Abstract
Dendritic cells (DCs) play an important role in immunity by sensing and responding to invasive microbes. Bacillus species are rod-shaped sporulating bacteria that include the pathogenic Bacillus cereus and commensal Bacillus subtilis. Although the interaction between DC and these two Bacillus species has been studied, their key structural component that prompts DC activation is poorly understood. Here, we investigated the two Bacillus species in DC activation by whole cells and their representative microbe-associated molecular patterns (MAMPs). MAMPs including lipoteichoic acid (LTA), lipoprotein (LPP), and peptidoglycan (PGN) were purified from the two Bacillus species. Among the MAMPs, LPP from both species most potently induced the maturation and activation of DCs while PGN, but not LTA, moderately stimulated DCs. LPPs from both Bacillus species enhanced the expression of DC maturation markers including CCR7, CD40, CD80, CD83, CD86, CD205, MHC-I, and MHC-II. Among the MAMPs from B. cereus, PGN most considerably lowered the endocytic capacity of DCs implying DC maturation whereas PGN from B. subtilis lowered it to a similar degree to its LPP. Furthermore, DCs sensitized with LPPs from both Bacillus species and PGN from B. subtilis moderately induced TNF-α and IL-6 production. Notably, a combination of MAMPs did not show any synergistic effect on DC activation. Taken together, our results demonstrate that LPP is the key structural component in B. cereus and B. subtilis that leads to DC activation.

Abstract
β-glucans represent a heterogeneous group of naturally occurring and biologically active polysaccharides found in many kinds of edible mushrooms, baker’s yeast, cereals and seaweeds, whose health-promoting effects have been known since ancient times. These compounds can be taken orally as food supplements or as part of daily diets, and are safe to use, nonimmunogenic and well tolerated. A main feature of β-glucans is their capacity to function as biological response modifiers, exerting regulatory effects on inflammation and shaping the effector functions of different innate and adaptive immunity cell populations. The potential to interfere with processes involved in the development or control of cancer makes β-glucans interesting candidates as adjuvants in antitumor therapies as well as in cancer prevention strategies. Here, the regulatory effects of dietary β-glucans on human innate immunity cells are reviewed and their potential role in cancer control is discussed.

Abstract
Various exciting immunotherapies aiming to address immune deficiency induced
by tumor and treatment hold promise in improving the quality of life and survival
rate of cancer patients. It is thus becoming an important and rewarding arena to develop
some appropriate immune modulators for cancer prevention and/or treatment. Exploitation
of natural products-based immune modulators is of particular imperative because the
potential of numerous traditional herbal medicines and edible mushrooms in boosting
human immune system has long been verified by folklore practices. This review summarizes
the immune modulations of various herbal medicines and edible mushrooms, their
crude extracts, and/or key chemical components that have been, at least partly, associated
with their cancer management. This article also tabulates the origin of species, key
chemical components, and clinical studies of these herbal medicines and edible mushrooms.

Abstract
The culinary and medicinal mushroom Hericium erinaceus is widely consumed in Asian countries, but apparently not in the United States, for its nutritional and health benefits. To stimulate broader interest in the reported beneficial properties, this overview surveys and consolidates the widely scattered literature on the chemistry (isolation and structural characterization) of polysaccharides and secondary metabolites such as erinacines, hericerins, hericenones, resorcinols, steroids, mono- and diterpenes, and volatile aroma compounds, nutritional composition, food and industrial uses, and exceptional nutritional and health-promoting aspects of H. erinaceus. The reported health-promoting properties of the mushroom fruit bodies, mycelia, and bioactive pure compounds include antibiotic, anticarcinogenic, antidiabetic, antifatigue, antihypertensive, antihyperlipodemic, antisenescence, cardioprotective, hepatoprotective, nephroprotective, and neuroprotective properties and improvement of anxiety, cognitive function, and depression. The described anti-inflammatory, antioxidative, and immunostimulating properties in cells, animals, and humans seem to be responsible for the multiple health-promoting properties. A wide range of research advances and techniques are described and evaluated. The collated information and suggestion for further research might facilitate and guide further studies to optimize the use of the whole mushrooms and about 70 characterized actual and potential bioactive secondary metabolites to help prevent or treat human chronic, cognitive, and neurological diseases.

Abstract
Hericium erinaceus is an important mushroom with edible values and medicinal properties. Both the mycelium and the fruiting bodies contain many bioactive compounds with drug efficacy. Recent evidence demonstrates that it is helpful to various diseases, such as Alzheimer's disease, immunoregulatory, and many types of cancer. Furthermore, emerging pieces of evidence have shown that different active molecules in H. erinaceus have different functions on different organs in different diseases via the different mechanisms. Drawing on current research results, this review mainly focuses on the therapeutic effects of H. erinaceus on various diseases of multiple physiological systems, including the nervous system, digestive system, circulatory system, and immune system. This paper also discusses systematically the efficient protection of H. erinaceus against the diseases from the intricate experimental proofs by using the systematic viewpoints, which provides a framework for future research directions.

