摘要
Abstract
In order to understand the role of transmembrane signal transduction of host cells in the early steps of infection
the adherence of E. coli to HEp 2 cells and the change of activity of phospholipase C γ (PLC γ) induced by the adherence were investigated.The adherence of enteropathogenic E.coli (EPEC)
strain E.7
induced a significant increase of inositol triphosphat (IP 3) level in HEp 2 cells. The adherence of the bacteria and the increase of IP 3 was kinetically correlated. Whereas the increase of IP 3 level induced by the adherence of the control strain EPEC (H511)
a non piliated strain
was much meager than that by E7
a piliated strain. The results highlighted an important role of transmembrane signals like IP 3 in the pathogenesis of EPEC.
