Immunostimulation in the urinary bladder by local application of Nocardia rubra cell-wall skeletons (Rubratin) and bacillus Calmette-Guerin as therapy for superficial bladder cancer: a comparative study. (1/25)Twelve patients with superficial bladder cancer were treated with intravesical instillations of Rubratin (ASTA Pharma AG, Frankfurt, Germany), a cell-wall preparation of Nocardia rubra. The objective was to compare the immunostimulating effect of Rubratin with that of bacillus Calmette-Guerin (BCG). Local immunostimulation was determined by cytokine induction in serially collected urine samples during the first 24 h after each instillation, leukocyte influx into the urine, and phenotypic analysis of the lymphocyte fraction. Levels of Rubratin-induced interleukin (IL)-1 beta, IL-6, and tumor necrosis factor-alpha were significantly elevated compared with pretherapy levels. Rubratin induced leukocyte influx into the urine. T-cell activation (IL-2 receptor and human leukocyte antigen-DR expression) can be induced, and CD4:CD8 cell ratios can be increased. All parameters indicated that Rubratin-induced immunostimulation was less than that associated with BCG. In conclusion, although local Rubratin-induced immunostimulation occurs in a limited number of patients, the amount of immunocompetent cells attracted to the bladder seems to be less than that associated with BCG therapy, thus resulting in lower levels of cytokine production (which may reflect less clinical efficacy).

Maturation of human dendritic cells by cell wall skeleton of Mycobacterium bovis bacillus Calmette-Guerin: involvement of toll-like receptors. (2/25)The constituents of mycobacteria are an effective immune adjuvant, as observed with complete Freund's adjuvant. In this study, we demonstrated that the cell wall skeleton of Mycobacterium bovis bacillus Calmette-Guerin (BCG-CWS), a purified noninfectious material consisting of peptidoglycan, arabinogalactan, and mycolic acids, induces maturation of human dendritic cells (DC). Surface expression of CD40, CD80, CD83, and CD86 was increased by BCG-CWS on human immature DC, and the effect was similar to those of interleukin-1beta (IL-1beta), tumor necrosis factor alpha (TNF-alpha), heat-killed BCG, and viable BCG. BCG-CWS induced the secretion of TNF-alpha, IL-6, and IL-12 p40. CD83 expression was increased by a soluble factor secreted from BCG-CWS-treated DC and was completely inhibited by monoclonal antibodies against TNF-alpha. BCG-CWS-treated DC stimulated extensive allogeneic mixed lymphocyte reactions. The level of TNF-alpha secreted through BCG-CWS was partially suppressed in murine macrophages with no Toll-like receptor 2 (TLR 2) or TLR4 and was completely lost in TLR2 and TLR4 double-deficient macrophages. These results suggest that the BCG-CWS induces TNF-alpha secretion from DC via TLR2 and TLR4 and that the secreted TNF-alpha induces the maturation of DC per se. (+info)
Immunization with a polyprotein vaccine consisting of the T-Cell antigens thiol-specific antioxidant, Leishmania major stress-inducible protein 1, and Leishmania elongation initiation factor protects against leishmaniasis. (3/25)Development of an effective vaccine against Leishmania infection is a priority of tropical disease research. We have recently demonstrated protection against Leishmania major in the murine and nonhuman primate models with individual or combinations of purified leishmanial recombinant antigens delivered as plasmid DNA constructs or formulated with recombinant interleukin-12 (IL-12) as adjuvant. In the present study, we immunized BALB/c mice with a recombinant polyprotein comprising a tandem fusion of the leishmanial antigens thiol-specific antioxidant, L. major stress-inducible protein 1 (LmSTI1), and Leishmania elongation initiation factor (LeIF) delivered with adjuvants suitable for human use. Aspects of the safety, immunogenicity, and vaccine efficacy of formulations with each individual component, as well as the polyprotein referred to as Leish-111f, were assessed by using the L. major challenge model with BALB/c mice. No adverse reactions were observed when three subcutaneous injections of the Leish-111f polyprotein formulated with either MPL-squalene (SE) or Ribi 529-SE were given to BALB/c mice. A predominant Th1 immune response characterized by in vitro lymphocyte proliferation, gamma interferon production, and immunoglobulin G2A antibodies was observed with little, if any, IL-4. Moreover, Leish-111f formulated with MPL-SE conferred immunity to leishmaniasis for at least 3 months. These data demonstrate success at designing and developing a prophylactic leishmaniasis vaccine that proved effective in a preclinical model using multiple leishmanial antigens produced as a single protein delivered with a powerful Th1 adjuvant suitable for human use.

