Cytokine profiles were examined 1 month after primary vaccination of infants with a whole-cell pertussis vaccine (wP) (Connaught) or either of two acellular pertussis vaccines, aP-Chiron Biocine (aP-CB) or aP-SmithKline Beecham (aP-SB), each combined with diphtheria-tetanus toxoids (DT), in Bordetella pertussis antigen-stimulated or unstimulated peripheral blood mononuclear cells (PBMC). Pertus...
Ag-stimulated IL-2 production and mitogen-stimulated type 1 and type 2 cytokine production by PBMC, as well as expression of Th1- and Th2-associated phenotypical markers, of B7-1, B7-2, and CD95 (Fas) on the surface of immune cells, and the serum concentration of soluble Apo-1/Fas were evaluated in multiple sclerosis (MS) patients with either acute (AMS) or stable (SMS) disease and in healthy c...
BACKGROUND Circulatory failure in sepsis arises from vascular hyporesponsiveness, in which nitric oxide (NO) derived from inducible NO synthase (iNOS) plays a major role. Details of the cross talk between thromboxane (TX) A2 and the iNOS-NO system, however, remain unknown. We intended to clarify the role of TXA2, via the cross talk, in vascular hyporesponsiveness. METHODS AND RESULTS We exami...
Early interactions of innate immune cell populations, such as dendritic cells (DC) and natural killer (NK) cells, can affect the ability of the acquired immune response to control infection of intracellular microorganisms. In this study, we investigated the activation of bovine NK cells by CD13(+) splenic DC stimulated with either Mycobacterium bovis BCG or Babesia bovis merozoites. Splenic DC ...
Lignin-like polymerized polyphenols strongly activate lymphocytes and induce cytokine synthesis. We aimed to characterise the mechanisms of action of polymerized polyphenols on immunomodulating functions. We compared the reactivity of leukocytes from various organs to that of polymerized polyphenols. Splenocytes and resident peritoneal cavity cells (PCCs) responded to polymerized polyphenols an...
The ability of extracellular stimuli to modulate dendritic cell (DC) activation of natural killer T (NKT) cells was not well understood. We investigated the effects of the T helper type 1 (Th1)/Th2-cytokine environment on DC induction of NKT cell-mediated cytokine production in mice. Pretreatment of myeloid DCs with Th1 or Th2 cytokines, interleukin (IL)-4 or interferon (IFN)-gamma, led to the ...
The granulomatous response to schistosome eggs is a CD4 T-cell-dependent, Th2-cytokine-dominated immunopathologic response. As infection proceeds to chronicity, both granuloma formation and egg-induced cytokine production become downregulated, and previous experiments have implicated CD8 T cells in this process. One mechanism by which CD8 T cells could suppress immunopathology is through the pr...
Shiga toxin (Stx)-producing Escherichia coli (STEC) is associated with hemolytic uremic syndrome (HUS). High inflammatory cytokine [interleukin (IL)-6 and IL-8] levels and low anti-inflammatory cytokine (IL-10) levels are indicators of a high risk for developing HUS in STEC-infected children. In this study, we investigated inhibitory action of telithromycin, a ketolide, against STEC and against...
Infection causes 0.6 million of the total 2.9 million neonatal deaths every year and devastates the lives of millions more who initially survive; it mercilessly seeks out those weakened by premature delivery and/or low birth weight (LBW), an unfortunate combination too frequently encountered all over the world but particularly so in low-income countries [1]. Reduction of neonatal mortality over...
Hepatitis B virus (HBV) infection, a cause of hepatocellular carcinoma (HCC), remains a serious global health concern. HCC development and human hepatocarcinogenesis are associated with hepatic inflammation caused by host interferons and cytokines. This article focused on the association between the HBV core protein, which is one of the HBV-encoding proteins, and cytokine production. The HBV co...
