PMP2 and infection: 2006). Indeed, the present study shows that all nine members of the Pmp family encoded by serovar E of C. trachomatis, a urogenital pathogen, can mediate adhesion to epithelial and endothelial human cells in vitro, and that they are important for infection. Moreover, we provide evidence that recombinant Pmp2 from C. pneumoniae exhibits adhesive capacities to epithelial and endothelial cells, which is in agreement with other studies showing that specific anti-Pmp2 antibodies neutralize a C. pneumoniae infection (Finco et al. 2005).