Effect of vaccination with refined components of the organism on infection of mice with Mycobacterium leprae. (4/25)Only native products of Mycobacterium leprae, whether cell wall, cytosol, or membrane derived, can confer protective immunity against challenge in the mouse footpad. Previously, recombinant proteins were shown to be ineffective. The cell wall skeleton-the mycolyl-arabinogalactan-peptidoglycan complex-devoid of proteins is not protective. (+info)
Mycobacterium bovis BCG cell wall-specific differentially expressed genes identified by differential display and cDNA subtraction in human macrophages. (5/25)We have analyzed the gene expression profile of monocytes in response to a highly purified cell wall fraction of Mycobacterium bovis BCG, a clinically approved adjuvant known as BCG cell wall skeleton (BCG-CWS). It is composed of mycolic acid, arabinogalactan, and peptidoglycan and confers Toll-like receptor 2 (TLR2)- and TLR4-dependent signaling that induces monocytes to differentiate into antigen-presenting cells (APCs). Here we report differential gene expression analysis with BCG-CWS-stimulated versus nonstimulated monocytes. BCG-CWS exerted massive induction of genes regulated by TLR signaling. Marked gene regulatory characteristics in BCG-CWS-stimulated cells compared to lipopolysaccharide (LPS)-stimulated cells follow. (i) Spliced mRNAs encoding soluble forms of TREM-1 and TREM-2 (recently discovered inflammatory-signal-amplifying receptors) were regulated by BCG-CWS, resulting in their differential expression. (ii) The genes for zinc-iron transporter protein (ZIP)-like family proteins HKE-1 and LIV-1 were induced exclusively by BCG-CWS. (iii) Interleukin-23 (IL-23), rather than IL-12p70, was induced by BCG-CWS, while interferon-inducible genes were induced only by LPS. By Northern and reverse transcription-PCR analyses, we confirmed the differential expression of more than 30 BCG-CWS regulatory genes, and their expression was compared with that of LPS and other known TLR ligands. A battery of genes responded rapidly and for a short time to LPS but for a long time to BCG-CWS. Structural analysis of the identified novel or hypothetical proteins revealed that some are potential candidates as signaling mediators or transcriptional regulators. Hence, BCG-CWS may profoundly modulate APC responses in a way distinct from that of LPS, leading to possible advantages for its adjuvant-active therapeutic potential. (+info)
The role of adjuvant on the regulatory effects of NK cells on B cell responses as revealed by a new model of NK cell deficiency. (6/25)We have utilized a novel method to generate transgenic mice that are deficient in NK cells. The strategy entails introduction of the H and L chain genes encoding PK136, an antibody shown to be effective in the in vivo elimination of NK cells, into the mouse genome. Since the introduced H chain gene does not contain sequences encoding membrane exons, the transgenic Ig is not expressed on the cell surface, but is secreted by activated B cells. We show that these animals are chronically depleted of NK cells, but not B, T or NKT cells. Therefore, they are compromised in their ability to mediate NK-mediated cytotoxicity. In addition, the deficiency in NK cells reduces the level of switching to various downstream isotypes in response to T-independent type II antigens. However, this reduction is only apparent when antigens are injected in the presence of adjuvant. Since NKT cells are not depleted, the effect cannot be attributed to this subpopulation. These results help to resolve differences in previous findings regarding the role of NK cells in antibody responses. (+info)
Protective immunity to vaccinia virus induced by vaccination with multiple recombinant outer membrane proteins of intracellular and extracellular virions. (7/25)Infectious intracellular and extracellular forms of vaccinia virus have different outer membrane proteins, presenting multiple targets to the immune system. We investigated the immunogenicity of soluble forms of L1, an outer membrane protein of the intracellular mature virus, and of A33 and B5, outer membrane proteins of the extracellular enveloped virus. The recombinant proteins, in 10-microg amounts mixed with a Ribi- or saponin-type adjuvant, were administered subcutaneously to mice. Antibody titers to each protein rose sharply after the first and second boosts, reaching levels that surpassed those induced by percutaneous immunization with live vaccinia virus. Immunoglobulin G1 (IgG1) antibody predominated after the protein immunizations, indicative of a T-helper cell type 2 response, whereas live vaccinia virus induced mainly IgG2a, indicative of a T-helper cell type 1 response. Mice immunized with any one of the recombinant proteins survived an intranasal challenge with 5 times the 50% lethal dose of the pathogenic WR strain of vaccinia virus. Measurements of weight loss indicated that the A33 immunization most effectively prevented disease. The superiority of protein combinations was demonstrated when the challenge virus dose was increased 20-fold. The best protection was obtained with a vaccine made by combining recombinant proteins of the outer membranes of intracellular and extracellular virus. Indeed, mice immunized with A33 plus B5 plus L1 or with A33 plus L1 were better protected than mice immunized with live vaccinia virus. Three immunizations with the three-protein combination were necessary and sufficient for complete protection. These studies suggest the feasibility of a multiprotein smallpox vaccine. (+info)
Evaluation of lipopolysaccharide and capsular polysaccharide as subunit vaccines against experimental melioidosis. (8/25)Burkholderia pseudomallei is the causative agent of melioidosis, which is a major cause of morbidity and mortality in endemic regions. Currently there is no human vaccine against melioidosis. In this study, LPS or capsular polysaccharide was used to immunize BALB/c mice. The different polysaccharide antigens induced antibody responses. Mice vaccinated with LPS developed predominantly IgM and IgG3 responses. Contrastingly, mice vaccinated with capsular polysaccharide developed a predominantly IgG2b response. After immunization, mice were challenged by the intra-peritoneal route and an increased mean time to death was observed compared with unvaccinated controls. Immunization with LPS provided an optimal protective response. Mice challenged by the aerosol route showed a small increase in the mean time to death compared with the unvaccinated controls. The passive transfer of antigen from immunized into naive mice provided protection against a subsequent challenge. This study is the first time antigens protective by active immunization have been identified and suggests that polysaccharides have potential as vaccine candidates against melioidosis. (+info)

