Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.

Activity in saline of phthalylated or succinylated derivatives of mycobacterial water-soluble adjuvant. (1/6132)

A water-soluble fraction (WSA) of the cell wall can substitute for mycobacterial cells in Freund complete adjuvant. However, when WSA is administered in saline instead of in a water-in-oil emulsion, its adjuvant activity is very weak, and under certain experimental conditions it can even inhibit the humoral immune response. The data reported in the present study show that after treatment by phthalic or succinic anhydride the adjuvant activity of WSA was markedly changed, since high levels of circulating antibodies were produced when these derivatives were administered with an antigen in an aqueous medium. Moreover, the antigenic determinants of WSA were modified and acylated WSA had no tuberculin-like activity.  (+info)

Systemic administration of rIL-12 synergistically enhances the therapeutic effect of a TNF gene-transduced cancer vaccine. (2/6132)

Interleukin-12 (IL-12) is a potent antitumor cytokine, which induces and enhances the activity of natural killer (NK) cells, lymphokine activated killer (LAK) cells and cytotoxic T lymphocytes (CTL). IL-12 also stimulates IFN-gamma production from both T cells and NK cells. In this study, we transfected methylcholanthrene-induced fibrosarcoma (MCA-D) with TNF gene and investigated the therapeutic effect of TNF gene-transduced cancer vaccine and whether the vaccination effect is enhanced by systemic administration of recombinant IL-12 (rIL-12), in a murine model. TNF gene-transduced cancer vaccine or systemic administration of rIL-12 showed slight or moderate inhibition of pre-established tumor. However, simultaneous application of the vaccine and rIL-12 resulted in complete eradication. The cytotoxicity of CTL against parental tumor cells was enhanced with the combination of the vaccine and rIL-12, and IFN-gamma production from spleen cells also increased synergistically. Our findings show that synergistic enhancement of CTL activity and IFN-gamma production could play an important role in the antitumor effect of combination therapy using TNF gene-transduced cancer vaccine and rIL-12.  (+info)

Transcutaneous immunization with bacterial ADP-ribosylating exotoxins as antigens and adjuvants. (3/6132)

Transcutaneous immunization (TCI) is a new technique that uses the application of vaccine antigens in a solution on the skin to induce potent antibody responses without systemic or local toxicity. We have previously shown that cholera toxin (CT), a potent adjuvant for oral and nasal immunization, can induce both serum and mucosal immunoglobulin G (IgG) and IgA and protect against toxin-mediated mucosal disease when administered by the transcutaneous route. Additionally, CT acts as an adjuvant for coadministered antigens such as tetanus and diphtheria toxoids when applied to the skin. CT, a member of the bacterial ADP-ribosylating exotoxin (bARE) family, is most potent as an adjuvant when the A-B subunits are present and functional. We now show that TCI induces secondary antibody responses to coadministered antigens as well as to CT in response to boosting immunizations. IgG antibodies to coadministered antigens were also found in the stools and lung washes of immunized mice, suggesting that TCI may target mucosal pathogens. Mice immunized by the transcutaneous route with tetanus fragment C and CT developed anti-tetanus toxoid antibodies and were protected against systemic tetanus toxin challenge. We also show that bAREs, similarly organized as A-B subunits, as well as the B subunit of CT alone, induced antibody responses to themselves when given via TCI. Thus, TCI appears to induce potent, protective immune responses to both systemic and mucosal challenge and offers significant potential practical advantages for vaccine delivery.  (+info)

Zonula occludens toxin is a powerful mucosal adjuvant for intranasally delivered antigens. (4/6132)

Zonula occludens toxin (Zot) is produced by toxigenic strains of Vibrio cholerae and has the ability to reversibly alter intestinal epithelial tight junctions, allowing the passage of macromolecules through the mucosal barrier. In the present study, we investigated whether Zot could be exploited to deliver soluble antigens through the nasal mucosa for the induction of antigen-specific systemic and mucosal immune responses. Intranasal immunization of mice with ovalbumin (Ova) and recombinant Zot, either fused to the maltose-binding protein (MBP-Zot) or with a hexahistidine tag (His-Zot), induced anti-Ova serum immunoglobulin G (IgG) titers that were approximately 40-fold higher than those induced by immunization with antigen alone. Interestingly, Zot also stimulated high anti-Ova IgA titers in serum, as well as in vaginal and intestinal secretions. A comparison with Escherichia coli heat-labile enterotoxin (LT) revealed that the adjuvant activity of Zot was only sevenfold lower than that of LT. Moreover, Zot and LT induced similar patterns of Ova-specific IgG subclasses. The subtypes IgG1, IgG2a, and IgG2b were all stimulated, with a predominance of IgG1 and IgG2b. In conclusion, our results highlight Zot as a novel potent mucosal adjuvant of microbial origin.  (+info)

