title: Murine splenocyte proliferation by porin of Shigella dysenteriae type 1 and inhibition of bacterial invasion of HeLa cell by anti-porin antibody.
abstract: The purified porin of Shigella dysenteriae type 1 showed strong mitogenic activity for murine splenocytes. Preincubation of S. dysenteriae type 1 with anti-porin antibody reduced the bacterial plaque formation in HeLa cell monolayers by 45%. The two immunobiological activities indicate that porin might be important in the induction of protective immunity against shigellosis.
