title: Lipopolysaccharide-reactive B cells against bromelain-treated mouse erythrocytes: preferential migration to and survival in the peritoneal cavity.
abstract: The ratio of lipopolysaccharide (LPS)-reactive B cells specific for bromelain-treated mouse erythrocytes (BrMRBC) to general LPS-reactive B cells is far higher in the peritoneal cavity of normal mice than in their spleen. To investigate the high concentration of anti-BrMRBC LPS-reactive B cells in the peritoneal cavity, spleen and peritoneal cells from (CBA/N X C3H/He)F1 female normal mice were injected intravenously and intraperitoneally into F1 male X-linked immunodeficient mice. Both groups of B cells in the intravenously transferred cell population were able equally to home in the spleen, but only anti-BrMRBC LPS-reactive B cells could be detected migrating into the peritoneal cavity. About half the anti-BrMRBC LPS-reactive B cells in the intraperitoneally transferred cell population could be recovered from the peritoneal cavity, but general LPS-reactive B cells were eliminated rather rapidly from the peritoneal cavity. Neither group of B cells could be detected migrating from the peritoneal cavity into the spleen. These findings suggest that the high concentration of anti-BrMRBC LPS-reactive B cells in the peritoneal cavity may be caused by their preferential ability to penetrate into the peritoneal cavity through circulation and survive there.