Emergent immunoregulatory properties of combined glucocorticoid and anti-glucocorticoid steroids in a model of tuberculosis. (5/6132)

In Balb/c mice with pulmonary tuberculosis, there is a switch from a protective Th1-dominated cytokine profile to a non-protective profile with a Th2 component. This switch occurs while the adrenals are undergoing marked hyperplasia. Treatment with the anti-glucocorticoid hormones dehydroepiandrosterone or 3 beta, 17 beta-androstenediol, during the period of adrenal hyperplasia, maintains Th1 dominance and is protective. We investigated the effects of these hormones as therapeutic agents by administering them from day 60, when the switch to the non-protective cytokine profile was already well established. Given at this time (day 60), doses that were protective when given early (from day 0) were rapidly fatal. A physiological dose of the glucocorticoid corticosterone was also rapidly fatal. However when the corticosterone and the anti-glucocorticoid (AED or DHEA) were co-administered, there was protection, with restoration of a Th1-dominated cytokine profile, enhanced DTH responses, and enhanced expression of IL-1 alpha and TNF alpha. Therefore this combination of steroids has an emergent property that is quite unlike that of either type of steroid given alone. It may be possible to exploit the ant-inflammatory properties of glucocorticoids while preserving a Th1 bias, by combining glucocorticoids with DHEA or suitable metabolites.  (+info)

N,N'-Diacetyl-L-cystine-the disulfide dimer of N-acetylcysteine-is a potent modulator of contact sensitivity/delayed type hypersensitivity reactions in rodents. (6/6132)

Oral N-acetyl-L-cysteine (NAC) is used clinically for treatment of chronic obstructive pulmonary disease. NAC is easily oxidized to its disulfide. We show here that N,N'-diacetyl-L-cystine (DiNAC) is a potent modulator of contact sensitivity (CS)/delayed type hypersensitivity (DTH) reactions in rodents. Oral treatment of BALB/c mice with 0.003 to 30 micromol/kg DiNAC leads to enhancement of a CS reaction to oxazolone; DiNAC is 100 to 1000 times more potent than NAC in this respect, indicating that it does not act as a prodrug of NAC. Structure-activity studies suggest that a stereochemically-defined disulfide element is needed for activity. The DiNAC-induced enhancement of the CS reaction is counteracted by simultaneous NAC-treatment; in contrast, the CS reaction is even more enhanced in animals treated with DiNAC together with the glutathione-depleting agent buthionine sulfoximine. These data suggest that DiNAC acts via redox processes. Immunohistochemically, ear specimens from oxazolone-sensitized and -challenged BALB/c mice treated with DiNAC display increased numbers of CD8(+) cells. DiNAC treatment augments the CS reaction also when fluorescein isothiocyanate is used as a sensitizer in BALB/c mice; this is a purported TH2 type of response. However, when dinitrofluorobenzene is used as a sensitizer, inducing a purported TH1 type of response, DiNAC treatment reduces the reaction. Treatment with DiNAC also reduces a DTH footpad-swelling reaction to methylated BSA. Collectively, these data indicate that DiNAC in vivo acts as a potent and effective immunomodulator that can either enhance or reduce the CS or DTH response depending on the experimental conditions.  (+info)

Issues in the treatment of active tuberculosis in human immunodeficiency virus-infected patients. (7/6132)

Most HIV-infected patients with tuberculosis can be treated satisfactorily with standard regimens with expectations of good results. Treatment of tuberculosis in these patients has been complicated by the introduction of HAART, which relies on drugs that interfere with the most potent class of antituberculous medications. Rifampin-free regimens or regimens that employ rifabutin may be acceptable strategies for patients who are receiving protease inhibitors, although these regimens have not been rigorously evaluated in patients with AIDS. At present, there is good reason to believe that a 6-month course of a rifabutin-containing regimen or a 9-12-month course of a regimen of streptomycin, isoniazid, and pyrazinamide should be adequate therapy for most patients with drug-susceptible disease. As the treatment of HIV infection with antiretroviral agents evolves, the treatment of tuberculosis in patients with AIDS is likely to evolve as well. This will require careful coordination of antituberculosis and antiretroviral therapies.  (+info)

Soluble HLA class I, HLA class II, and Fas ligand in blood components: a possible key to explain the immunomodulatory effects of allogeneic blood transfusions. (8/6132)