Primary growth of AMC 60 fibrosarcoma inoculated into the hind leg of ACI/N rats resulted in occasional generation of concomitant resistance to growth of a second graft of the same tumor cells in the peritoneal or pleural cavity. Using this syngeneic tumor-host system, experiments were carried out to elucidate the effect of intratumoral injections of an immunomodulator, Nocardia rubra cell wall skeleton (N-CWS), on concomitant immunity. Rats bearing a solid tumor into which N-CWS was repeatedly injected showed a significant inhibitory effect on the proliferation of the tumor cells inoculated secondarily into the peritoneal cavity, i.e., concomitant immunity, as compared to control groups of normal, N-CWS-treated and solid tumor-bearing rats. Peritoneal macrophages, when harvested after i.p. tumor inoculation into the N-CWS treated solid tumor-bearing rats, were found to be significantly potentiated for tumoricidal activity against [5-125I]iodo-2′-deoxyuridine-labeled AMC tumor cells. These ...
The purpose of this study was to determine whether the presence of progressively growing pulmonary metastases influences the number and function of alveolar macrophages (AM). Female F344 rats were given i.v. injections of cells from a metastatic variant line of the syngeneic adenocarcinoma MADB-105. At Days 7, 14, 21, and 28 after injection, normal and tumor-bearing animals (3/group) were killed, and their AM were harvested by lavage. The functional integrity of AM was determined by their capacity to phagocytose opsonized erythrocytes and by their ability to respond to a variety of activating agents in vitro. Normal and metastasis-bearing rats were given i.v. injections of Nocardia rubra cell wall skeleton to determine whether the presence of large pulmonary metastases would interfere with AM activation in situ. The data demonstrated that the presence of progressively growing lung metastases led to a slight increase in the number of harvested AM and that these cells from tumor-bearing rats were ...
Galactosamine was found consistently as a minor component of the envelope of five species of slow-growing mycobacteria, including all the major human pathogens, but not three rapid-growing species. The amino sugar was a component of the arabinogalactan of the cell wall skeleton, and occurred at the level of about one residue per arabinogalactan chain. Its amino group was in the free, un-N-acetylated state. Examination of oligosaccharides released by partial acid hydrolysis of arabinogalactan by fast atom bombardment-MS and gas chromatography-MS identified a series of oligoarabinans, each possessing one GalN unit, linked to position 2 of arabinose. It is proposed that the GalN residues occur as stub branches of 1 → 5-linked arabinose chains in the arabinogalactan. Possible functions of GalN are discussed.. ...

