Opis:
Cytotoxic activity is one of the major functions of Natural Killer (NK) cells and is a critical effector mechanism of innate immune responses against infected or cancer cells. A variety of assays have been developed to determine NK cell cytotoxic activity, however a receptor-based screening tool is still lacking. Here, we propose the CD25 receptor as a candidate for NK cell cytotoxicity marker. We have verified that there is a correlation between classic target cell induced cytotoxicity markers and the CD25 expression on NK cells. Non-adherent lymphocyte fractions pre-stimulated with Escherichia coli O55:B5 lipopolysaccharide were co-cultured with settled HeLa targets in a four hour long cytotoxic assay. The cytotoxic effect was evaluated by MTT reduction assay and quantification of soluble cytotoxicity markers (granzyme B, FasL, caspase-8, IFN-γ and IL-2) was done by ELISA. Lymphocytes were stained with anti-CD3-Cy-5, anti-CD56/CD16/Nkp46-FITC and anti-CD25-PE antibodies and analyzed by flow cytometry. We observed that the CD25 expression exclusively on the CD3-CD56+CD25+ NK cells was positively correlated with their cytotoxic function evaluated by the MTT test (r = 0.68), the upregulation of granzyme B (r = 0.89), IL-2 (r = 0.78) and IFN-γ (r = 0.57), however, it was not positively correlated with FasL and caspase-8. We conclude that the CD25 expression might serve as an in vitro receptor-based screening tool for NK cell activity.

Opis:
Interleukin 18 (IL-18) is a pleiotropic cytokine involved in the regulation of innate and acquired immune response. In the milieu of IL-12 or IL-15, IL-18 is a potent inducer of IFN-gamma in natural killer (NK) cells and CD4 T helper (Th) 1 lymphocytes. However, IL-18 also modulates Th2 and Th17 cell responses, as well as the activity of CD8 cytotoxic cells and neutrophils, in a host microenvironment-dependent manner. It is produced by various hematopoietic and nonhematopoietic cells, including dendritic cells and macrophages. In an organism, bioactivity of the cytokine depends on the intensity of IL-18 production, the level of its natural inhibitory protein - IL-18BP (IL-18 binding protein) and the surface expression of IL-18 receptors (IL-18R) on the responding cells. This review summarizes the biology of the IL-18/IL-18BP/IL-18R system and its role in the host defense against infections. The prospects for IL-18 application in immunotherapeutic or prophylactic interventions in infectious and non-infectious diseases are discussed.

Opis:
Helicobacter pylori (H. pylori) bacteria are human pathogens causing symptomatic gastritis, peptic ulcer or gastric cancer. Little is known about the kinetics of immune responses in H. pylori infected patients because the initial moment of infection has not been identified. Various animal models are used to investigate the immune processes related to H. pylori infection. In this study we checked whether H. pylori infection in guinea pigs, mimicking natural H. pylori infection in humans, resulted in the development of specific immune responses to H. pylori antigens by measuring the proliferation of lymphocytes localized in mesenteric lymph nodes, spleen and peripheral blood. The maturity of macrophages and cytokines, delivered by monocyte-macrophage lineage or lymphocytes, were considered as mediators, which might influence the lymphocyte blastogenic response. The obtained results showed the activation of T cells localized in mesenteric lymph nodes by H. pylori antigens in H. pylori infected guinea pigs four weeks postinfection. The blastogenic activity of lymphocytes was shaped by their interaction with antigen presenting cells, which were present in the cell cultures during the whole culture period. Moreover, the balance between cytokines derived from adherent leukocytes including interleukin 8 - IL-8 as well as interferon gamma - IFN-γ, and transforming growth factor beta - TGF-β delivered by lymphocytes, was probably important for the successful proliferation of lymphocytes. The H. pylori specific lymphocytes were not propagated in peripheral blood and spleen of H. pylori infected animals. The modulation of immunocompetent cells by H. pylori antigens or their different distribution cannot be excluded.

