Abstract
This study identified characteristic whey proteins from Zhongdian Yak (ZY), Diqing Yellow Cattle (DYC), and Cattle Yak (CY), revealing insights into their potential functions and released peptides. A total of 118 whey proteins were quantified in milk obtained from the three breeds of cattle, including seven characteristic proteins (IGL@ protein, 40S ribosomal protein S9, calreticulin, etc.) in CY milk and two characteristic proteins (RNA helicase and uncharacterized protein (A0A3Q1LFQ2)) in ZY milk. These characteristic proteins are involved in the phagosome and Fc gamma R-mediated phagocytosis pathways, exhibiting immunoprotective activities, verified through molecular docking. Furthermore, the molecular docking results showed five whey proteins (IGL@ protein, rho GDP-dissociation inhibitor 1, small monomeric GTPase, action-like protein 3, and adenylyl cyclase-associated protein) interacted with TLR4 through multiple hydrogen and hydrophobic bonds. Therefore, these proteins may exert immunomodulatory functions by inhibiting TLR4. Meanwhile, whey proteins produced bioactive peptides, such as antioxidant peptides and ACE inhibitory peptides after simulated gastrointestinal digestion (SGID). The whey proteins and bioactive peptides from CY exhibited more types and activities than the ZY and DYC whey proteins. This study provides a theoretical basis for promoting formula milk powder production.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Caragana sinica (Buc'hoz) Rehd. is a plant widely grown in Yunnan, China, for both medicinal and edible purposes. The "National Compilation of Chinese Herbal Medicine" describes its nature as "slightly temperate and sweet". Caragana sinica is usually medicated with whole herbs, the main function is to replenish the kidneys and stop bleeding. Caragana sinica was used in folk medicine in Chuxiong, Yunnan, to treat deficiency colds, fatigue, fever, cough, hypertension, and other diseases. AIM OF THE STUDY This article investigates the structural characteristics of Caragana sinica polysaccharide (CSP) and explores its immune-regulatory activity and molecular biological mechanisms in cyclophosphamide-induced immunosuppressed mice, as well as its effects on intestinal bacteria. METHODS With the water-extraction and alcohol-precipitation method, Caragana sinica polysaccharide were extracted, obtaining CSP by purification. A variety of methods and techniques have been used to analyze the chemical properties and structural characteristics of CSP. Immunosuppressive mice model was established through intraperitoneal injection of cyclophosphamide (CTX) to study the immune-regulatory effects and mechanisms of CSP. RESULTS The data indicated that CSP is a neutral heteropolysaccharide mainly composed of arabinose and galactose. This article uses immunosuppressive mice induced by cyclophosphamide (CTX) as the model. The results showed that CSP can promote the immune function of CTX treated immunosuppressed mice and regulate the diversity and composition of intestinal microbiota. CSP can increase macrophage phagocytosis, NK cell killing activity, and lymphocyte proliferation activity. It can also repair the index and morphological damage of the thymus and spleen. And by binding to the TLR4 receptor, MyD88 was activated and interacted with TRAF6 to promote the transfer of NF-κB into the nucleus. Thereby promoting cytokine release and increasing the production of IL-1β, IL-6, IL-10, TNF-α, IgA, and IgG in the serum. CSP also effectively alleviated the liver damage caused by CTX through antioxidant activity. Furthermore, CSP can dramatically affect the intestinal microbiota and the body's immunity by boosting the relative presence of Bacteroides and Verrucamicrobiota. CONCLUSIONS Research results indicated that CSP can regulate the immune function of mice, providing a basis for developing CSP as a potential immune modulator and functional food.