Answer Poison gas was used to blind the enemy on the other side . It is a very strong and dangerous chemical. Additional answer There are actually many different poison gases. The simplest is the element chlorine. But there are others which have different effects. But basically they all kill, not just blind.

Mycobacterium vaccae is a nonpathogenic species of the Mycobacteriaceae family of bacteria that lives naturally in soil. Its name originates from the Latin word, vacca (cow), since it was first cultured from cow dung in Austria. Research areas being pursued with regard to killed Mycobacterium vaccae vaccine include immunotherapy for allergic asthma, cancer, depression, leprosy, psoriasis, dermatitis, eczema and tuberculosis. A research group at Henry Wellcome Laboratories for Integrative Neuroscience and Endocrinology, University of Bristol, Bristol, England, UK has shown that Mycobacterium vaccae stimulated a newly discovered group of neurons, increased levels of serotonin and decreased levels of anxiety in mice. Other researchers fed live Mycobacterium vaccae to mice, then measured their ability to navigate a maze compared to control mice not fed the bacteria. "Mice that were fed live M. vaccae navigated the maze twice as fast and with less demonstrated anxiety behaviors as control mice", ...
Okunojima, a small island in the Inland Sea of Japan, off the shore of Takehara city was notorious for the production of poison gases from 1927 to 1945. Of the gases produced there, yperite and lewisite were the most poisonous and caused severe residual damage." (Testimony of Dr. Christine M. Gosden on Chemical and Biological Weapons Threats to America: Are We Prepared? April 22nd, 1998). Pictures of the former gas poison factory on Okunojima (page in Japanese). Allegedly, the poison gas factory on Okunojima was so secret that trains driving past the island on the coast had their windows facing the sea barred. In 1945, the workers, who included many forced labourers from China and Korea, were liberated, as were the many rabbits used in experiments. The workers left. The rabbits stayed. Today Okunojima is a beautiful spot in the Inland Sea, with a museum on poison gas in general and its production on Okunojima in particular, with a holiday resort and a beach, and myriads of freely roaming, very ...

It seems that exposure to M vaccae, i.e. getting it "under your skin", boosts your immune system and improves your brain chemistry. So now there is a scientific "reason" for feeling good after youve worked in your garden or out in the yard, beyond the fresh air and sunshine. These bacteria get into your system and one result of the immune cascade is that serotonin production in your brain increases. More serotonin elevates your mood and has a few other positive mental effects that I recall studying some years ago ...