The immunomodulatory effect of allogeneic blood transfusions (ABT) has been known for many years. However, a complete understanding of the effects of ABT on the recipient's immune system has remained elusive. Soluble HLA class I (sHLA-I), HLA class II (sHLA-II), and Fas ligand (sFasL) molecules may play immunoregulatory roles. We determined by double-determinant immunoenzymatic assay (DDIA) sHLA-I, sHLA-II, and sFasL concentrations in different blood components. sHLA-I and sFasL levels in red blood cells (RBCs) stored for up to 30 days and in random-donor platelets are significantly (P <.001) higher than in other blood components and their amount is proportionate to the number of residual donor leukocytes and to the length of storage. Blood components with high sHLA-I and sFasL levels play immunoregulatory roles in vitro as in allogeneic mixed lymphocyte responses (MLR) and antigen-specific cytotoxic T-cell (CTL) activity, and induce apoptosis in Fas-positive cells. These data suggest that soluble molecules in blood components are functional. If these results are paralleled in vivo, they should be taken into account in transfusion practice. Blood components that can cause immunosuppression should be chosen to induce transplantation tolerance, whereas blood components that lack immunosuppressive effects should be preferred to reduce the risk of postoperative complications and cancer recurrence.  (+info)

Traditionally immunostimulants have been believed to worsen autoimmune disease, to the point that some immunostimulants have originally been classified as immunosuppressants because they were found to improve autoimmune disease. But in practice it does not seem to work like that.. If the theory that autoimmune disease is in fact a type of an immune deficiency - or that there are components of immune deficiency, as the immune system is highly complex and not necessarily easy to define as overactive or underactive - is correct, immunostimulants would be the rational choice of treatment.. Immunostimulants are not completely without risks or side effects, but some of them can get quite close. They do not increase the risk of infections and cancer - and may even reduce the risk.. The most conventionally accepted immunostimulant therapy for autoimmune diseases is intravenous immunoglobulin (also known as IVIG and gammaglobulin), a blood product that contains antibodies from thousands of donors. It ...
In immunology, an adjuvant is a component that potentiates the immune responses to an antigen and/or modulates it towards the desired immune responses. The word adjuvant comes from the Latin word adiuvare, meaning to help or aid. An immunologic adjuvant is defined as any substance that acts to accelerate, prolong, or enhance antigen-specific immune responses when used in combination with specific vaccine antigens. A magazine article about vaccine adjuvants in 2007 was headlined Deciphering Immunologys Dirty Secret to refer to the early days of vaccine manufacture, when significant variations in the effectiveness of different batches of the same vaccine were observed, correctly assumed to be due to contamination of the reaction vessels. However, it was soon found that more scrupulous attention to cleanliness actually seemed to reduce the effectiveness of the vaccines, and that the contaminants - dirt - actually enhanced the immune response. There are many known adjuvants in widespread ...

Detailed Description of the Invention The present invention relates to the use of the A fraction of Quil A together with at least one other adjuvant for the production of an adjuvant composition having a synergistic effect that improves the level and quality of immunomodulatory activity. . In particular, regarding the use of the A fraction of Quil A with one or more other adjuvants, where the A fraction at a dose that is well tolerated at a low dose is itself co-administered as a prophylactic use Or synergistically improve the immune enhancing effect of an adjuvant that is too toxic for clinical use. That is, a co-administered, well-tolerated low dose (in other words, less than optimal dose) adjuvant is effective and suitable for use. Therefore, other adjuvants are preferred that are substantially toxic and whose dose is reduced to an extent acceptable for prophylactic and clinical use, but are weak and as such are effective in providing a level of immune response. Also preferred are adjuvants ...
Recent years have seen great interest in vaccine development. This has resulted in part from the clinical need for better ways to prevent infection, but there has also been much interest in the development of therapeutic vaccines for tumors and for the treatment of HIV infections (1, 2). New approaches to the production of vaccines include the use of synthetic peptides, DNA, RNA, and protein subunits. These approaches offer a number of advantages, including increased specificity and reduced toxicity (1, 2). However, many are poorly immunogenic when administered alone (1, 2, 3). Currently used adjuvants include mineral salts, immunostimulatory cytokines, lipid particles, microparticulates, and so-called mucosal adjuvants (1, 2, 3). Although the mechanisms of action for some of these, such as immunostimulatory cytokines, may be inferred from what is known of their physiologic activities, the mechanisms of action of many of these are poorly understood. Preclinical and clinical trials have been ...
Pattern recognition receptors, including the Toll-like receptors (TLRs), are important in the induction and activation of two critical arms of the host defence to pathogens and microorganisms; the rapid innate immune response (as characterised by the production of Th1 promoting cytokines and type 1 interferons) and the adaptive immune response. Through this activation, ligands and agonists of TLRs can enhance immunotherapeutic efficacy. Resiquimod is a small (water-soluble) agonist of the endosome-located Toll-like receptors 7 and 8 (TLR7/8). However due to its molecular attributes it rapidly distributes throughout the body after injection. To circumvent this, these TLR agonists can be incorporated within delivery systems, such as liposomes, to promote the co-delivery of both antigen and agonists to antigen presenting cells. In this present study, resiquimod has been chemically conjugated to a lipid to form a lipid-TLR7/8 agonist conjugate which can be incorporated within immunogenic cationic ...
Thirty brucellosis free calves with zero titres to the serum agglutination test (SAT), complement fixation test (CFT) and antiglobulin test (ABGT) were vaccinated with strain 19 at ages from seven hours to 198 days. Calves 75 days of age and older responded with normal serological patterns, developing high titres to all three tests. At 45 days and younger most calves responded with much reduced titres, some were negative to the SAT and CFT but all develped titres to the ABGT. Two of the younger group were subjected to an anamnestic test at about a year old and gave a positive response, indicating that the calf may be effectively primed with S19 as early as the first day of life. Three of the group were colostrumdeprived yet the patterns of their responses were similar to those of the colostrum-fed calves. Seventy-four zero titres calves were vaccinated with killed 45/20 adjuvant vaccine at ages from 60 to 320 days. Up to 200 days of age only seven of 33 calves gave positive response. From 200 to ...
The invention relates to a set of novel immunological adjuvants based upon so called polyladder proteins of nematode worms. These proteins are typified by repeating units separated by a protease cleavage motif of RX(K/R)R or RXFR where R is arginine, X is any amino acid, K is lysine and F is phenylalanine. These motifs are preceded by a cysteine residue at around 7, 8 or 9 residues upstream. Polyladder proteins or fragments of polyladder proteins may be used as immunological adjuvants either mixed with, or conjugated to a vaccine antigen, and will strongly enhance the immune response against the antigen. Conjugation may take the form of a genetic fusion between adjuvant and antigen. Antigens may be derived from pathogens, or may be tumour antigens, autoantigens, or antigens of other kinds. Vaccines may be used for prophylaxis or therapy ...

