Effects of ginger extract and/or propolis extract on immune system parameters of vaccinated broilers. Poult Sci 2023; 102:102903. [PMID: 37506621 PMCID: PMC10413198 DOI: 10.1016/j.psj.2023.102903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 06/18/2023] [Accepted: 06/24/2023] [Indexed: 07/30/2023] Open
Abstract
Newcastle disease (ND), avian influenza (AI, H5N8), and infectious bronchitis (IB) are important diseases in the poultry industry and cause significant losses. Vaccination is the most practical method for controlling infectious diseases. To reduce vaccination costs and several disorders in poultry farms, using herbal water supplements for immunomodulation with vaccination is critical to improving or preventing some conditions in the poultry industry. However, drinking water supplementation of ginger extract (GE)/propolis extract (PE) alone/in combination may increase broilers' humoral and cellular immunity due to the immunomodulatory effects of ginger and propolis. This protocol aimed to see how GE/PE alone or in combination improved the immunity, immune organ gene expression, and histology of the immune organs of broilers for 35 d after vaccination against NDV, H5N8, IBV, and IBDV. The chicks were dispensed into 5 groups according to GE and/or PE with vaccination. The control group was offered normal drinking water without any supplements or vaccinations. The GE group was supplemented with ginger extract (1 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The GE+PE group was supplemented with GE (0.5 mL/L drinking water) and PE (0.5 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The PE group was supplemented with propolis extract (1 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The fifth group was the vaccinated untreated group. This experiment showed the immunomodulatory properties of GE and/or PE against 3 common diseases, NDV, AI, and IB, in broiler chicken farms for 35 d applied to a vaccination program. Thus, ginger extract and propolis extract supplementation in drinking water increased antibody titer, INF, IL10, and IL2 and TLR3 gene expression in the bursa of Fabricius, thymus, and spleen, respectively, as well as cellular immunity as indicated by increased CD3, CD4, and CD8 in the bursa of Fabricius, thymus, and spleen, respectively, with normal lymphocytes in the medulla of the bursa, thymus, and spleen. In conclusion, propolis extracts alone or with GE improved all of the metrics mentioned above without harming the histology of the immune organs.

Optimization of Emulsification Conditions on Ethanol Extract of Taiwanese Green Propolis Using Polysorbate and Its Immunomodulatory Effects in Broilers. Animals (Basel) 2022; 12:ani12040446. [PMID: 35203153 PMCID: PMC8868552 DOI: 10.3390/ani12040446] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Revised: 02/09/2022] [Accepted: 02/09/2022] [Indexed: 02/05/2023] Open
Abstract
Simple Summary Taiwanese green propolis (TGP) ethanol extract has been shown to have a wide range of biological activities, such as antimicrobial and anti-inflammatory properties. However, extraction using ethanol limits the use of TGP as an ingredient in animal feeds. In addition, the effect of TGP ethanol extract on immunomodulation in broilers is still unclear. In order to increase the utilization of TGP ethanol extract in poultry productivity, this study aimed to establish the optimal emulsification conditions for TGP ethanol extract using polysorbate and investigate its effectiveness in improving immune response in broilers. Abstract Beeswax and resin are the main components of propolis, both of which are hydrophobic. The use of emulsifiers helps to improve the extraction of active propolis compounds and makes them more widely used. In this study, we investigated the optimal parameters for the emulsification of Taiwanese green propolis (TGP) using different polysorbates (polysorbate-20, polysorbate-60, and polysorbate-80) and evaluated the effects on the immunomodulatory response in broilers. The results showed that 4 mg/mL of TGP in combination with 2% polysorbate-60 at 60 °C for 60 min significantly decreased the undissolved particle size of ethanol extract of TGP during the emulsification. The bioactive compounds of TGP, the propolins (C, D, F, G, and H), were also detected after emulsification. Supplementation of emulsified TGP (eTGP) in the drinking water of broilers before and after vaccination significantly enhanced the antibody titer response to infectious bronchitis virus at 28 days of age. In the lipopolysaccharide-challenged model, supplementation of eTGP in the drinking water of broilers decreased pro-inflammatory gene expression and increased anti-inflammatory gene expression. These results together suggested that the polysorbate-60 could effectively emulsify the ethanol extract of TGP. Moreover, eTGP could be used as a vaccine adjuvant and an immunomodulator to improve the immune response of broilers.

