    Notes: Abstract The participation of apoptotic cell death in the generalized Shwartzman reaction was examined. The generalized Shwartzman reaction was induced in mice by two consecutive injections of lipopolysaccharide. Vascular endothelial cells in various organs of those mice were stained positively by the in situ specific labeling of fragmented DNA. Renal tubules were also stained focally. It was suggested that apoptotic cell death might participate in the development of vascular endothelial cell damage and acute tubular necrosis in the generalized Shwartzman reaction. Simultaneous administration of anti-γ-interferon antibody in the preparative injection of lipopolysaccharide completely blocked apoptosis of vascular endothelial cells. Priming with recombinant γ-interferon instead of lipopolysaccharide could produce apoptosis of vascular endothelial cells. It was suggested that γ-interferon might play a critical role on sensitization of endothelial cells for apoptosis.

    Lipopolysaccharide induces apoptotic cell death of B memory cells and regulates B cell memory in antigen-nonspecific manner (1996)

    Notes: Abstract Lipopolysaccharide (LPS) was administered into sheep red blood cells (SRBC)-primed mice, and the effect of LPS on SRBC-specific memory cells was investigated. Spleen cells from SRBC-primed mice which were injected with LPS exhibited much lower in vitro secondary plaque-forming cells (PFC) responses to SRBC than those from untreated SRBC-primed mice. The in vitro anti-SRBC response of the spleen cells to LPS was also reduced. The combination experiments of B cells and T cells from SRBC-primed mice which were injected with or without LPS demonstrated that the reduction of immune responses to SRBC after administration of LPS was caused by the defect of SRBC-specific B memory cells, but not T memory cells. B cell type rosette-forming cells (RFC) for SRBC markedly decreased after injection of LPS, while PFC as antibody-forming cells did not increase subsequently. Therefore, the reduction of RFC was not due to their differentiation into PFC. The lymphoid follicles in the spleens from mice injected with LPS were stained positively by in situ nick end labeling specific for fragmented DNA. A large percentage of Ig+ spleen cells from SRBC-primed mice which were injected with LPS was also stained positively. The injection of glucocorticoids into SRBC-primed mice induced similar reduction of B memory cells. It was suggested that LPS might induce apoptosis of B memory cells and regulate B cell memory in antigen-nonspecific manner.

    Role of tumor necrosis factor-α and glucocorticoid on lipopolysaccharide (LPS)-induced apoptosis of thymocytes (1995)

    Notes: Abstract Administration of bacterial lipopolysaccharide (LPS) into mice markedly induced the apoptosis of CD4+8+ thymocytes. The injection of anti-tumor necrosis factor (TNF)-α antibody or RU38486, a glucocorticoid receptor antagonist, into mice definitely inhibited LPS-induced apoptosis of thymocytes. Addition of the sera 1 h after injection of LPS into in vitro cultures of thymocytes caused thymocyte apoptosis. It was also prevented by either anti-TNF-α antibody or RU38486. Further, recombinant TNF-α and hydrocortisone collaborated in induction of the thymocyte apoptosis in vitro. The in vivo phenomenon of LPS-induced apoptosis of thymocytes was reproducible by the in vitro experimental system. It was therefore suggested that both TNF-α and glucocorticoid participate and collaborate as effector molecules in LPS-induced apoptosis of thymocytes.

    Strong adjuvant action of Klebsiella O3 lipopolysaccharide and its inhibition of systemic anaphylaxis (1995)

    Notes: Abstract Immunization with lipopolysaccharide from Klebsiella O3 as an immunological adjuvant did not cause the death of mice in systemic anaphylaxis to bovine serum albumin. On the other hand, most mice immunized with lipopolysaccharide from Escherichia coli O111, Klebsiella O4 and Salmonella minnesota did die. Klebsiella O3 lipopolysaccharide enhanced IgM and IgG antibody response to BSA more markedly than Escherichia coli O111 lipopolysaccharide, while it affected the production of IgE antibody only slightly. Therefore, it is suggested that the inhibition of systemic anaphylaxis by Klebsiella O3 lipopolysaccharide adjuvant might be related to its strong adjuvant action on IgM and IgG class antibody production, and that high levels of circulating IgM and IgG antibodies might act as blocking antibodies in the development of IgE-mediated systemic anaphylaxis.
