastroenteritis linked to several serious autoimmune sequelae such as the peripheral neuropathies Guillain Barré syndrome (GBS) and Miller Fisher syndrome (MFS). We hypothesized that GBS and MFS can result in NOD wild type (WT) mice or their congenic interleukin (IL)-10 or B7-2 knockouts secondary to C. jejuni infection. Mice were gavaged orally with C. jejuni strains HB93-13 and 260.94 from patients with GBS or CF93-6 from a patient with MFS and assessed for clinical neurological signs and phenotypes, anti-ganglioside antibodies, and cellular infiltrates and lesions in gut and peripheral nerve tissues. Significant increases in autoantibodies against single gangliosides (GM1, GQ1b, GD1a) occurred in infected NOD mice of all genotypes, although the isotypes varied (NOD WT had IgG1, IgG3; NOD B7-2-/- had IgG3; NOD IL-10-/- had IgG1, IgG3, IgG2a). Infected NOD WT and NOD IL-10-/- mice also produced anti-ganglioside antibodies of the IgG1 isotype directed against a mixture of GM1/GQ1b gangliosides. Phenotypic tests showed significant differences between treatment groups of all mouse genotypes. Peripheral nerve lesions with macrophage infiltrates were significantly increased in infected mice of NOD WT and IL-10-/- genotypes compared to sham-inoculated controls, while lesions with T cell infiltrates were significantly increased in infected mice of the NOD B7-2-/- genotype compared to sham-inoculated controls. In both infected and sham inoculated NOD IL-10-/- mice, antibiotic treatment exacerbated neurological signs, lesions and the amount and number of different isotypes of antiganglioside autoantibodies produced. Thus, inducible mouse models of post-C. jejuni GBS are feasible and can be characterized based on evaluation of three factors-onset of GBS clinical signs/phenotypes, anti-ganglioside autoantibodies and nerve lesions. Based on these factors we characterized 1) NOD B-7-/- mice as an acute inflammatory demyelinating polyneuropathy (AIDP)-like model, 2) NOD IL-10-/- mice as an acute motor axonal neuropathy (AMAN)-like model best employed over a limited time frame, and 3) NOD WT mice as an AMAN model with mild clinical signs and lesions. Taken together these data demonstrate that C. jejuni strain genotype, host genotype and antibiotic treatment affect GBS disease outcomes in mice and that many disease phenotypes are possible.

空肠弯曲杆菌感染后在非肥胖糖尿病(NOD)小鼠中诱发格林格林Barré综合征,并被抗生素加重。

空肠弯曲菌是细菌性肠胃炎的主要原因,它与几种严重的自身免疫性后遗症有关,例如外周神经病GuillainBarré综合征(GBS)和Miller Fisher综合征(MFS)。我们假设GBS和MFS可以导致NOD野生型(WT)小鼠或其继发于空肠弯曲杆菌感染的同基因白介素(IL)-10或B7-2敲除。小鼠接受空肠弯曲杆菌HB93-13和260.94的GBS或CF93-6的MFS病人的口服灌胃,并评估其临床神经系统症状和表现型,抗神经节苷脂抗体以及细胞浸润和肠道及周围组织的病变神经组织。尽管同种型各异(NOD WT含有IgG1,IgG3;同种型不同),但感染了所有基因型的NOD小鼠中都出现了针对单个神经节苷脂(GM1,GQ1b,GD1a)的自身抗体的显着增加。NOD B7-2-/-具有IgG3;NOD IL-10-/-具有IgG1,IgG3,IgG2a)。感染的NOD WT和NOD IL-10-/-小鼠也产生了针对GM1 / GQ1b神经节苷脂混合物的IgG1同型抗神经节苷脂抗体。表型测试显示所有小鼠基因型的治疗组之间存在显着差异。与假接种的对照组相比,NOD WT和IL-10-/-基因型感染小鼠的巨噬细胞浸润周围神经病变明显增加,而NOD B7-2-//感染小鼠的T细胞浸润病变明显增加。 -与假接种对照相比的基因型。在感染和假接种的NOD IL-10-/-小鼠中,抗生素治疗都会加剧神经系统症状,损害以及产生的抗神经节苷脂自身抗体的不同同种型的数量和数量。从而,C后的诱导型小鼠模型。空肠GBS是可行的,并且可以基于对GBS临床体征/表型,抗神经节苷脂自身抗体和神经病变的三个因素的评估来表征。基于这些因素,我们表征为1)NOD B-7-/-小鼠为急性炎症性脱髓鞘性多发性神经病(AIDP)样模型,2)NOD IL-10-/-小鼠为急性运动性轴突神经病(AMAN)样该模型最适合在有限的时间范围内使用; 3)NOD WT小鼠是具有轻度临床体征和病变的AMAN模型。这些数据加在一起表明空肠弯曲杆菌菌株基因型,宿主基因型和抗生素治疗会影响小鼠的GBS疾病结局,并且许多疾病表型都是可能的。空肠GBS是可行的,并且可以基于对GBS临床体征/表型,抗神经节苷脂自身抗体和神经病变的三个因素的评估来表征。基于这些因素,我们表征为1)NOD B-7-/-小鼠为急性炎症性脱髓鞘性多发性神经病(AIDP)样模型,2)NOD IL-10-/-小鼠为急性运动性轴突神经病(AMAN)样该模型最适合在有限的时间范围内使用; 3)NOD WT小鼠是具有轻度临床体征和病变的AMAN模型。这些数据加在一起表明,空肠弯曲杆菌菌株的基因型,宿主基因型和抗生素治疗会影响小鼠的GBS疾病结局,而且许多疾病表型都是可能的。空肠GBS是可行的,并且可以基于对GBS临床体征/表型,抗神经节苷脂自身抗体和神经病变的三个因素的评估来表征。基于这些因素,我们表征为1)NOD B-7-/-小鼠为急性炎症性脱髓鞘性多发性神经病(AIDP)样模型,2)NOD IL-10-/-小鼠为急性运动性轴突神经病(AMAN)样该模型最适合在有限的时间范围内使用; 3)NOD WT小鼠是具有轻度临床体征和病变的AMAN模型。这些数据加在一起表明,空肠弯曲杆菌菌株的基因型,宿主基因型和抗生素治疗会影响小鼠的GBS疾病结局,而且许多疾病表型都是可能的。基于这些因素,我们表征为1)NOD B-7-/-小鼠为急性炎症性脱髓鞘性多发性神经病(AIDP)样模型,2)NOD IL-10-/-小鼠为急性运动性轴突神经病(AMAN)样该模型最适合在有限的时间范围内使用; 3)NOD WT小鼠是具有轻度临床体征和病变的AMAN模型。这些数据加在一起表明空肠弯曲杆菌菌株基因型,宿主基因型和抗生素治疗会影响小鼠的GBS疾病结局,并且许多疾病表型都是可能的。基于这些因素,我们表征为1)NOD B-7-/-小鼠为急性炎症性脱髓鞘性多发性神经病(AIDP)样模型,2)NOD IL-10-/-小鼠为急性运动性轴突神经病(AMAN)样该模型最适合在有限的时间范围内使用; 3)NOD WT小鼠是具有轻度临床体征和病变的AMAN模型。这些数据加在一起表明,空肠弯曲杆菌菌株的基因型,宿主基因型和抗生素治疗会影响小鼠的GBS疾病结局,而且许多疾病表型都是可能的。