Abstract
Interests in the development and exploration of industrial applications of medicinal mushrooms as postbiotics have lately increased. We recently reported the potential use of Phellinus linteus mycelial-containing whole culture extract (PLME) prepared by submerged cultivation as a postbiotic that promotes immune system activation. Here, we aimed to isolate and structurally elucidate the active ingredients in PLME by activity-guided fractionation. The intestinal immunostimulatory activity was evaluated by bone marrow (BM) cell proliferation activity and related cytokine production in C3H-HeN mouse-derived Peyer's patch (PP) cells treated with polysaccharide fractions. The initially crude polysaccharide (PLME-CP) of PLME prepared using ethanol precipitation was further fractionated into four fractions (PLME-CP-0 to -III) by anion-exchange column chromatography. BM cell proliferation and cytokine production of PLME-CP-III were significantly improved compared to those of PLME-CP. PLME-CP-III was then fractionated into PLME-CP-III-1 and PLME-CP-III-2 by gel filtration chromatography. Based on the molecular weight distribution, monosaccharide, and glycosyl linkage analyses, PLME-CP-III-1 was revealed as a novel galacturonic acid-rich acidic polysaccharide and further shown to play an important role in facilitating PP-mediated intestinal immunostimulatory activity. This is the first study demonstrating the structural characteristics of a novel intestinal immune system modulating acidic polysaccharide from P. linteus mycelium-containing whole culture broth postbiotics.

Abstract
Antimicrobial peptides (AMPs) play important roles in the immune defense against pathogenic microorganisms. For instance, histone 2A (H2A)-derived AMPs is an antimicrobial peptide involved in the host's innate immune defense and immunoregulation. AMPs have been isolated from the pearl oyster Pinctada fucata martensii but their role in host defense remains poorly understood. To elucidate the structural features of P. f. martensii H2A (PmH2A)-derived AMPs and their potential immune functions, we synthesized a series of laboratory-designed synthetic analogs of PmH2A and examined their antimicrobial properties, as well as their mechanisms of action. This analysis revealed inhibitory effects on the growth of Gram-positive and Gram-negative bacteria. Further assessment by transmission electron microscopy (TEM) of two of the three peptides, PmH2A-AMP and PmH2A-AMP(5-13)[KLLK]3, confirmed that it exerted an anti-bacterial activity through membrane lysis. Finally, we found that the hemocytes and gills of P. f. martensii released antimicrobial H2A histones in response to LPS exposure, mimicking tissue damage and infection. This immune response is reminiscent of the neutrophil extracellular traps (NETs) recently described in oysters. Thus, the LPS challenge is sufficient to induce histone-derived peptide accumulation in pearl oyster P.f. martensii.

Abstract
Xylo-oligosaccharides (XOS) prepared by the acetic acid hydrolysis of corncob were adulterated with many impurities including pigments, salts, and monosaccharides. Monosaccharides, acids, and most of the pigment were removed by a combination of decolorization, bipolar membrane electrodialysis and catalysis by Gluconobacter oxydans. These steps retain 90% of XOS in the acidolysis slurry. In this study, the effects of purified-XOS (PXOS) and crude XOS (CXOS) on the antioxidant and immune activities of macrophage were compared to verify the bioactivity of acidic hydrolyzed XOS, mainly focusing on the benefits of the purification process. PXOS was more effective in increasing superoxide dismutase activity and reducing malondialdehyde content, and thus had more potent antioxidant activity. In addition, PXOS could more efficiently promote the secretion of tumor necrosis factor-α, interleukin-6, nitric oxide, and interleukin-1β by macrophage. All these data, suggest that the purification process contributed to improve the immunomodulatory activity of XOS from acidolysis slurry.

Abstract
BACKGROUND IgA nephropathy (IgAN) is one of the most common forms of chronic glomerulonephritis, but the aetiology and pathogenesis remain unclear. Cuproptosis is a newly identified form of cell death that plays an important role in many diseases. Researchers have not clearly determined whether the expression of cuproptosis-related genes (CRGs) is involved in the pathogenesis of IgAN. METHODS The GSE93798, GSE50469 and GSE37460 datasets containing microarray data from patients with IgAN (63) and healthy controls (31) were downloaded from the GEO database. Immune cells and immune-related functions were analysed in patients with IgAN and controls, and genes were identified that may be related to cuproptosis. A logistic regression model was established according to the results, and then GO and KEGG enrichment analyses were performed. Finally, possible drugs were selected using the DSigDB database. RESULTS The subjects in the different groups showed significantly different fractions of immune cells and immune-related functions, and 11 genes related to cuproptosis may be involved in these processes. Based on these 11 genes, the ROC curve was plotted, and the AUC value was calculated (0.898, 95% CI: 0.839-0.958). The result revealed good predictability. Then, genes with P < 0.05 (lipoyltransferase 1, LIPT1) were selected to plot an ROC curve, and the AUC value was calculated (0.729, 95% CI: 0.636-0.821). Enrichment analyses showed that the TCA cycle and multiple metabolic pathways may also be involved in the occurrence of IgAN. Finally, 293 potential drugs that may be used to treat IgAN were identified based on these genes. CONCLUSION In this study, we identified some novel CRGs that may be involved in IgAN, among which LIPT1 was significantly differentially expressed. It may predict the risk of IgAN and provides a possible target for the treatment of IgAN. Further experimental studies are needed to explore how these CRGs mediate the occurrence and development of IgAN.