While cytokine adjuvant use has been limited due to toxicity and immunogenicity, they do have potential in DNA vaccines coexpressed with an antigen. Cytokine adjuvant use has been used t oaffect magnitude and direction of immune responses in animal models. Many cytokines, such as IL-12 stimulate macrophage activation via TLR signaling.
In this study, we report the development of a novel, rationally designed immunostimulatory adjuvant based on chemical conjugation of CpG oligodeoxynucleotide (ODN) to the nontoxic B subunit of cholera toxin (CTB). We demonstrate that the immunostimulatory effects of CpG can be dramatically enhanced by conjugation to CTB. Thus, CpG ODN linked to CTB (CTB-CpG) was shown to be a more potent stimulator of proinflammatory cytokine and chemokine responses in murine splenocytes and human PBMCs than those of CpG ODN alone in vitro. The presence of CpG motif, but not modified phosphorothioate ODN backbone, was found to be critical for the enhanced immunostimulatory effects of CTB-CpG. Our mode-of-action studies, including studies on cells from specifically gene knockout mice suggest that similar to CpG, CTB-CpG exerts its immunostimulatory effects through a TLR9/MyD88- and NF-kappaB-dependent pathway. Surprisingly, and as opposed to CpG ODN, CTB-CpG-induced immunity was shown to be independent of ...
Adjuvants are molecules, compounds or macromolecular complexes that boost the potency and longevity of the specific immune response to antigens (1). Most adjuvant research has been an empirical process until recently, when an increased understanding of the mechanisms of immune response induction and the essential bridging of innate and adaptive immune responses has paved the way to a more rational adjuvant design. These breakthrough advances involve a deeper knowledge of how the innate immune system acts to recognize pathogens and damage-associated signals and how this recognition by different receptors may ultimately influence the potency and polarization of the immune responses.. A functional classification of adjuvants was elaborated by Schijns (2), categorizing these molecules as facilitators of signal 1 (delivery of antigen) or signal 2 (i.e., appropriate immunostimulation; costimulation). Later, Valenti and OHagan (3) divided adjuvants into immune potentiators (IP) and delivery systems ...

