Abstract
The urgent task of creating new, enhanced adjuvants is closely related to our comprehension of their mechanisms of action. A few adjuvants have shown sufficient efficacy and low toxicity to be allowed for use in human vaccines, despite the fact that they have a long history and an important function. Adjuvants have long been used without a clear understanding of how precisely they augment the immune response. The rational production of stronger and safer adjuvants has been impeded by this lack of information, which necessitates more mechanistic research to support the development of vaccines. Carbohydrate structures-polygalactans, fructans, β-D-glucans, α-D-glucans, D-galactose, and D-glucose-are desirable candidates for the creation of vaccine adjuvants and immunomodulators because they serve important functions in nature and are often biocompatible, safe, and well tolerated. In this review, we have discussed recent advances in microbial-derived carbohydrate-based adjuvants, their immunostimulatory activity, and the implications of this for vaccine development, along with the critical view on the microbial sources, chemical composition, and biosynthetic pathways.

Abstract
Piglets are susceptible to infections in early life and around weaning due to rapid environmental and dietary changes. A compelling target to improve pig health in early life is diet, as it constitutes a pivotal determinant of gut microbial colonization and maturation of the host’s immune system. In the present study, we investigated how supplementation of yeast-derived β-glucans affects the gut microbiota and immune function pre- and post-weaning, and how these complex systems develop over time. From day two after birth until two weeks after weaning, piglets received yeast-derived β-glucans or a control treatment orally and were subsequently vaccinated against Salmonella Typhimurium. Faeces, digesta, blood, and tissue samples were collected to study gut microbiota composition and immune function. Overall, yeast-derived β-glucans did not affect the vaccination response, and only modest effects on faecal microbiota composition and immune parameters were observed, primarily before weaning. This study demonstrates that the pre-weaning period offers a ‘window of opportunity’ to alter the gut microbiota and immune system through diet. However, the observed changes were modest, and any long-lasting effects of yeast-derived β-glucans remain to be elucidated.

Abstract
β-glucans, a group of polysaccharides exist in many organism species such as mushrooms, yeasts, oats, barley, seaweed, but not mammalians, have a variety of biological activities and applications in drugs and other healthcare products. In recent years, β-glucans have been studied as adjuvants in anti-infection vaccines as well as immunomodulators in anti-cancer immunotherapy. β-glucans can regulate immune responses when administered alone and can connect innate and adaptive immunity to improve immunogenicity of vaccines. When β-glucans act as immunostimulants or adjuvants, a set of receptors have been revealed to recognize β-glucans, including dectin-1, complement receptor 3 (CR3), CD5, lactosylceramide, and so on. Therefore, this review is mainly focused on the application of β-glucans as immune adjuvants, the receptors of β-glucans, as well as their structure and activity relationship which will benefit future research of β-glucans.

Intranasal Immunization with Influenza Virus-Like Particles Containing Membrane-Anchored Cholera Toxin B or Ricin Toxin B Enhances Adaptive Immune Responses and Protection against an Antigenically Distinct Virus. Viruses 2016; 8:115. [PMID: 27110810 PMCID: PMC4848608 DOI: 10.3390/v8040115] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2016] [Revised: 03/14/2016] [Accepted: 04/15/2016] [Indexed: 11/16/2022] Open
Abstract
Vaccination is the most effective means to prevent influenza virus infection, although current approaches are associated with suboptimal efficacy. Here, we generated virus-like particles (VLPs) composed of the hemagglutinin (HA), neuraminidase (NA) and matrix protein (M1) of A/Changchun/01/2009 (H1N1) with or without either membrane-anchored cholera toxin B (CTB) or ricin toxin B (RTB) as molecular adjuvants. The intranasal immunization of mice with VLPs containing membrane-anchored CTB or RTB elicited stronger humoral and cellular immune responses when compared to mice immunized with VLPs alone. Administration of VLPs containing CTB or RTB significantly enhanced virus-specific systemic and mucosal antibody responses, hemagglutination inhibiting antibody titers, virus neutralizing antibody titers, and the frequency of virus-specific IFN-γ and IL-4 secreting splenocytes. VLPs with and without CTB or RTB conferred complete protection against lethal challenge with a mouse-adapted homologous virus. When challenged with an antigenically distinct H1N1 virus, all mice immunized with VLPs containing CTB or RTB survived whereas mice immunized with VLPs alone showed only partial protection (80% survival). Our results suggest that membrane-anchored CTB and RTB possess strong adjuvant properties when incorporated into an intranasally-delivered influenza VLP vaccine. Chimeric influenza VLPs containing CTB or RTB may represent promising vaccine candidates for improved immunological protection against homologous and antigenically distinct influenza viruses.