Abstract
The purpose of this study was to investigate the effects of chitosan graphene oxide Codonopsis pilosula polysaccharide (CS-GO-CPP) complex on the immune function of macrophage cells (RAW264.7). In this experiment, chitosan (CS) was combined with graphene oxide (GO) by electrostatic action to prepare CS-GO nanocomposites, and it was used as a carrier to load Codonopsis pilosula polysaccharide (CPP) onto CS-GO to prepare CS-GO-CPP. Using infrared spectroscopy detection, zeta potential detection, and thermogravimetric analysis, we conduct a preliminary analysis of the structure of CS-GO-CPP. Macrophages were employed to evaluate CS-GO-CPP immunomodulatory activity and the possible mechanism responsible for the activation of macrophages in vitro. The results showed that compared with CPP, CS-GO-CPP did not change the basic structure of polysaccharide, and its thermal stability was improved. 0.78- 12.5 μg·mL-1 of CS-GO-CPP could significantly promote the phagocytic activity of RAW264.7 cells (P < 0.05) and significantly increase NO content, IL-4 and IFN-γ secretion, the expression of CD40, CD86, and F4/80 (P < 0.05). CS-GO-CPP might activate the NF-κB signaling pathway and induce the nuclear translocation of NF-κB p65. In conclusion, CS-GO-CPP has a capacity to activate RAW264.7 cells for an improvement of immunomodulation activities, which might be through NF-κB signaling pathway.

Abstract
As an essential trace element, appropriate boron supplementation can promote immune function of animals. To illustrate the effects of boron in a rat model, RNA-Seq was conducted for the RNA from duodenum after treatment with different concentration of boron in which boron was given in the form of boric acid. More than 47 million reads were obtained in 0, 10, and 320 mg/L boron (0, 57.21, and 1830.66 mg/L boric acid) treatment groups that produced 58 965 402, 48 607 328, and 46 760 660 clean reads, respectively. More than 95% of the clean reads were successfully matched to the rat reference genome and assembled to generate 32 662 transcripts. A total of 624 and 391 differentially expressed candidate genes (DEGs) were found between 0 vs.10 and 0 vs. 320 mg/L boron comparison groups. We also identified transcription start site, transcription terminal site, and skipped exons as the main alternative splicing events. GO annotations revealed most of DEGs were involved in the regulation of immune activity. The DEGs were enriched in influenza A, herpes simplex infection, cytosolic DNA-sensing pathway, and antigen processing and presentation signaling pathways. The expression levels of genes enriched in these signaling pathways indicate that lower doses of boron could achieve better effects on promoting immune response in the duodenum. These effects on the immune system appear to be mediated via altering the expression patterns of genes involved in the related signaling pathways in a dose-dependent pattern. These data provide more insights into the molecular mechanisms of immune regulation in rats in response to dietary boron treatment.

Abstract
The root bark of Ulmus davidiana var. japonica (Rehder) Nakai (Japanese elm) has been used for inflammatory disease treatments. In this work, we isolated pectic polysaccharides from the root bark of U. davidiana (UDP) and explored the immune activities of intact and ultrasonicated UDP on human macrophages. The UDP-treated macrophages showed a proinflammatory response, indicating classical activation via Toll-like receptor-mediated recognition. For hydrogel formation, the ultrasonicated UDP was modified with methacrylate groups, then subjected to photocrosslinking. The formed bulk hydrogel was pulverized into microgels by homogenization, and the microgel size was modulated for macrophage phagocytosis. The UDP microgel-treated macrophages displayed microgel internalization and classical activation that involved upregulation of M1 polarization markers (IL6, TNF-α, and CCR7), indicating that the microgel can be used as a carrier for macrophage-targeted drug delivery.