Immune challenges during early development, including those vaccine-induced, can lead to permanent detrimental alterations of the brain and immune function. Experimental evidence also shows that simultaneous administration of as little as two to three immune adjuvants can overcome genetic resistance to autoimmunity. In some developed countries, by the time children are 4 to 6 years old, they will have received a total of 126 antigenic compounds along with high amounts of aluminum (Al) adjuvants through routine vaccinations. According to the US Food and Drug Administration, safety assessments for vaccines have often not included appropriate toxicity studies because vaccines have not been viewed as inherently toxic. Taken together, these observations raise plausible concerns about the overall safety of current childhood vaccination programs. When assessing adjuvant toxicity in children, several key points ought to be considered: (i) infants and children should not be viewed as small adults with ...
New efficient vaccines against infectious diseases are in demand. Some important factors impeding the vaccine development are the poor immunogenicity and the MHC restriction of the immune responses to a number of antigens. The use of novel vaccine adjuvants or carrier proteins, which are known to enhance the immunogenicity of the subunit antigens and provide T-cell help, can circumvent these problems. The potential of heat shock proteins (HSPs) to function as adjuvants when fused to or co-delivered with protein antigens, make them attractive vaccine candidates. In this thesis we have evaluated the potency of heat shock protein 70 (HSP70) as a possible vaccine adjuvant and studied the mechanisms behind the adjuvanticity.. The first article aims to evaluate the carrier effect of glutathione-S-transferase (GST) on a malarial antigen EB200 that induces a MHC restricted response in mice.

To augment the immune responses elicited by these and other vaccines, scientists use immunologic adjuvants. Currently, only one adjuvant -- alum, first discovered in 1926 -- is incorporated into vaccines licensed for human use by the U.S. Food and Drug Administration (FDA). An adjuvant may work well with one experimental vaccine and not another. Therefore, the FDA licenses the vaccine formulation, or the antigen-adjuvant combination, rather than the adjuvant alone. Experimental adjuvants can increase the type, strength and durability of immune responses evoked by an experimental vaccine. For example, some vaccine antigen/adjuvant combinations can induce cell-mediated immune responses, even if the vaccine antigen by itself does not. Some adjuvants also stimulate mucosal immunity. Alum primarily increases the strength of antibody responses generated by the vaccine antigen. Because of its limited activity, other adjuvants may be better suited for the newer candidate HIV vaccines ...
Immunological adjuvants obtainable from already-known water-soluble adjuvants containing peptidoglycane fragments, which include saccharide units formed from N-acetylglucosamine and from an N-acyl-muramic acid wherein the acyl group is a glycolyl or acetyl group and to the muramyl group there are attached peptide chains, by modification of said already-known water-soluble adjuvants so that they bear acylating groups derived from physiologically-acceptable carboxylic polyacids, especially carboxylic diacids, and wherein preferably the acylating groups themselves include free carboxylic acid groups, for instance being derived from phthalic acid or succinic acid.
Immunostimulants, also known as immunostimulators, are substances (drugs and nutrients) that stimulate the immune system by inducing activation or increasing activity of any of its components. One notable example is the granulocyte macrophage colony-stimulating factor. There are two main categories of immunostimulants: Specific immunostimulants provide antigenic specificity in immune response, such as vaccines or any antigen. Non-specific immunostimulants act irrespective of antigenic specificity to augment immune response of other antigen or stimulate components of the immune system without antigenic specificity, such as adjuvants and non-specific immunostimulators. Many endogenous substances are non-specific immunostimulators. For example, female sex hormones are known to stimulate both adaptive and innate immune responses. Some autoimmune diseases such as lupus erythematosus strike women preferentially, and their onset often coincides with puberty. Other hormones appear to regulate the immune ...

