Abstract
BACKGROUND Anisakis simplex antigens present immunomodulatory properties by the induction of tolerogenic dendritic cells (DCs) in mice. OBJECTIVES To study the capacity of DCs stimulated with A. simplex excretory-secretory (ES) or crude extract (CE) to generate Tregs. To investigate in vitro effects of antigens on the metabolic activity of splenocytes induced by LPS or CpG. METHODS Phenotypic and functional characterization of T cells co-cultured with A. simplex-pulsed DCs was performed by flow cytometry. Lymphocyte mitochondrial respiratory activity was estimated by the Alamar Blue® Assay. FINDINGS In C57BL/6J, CD4+CD25-Foxp3+ and CD8+CD25-Foxp3+ populations increased by CE-stimulated-DCs. In BALB/c, CE-stimulated-DCs caused the expansion of CD4+CD25+Foxp3+IL-10+ and CD8+CD25+Foxp3+IL-10+. IFN-γ expression raised in BALB/c CD4+CD25+ and CD4+CD25- for CE and ES, respectively. ES-stimulated-DCs increased CD4+CD25+ Foxp3+ and CD8+CD25- Foxp3+ expression in T cells. The association of ES or CE with LPS produced the increase in splenocyte activity in C57BL/6J. The association of CE with CpG decreased the proliferation caused by CpG in C57BL/6J. MAIN CONCLUSIONS A. simplex increase the frequency of Tregs, which in turn produce IL-10 and IFN-γ. The host genetic base is essential in the development of anti-Anisakis immune responses (Th2, Th1, Treg).

DC-SIGN signalling induced by Trichinella spiralis products contributes to the tolerogenic signatures of human dendritic cells. Sci Rep 2020; 10:20283. [PMID: 33219293 PMCID: PMC7679451 DOI: 10.1038/s41598-020-77497-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Accepted: 11/11/2020] [Indexed: 12/28/2022] Open
Abstract
Tolerogenic dendritic cells (tolDCs) are central players in the maintenance of immune tolerance and thereby have been identified as the most favourable candidates for cell therapy of autoimmune diseases. We have recently shown that excretory-secretory products (ES L1) released by Trichinella spiralis larvae induce stable human tolDCs in vitro via Toll-like receptor 2 (TLR2) and TLR4. However, engagement of these receptors did not fully explain the tolerogenic profile of DCs. Here, we observed for the first time that dendritic cell-specific ICAM-3 grabbing non-integrin (DC-SIGN) interacts with highly glycosylated ES L1 and contributes to the generation of ES L1-induced tolDCs. Blocking DC-SIGN interfered with the ES L1-induced higher expression of CD40 and CCR7 and the production of IL-10 and TGF-β by DCs. The cooperation of TLR2, TLR4 and DC-SIGN receptors is of importance for the capacity of DCs to prime T cell response toward Th2 and to induce expansion of CD4+CD25+Foxp3+ T cells, as well as for the production of IL-10 and TGF-β by these cells. Overall, these results indicate that induction of tolDCs by ES L1 involves engagement of multiple pattern recognition receptors namely, TLR2, TLR4 and DC-SIGN.

Abstract
Malignant gliomas are the most common brain tumors with high rates of recurrence
and mortality. Novel approaches are in research, and immunotherapy emerges as a
promising strategy. Recently, scientific attention has been focused on
Ganoderma lucidum polysaccharides (GL-PS), one of the
critical bioactive components of G lucidum, which have been
recognized as a promising natural source of immunomodulatory and anticancer
compounds. It remains unknown whether the GL-PS have any immunomodulatory and
anticancer effects on brain glioma. This study was designed to identify and
characterize the antitumor action and influence of immune system of GL-PS in
glioma-bearing rats. Results showed that GL-PS increased the concentration of
serum interleukin-2, tumor necrosis factor-α, and interferon-γ, and enhanced the
cytotoxic activity of natural killer cells and T cells, promoting the functional
maturation of dendritic cells, thus resulting in the inhibition of glioma growth
and prolonged survival of rats. Therefore, GL-PS may be potentially useful as
part of the treatment regimen to regulate host immune responses and increase the
antitumor effects of immunotherapy for glioma.

Abstract
Trichinella spiralis has the unique ability to make itself "at home" by creating and hiding in a new type of cell in the host body that is the nurse cell. From this immunologically privileged place, the parasite orchestrates a long-lasting molecular cross talk with the host through muscle larvae excretory-secretory products (ES L1). Those products can successfully modulate parasite-specific immune responses as well as responses to unrelated antigens (either self or nonself in origin), providing an anti-inflammatory milieu and maintaining homeostasis. It is clear, based on the findings from animal model studies, that T. spiralis and its products induce an immunomodulatory network (which encompasses Th2- and Treg-type responses) that may allow the host to deal with various hyperimmune-associated disorders as well as tumor growth, although the latter still remains unclear. This review focuses on studies of the molecules released by T. spiralis, their interaction with pattern recognition receptors on antigen presenting cells, and subsequently provoked responses. This paper also addresses the immunomodulatory properties of ES L1 molecules and how the induced immunomodulation influences the course of different experimental inflammatory and malignant diseases.