Abstract
Polysaccharides coded as CP were extracted from Athyrium Multidentatum (Doll.) Ching and then fractionated into five fractions (FP-1, FP-2, FP-3, FP-4 and FP-5). A purified polysaccharide designated as FP-3-4 was prepared from FP-3 by Sephadex G-100 column chromatography. Chemical analysis disclosed that CP and these fractions were heteropolysaccharides and mainly composed of glucose, galactose, arabinose, mannose, rhamnose, xylose, fucose, ribose and uronic acid with different molar ratios. They presented different images of SEM. FP-3-4 was highly branched polymers with sixteen types of linkages. The in vitro immunomodulatory results stated that CP and these fractions could promote macrophage proliferation, enhance macrophage phagocytosis and increase the production of NO, TNF-α, IFN-γ, IL-1β, IL-6, IL-10 and IL-2, indicating remarkable immune enhancement activities. RNA sequencing analysis revealed that CP and FP-3 induced macrophage activation mainly through MAPK and alternative NF-κΒ signaling pathways via CD14/TLR4 and Dectin-2 receptors, which were verified by RT-qPCR and western blot.

Abstract
A new type of acidic exopolysaccharide (AESP-II) was extracted and separated from the fermentation broth of Cordyceps militaris (C. militaris), which was further purified to elucidate its structural characteristics and immunological activity. AESP-II was confirmed to be an acidic pyranose with a molecular weight of 61.52 kDa, which consisted of mannose, glucuronic acid, rhamnose, galactose acid, N-acetyl-galactosamine, glucose, galactose and arabinose with a molar ratio of 1.07: 5.38: 1: 3.14: 2.23: 15: 6.09: and 4.04. Animal experiment results verified that AESP-II can significantly promote the proliferation of spleen T and B lymphocytes in mice with immune injury caused by cyclophosphamide (CTX). In particular, the promotion of B lymphocytes presented a dose-effect relationship. In addition, the levels of the cytokines IL-2, IL-4, and IFN-γ, which are mainly secreted by T lymphocytes, and immunoglobulin IgG, IgM and IgA, which are mainly secreted by B lymphocytes, were increased after AESP-II treatment. The above results suggest that fluid immunity is involved in the immunomodulatory function of AESP-II. Simultaneously, AESP-II was detected significantly to promote the phosphorylation expression of p38 kinase (p38), extracellular regulated protein kinases (ERK) and c-Jun N-terminal kinase (JNK) by Western blot, further suggesting that the activation of the MAPK signaling pathway mediates the immunoregulatory function of AESP-II.

Abstract
A quantitative comparison of the proteomes during different periods of the formation of egg yolk, from yellow follicles (YF), small hierarchical follicles (9-12 mm, SF), and the largest hierarchical follicle (LF), was performed. The abundance of major egg yolk proteins (apolipoprotein B and vitellogenins) changed significantly during the yolk formation, and several protein hydrolases and isomerases, which may be related to the processing of egg yolk proteins, also varied significantly. The binding proteins for three vitamins (retinol, riboflavin, and vitamin D) and cholesterol were all most abundant in the LF period, suggesting that these nutrients were transported mainly at the final period of the egg yolk formation. Immunoglobulins decreased and complement proteins increased as formation progressed, indicating the dynamic nature of the egg yolk immune system. These results are helpful for understanding the nutrient composition, the formation of assembly structure, the preservation and processing properties of egg yolk.

Abstract
Cordyceps is one of the most expensive and widely used functional foods. But the authenticity is still a concern due to the lack of appropriate markers. By targeting polysaccharides, this study aimed to develop a specific, and bioactive marker for Cordyceps. Firstly, the results of screening tests of 250 samples by examining both genetic markers and polysaccharide profile showed that a unique polysaccharide fraction (named CCP) was particular to the caterpillar parts. Its potential as a marker was further demonstrated by its ability to induce NO and cytokine production in RAW 264.7 cells. CCP was characterized to be an α-1,4-glucan with a branch at C-6 by the conventional structure analyzing and de novo oligosaccharides sequencing. The content of CCP was closely correlated to the traditional classification criteria. Generally, CCP was a marker that simultaneously enables qualitative and quantitative analysis of Cordyceps.