One approach to improve the immunogenicity of an HIV-1 subunit protein vaccine is to combine the immunogen with an adjuvant. Adjuvants may augment vaccine immunogenicity by several mechanisms, and as a result induce a more favorable antibody response with high titers, which appear earlier in the course of immunization and persist over time.. Volunteers are randomized to receive 50 mcg rgp120/HIV-1SF2 in combination with one of seven different adjuvants: aluminum hydroxide (alum), monophosphoryl lipid A, liposome-encapsulated monophosphoryl lipid A, MF59, MTP-PE/MF59, Syntex adjuvant formulation (SAF/2), and SAF/2 plus threonyl muramyl dipeptide (threonyl MDP). An additional placebo control arm of volunteers receive alum only. Doses are administered at 0, 2, and 6 months. Volunteers are followed for 1 year after the last immunization. Per 8/5/94 amendment, eligible volunteers except those who received monophosphoryl lipid A for the first three immunizations may receive a fourth dose at month ...
Most purified protein and peptide antigens are poorly immunogenic so adjuvants must be included in vaccines to activate and direct adaptive immune responses. The most commonly used adjuvants in clinical use are aluminium salts, particularly aluminium hydroxide adjuvant, which is chemically crystalline aluminium oxyhydroxide 1, 2 and comprises nanoparticles that form porous aggregates of 1-20 μm in diameter 2. Although not technically correct, aluminium-containing adjuvants are generally referred to as alum. Alum is not an optimal adjuvant for all protein antigens and is a relatively poor inducer of cell-mediated immunity. As a result, other particulate adjuvants, including chitosan, liposomes and biodegradable microparticles and nanoparticles are being investigated 3. However, despite the widespread use of particulates in both clinical and research settings for over 80 years, their mode of action is still not fully understood.. In 2007 it was found that aluminium-containing adjuvants enhanced ...
The invention consists of oligonucleotides which inhibit the immunostimulatory activity of ISS-ODN (immunostimulatory sequence oligodeoxynucleotides) as well as methods for their identification and use. The oligonucleotides of the invention are useful in controlling therapeutically intended ISS-ODN adjuvant activity as well as undesired ISS-ODN activity exerted by recombinant expression vectors, such as those used for gene therapy and gene immunization. The oligonucleotides of the invention also have anti-inflammatory activity useful in reducing inflammation in response to infection of a host with ISS-ODN containing microbes, in controlling autoimmune disease and in boosting host Th2 type immune responses to an antigen. The invention also encompasses pharmaecutically useful conjugates of the oligonucleotides of the invention (including conjugate partners such as antigens and antibodies).
New vaccines are presently under development and in testing for the control of infectious diseases, including human immunodeficiency virus (HIV) and tuberculosis. Several of these vaccines are composed of synthetic, recombinant, or highly purified subunit antigens. Subunit vaccines are designed to include only the antigens required for protective immunization and to be safer than whole-inactivated or live-attenuated vaccines. However, the purity of the subunit antigens and the absence of the self-adjuvanting immunomodulatory components associated with attenuated or killed vaccines often result in weaker immunogenicity. Immunologic adjuvants are agents that enhance specific immune responses to vaccines. Formulation of vaccines with potent adjuvants is an attractive approach for improving the performance of vaccines composed of subunit antigens. Adjuvants have diverse mechanisms of action and should be selected for use on the basis of the route of administration and the type of immune response ...
Vaccine adjuvants facilitate the production of long-lasting, efficient and specific immune responses and improve the protective effect of vaccines due to a higher antibody yield and the persistence of antibodies, as well as functional T cells at high levels. Currently, the most common adjuvant used in experimental animals is Freunds adjuvants, which can enhance strong antigen-specific immune responses. However, it causes strong inflammation and necrosis at the injection site, which prevents its use in vaccine development. Aluminium-derived adjuvants are often used in clinical trials and have the reputation of safety and the facilitation of long-lasting antibody responses [1], but the effect on cell-mediated immunity remains questionable when used along with small immunogenic antigens. To develop safe and effective adjuvants for enhancing both humoral and cellular immune responses, we focused on the selection of novel immunofacilitators based on their roles in initiating innate and adaptive ...
To generate vaccines that protect mucosal surfaces, a better understanding of the cells required in vivo for activation of the adaptive immune response following mucosal immunization is required. CD11c(high) conventional dendritic cells (cDCs) have been shown to be necessary for activation of naive CD8(+) T cells in vivo, but the role of cDCs in CD4(+) T cell activation is still unclear, especially at mucosal surfaces. The activation of naive Ag-specific CD4(+) T cells and the generation of Abs following mucosal administration of Ag with or without the potent mucosal adjuvant cholera toxin were therefore analyzed in mice depleted of CD11c(high) cDCs. Our results show that cDCs are absolutely required for activation of CD4(+) T cells after oral and nasal immunization. Ag-specific IgG titers in serum, as well as Ag-specific intestinal IgA, were completely abrogated after feeding mice OVA and cholera toxin. However, giving a very high dose of Ag, 30-fold more than required to detect T cell ...

We here study the adjuvant properties of immunostimulatory DNA sequences (ISS) and coinjected cytokine-coding cDNA in suppressive vaccination with DNA encoding an autoantigenic peptide, myelin basic protein peptide 68-85, against Lewis rat experimental autoimmune encephalomyelitis (EAE). EAE is an autoaggressive, T1-mediated disease of the CNS. ISS are unmethylated CpG motifs found in bacterial DNA, which can induce production of type 1 cytokines in vertebrates through the innate immune system. Because ISS in the plasmid backbone are necessary for efficient DNA vaccination, we studied the effect of one such ISS, the 5-AACGTT-3 motif, in our system. Treatment with a DNA vaccine encoding myelin basic protein peptide 68-85 and containing three ISS of 5-AACGTT-3 sequence suppressed clinical signs of EAE, while a corresponding DNA vaccine without such ISS had no effect. We further observed reduced proliferative T cell responses in rats treated with the ISS-containing DNA vaccine, compared with ...
Vaccines against pneumococcal disease for use in developing countries should be safe, effective against a broad range of serotypes and affordable. The existing conjugate vaccines offer protection against the serotypes included in the vaccine which were selected based on their prevalence in North America and Europe, and are predicted to provide incomplete protection against pneumococcal infections in Asia and Africa. In addition, these conjugate vaccines are expensive to produce. The work in this report demonstrates that a vaccine composed of killed whole cell, nonencapsulated pneumococci and formulated with AH, induces a strong antibody and IL-17 response. Both the antigen and adjuvant are relatively inexpensive suggesting that the vaccine will be affordable for use in developing countries.. Previous work with a simple protein antigen, alpha casein, indicated that the strength of adsorption of antigens onto aluminum-containing adjuvants is inversely related to the antibody response to these ...
Medical definition of immunoadjuvant: a nonspecific substance acting to enhance the immune response to an antigen with which it is administered
Modern adjuvants should induce strong and balanced immune responses, and it is often desirable to induce specific types of immunity. As an example, efficient Th1-immunity-inducing adjuvants are highly in demand. Such adjuvants promote good cell-mediated immunity against subunit vaccines that have low immunogenicity themselves. The development of such adjuvants may take advantage of the increased knowledge of the molecular mechanisms and factors controlling these responses. However, knowledge of such molecular details of immune mechanisms is relatively scarce for species other than humans and laboratory rodents, and in addition, there are special considerations pertaining to the use of adjuvants in veterinary animals, such as production and companion animals. With a focus on veterinary animals, this review highlights a number of approaches being pursued, including cytokines, CpG oligonucleotides, microparticles and liposomes. ...