Opis:
Bacillus Calmette-Guérin (BCG) and pertussis vaccines have been found to be insufficient and their further improvement is required. In order to develop improved vaccines, a better understanding of the main pathways involved in the host's protective immunity to the pathogens is crucial. We address the question as to whether the balance between pro- and anti-inflammatory cytokine production might affect the host responses to BCG and diphtheria-tetanus toxoids-whole cell pertussis (DTwP) vaccines. The study population consisted of 118 healthy people, age range 18-30 years, who had been subjected to BCG and DTwP vaccination according to the state policy. Tuberculin skin testing (TST) revealed a delayed type hypersensitivity (DTH) to PPD (purified protein derivative) in 53% volunteers. The variability in development of the BCG-driven DTH to tuberculin prompted us to address a question as to whether Th1/Th2 polarization is involved in the lack of skin responsiveness to PPD. PPD-stimulated blood lymphocytes from TST+ participants produced significantly more IFN-γ and less IL-10 than lymphocytes from TST- volunteers. However, TST- volunteers' sera contained more anti-pertussis IgG but not anti-diphtheria toxin IgG. Mycobacterial antigens and particularly PPD induced a higher expression of HLA-DR and co-stimulatory CD80 receptors on DCs from TST+ than TST- participants. BCG but not PPD pulsed DCs from TST- volunteers produced significantly more IL-10. Mycobacterial antigen stimulated DCs from TST+ volunteers induced a more intense IFN-γ production in co-cultures with autologous lymphocytes than the cells from TST- participants. Differences among the types of dendritic cell activities contribute to development of tuberculin reactivity in BCG vaccinated volunteers.

Opis:
Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis (M.tb), remains a leading public health problem in most parts of the world. Despite the discovery of the bacilli over 100 years ago, there are still many unanswered questions about the host resistance to TB. Although one third of the world's population is infected with virulent M.tb, no more than 5-10% develop active disease within their lifetime. A lot of studies suggest that host genetic factors determine the outcome of M.tb-host interactions, however, specific genes and polymorphisms that govern the development of TB are not completely understood. Strong evidence exists for genes encoding pattern recognition receptors (TLR, CD14), C-type lectins, cytokines/chemokines and their receptors (IFN-γ, TNF-α, IL-12, IL-10, MCP-1, MMP-1), major histocompatibility complex (MHC) molecules, vitamin D receptor (VDR), and proton-coupled divalent metal ion transporters (SLC11A1). Polymorphisms in these genes have a diverse influence on the susceptibility to or protection against TB among particular families, ethnicities and races. In this paper, we review recent discoveries in genetic studies and correlate these findings with their influence on TB susceptibility.

Opis:
The role of Helicobacter pylori (H. pylori) antigens in driving a specific immune response against the bacteria causing gastroduodenal disorders is poorly understood. Using a guinea pig model mimicking the natural history of H. pylori infection, we evaluated the effectiveness of immature and mature macrophages in promoting the blastogenesis of splenocytes from H. pylori infected and uninfected animals, in response to H. pylori antigens: glycine acid extract (GE), cytotoxin associated gene A protein (CagA), urease A (UreA) and lipopolysaccharide (LPS). Lymphocyte expansion was assessed in 72 h cell cultures, containing: immature or mature macrophages derived from bone marrow monocytes, unstimulated or stimulated with H. pylori antigens for 2 h. The proliferation was expressed as a ratio of [3H]-thymidine incorporation into DNA of antigen-stimulated to unstimulated cells and the DNA damage was determined by DAPI cell staining. TGF-β and IFN-γ were assessed immunoenzymatically in cell culture supernatants. Lymphocytes of control and H. pylori-infected animals proliferated intensively in response to phytohaemagglutinin (PHA) and in co-cultures with immature or mature macrophages treated with CagA or UreA (significantly) and GE (slightly) exluding the cultures containing H. pylori or E. coli LPS. This lymphocyte growth inhibition was related to DNA damage of monocytic cells in response to H. pylori or E. coli LPS and secretion of regulatory TGF-β, but not proinflammatory IFN-γ. Impaired homeostasis of monocytic cell function related to DNA damage and TGF-β release, in response to H. pylori LPS may lead to the suppression of adaptive immune response against the bacteria and development of chronic infection.
