Like Thomas Hardy's famous novel Far from the Madding Crowd, parasites display their most relevant survival structures (proteins) involved in host cell invasion far away from the immune system's susceptible regions, displaying tremendous genetic variability, to attract the immune response and escape immune pressure. The 3D structure localisation of the conserved amino acid sequences of this deadly parasite's most relevant proteins involved in host cell invasion, as well as the location of the highly polymorphic, highly immunogenic regions, clearly demonstrates that such structures are far apart, sometimes 90° to 180° opposite, thereby rendering the immune response useless. It is also shown here that these conserved, functionally-relevant structures are immunologically silent, since no immune response has been induce.
就像托马斯·哈代的著名小说《远离尘嚣》一样,寄生虫在远离免疫系统易感性区域的地方展示其参与宿主细胞入侵的最相关生存结构(蛋白质),表现出巨大的遗传变异性,以吸引免疫反应并逃避免疫压力。这种致命寄生虫参与宿主细胞入侵的最相关蛋白质的保守氨基酸序列的三维结构定位,以及高度多态、高度免疫原性区域的位置,清楚地表明这些结构相距甚远,有时呈90°至180°相对,从而使免疫反应无效。这里还表明,这些保守的、功能相关的结构在免疫上是沉默的,因为没有诱导出免疫反应。