Abstract
The effect of four level of Astragalus polysaccharides (APs) supplementation diets, (CD: control diet and three experiment diet (E), EA: 100 mg kg-1 APs; EB: 200 mg kg-1 APs; EC: 300 mg kg-1 APs) on growth, changes in haemato-biochemical parameters and metabolic-digestive enzymes, enhancement of antioxidant activity, innate-adaptive immune response, and cytokine gene expression were studied in catla (Catla catla) against Edwardsiella tarda. The healthy and challenged groups fed the CD displayed no mortality, while fish fed EA or EC revealed 10% mortality, but the mortality was only 5% in diet EB. Fish fed diet EB and EC revealed significantly better growth rates and high RBC count during the experimental period. Albumin and globulin levels were significant improved when fish were fed the diet EB and EC from weeks 6-8. The superoxide dismutase (SOD) was significant ameliorated by EB feeding from weeks 4-8. In contrast, serum myeloperoxidase (MPO), catalase (CAT), malondialdehyde (MDA)/lipid peroxidation (LPO), glutathione peroxidase (GPx), respiratory burst activity (RBA), bactericidal action (BCA), serum lysozyme activity (SLA), nitric oxide synthase (NOS), head kidney leukocytes response proliferation (HKLP), hemolytic action (HLA), hydrogen peroxides (H2O2), and immunoglobulin (Ig) were significantly improved from week 6-8. Groups fed the APs enriched diets had significant ameliorated interleukin (IL)-1β and interferon (IFN)-γ mRNA expression after 6 and 8 weeks of feeding. However, IL-10 and major histocompatibility complex (MHC)-1 mRNA expressions were significant enhanced in catla fed all APs diets on week 8. APs enriched diets revealed significant improved tumor necrosis factor (TNF)-α and TNF receptor-associated factor-6 (TRAF6) mRNA expression on week 4, but toll-like receptor-2 (TLR2) and TLR4 mRNA expression were significant enhanced by diet EB and EC after weeks 6 and 8. Similarly, the lysozyme (Lyz)-C and Lyz-G mRNA levels in the head kidney (HK) increased by APs feeding on weeks 6 and 8, whereas the EB diet, the expression of nucleotide binding oligomerization domain-1 (NOD1) was significantly improved on weeks 6 and 8, but NOD2 mRNA expression was only significant enhanced after 8 weeks of diet EB. By feeding healthy catla and E. tarda challenged fish fed diet EB, resulted in significantly increased growth, haemato-biochemical indices, metabolic-digestive enzymes, antioxidant activities, innate-adaptive immune responses, and cytokine gene expression mainly between 6 and 8 weeks.

Abstract
This experiment was designed to study the effects of a hydroalcoholic fruit extract from Withania coagulans (WC) and α-tocopherol acetate (α-Toc) in diets containing oxidised oil on growth performance, immune response and antioxidant indices of broiler chickens. The experiment was arranged 2 × 3 × 2 factorial comprising the oxidised oil (0% and 2% diet), WC (0, 100 and 200 mg/kg diet) and α-Toc (0 and 200 mg/kg diet). A total of 600 1-day-old male broiler chickens of the Ross strain were randomly allocated to 12 treatments with 5 replicates of 10 birds each. On day 42, one bird from each replicate was sacrified to measure the lymphoid organ weights, intestinal morphometric characteristics, and malondialdehyde content in the thigh meat. Dietary inclusion of oxidised oil significantly reduced the body weight gain in birds receiving no dietary WC (p < 0.05). In contrast, dietary supplementation of WC at 100 mg/kg diet in birds fed with the diets lacking in WC and oxidised oil resulted in significant increase in body weight gain (p < 0.05). Dietary supplementation of WC significantly increased the total anti-sheep red blood cell titre (p < 0.01). The birds fed with the dietary oxidised oil revealed significantly higher values of malondialdehyde and lower glutathione peroxidase and superoxide dismutase activities (p < 0.05). Feeding diets containing WC resulted in a significant decrease in malondialdehyde content in thigh meat while conversely, increased the glutathione peroxidase and superoxide dismutase activities (p < 0.05). The findings indicated that the dietary inclusion of WC could be recommended as a potent alternative to synthetic compounds in order to improve broilers performance, immunity and meat quality under oxidative stress conditions.