Abstract
Neonatal lipopolysaccharide (LPS) exposure can cause depressive-like behaviors in rodents involving elevated interferon (IFN)-γ. Studies have linked down-regulation of prefrontal cortex (PFC) ATPase phospholipid transporting 8A2(ATP8A2) expression to depressive-like behaviors. In non-neuronal cells, IFN-γ could reduce ATP8A2 expression. Therefore, we hypothesized that neonatal LPS exposure might induce PFC ATP8A2 down-regulation by increasing the IFN-γ level. Here, C57BL6/J mice of both sexes received 3-dose-injections of LPS (50 μg/kg body weight, i.p.) on postnatal day (PND)5, PND7, and PND9. LPS-treated mice showed a transiently decreased PFC ATP8A2 expression indicated by western blot results. Moreover, a significant negative correlation of PFC ATP8A2 expression was found with the IFN-γ level. Using neutralizing mAb, IFN-γ was identified as the key mediator of LPS-induced PFC ATP8A2 decrease indicated by western blot and immunofluorescence results. In sum, neonatal LPS exposure reduced ATP8A2 level in PFC in mice via increasing IFN-γ level. This finding may help further understand the mechanism underlying LPS-induced impairments in brain development and function.

Abstract
Caseinate was glycated with oligochitosan via transglutaminase (TGase) action and then hydrolyzed by trypsin to generate glycated caseinate hydrolysate (GCNH) that was investigated for in vivo immune-promoting activity. Caseinate hydrolysate (CNH) containing glucosamine of 5.7 g/kg had amino acid compositions similar to GCNH. In normal BALB/c mice, GCNH at 100-400 mg/(kg d) showed higher immune-promoting activity than CNH via increasing serum IgM, IgA, and IgG by 1.5-24.5%, enhancing spleen and thymus indices by 9.7-26.2%, or increasing splenocyte lymphocyte proliferation and natural killer (NK) cell activity by 1.2-11.5%. GCNH also exerted higher activity than CNH in the suppressed BALB/c mice through increasing serum IgM, IgA, and IgG by 2.6-10.5%, enhancing spleen and thymus indices by 0.4-50.1%, or increasing splenocyte lymphocyte proliferation and NK cell activity by 3.4-18.9%. The results highlight that this TGase-type oligochitosan-glycation is potential to generate functional protein ingredients that possess improved immune-promoting activity once hydrolyzed by trypsin.

Abstract
CCL21 promotes immune activity in the tumor microenvironment (TME) by colocalizing dendritic cells (DC) and T cells programing ectopic lymph node architectural structures that correlate with cancer prognosis. Innovative strategies to deliver CCL21 in cancer patients will reactivate the downregulated immune activity in the TME. Immune escape mechanisms are upregulated in the TME that promote tumor immune evasion. CCL21 combined with inhibition of dominant pathways of immune evasion will aid in the development of effective immunotherapy for cancer.

Abstract
In order to improve the hydrophilicity and immune activity of the polysaccharide from Dendrobium nobile Lindl., non-thermal plasma was used to treat the polysaccharide. It was found that the hydrophilicity of the polysaccharide plasma-treated was significantly enhanced. Infrared spectra showed that the content of OH in the molecule increased significantly, and the monosaccharide ring changed from β-pyran sugar to β-furan sugar. The detection of SEM, AFM and TEM showed that the degree of cross-linking of surface molecules increased, and the arrangement of the polysaccharide was more compact and orderly. In vitro cell tests showed that the polysaccharide plasma-treated significantly improve the phagocytosis ability of RAW264.7, and promote the secretion of cytokines TNF-α, IL-6, IL-1. However, the cell proliferation test indicated that the polysaccharide did not increase the concentration of cytokines by promoting cell proliferation. RT-PCR showed that the polysaccharide plasma-treated could promote the expression of IL-1β at the transcriptional level. These results showed that non-thermal plasma treatment can effectively enhance the hydrophilicity of the polysaccharide and enhance its immune activity in vitro. Therefore, it can be inferred that the non-thermal plasma technology can be applied to the modification of active polysaccharides and will promote active polysaccharides to work better.

