Abstract

We have recently reported an increase of expression of the intercellular adhesion molecule 1 by renal carcinoma cells in response to S fimbriae of Escherichia coli. Now we demonstrate that E. coli expressing S and P fimbriae strongly binds to human proximal tubular epithelial cells. However, in primary and simian virus 40-transfected renal tubular epithelial cells S fimbriae do not enhance the expression of intercellular adhesion molecule 1.

摘要

我们最近报道,肾癌细胞对大肠杆菌S菌毛产生应答后,细胞间黏附分子1的表达增加。现在我们证明,表达S菌毛和P菌毛的大肠杆菌能强烈结合人近端肾小管上皮细胞。然而,在原代和经猿猴病毒40转染的肾小管上皮细胞中,S菌毛不会增强细胞间黏附分子1的表达。