Abstract
Pigeon paramyxovirus type 1 (PPMV-1) is a globally distributed, virulent member of the avian paramyxovirus type-1. The PPMV-1-associated disease poses a great threat to the pigeon industry. The innate immune response is crucial for antiviral infections and revealing the pathogenic mechanisms of PPMV-1. In this study, we evaluated the pathogenicity of a PPMV-1 strain LHLJ/110822 in one-month-old domestic pigeons, as well as the host immune responses in PPMV-1-infected pigeons. We observed typically clinical sign in infected pigeons by 3 dpi. The morbidity rate and the mortality in pigeons inoculated with the PPMV-1 strain were up to 100% and 30%, respectively. The virus could replicate in all of the examined tissues, namely trachea, lung, liver, spleen, and bursa of Fabricius. In addition, the infected pigeons had developed anti-PPMV-1 antibodies as early as 8 dpi; and the antibody level increased over the time in this study. The expression level of toll-like receptor (TLR) 2, TLR3 TLR15, IFN-γ, and IL-6 were significantly upregulated by the PPMV-1 infection in some tissues of pigeons. By contrast, PPMV-1 infection results in downregulation of IL-18 expression in most of investigated tissues except for bursa of Fabricius in this study. The current results confirmed that this virus could replicate in pigeons and induce host immune responses, then leading to produce serum antibody titers. Meanwhile, the PPMV-1 infection induces strong innate immune responses and intense inflammatory responses at early stage in pigeon which may associate with the viral pathogenesis.

Abstract
This study assessed the effects of different selenium (Se) supplementation levels on oxidative stress, cytokines, and immunotoxicity in chicken thymus. A total of 180 laying hens (1 day old; Mianyang, China) were randomly divided into 4 groups (n = 45). The chickens were maintained either on a basic diet (control group) containing 0.2 mg/kg Se, a low-supplemented diet containing 5 mg/kg Se, a medium-supplemented diet containing 10 mg/kg Se, or a high-supplemented diet containing 15 mg/kg Se for 15, 30, and 45 days, respectively. Over the entire experimental period, serum and thymus samples were collected and used for the detection of the experimental index. The results indicated that the antioxidative enzyme activities and messenger RNA (mRNA) levels of antioxidative enzymes, IFN-γ and IL-2 in the thymus, and the content of IFN-γ and IL-2 in the serum of excessive-Se-treated chickens at all time points (except for the 5 mg/kg Se supplement group at 15 days) were significantly decreased (P < 0.05) compared to the corresponding control groups. Interestingly, a significantly increase (P < 0.05) in the content of IFN-γ was observed in the serum and thymus in the 5 mg/kg Se supplement group at 15 and 30 days compared to the corresponding control groups. In histopathological examination, the thymus tissue from excessive-Se-treated chickens revealed different degrees of cortex drop, incrassation of the medulla, and degeneration of the reticular cells. These results suggested that the excessive Se could result in a decrease in immunity, an increase in oxidative damage, and a series of clinical pathology changes, such as cortex drop, incrassation of the medulla, and degeneration of the reticular cells.

