VlsE, the variable surface antigen of Borrelia burgdorferi, contains a 26-amino-acid-long immunodominant invariable region, IR(6). In the present study, three overlapping 14-mer peptides reproducing the sequence of IR(6) were used as peptide-based enzyme-linked immunosorbent assay antigens to map this invariable region in infected monkeys, mice, and human Lyme disease patients. Antibodies of the two primate species appeared to recognize IR(6) as a single antigenic determinant, while mouse antibodies recognized multiple epitopes within this region.
伯氏疏螺旋体的可变表面抗原VlsE含有一个26个氨基酸长的免疫显性恒定区IR(6)。在本研究中,三种重叠的14肽再现了IR(6)的序列,用作基于肽的酶联免疫吸附测定抗原,以在受感染的猴子、小鼠和人类莱姆病患者中定位这个恒定区。两种灵长类动物的抗体似乎将IR(6)识别为单一抗原决定簇,而小鼠抗体识别该区域内的多个表位。