Vaccine damage via adjuvants.. Although in contemporary vaccine history, aluminium adjuvants have been portrayed as inherently safe (Offit and Jew, 2003), studies in animal models and humans have demonstrated their ability to inflict immuno-inflammatory conditions by themselves (Authier et al., 2001; Petrik et al., 2007; Couette et al., 2009; Israeli et al., 2009; Shaw and Petrik, 2009; Gherardi and Authier, 2012).. There is no legal or medical requirement to demonstrate that aluminium adjuvants are without risk for human use and there is no approval mechanism. Only vaccines are approved for human use. There are two commonly used aluminium adjuvants, Alhydrogel® and AdjuPhos®, as well as a sulphated version of the latter, which is included in Gardasil, a vaccine against the human papilloma virus (HPV). Mercks own safety trial data suggest a frequency of adverse events for the vaccine of approximately 2.5% and similarly 2.5% for their placebo group who received their proprietary adjuvant. ...

Of 17 evaluable patients, five developed specific anti-vaccine antibodies, and eight developed anti-Fab T-cell responses. T-cell reactivity was independent of the cellular immune status and was idiotype specific as shown by statistical regression analysis (P = 0.0024) and epitope mapping studies. Intradermal administration of uncoupled recombinant idiotype with appropriate adjuvants may overcome profound clinical immunosuppression and induce specific immune responses. ...
The introduction of vaccines is regarded as one of the most successful medical interventions to date, due to their effectiveness at combating diseases that require the induction of a robust immune response. However there is a clear need for the development of new vaccines for diseases including HIV, TB and malaria and for cancer which require the induction of a potent cellular immune response. Advancements in the field of vaccine research have resulted in a move away from the use of whole organisms and towards the use of subunit vaccines which consist of highly purified antigens and thus offer a much more attractive safety profile. Adjuvants are immunostimulatory components that are included in subunit vaccine formulations to help to direct and amplify an appropriate adaptive immune response. The most commonly used adjuvant to date, alum, is incorporated into vaccine formulations that are aimed at inducing humoral immune responses however alum is a poor inducer of cellular immune re... ...

  • The goal of vaccination is induction of protective immunity and in some vaccines this can be enhanced by addition of adjuvants. (
  • Surprisingly, despite the wide use of vaccine adjuvants in billions of doses of human and animal vaccines, the mechanisms of action by which they potentiate immune responses are not well characterized. (
  • CONCLUSIONS: Our data demonstrate the potency of cytokine-encoding vectors as adjuvants and immune modulators in composite vaccines for anti-retroviral immunization. (
  • ISCOMATRIX adjuvant: an adjuvant suitable for use in anticancer vaccines. (
  • After about 70 years two new adjuvants have been approved for human vaccines. (

  • Formaldehyde is recognized as a potent adjuvant which causes foreign proteins to be recognized as antigens by the immune system, triggering immune responses to destroy them. (
  • EMAILWIRE.COM, December 06, 2017 ) Vaccine adjuvants are desirable to expand the adaptive immune reactions to antigens. (
  • Adjuvants are used to improve or enhance an immune response to antigens. (
  • Adjuvants are generally used with soluble protein antigens to increase antibody titers and induce a prolonged response with accompanying memory. (
  • Immune responses to non-protein antigens are generally poorly or enhanced by adjuvants and there is no system memory. (
  • However, more uniquely among adjuvant classes, they induce antigen-specific IgA antibodies and long-lasting memory to coadministered antigens when delivered mucosally or even parenterally. (