Abstract
The aquaculture industry has developed rapidly in recent years, and in China Crayfish Procambarus clarkii represent an important aquaculture fishery. However, bacterial and viral diseases are becoming an increasingly serious threat, causing considerable economic losses. Farmers use a large number of drugs and chemicals to destroy pathogenic microorganisms and to purify aquaculture water. The purpose of this study was to assess the effects of such drugs on crayfish immune systems. Five of the most commonly used fishery drugs and water treatment chemicals were analyzed: norfloxacin, calcium hypochlorite, quick lime, povidone iodine and copper sulfate. Crayfish immune activity tests revealed that total hemocytes counts, as well as the activities of phenoloxidase and superoxide dismutase, decreased following exposure to all five treatments. These treatments, especially calcium hypochlorite and norfloxacin, significantly enhanced hemocyte apoptosis in crayfish, regardless of disease status. Calcium hypochlorite, in particular, led to a significant decrease in the survival rates of crayfish infected with white spot syndrome virus or Vibrio alginolyticus. Our results indicate that water treatment and disease control compounds commonly used in aquaculture can reduce the innate immunity and therefore disease resistance of crayfish.

Abstract
Objective: To investigate the percentage of myeloid-derived suppressor cells (MDSC) and T regulatory cells (Treg) in peripheral blood of nasopharyngeal cancer (NPC) patients undergoing concurrent chemoradiotherapy or radiotherapy alone. Methods: Sixty NPC patients who received radiotherapy or concurrent chemoradiotherapy from September 2012 to November 2015 and 20 healthy individuals were included in this study. For the patients, the blood samples were collected at four time points: pre-radiation (Pre-RT), reaching a dose of 40 Gy (RT-40 Gy), finishing radiation (RT-finish) and three months after finishing radiation (3m-post-RT). Flow cytometry was used to evaluate the percentage of Treg (CD4(+) CD25(+) CD127(low/-)) and MDSC (HLA-DR(-)CD11b(+) CD33(+) ) cells in peripheral blood. Results: Treg and MDSC cells were present in peripheral blood lymphocytes of healthy individuals as a percentage of (7.50±1.62)% and (1.08±0.48)%, respectively. The proportions of peripheral Treg cells in patients at Pre-RT, RT-40 Gy, RT-finish and 3m-post-RT time points were (8.42± 1.52)%, (9.10±1.57)%, (8.87±1.56)% and (7.31±1.43)%, respectively, showing a statistically significant difference between Pre-RT and the other groups (P<0.05). At Pre-RT point, the percentage of Treg cells in Stage Ⅲ-Ⅳ patients [(8.63±1.39)%] was higher than that in Stage Ⅰ-Ⅱ [(7.65±1.94)%, P=0.042]. Moreover, the proportions of peripheral MDSC cells in patients at Pre-RT, RT-40 Gy, RT-finish and 3m-post-RT time points were (2.14±1.21)%, (4.08±1.90)%, (3.76±1.31)% and (1.52±0.88)%, respectively. The percentages of MDSC cells at RT-40 Gy and RT-finish points were significantly higher than those at Pre-RT, while the percentage of MDSC cells at 3m-post-RT was significantly lower than those at Pre-RT (P<0.05). At Pre-RT point, the percentage of MDSC cells in Stage Ⅲ-Ⅳ patients [(2.25±1.26)%] was higher than that in Stage Ⅰ-Ⅱ [(1.35±0.66)%, P=0.007]. At RT-finish point, the proportions of MDSC and Treg cells in patients with Ⅲ-Ⅳ grade of radiation induced oral mucositis [(4.41±1.27)% and (9.91±1.23)%] were significantly higher than those in Ⅰ-Ⅱ grade patients [(3.15±1.04)% and (8.41±1.52)%, both of P<0.05]. Conclusions: The proportions of MDSC and Treg cells in initial treated NPC patients are higher than healthy individuals, and they are also associated with the tumor stages. During the concurrent chemoradiotherapy and radiation, the percentage of MDSC and Treg cells is elevated, suggesting a decreased immune activity. The increase of MDSC and Treg cells is related to radiation induced oral mucositis.

