Ultrastructural analysis of the pathogenesis of Neisseria gonorrhoeae endometrial infection

Abstract: SummaryWe have studied gonococcal infection in human endometrium organ culture and in human primary endometrial epithelial cells using various microscopic techniques including scanning electron microscopy, transmission electron microscopy, bright field light microscopy and laser scanning confocal microscopy. Here we describe the interactions between Neisseria gonorrhoeae and human endometrial luminal epithelial cells at the ultrastructural levels. N. gonorrhoeae attached to cilia but were not observed associat… Show more

“…Other bacteria such as Yersinia spp. and Neisseria gonorrhoeae induce plasma membrane ruffling to gain entry to host cells 75 , 76 . Additional bacterial effectors hijack cell signalling and the maturation of macropinosomes to avoid detection and destruction, creating protective vacuoles inside host cells for sequestration and proliferation.…”

“…Gonococcal pili and Opa co-operate during adherence to and invasion of HEC-1B cells [282]. This co-operative interaction was reported to co-localise with ASPG-R and CEACAM receptors on epithelial cells of the endometrium [283], suggesting that expression of these host cell receptors is possibly important for ascending infection. In addition, OmpA protein has been shown to mediate gonococcal adhesion to human cervical carcinoma and endometrial epithelial cells in vitro [139].…”

“…Although the ASGP-R is present within the female genital tract, it does not appear to mediate gonococcal infection of pex cells. However, the co-localization of gonococci with the ASGP-R on endometrial epithelium (Timmerman et al, 2005) could indicate that the ASGP-R plays a role in ascending infection in women. Challenge of ME-180 (omentum metastatic cervical epidermoid carcinoma) cells with a panel of LOS truncation mutants show adherence and invasion comparable to that of the wildtype strain (Minor et al, 2000).…”

“…The expression of CEACAMs on the mucosal surface of the female genital tract increases from the cervix to the fallopian tubes. Gonococci co-localize with CEACAMs on the luminal face of endometrial tissue (Timmerman et al, 2005). These data hint at a role for a CEACAM–gonococcus interaction in augment ascending infection in women; however, further studies to elucidate how ascending infection may progress in women are needed.…”
