Abstract

The binding of Borrelia burgdorferi OspE, OspF, and family 163 (Elp) proteins to factor H/factor H-like protein 1 (FHL-1) and other serum proteins from different animals was assessed. OspE paralogs bound factor H and unidentified serum proteins from a subset of animals, while OspF and Elp proteins did not. These data advance our understanding of factor H binding, the host range of the Lyme spirochetes, and the expanding role of OspE in pathogenesis.

摘要

评估了伯氏疏螺旋体OspE、OspF和163家族(Elp)蛋白与不同动物的补体因子H/补体因子H样蛋白1(FHL-1)及其他血清蛋白的结合情况。OspE旁系同源物可结合补体因子H及部分动物的未鉴定血清蛋白,而OspF和Elp蛋白则不能。这些数据增进了我们对补体因子H结合、莱姆螺旋体宿主范围以及OspE在发病机制中不断扩大的作用的理解。