he was exposed to poison gas, was hospitalized with lung injury, and was subsequently medically discharged from service and consigned to a pension. Returning to Tampa, he took employment as a reporter for the "Tampa Tribune," where he worked until 1936, when he moved to Hollywood. At some point after his exposure to the poison gas, he also developed acromegaly, a slowly progressive deforming of bones in the head, hands and feet, and internal and external soft tissues caused by disease of the pituitary gland, which onsets after the individual has reached his full genetic height (under normal pituitary influence), and production of growth hormones resume, but the bone structure can no longer produce symmetric growth (as in giantism). According to all authors, his acromegaly was a result of the poison gas, though typically, it is caused by a tumor on the pituitary. In any event, his worsening disfigurement is thought to have led to his first divorce and certainly was responsible for his being ...
Edit: Now that I think of it, maybe poison gas would double the effects of regular poison, but not poison or do damage to anything that isnt already. Toxic would get turned into regular poison with this move.. The poison status: Poisoning should do 1/8th of HP a turn (doesnt it already?). It would lower defense or special by 2 stages, or both by 1 stage. It could also lower evade or accuracy instead. In order to keep regular poison useful, perhaps Toxic wont give you the benefits of stat lowering.. Psywave: Instead of between 1 HP and 1.5x your level, make it 0.75x and 1.5x your level. String shot: This is only a maybe, but make it lower accuracy or trap the opponent like wrap as well as lower speed.. Multi attacks: Comet Punch, Pin missle, fury attack etc. They should be fixed in some way, but Im not sure how. Perhaps a stat lowering effect or a status effect, or something that effects switching.. Dizzy Punch: should have a 30 - 40% chance of confusing the enemy. Constrict: Should be ...

The Effect of Monophosphoryl Lipid A on Maturation of DCs from Patients with Acute Myeloid Leukaemia
Background: Generation of monocyte-derived dendritic cells (MDDC) is induced in the presence of GM-CSF and IL-4, and a maturation stimulus is added to the monocyte culture to obtain mature Dendritic Cells (DCs) suitable for therapy. TNF-α is the most common cytokine used for activating DCs and generating mature MDDC either alone or in combination with other cytokines. Objective: To compare effects of traditional cytokine cocktail (TNF-α + IL-1β) versus TLR4-agonist monophosphoryl lipid A on the viability, phenotype, cytokine profile and functionality of MDDC. Methods: The study included 32 individuals; twenty Acute Myeloid Leukaemia (AML) cases in complete remission and 12 healthy volunteers. They were divided into 3 groups: Group 1: control group: 12 subjects to measure the baseline levels of all markers in the monocytic preparation; Group 2: cytokine cocktail (TNF-α) group, which included 10 AML subjects; Group 3: MPLA group which included 10 AML subjects. Results: TNF-α group showed higher

Local immunostimulation leading to rejection of accepted male skin grafts by female mice as a model for cancer immunotherapy ...
Female mice of inbred strain CBA do not reject syngeneic male skin grafts even though they mount a T-cell response against the male-specific HY antigen. We show that local immunostimulation performed by injecting cytokines and Toll-like receptor ligands in close vicinity to the graft causes rejection. We feel that this approach should be tested in tumor-bearing human patients in combination with antitumor vaccination. Relief of intratumor immunosuppression may increase considerably the fraction of patients who respond to vaccination directed against tumor antigens recognized by T cells. ...

- Initially, the immune system protects the host from cancer development and, indeed, the infiltration of NK cells in cancers is associated with a favorable prognosis ( 1 ). (jimmunol.org)
- However, the infiltration of innate-immune cells such as macrophages correlates with a poor prognosis, which suggests that these cells may be directly involved in tumor development and metastasis by inducing angiogenesis and tissue remodeling. (jimmunol.org)
- They also showed that IL-23 is an important molecule that leads to the up-regulation of IL-17 and the matrix metalloprotease 9, to an increase in angiogenesis, and to a reduction in CD8 + T cell infiltration in the tumor microenvironment ( 16 ). (jimmunol.org)
- Rats bearing a solid tumor into which N-CWS was repeatedly injected showed a significant inhibitory effect on the proliferation of the tumor cells inoculated secondarily into the peritoneal cavity, i.e. , concomitant immunity, as compared to control groups of normal, N-CWS-treated and solid tumor-bearing rats.