Abstract
During adaptive immunity to pathogens, dendritic cells (DCs) capture, kill, process, and present microbial Ags to T cells. Ag presentation is accompanied by DC maturation driven by appropriate costimulatory signals. However, current understanding of the intricate regulation of these processes remains limited. Cryptococcus gattii, an emerging fungal pathogen in the Pacific Northwest of Canada and the United States, fails to stimulate an effective immune response in otherwise healthy hosts leading to morbidity or death. Because immunity to fungal pathogens requires intact cell-mediated immunity initiated by DCs, we asked whether C. gattii causes dysregulation of DC functions. C. gattii was efficiently bound and internalized by human monocyte-derived DCs, trafficked to late phagolysosomes, and killed. Yet, even with this degree of DC activation, the organism evaded pathways leading to DC maturation. Despite the ability to recognize and kill C. gattii, immature DCs failed to mature; there was no increased expression of MHC class II, CD86, CD83, CD80, and CCR7, or decrease of CD11c and CD32, which resulted in suboptimal T cell responses. Remarkably, no increase in TNF-α was observed in the presence of C. gattii. However, addition of recombinant TNF-α or stimulation that led to TNF-α production restored DC maturation and restored T cell responses. Thus, despite early killing, C. gattii evades DC maturation, providing a potential explanation for its ability to infect immunocompetent individuals. We have also established that DCs retain the ability to recognize and kill C. gattii without triggering TNF-α, suggesting independent or divergent activation pathways among essential DC functions.

Abstract
The effects of different particle sizes (100-150, 74-100, and <74 μm) of powder of the dried and ground stipe from the monkey head mushroom, Hericium erinaceum, on the immune response and disease resistance of white shrimp, Litopenaeus vannamei, against the pathogen, Vibrio alginolyticus, were examined. Mushroom powder with a particle size of <74 μm had a significantly higher effect on the disease resistance of shrimp compared to particle sizes of >74 μm. Mortality of shrimp after being injected with V. alginolyticus was particle size-dependent, increasing from 66.7% ± 3.3%-93.3% ± 3.3% with diets containing stipe particle sizes of <74 and 100-150 μm, respectively. The mortality of shrimp fed the diet containing <74-μm stipe powder for 28 days was significant lower than that of shrimp fed with the control diet and the diet containing 74-100-μm stipe powder after being challenged by V. alginolyticus. The optimal concentration of the <74-μm mushroom powder for enhancing the immune response and disease resistance of shrimp was 0.2 μg (g shrimp)(-1) day(-1). No significant change in the total hemocyte count, differential hemocyte count, glutathione reductase, or phagocytic activity was found in shrimp fed the control diet and mushroom powder-containing diet at a level of up to 0.2 μg (g shrimp)(-1) day(-1). Shrimp fed 0.2 μg (g shrimp)(-1) day(-1) of a mushroom-containing diet had a significantly higher disease resistance to V. alginolyticus via an increase in phenoloxidase activity, respiratory bursts, superoxide dismutase activity, and glutathione peroxidase activity. Therefore, a diet containing the stipe powder of monkey head mushroom with a particle size <74 μm at a level of 0.2 μg (g shrimp)(-1) day(-1) was found to enhance the immunity and disease resistance of shrimp.

Abstract
AIM OF THE STUDY Hericium erinaceum is a medicinal mushroom that has been traditionally used in Asian countries for the treatment of cancers and infectious diseases. Although the immunomodulating activity of H. erinaceum is considered to be responsible for its medicinal activity, its action mechanisms are poorly understood. In the present study, we investigated the capability of water-extracted H. erinaceum (WEHE) to induce the expression of intercellular adhesion molecule-1 (ICAM-1), which regulates the migration of immune cells. MATERIALS AND METHODS THP-1, a human monocytic cell-line, or human peripheral blood mononuclear cells (PBMC) were stimulated with WEHE (0-30 μg/mL) and subsequently analyzed using flow cytometry to examine the surface expression of ICAM-1 protein. Steady-state levels of ICAM-1 mRNA were estimated using real-time reverse transcription-polymerase chain reaction analysis. Electrophoretic mobility shift assay was conducted to examine transcription factors involved in ICAM-1 transcription. RESULTS WEHE induced ICAM-1 expression at both protein and mRNA levels in THP-1 cells in a dose- and time-dependent fashion. A similar pattern of ICAM-1 induction was also observed in CD14(+) monocytes in human PBMC that were stimulated with WEHE. The ICAM-1 expression on THP-1 cells stimulated with WEHE was suppressed by specific inhibitors for extracellular signal-regulated kinases (ERK) and reactive oxygen species (ROS). Additionally, exposure of THP-1 cells to WEHE increased the DNA binding activities of NF-κB, AP-1, SP-1 and STAT-1 transcription factors, all of which are known to be required for ICAM-1 gene expression. CONCLUSIONS These results suggest that WEHE induces ICAM-1 expression in human monocytes through ERK- and ROS-dependent signaling pathways, resulting in the subsequent activations of NF-κB, AP-1, SP-1, and STAT-1 transcription factors.