Abstract
Aquatic animals are frequently suffered from starvation due to restricted food availability or deprivation. It is currently known that gut microbiota assists host in nutrient acquisition. Thus, exploring the gut microbiota responses would improve our understanding on physiological adaptation to starvation. To achieve this, we investigated how the gut microbiota and shrimp digestion and immune activities were affected under starvation stress. The results showed that the measured digestion activities in starved shrimp were significantly lower than in normal cohorts; while the measured immune activities exhibited an opposite trend. A structural equation modeling (SEM) revealed that changes in the gut bacterial community were directly related to digestive and immune enzyme activities, which in turn markedly affected shrimp growth traits. Notably, several gut bacterial indicators that characterized the shrimp nutrient status were identified, with more abundant opportunistic pathogens in starved shrimp, although there were no statistical differences in the overall diversity and the structures of gut bacterial communities between starved and normal shrimp. Starved shrimp exhibited less connected and cooperative interspecies interaction as compared with normal cohorts. Additionally, the functional pathways involved in carbohydrate and protein digestion, glycan biosynthesis, lipid and enzyme metabolism remarkably decreased in starved shrimp. These attenuations could increase the susceptibility of starved shrimp to pathogens infection. In summary, this study provides novel insights into the interplay among shrimp digestion, immune activities and gut microbiota in response to starvation stress.

Abstract
Hemoglobin, the main component of haemolymph, is widely distributed in animals. Although its important oxygen transport functions has been extensively reported, studies on the immune function of hemoglobin in mollusc are few. Research on immune of hemoglobin of ark shell Scapharca broughtonii attracted more and more attention due to its ownership of erythrocyte comparing with many other shellfish. In this study, the hemoglobin cDNA of S. broughtonii was cloned by EST and RACE methods (named as SbHb). Sequence analysis revealed that the cDNA was 946 bp in length, including an open reading frame (ORF) of 459 bp which encoded a polypeptide of 152 amino acid residues, and a 5'-untranslated region (UTR) of 313 bp, a 3'-UTR of 174 bp. Sequence and homology analysis showed that the SbHb shared similarity with that of other related species. The mRNA expression profiles of SbHb in tested tissues analyzed by quantitative real-time PCR (qRT-PCR) revealed that the mRNA of SbHb could be all detected in foot, gill, mantle, adductor muscle, haemocytes and hepatopancreas, and the highest level was found in the haemocytes, which is 163.2 times higher than that in adductor muscle. Vibrio anguillarum stimulation and hypoxia treatment both had significant impact on the expression of SbHb, which showed the same trends as increasing first to the highest at 16 h after treatment and then followed by declining. Recombinant protein of SbHb (rSbHb) was successfully obtained by prokaryotic expression, and further function analysis indicated obviously that the rSbHb had very strong phenoloxidase-like activity (PO-like activity) and it could remarkably inhibit growth of gram-negative bacteria V. anguillarum. All the data suggested that the SbHb plays a significant role in the process of antibacterial and anoxia tolerance reaction in S. broughtonii, providing the evidence that SbHb is a key immune factor.

Abstract
Mucor-fermented Mao-tofu at 3-7 days was extracted using water (pH 4.5 and pH 6.5) and ethanol solutions (40 and 80%, v/v). At protein concentration of 40 μg/mL, all the extracts showed immune activities via activating macrophages, splenocytes, and natural killer cells, which enhances the secretion of interleukin (IL)-2, interferon-γ, tumor necrosis factor-α, IL-1β, IL-6, inducible nitric oxide synthase, and lysozyme, but inhibits the secretion of IL-4. All the extracts exhibited higher activities than that of soybean protein, demonstrating that Mucor-mediated fermentation enhanced the immune potentials of Mao-tofu. Fermentation time of 6 days ensured the extracts the highest activities, whereas lower activities were detected. The highest and lowest activities were detected on using a solution of water (pH 6.5) and 40% ethanol, respectively. The extract obtained using water (pH 6.5) contained more Arg and Cys with immune significance, which partially contributed to its high activities. Both fermentation times and extracting solvents were thus proved to affect the immune activities of soluble Mao-tofu extracts.

