结核分枝杆菌和牛分枝杆菌有99%的遗传相似性,并在感染后引起相似的宿主反应和疾病概况。在开发适用于人和牛结核病(TB)的控制措施方面,有丰富的共同发现历史,包括皮肤测试程序、牛分支杆菌卡介苗接种和干扰素-γ释放试验。小牛结核病感染模型为我们进一步了解结核病的免疫发病机制提供了几个机会。最近的观察包括:中枢记忆免疫反应与结核病疫苗效力的相关性,ESAT-6中Sirpα+细胞的关联:CFP10诱导的多核巨细胞形成,γδT细胞对TB的早期反应,记忆CD4+T细胞通过产生颗粒溶素而产生的抗分枝杆菌活性,特异性抗体与抗原负荷的关联,以及受感染动物的先天免疫基因表达的抑制。具有兽医和医学观点的研究人员组成的合作伙伴关系将继续为人类和动物的结核病研究提供互惠互利。
Mycobacterium tuberculosis and M. bovis share >99% genetic identity and induce similar host responses and disease profiles upon infection. There is a rich history of codiscovery in the development of control measures applicable to both human and bovine tuberculosis (TB) including skin-testing procedures, M. bovis BCG vaccination, and interferon-γ release assays. The calf TB infection model offers several opportunities to further our understanding of TB immunopathogenesis. Recent observations include correlation of central memory immune responses with TB vaccine efficacy, association of SIRPα + cells in ESAT-6:CFP10-elicited multinucleate giant cell formation, early γδ T cell responses to TB, antimycobacterial activity of memory CD4+ T cells via granulysin production, association of specific antibody with antigen burden, and suppression of innate immune gene expression in infected animals. Partnerships teaming researchers with veterinary and medical perspectives will continue to provide mutual benefit to TB research in man and animals.
