We studied the effect of antibodies against Porphyromonas gingivalis gingipain domains, preparing them against three recombinant fragments of RgpA (catalytic domain, r-Rgp CAT; hemagglutinin domains, r-Rgp 44 and r-Rgps 15-27) and one fragment of Kgp (catalytic domain, r-Kgp CAT). Enhancement of opsonization and killing by human polymorphonuclear leukocytes were measured in the noninvasive FDC 381 and invasive W50 strains of P. gingivalis. Anti-r-Rgp 44 was the most effective in both strains of P. gingivalis. The present findings lead us to recommend RgpA 44 as a candidate immunogen for vaccines against P. gingivalis.
我们研究了抗牙龈卟啉单胞菌牙龈蛋白酶结构域抗体的作用,制备了针对RgpA的三个重组片段(催化结构域,r-Rgp CAT;血凝素结构域,r-Rgp 44和r-Rgps 15-27)以及Kgp的一个片段(催化结构域,r-Kgp CAT)的抗体。在牙龈卟啉单胞菌的非侵袭性FDC 381菌株和侵袭性W50菌株中,检测了人多形核白细胞调理吞噬作用和杀伤作用的增强情况。抗r-Rgp 44在牙龈卟啉单胞菌的两种菌株中最为有效。目前的研究结果使我们推荐RgpA 44作为抗牙龈卟啉单胞菌疫苗的候选免疫原。