(
  • Bacillus subtilis spores as adjuvants against avian influenza H9N2 induce antigen-specific antibody and T cell responses in White Leghorn chickens. (

  • Another important area of emphasis is research on activation of the innate immune system by vaccine adjuvants and establishment of long-term protective antibody and T-cell memory responses. (
  • The polymeric adjuvants provides 2-10 times higher antibody titers comparing with standard (complete Freund's adjuvant). (
  • Freund later found that immunization of the protein antigen in a water-in-paraffin oil emulsion without killed mycobacteria was just as effective in increasing and prolonging antibody formation[ 3 ], leading to the development of incomplete Freund's adjuvant (IFA) which is a water-in-oil (W/O) emulsion without killed mycobacteria. (
  • Adjuvant chemoradiotherapy: Within 16-28 days after the first vaccination, patients receive fluorouracil (5-FU) IV continuously for 3 weeks. (
  • Here we investigated the effects of DNA vaccination with the whole CD25 gene on the induction of rat adjuvant arthritis. (

  • In this study we have investigated the induction of systemic and mucosal immune responses to HIV gp120 monomer immunogen administered intranasally in a novel, oil-in-water nanoemulsion (NE) adjuvant. (
  • Our results show how polymeric particulate-carriers can be adopted to safely deliver combinatorial adjuvants and selectively synergize specific types of immune responses for vaccine applications. (
  • It appears that adjuvants activate innate immune responses to create a local immuno-competent environment at the injection site. (
  • Depending on the type of innate responses activated, adjuvants can alter the quality and quantity of adaptive immune responses. (
  • First, it provides the knowledge and analytical tools for understanding the immunologic basis of protective immune responses as well as a framework for approaching studies of adverse events. (
  • dmLT is an adjuvant that enhances vaccine-specific systemic and mucosal immune responses following mucosal or parenteral delivery, described in detail below (e.g. (
  • 3) Unlike other adjuvants, such as aluminum hydroxide or many Toll-like receptor (TLR)-based adjuvants (e.g., monophosphoryl lipid A [MPL] and CpG), dmLT induces strong interleukin-17 (IL-17) recall cytokine secretion and antigen-specific Th17 responses after parenteral or mucosal immunization ( 7 - 15 ).

  • There are many known adjuvants in widespread use, including aluminium salts, oils and virosomes . (
  • Two fundamental challenges plague clinical translation of vaccine-adjuvants: reducing acute toxicities that result from systemic diffusion of many soluble adjuvants, and delivering multiple adjuvants at the same time to mimic the synergistic immune-stimulation of pathogens, while being safe. (
  • Thus, unlike many depot-type adjuvants, such as aluminum hydroxide, no advanced preparation or absorption is required to formulate the antigen/adjuvant vaccine. (

  • Adjuvants accomplish this task by mimicking specific sets of evolutionarily conserved molecules, so called PAMPs , which include liposomes , lipopolysaccharide (LPS), molecular cages for antigen , components of bacterial cell walls , and endocytosed nucleic acids such as double-stranded RNA ( dsRNA ), single-stranded DNA ( ssDNA ), and unmethylated CpG dinucleotide-containing DNA . (
  • Some adjuvants work as delivery systems that provide stimulation of the immune system. (
  • Advances in vaccine technology, including new delivery methods and adjuvants, as well as progress in systems biology and an increased understanding of the human immune system, hold the potential to address these issues. (
  • The adjuvant dmLT, or more technically LT(R192G/L211A), is an 84-kDa polymeric protein with an AB 5 structure composed of an enzymatically active A subunit (28 kDa) noncovalently associated with a pentameric B subunit (consisting of five 11.5-kDa monomers) as shown in Fig. 1A . (
  • Currently, there is no widely accepted adjuvant treatment available for these patients, despite the fact that after surgical removal of the primary tumor, they still run a considerable risk of recurrence. (
  • Inorganic compounds: potassium alum, aluminium hydroxide, aluminium phosphate, calcium phosphate hydroxide Oils: paraffin oil, propolis (only in preclinical studies), Adjuvant 65 (based on peanut oil. (
  • This was based on the ratio of its potency relative to phenylbutazone in producing intestinal lesions to its anti-inflammatory potency relative to phenylbutazone in the adjuvant-induced arthritis. (
  • Chemically, the adjuvants are a highly heterogenous group of compounds with only one thing in common: their ability to enhance the immune response - their adjuvanticity. (
  • adjuvant disease, onemocnění z adjuvantů). (
  • Preclinical and clinical trials have been performed with a variety of adjuvants, and although some have been immunologically effective, most have been too toxic for routine use. (
  • Exley C. Aluminium-based adjuvants should not be used as placebos in clinical trials. (
  • The properties and clinical potential of these different classes of adjuvants are being discussed. (