Abstract
The outbreak of Chinese Giant Salamander (Andrias davidianus, CGS) Iridovirus (CGSIV) caused massive death of CGSs. However, some CGSs with low level of CGSIV usually could survive. In our study, major capsid protein (MCP) DNA replicates of CGSIV in shedding skin were employed to assess the relative content of CGSIV in the living CGSs by qPCR. Furthermore, the examinations of autophagy and apoptosis in CGSs in vivo and in the primary renal cells in vitro were performed, respectively. The results showed that the relative contents of CGSIV in the shedding skin could reflect those in liver, spleen, and kidney of the CGSs. In these tissues of the CGSs with low-level replicates of CGSIV, there were not obviously macroscopic lesions. But the irregularly-shaped vesicles perhaps involving in autophagosome were observed by transmission electron microscopy (TEM). The LC3B protein displayed uneven distribution by Immunohistochemistry and the level mRNA of Atg5 was higher in these tissues than that in the tissues of healthy CGSs using qRT-PCR. Meanwhile, the apoptosis also appeared in these tissues by TUNEL staining and higher level mRNA of type I IFN were detected in these tissues using qRT-PCR. Further, both the expression level of LC3B II protein and Atg5 mRNA increased significantly at 2h after the virus infected the primary renal cells from the health CGSs in vitro. In addition, apoptosis and type I IFN mRNA began to increase significantly at 4h after the virus infected the renal cells. It was suggested that autophagy may be a pivotal role for survival of CGSIV in the CGSs during early infection and the rapid proliferation of CGSIV could be inhibited by innate immune response and apoptosis.

Abstract
Lactobacillus plantarum HOKKAIDO (HOKKAIDO strain) was isolated from well-pickled vegetables in Hokkaido, Japan. We report a randomized, double-blind, placebo-controlled study evaluating the effects of L. plantarum HOKKAIDO on immune function and stress markers in 171 adult subjects. Subjects were divided into three groups: the L. plantarum HOKKAIDO yogurt group, the placebo-1 group who ingested yogurt without the HOKKAIDO strain, and the placebo-2 group who ingested a yogurt-like dessert without the HOKKAIDO strain. Hematological tests and body composition measurements were performed before and after 4 and 8 weeks of blinded ingestion. Although no significant differences in natural killer cell activity were observed, it was found that neutrophil ratio significantly decreased and lymphocytes tended to increase in the HOKKAIDO strain yogurt group compared with the yogurt-like dessert group. In addition, the neutrophil-to-lymphocyte ratio, a stress marker, tended to improve in the HOKKAIDO strain yogurt group compared with the yogurt-like dessert group. These results suggest that the ingestion of HOKKAIDO strain yogurt tends to improve immune activity and decrease stress markers.

Abstract
We report on a case of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) associated with lupus erythematosus in the central nervous system (CNS). A 73-year-old woman with essential hypertension suddenly demonstrated consciousness disturbance. Upon her admission, laboratory data showed significant hyponatremia (114 mEq/L) and a lack of body fluid loss. Diminished free water excretion (urine osmolality 684 mOsm/kg) and normal urine Na excretion (FENa 1.70 %) were consistent with the diagnosis of SIADH, which was confirmed by an inappropriately high concentration of plasma antidiuretic hormone (ADH) (15.3 pg/mL at 256 mOsm/kg of plasma osmolality). The hyponatremia was corrected by a combination of oral water intake restriction and saline infusion with furosemide administration until the 20th hospital day. Simultaneously, the presence of exudative pleural effusion in both chest cavities, suggesting the existence of pleuritis, and high titer of anti-nuclear antibody (ANA, 5120×) and anti-double-strand DNA antibody (6500 IU/mL), indicated the subclinical development of systemic lupus erythematosus (SLE), although the diagnostic criteria were not satisfied at that time. On the 34th hospital day, the sudden onset of unknown consciousness disturbance confirmed the diagnosis of SLE as CNS lupus. In previous case reports on SLE and/or SIADH, a few cases in which SLE and SIADH developed concomitantly regularly showed high immunological activities, as in our case. Some common pathophysiological bases might be involved in the concomitant appearance of those disorders.