Abstract
Infection with J group avian leukosis virus (ALV-J) can result in immunosuppression and subsequently increased susceptibility to secondary infection. The innate immune system is the first line defense system in prevention of further bacterial and viral infections. Cytokines play key roles in the innate immune system. In this study, we used RT-qPCR technology to test the cytokine mRNA expression levels in various immune tissues, including the spleen, bursa of fabricius and cecal tonsil, in the days following ALV-J infection. The results indicated that in the infected group, the expression levels of interleukin-6 (IL-6), IL-18, interferon-α (IFN-α) and IFN-γ significantly increased in the spleen and reached peak levels that were thousandfolds higher than baselines at 9-12 days post-infection (d.p.i.). The levels in the bursa of fabricius slightly increased, and the levels in the cecal tonsil were not significantly altered. Moreover, the pattern of the expression of these three cytokines in the spleens of the infected group was similar to the pattern of viremia of this group. These results suggest that the spleen plays an important role in the interaction between ALV-J infection and the innate immune system. This study contributes to the understanding of innate immune responses to ALV-J infection and also elucidates the mechanisms of the pathogenicity of ALV-J in chickens.

[PMID: 24663085 PMCID: PMC3975445 DOI: 10.3390/ijms15035140] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2013] [Revised: 01/30/2014] [Accepted: 02/10/2014] [Indexed: 11/16/2022] Open
Abstract
A new water-soluble polysaccharide (longan polysaccharide 1 (LP1)) was extracted and successfully purified from Dimocarpus longan pulp via diethylaminoethyl (DEAE)-cellulose anion-exchange and Sephacryl S-300 HR gel chromatography. The chemical structure was determined using Infrared (IR), gas chromatography (GC) and nuclear magnetic resonance (NMR) analysis. The results indicated that the molecular weight of the sample was 1.1 × 10(5) Da. Monosaccharide composition analysis revealed that LP1 was composed of Glc, GalA, Ara and Gal in a molar ratio of 5.39:1.04:0.74:0.21. Structural analysis indicated that LP1 consisted of a backbone of → 4)-α-D-Glcp-(1 → 4)-α-D-GALPA-(1 → 4)-α-D-Glcp-(1 → 4)-β-D-Glcp-(1 → units with poly saccharide side chains composed of → 2)-β-D-Fruf-(1 → 2)-L-sorbose-(1 → attached to the O-6 position of the α-D-Glcp residues. In vitro experiments indicated that LP1 had significantly high antitumor activity against SKOV3 and HO8910 tumor cells, with inhibition percentages of 40% and 50%, respectively. In addition, LP1 significantly stimulated the production of the cytokine interferon-γ (IFN-γ), increased the activity of murine macrophages and enhanced B- and T-lymphocyte proliferation. The results of this study demonstrate that LP1 has potential applications as a natural antitumor agent with immunomodulatory activity.

Abstract
The moss Physcomitrella patens has a number of advantages for the production of biopharmaceuticals, including: i) availability of standardized conditions for cultivation in bioreactors; ii) not being part of the food chain; iii) high biosafety; iv) availability of highly efficient transformation methods; v) a haploid, fully sequenced genome providing genetic stability and uniform expression; vi) efficient gene targeting at the nuclear level allows for the generation of mutants with specific post-translational modifications (e.g., glycosylation patterns); and vii) oral formulations are a viable approach as no toxic effects are attributed to ingestion of this moss. In the light of this panorama, this opinion paper analyzes the possibilities of using P. patens for the production of oral vaccines and presents some specific cases where its use may represent significant progress in the field of plant-based vaccine development. The advantages represented by putative adjuvant effects of endogenous secondary metabolites and producing specific glycosylation patterns are highlighted.

Abstract
This study investigated the humoral immunization of Astragalus polysaccharide (APS) against H9N2 avian influenza virus (H9N2 AIV) infection in chickens.The effects of APS treatment on H9N2 infection was evaluated by an MTT [3(4, 5-dimethylthiazol-2-yl)-2, 3-diphenyl tetrazolium bromide] assay and analysis of MHC and cytokine mRNA expression. The effect on lymphocyte and serum antibody titers in vivo was also investigated. IL-4, IL-6, IL-10, LITAF, IL-12 and antibody titers to H9N2 AIV were enhanced in the first week after APS treatment. The results indicated that APS treatment reduces H9N2 AIV replication and promotes early humoral immune responses in young chickens.