Abstract
The co-evolution of a wide range of helminth parasites and vertebrates represented a constant pressure on the host's immune system and a selective force for shaping the immune response. Modulation of the immune system by parasites is accomplished partly by dendritic cells. When exposed to helminth parasites or their products, dendritic cells do not become classically mature and are potent inducers of Th2 and regulatory responses. Treating animals with helminths (eggs, larvae, extracts) causes dampening or in some cases prevention of allergic or autoimmune diseases. Trichinella spiralis (T. spiralis) possess a capacity to retune the immune cell repertoire, acting as a moderator of the host response not only to itself but also to third party antigens. In this review, we will focus on the ability of T. spiralis-stimulated dendritic cells to polarize the immune response toward Th2 and regulatory mode in vitro and in vivo and also on the capacity of this parasite to modulate autoimmune disease--such as experimental autoimmune encephalomyelitis.

Abstract
Endothelial-like differentiation of dendritic cells (DCs) is a new phenomenon, and the mechanism is still elusive. Here, we show that the tumor microenvironment derived from the human esophageal squamous cell carcinoma (ESCC) cell line EC9706 can induce immature DCs (iDCs) differentiate toward endothelial cells, and become endothelial-like cells, but it has no obvious influence on mature DCs. During the course of endothelial-like differentiation of iDCs, a sustained activation of mitogen-activated protein kinase/extracelluar signal-regulated kinase1/2 (MAPK/ERK1/2) and cAMP response element-binding protein (CREB) was detected. Incubation of iDCs with MEK phosphorylation inhibitor PD98059 blocked the MAPK/ERK1/2 and CREB phosphorylation as well as the endothelial-like differentiation of iDCs. Inhibition of vascular endothelial growth factor-A (VEGF-A) in the microenvironment with its antibody blocked the endothelial-like differentiation and the phosphorylation of MAPK/ERK1/2 and CREB. These data suggest that MAPK/ERK1/2 signaling pathway activated by VEGF-A could mediate endothelial-like differentiation of iDCs in the ESCC microenvironment.

Abstract
The evolving realization that stress proteins, which have for many years been considered to be exclusively intracellular molecules under normal conditions, can be released from viable cells via a number of potential routes/pathways has prompted interest into their extracellular biology and intercellular signaling properties. That the stress proteins Hsp60, Hsp70 and gp96 can elicit both pro- and anti-inflammatory effects suggests that these molecules play a key role in the maintenance of immunological homeostasis, and a better understanding of the immunobiology of extracellular stress proteins might reveal new and more effective approaches for controlling and managing infectious disease, inflammatory disease and cancer. A number of cell surface receptors for stress proteins have been identified, and the intracellular consequences of these cell surface receptor-ligand interactions have been characterized. To date, studies into the intercellular signaling properties of stress proteins and their interactions with antigen presenting cells have focused on specific receptor-mediated uptake, and have not considered the fact that such cells can also take up proteins via non-specific endocytosis/pinocytosis. Herein we present a methodological approach for assessing receptor-mediated and non-receptor-mediated uptake of gp96 by rat bone marrow-derived dendritic cells.

Abstract
Although low doses of tumor-derived stress protein gp96 elicit protective immunity to the tumor from which it is isolated, protection is lost at high doses because of the induction of immunoregulatory CD4+ T cells. This study evaluated the influence of gp96 on resting rat bone marrow-derived dendritic cells (BMDCs) and purified CD3+ T cells. In contrast to previous reports, gp96 had no effect on adhesion and costimulatory molecule expression by BMDCs, nor did it influence interleukin (IL)-10 and IL-12 secretion or their allostimulatory capacity. Gp96 did not bind to BMDCs but dose-dependently bound to CD4+ and CD8+ T cells. At low concentrations (1 and 25 microg/mL), gp96 acted as a costimulator of CD3+ T cells, inducing proliferation and the secretion of interferon (IFN)-gamma- and IL-10. Gp96 also increased the proliferation of CD28-costimulated CD3+ T cells and their secretion of IFN-gamma, IL-4, and IL-10. Gp96 had no effect at higher concentrations (50 and 100 microg/mL), despite the occurrence of cell surface binding at these concentrations. These findings indicate that gp96 can act as a costimulatory molecule for CD3+ T cells, and an observed increase in the IL-10: IFN-gamma secretion ratio induced by gp96 suggests that it might, at appropriate concentrations, promote a regulatory T-helper 2 (Th2)-like phenotype.
