Objective To investigate the association between β3 integrin-fibronectin signaling and salpingitis. Methods Thirteen chronically inflamed tubal samples were included in the case group, while 29 normal fallopian tube samples were set as the controls. Immunohistochemistry was used to determine the distribution patterns and expressions of β3 integrin and fibronectin in the fallopian tube samples. Results β3 integrin was presented in the ciliated cells within the whole length of the normal fallopian tube, but no staining was detected in the tubal epithelium of salpingitis. A similar distribution pattern of fibronectin was revealed between the cases and the controls, with exclusive staining in the tubal mucosal matrix and the basement membranes of the tubal epithelium and mucosal vessels, whereas no staining was detected in the tubal epithelial cells. Fibronectin in the samples of salpingitis showed a remarkably stronger-staining than that of the normal controls (P<0.01). Conclusion Salpingitis could reduce β3 integrin expression and raise fibronectin expression in the fallopian tube epithelium, concomitantly changed concentrations of β3 integrin and fibronectin seem to have impacts on the onset of salpingitis.