Abstract
Three adjuvants, namely, Taishan Pinus massoniana pollen polysaccharide (TPPPS), white mineral oil (WO) and propolis (PP), were added to the outer membrane protein (OMP) of Proteus mirabilis (P. mirabilis) and their effects were compared. Three hundred 1-day-old chicks were randomly divided into five groups (I-V), with 60 chicks per group, and injected subcutaneously with WO-OMP vaccine (I), PP-OMP vaccine (II), TPPPS-OMP vaccine (III), OMP-only vaccine (IV) and physiological saline (V) at 3, 7 and 12 days old. On days 3, 7, 14, 21, 28, 35, 42 and 49 after the first vaccination, the antibody titers, interleukin-2 levels (IL-2) and T-lymphocyte proliferation rates in the peripheral blood as well as the secreting-type IgA levels (SIgA) in the duodenum were measured. On day 7 after the third vaccination, the chicks were challenged with P. mirabilis strain Q1 and the protective effects of each group were observed. The highest protective rate was observed in group III. Moreover, the antibody titers as well as IL-2, SIgA and T-lymphocyte proliferation rates in this group significantly increased and were significantly higher than those in the other groups at most time points. The results indicate that TPPPS could significantly enhance the effects of the subunit vaccine of P. mirabilis; induced stronger humoral, cellular and mucosal immunity as compared with WO and PP; and should be developed as a vaccine adjuvant.

Abstract
The preparation conditions of epimedium polysaccharide-propolis flavone liposome (EPL) were optimized by response surface methodology taking entrapment rates of epimedium polysaccharide and propolis flavone as indexes. The immunoenhancement of EPL prepared with optimized condition was determined taking epimedium polysaccharide-propolis flavone suspension (EPS) and epimedium polysaccharide-propolis flavone watery solution (EPW) as control. The results showed that the optimized preparation condition was as follows: the ratio of drug to lipid was 14:1, the ratio of soybean phospholipid to cholesterol was 6:1, and the ultrasonic time was 19 min. EPL could significantly promote the proliferation of T and B lymphocytes singly or synergistically with PHA or LPS, mRNA expression of IL-2 and IL-6 and secretion of IgG and IgM as compared with EPS and EPW. These results indicated that liposome could significantly improve the immunoenhancement of epimedium polysaccharide-propolis flavone immunopotentiator (EPI) and would be as the suitable dosage form of EPI.

Abstract
BACKGROUND Astragalus polysaccharide (APS) has been used as an immunomodulator that can enhance immune responses, whereas the immunomodulatory effects of APS on porcine peripheral blood mononuclear cells (PBMCs) exposed to porcine reproductive and respiratory syndrome virus (PRRSV) and classical swine fever virus (CSFV) have not been investigated. METHODOLOGY/PRINCIPAL FINDINGS Porcine PBMCs were cultured in complete RPMI media in the presence of the R98-strain of PRRSV (5×10(4) TCID(50)/ml) or C-strain of CSFV (10(3) TCID(50)/ml) with or without APS. The expression of mRNA for CD28, cytotoxic T-lymphocyte antigen 4 (CTLA-4), transforming growth factor-β (TGF-β), interleukin 2 (IL-2) and IL-10 was assayed by TaqMan real-time RT-PCR. The expression of mRNA for CD28 and CTLA-4 increased at 24 h after stimulation of PBMCs with CSFV and the increased production of CTLA-4 was confirmed by western blot analysis, whereas the increases were inhibited by the addition of APS. In addition, APS alone upregulated IL-2 and TGF-β mRNA expression in PBMCs and the addition of APS had the capacity to prevent a further increase in IL-2 mRNA expression in PBMCs during CSFV or PRRSV infection, but had no effect on TGF-β mRNA expression. The production of tumor necrosis factor-alpha (TNF-α) increased at 12 h after stimulation with PRRSV or CSFV, but not with PRRSV plus APS or CSFV plus APS, whereas the addition of APS to PBMCs infected with PRRSV or CSFV promoted IL-10 mRNA expression. CONCLUSIONS We suggested that APS had immunomodulatory effects on cells exposed to PRRSV or CSFV. It might be that APS via different mechanisms affects the activities of immune cells during either PRRSV or CSFV infection. This possibility warrants further studies to evaluate whether APS would be an effective adjuvant in vaccines against PRRSV or CSFV.

