利用一系列缺失构建体和重组多肽,通过Western印迹和酶联免疫吸附试验,确定了一组抗变形链球菌表面蛋白P1的单抗识别表位的序列。识别由富含丙氨酸和富脯氨酸的重复结构域和不同程度的侧翼序列组合而成的复杂不连续表位的单抗以及结合包含在P1连续片段内的表位的单抗被鉴定出来。与戈登链球菌SSPA和SspB的交叉反应也有报道。这些信息使我们能够深入了解链球菌粘附素的结构和功能及其保护作用的相关性,并进一步了解抗P1单抗的免疫调节和细菌黏附抑制活性。
Sequences contributing to epitopes recognized by a panel of monoclonal antibodies (mAbs) against theStreptococcus mutanssurface protein P1 were delineated by Western blot and enzyme-linked immunosorbent assay using a battery of deletion constructs and recombinant polypeptides. mAbs that recognize complex discontinuous epitopes reconstituted by combining the alanine-rich and proline-rich repeat domains and varying degrees of flanking sequence were identified as well as mAbs that bound epitopes contained within contiguous segments of P1. Cross-reactivity with SspA and SspB fromStreptococcus gordoniiis also reported. This information enables insight into the structure and function of a streptococcal adhesin and its correlates of protection and furthers our understanding of the immunomodulatory and bacterial-adherence inhibition activities of anti-P1 mAbs.