Abstract
DNA vaccine represents a powerful approach for prevention of avian H5N1 influenza infection. Yet, DNA vaccine-induced immune responses might be limited by the short duration of antigen expression. As a strategy to enhance adaptive immune responses elicited by a hemagglutinin 5 (H5) DNA vaccine, we explored the effect of co-administration of a DNA encoding X-linked inhibitor of apoptosis protein (XIAP) as a modulator of apoptosis and a stimulator of inflammatory signaling. In cultured cells as early as 24 hours (h), we found that the DNA vaccine encoded H5 antigen was a potent stimulator of apoptosis, and the H5 pro-apoptotic activity was significantly suppressed by the co-expression of full-length XIAP or mutant XIAP (ΔRING). However, full-length XIAP showed a higher potency than mutant XIAP (ΔRING) in the inhibition of H5-induced apoptosis. We also compared the immunizing ability of transmembrane and secretory forms of H5. Mice vaccinated (twice with 3-week intervals) with the secretory form of H5 showed higher hemagglutination inhibition (HI) antibody titers than mice vaccinated with the transmembrane form of H5. Furthermore, co-administration of XIAP with the secretory form of H5 resulted into a stronger antibody response than the transmembrane form of H5. Our findings suggest that in the design of DNA vaccines for a given pro-apoptotic antigen, using an anti-apoptotic molecular adjuvant and the secretory form of antigen may be a greater stimulus to induce immune responses.

Abstract
Influenza virus-like particles (VLPs) represent promising alternative vaccines. However, it is necessary to demonstrate that influenza VLPs confer cross-protection against antigenically distinct viruses. In this study, a VLP vaccine comprising hemagglutinin (HA) and M1 from the A/California/04/2009 (H1N1) were used and its ability to induce cross-protective efficacy against heterologous viruses A/PR/8/34 (H1N1) and A/New Caledonia/20/99 (H1N1) in mice was assessed. Vaccination with 2009 H1 VLPs induced significantly higher levels of IgG cross-reactive with these heterologous viruses after the second boost compared to after the prime or first boost. Lung virus titers also decreased significantly and the lung cross-reactive IgG response after lethal virus challenge was significantly greater in immunized mice compared to naïve mice. Vaccinated mice showed 100% protection against A/PR/8/34 and A/Caledonia/20/99 viruses with only moderate body weight loss and induction of cross-reactive recall, IgG antibody-secreting cell responses. The variations in HA amino acid sequences and antigenic sites were determined and correlated with induction of cross-protective immunity. These results indicate that VLPs can be used as an effective vaccine that confers cross-protection against antigenically distinct viruses.

Abstract
Identification and characterization of compounds that enhance the growth, development, and health of infants who are not breastfed continues to be a goal for nutritional science. This study explored the effects of one dietary component, (1,3/1,6)-β-D-glucan (Wellmune WGP), on lung immune development in the neonatal piglet. The hypothesis was that supplementation with WGP, a pathogen-associated molecular pattern, would enhance pathogen-responsive elements of the immune system, for instance, by increasing the size of the cytotoxic T-cell population or the expression of inflammatory cytokines. Piglets were fed a control formula or formula plus WGP at 1.8, 18, or 90 mg/kg body weight per day. Serum, thoracic lymph nodes (TLNs), mediastinal lymph nodes, and lung were collected at days 7 or 21. Immune parameters including tissue messenger RNA (mRNA) expression and T-cell phenotypes were analyzed. Normal developmental changes were observed, with a decrease in T-helper cells and an increase in cytotoxic T cells in both TLN and mediastinal lymph node, but there was no effect of WGP. Dietary WGP reduced the mRNA expression of transforming growth factor (TGF) β2 and tended to reduce the mRNA expression of TGF-β1 in lung tissue. With the exception of reducing TGF-β mRNA in the lung and tending to decrease the ratio of T helper to cytotoxic T cell in the TLN, dietary WGP did not affect lung-associated adaptive immunity in piglets.

Abstract
Infants are susceptible to infections in early life and must rely on their innate immune system for protection. β-Glucans potentiate immune responses. Therefore, we evaluated the influence of purified yeast (1,3/1,6)-β-d-glucan (Wellmune WGP, here referred to as WGP) on the development of the gastrointestinal tract and the intestinal and systemic immune systems in neonatal piglets. Piglets were fed formula containing 0 (control), 1.8, 18, or 90 mg WGP/kg body weight (BW) and were vaccinated against human influenza. Piglets were euthanized at 7 or 21 days of age. Piglet weight and small intestinal length and weight were unaffected by dietary WGP. In addition, WGP did not affect ileal crypt depth, villus height, or ascending colon cuff depth. Immune parameters not affected by WGP supplementation included T cell phenotypes, cytokine gene expression, and cell proliferation. However, vaccination and developmental effects were seen. Overall, the doses of 1.8, 18, and 90 mg/kg BW of dietary WGP had no effect on intestinal or immune development and did not improve the antibody response to vaccination in neonatal piglets.