Abstract
The aim of this strategy was to investigate whether the adjuvant activity of epimedium polysaccharide (EPS) could be further enhanced after encapsulated with liposome. In preparation of EPS liposome (EPSL) test, an orthogonal L(9) (3(4)) test design was used to optimize the preparation condition of EPSL. In adjuvant activity test, 350 14-day-old chickens were randomly assigned to 7 groups and vaccinated with Newcastle disease (ND) vaccine. Simultaneously, the chickens in experimental groups were injected with EPSL at three doses, EPS and blank liposome, respectively. The activity of lymphocytes proliferation, titer of serum antibody and concentrations of cytokines were determined. Results showed that the optimal preparation condition of EPSL was that ratio of drug to lipid, ratio of soybean phospholipid to cholesterol, ultrasonic time, and water bath temperature were 1:30, 4:1, 10 min and 40°C, respectively. EPSL could significantly enhance the immune response of ND vaccine and promote cytokines secretion, and its high dose possessed the best efficacy. These findings indicated that liposome encapsulation could significantly improve the adjuvant activity of EPS.

Abstract
Three preparations of epimedium polysaccharide-propolis flavone immunopotentiator (EPI), EPI liposome, EPI suspension and EPI watery solution were prepared. In immune response test, their adjuvanticities were compared in 14-day-old chickens vaccinated with Newcastle disease (ND) vaccine. In immune protection test, the effects of the three preparations on Newcastle disease virus (NDV) infection were compared in chickens vaccinated with ND vaccine then challenged with NDV. The results displayed that EPI liposome could enhance the antibody titer, T lymphocyte proliferation and the concentrations of interferon-γ and interleukin-6, when compared with the other two preparations. In EPI liposome group, the antibody titers, lymphocyte proliferation and protective rate were the highest, while the mortality and morbidity were the lowest, in comparison with the other groups. These results indicated that liposome could enhance the immune effect of EPI on ND vaccine and would be expected as the suitable dosage form of this immunopotentiator.

Abstract
Propolis is a honeybee product showing several biological properties that enhance the immune response, depending on the concentration and intake period. Because propolis possesses an immunomodulatory action on mammals, the objective of our study was to investigate the effects of propolis on the humoral immune response of laying hens by evaluating antibody production. Laying hens (ISA Brown) were divided into 5 groups with 7 birds each. Group 1 was a nonimmunized control, whereas birds in group 2 were immunized intravenously with SRBC, and those in groups 3, 4, and 5 were treated intraperitoneally with propolis (2, 10, and 50 mg/kg, respectively) on 3 consecutive days and then inoculated intravenously with SRBC. Hematological and serological analyses were carried out on d 0, 3, and 38. Natural and specific antibody levels were determined by hemagglutination with rabbit red blood cells and SRBC, respectively. Propolis-treated birds (50 mg/kg) showed a significant decline in heterophils and in the heterophil:lymphocyte ratio. After SRBC immunization, significant increases in levels of IgG were observed in groups 4 and 5. Furthermore, higher levels of natural antibodies were observed in propolis-treated laying hens. The administration of propolis to laying hens increased the production of IgG specific to SRBC and natural antibodies, and could be used to increase antigen-specific antibody responses to vaccines.

Abstract
Newcastle disease virus (NDV) is an important pathogen hazardous to poultry industry, and the pathogenicity of NDV strains varies with different virulence. Peripheral blood serves as an important producer and carrier of viruses and cytokines in NDV infection. In order to explore the difference of cytokine expression in the peripheral blood between velogenic strain and lentogenic strain infection, NDV virulent strain F48E9 and vaccine strain Lasota were used to infect specific-pathogen-free (SPF) chickens separately, and peripheral blood was collected on 0, 3, 7, 10, 14, and 21 days post-infection (d.p.i.). Real-time PCR was then used to detect the expression of six kinds of immune-related cytokine genes. For the F48E9 group, a sharp increase of the expression of interferon-alpha (IFN-α), interferon-gamma (IFN-γ), interleukin-16 and IL-18 was observed on 3 d.p.i. before the NDV blood peak (7 d.p.i.), followed by a rapid decline to the level lower than that of control group, then the expression of IFN-α increased slowly and reached or exceeded the level of control group in the later phase of the infection, while the expression of IFN-γ, IL-16, and IL-18 fluctuated at the level of control group for the rest of study period. The increase of IL-2 expression was not obvious, and no increase of IL-15 expression was noted. For the Lasota (vaccine) group, the picture was quite different, a sharp increase of IFN-γ (but not IFN-α), IL-2 was observed on 7 d.p.i. before the NDV blood peak (10 d.p.i.). On the contrary, there was no dramatic increase of IL-16 and IL-18. Interestingly, in contrast to the F48E9 group, there was an increase of IL-15 on day 10 d.p.i., but it remained modest. There was also an increase of IFN-α on day 21 d.p.i. Our results revealed that infection with NDV strains of different virulence was associated with distinct cytokine expression patterns in peripheral blood, modulation of cytokine responses may play a key role in mediation of NDV pathogenesis.

Abstract
The acquired immunity is underdeveloped at 3-4 weeks of age when piglets are usually weaned on commercial farms, and weaning is associated with compromised immunity. Dietary supplementation with immunomodulatory phytochemicals may enhance immune responses in the weaned piglets. This study is conducted to investigate the effects of dietary supplemental achyranthes bidentata polysaccharide (ABP) on proliferation activity of lymphocytes, and production of antibodies, complements and cytokines in weaned piglets. Results showed that lymphocyte proliferation activity in piglets fed diets supplementing with 1000 and 1500 mg/kg ABP increased (P < 0.05) on days 14 and 28 compared with the non-additive piglets, as well as serum contents of IgG, IgA, IgM, C(3), C(4), IL (interleukin)-2 and IFN (interferon)-gamma. The ABP had dose-dependent immunomodulatory activity and the dose of 1500 mg/kg presented the strongest stimulating activity in vivo. In addition, the ABP increased (P < 0.05) the proliferation activity and production of IL-2 and IFN-gamma of cultured lymphocytes in dose- or time-dependent manner. The proliferation activity of peripheral T cells and splenic lymphocytes in 400 microg/ml of ABP group arrived at their peak values, as well as the production of IL-2 and IFN-gamma at 72 and 12 h after the treatment, respectively. Collectively, these findings suggested that dietary supplementation with ABP to weaned piglets enhances cellular and humoral immune responses, and ABP addition to culture medium also increases the proliferation activity and cytokine production of lymphocytes cultured in vitro, which indicate that dietary supplementation with the herbal polysaccharide may offer an effective alternative to antibiotics for weaned piglets.

Abstract
In order to validate the immune-enhancement efficacy of compound Chinese herbal medicinal ingredients (cCHMIs), made with astragalus polysaccharide (APS), epimedium polysaccharide (EPS), propolis flavone (PF) and ginsenosides (GS), as immune potentiator or vaccine adjuvants for rabbits, the effects of two cCHMIs on rabbit lymphocyte proliferation and IFN-gamma and IL-10 mRNA expression of T lymphocyte in vitro were determined. At the same time, two cCHMIs were injected into 35-day-old rabbits after mixed with rabbit hemorrhagic disease (RHD) vaccine taking aluminum adjuvant and phosphate-buffered saline (PBS) as controls. On days 7, 14, 21, 35 and 49 after the vaccination, the dynamic changes of peripheral lymphocyte proliferation and serum antibody titers of the rabbits were analyzed. On day 63, all rabbits were challenged with RHD virus. The results showed that the two cCHMIs could significantly promote rabbit lymphocyte proliferation and IFN-gamma and IL-10 mRNA expression of T lymphocyte in vitro. In vivo, two cCHMIs could significantly enhance serum antibody titers and lymphocyte proliferation. Their adjuvanticity was slightly superior to aluminum adjuvant. All the rabbits vaccinated with the cCHMIs adjuvant vaccine were protected. These findings confirmed that two cCHMIs possessed better immune-enhancement efficacy and would be used as effective immune adjuvant of RHD vaccine.
