Recombinant DNA vectors encoding antigens administered for the prevention or treatment of disease. The host cells take up the DNA, express the antigen, and present it to the immune system in a manner similar to that which would occur during natural infection. This induces humoral and cellular immune responses against the encoded antigens. The vector is called naked DNA because there is no need for complex formulations or delivery agents; the plasmid is injected in saline or other buffers.

Schedule giving optimum times usually for primary and/or secondary immunization.
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.

Bacterial infections of the leptomeninges and subarachnoid space, frequently involving the cerebral cortex, cranial nerves, cerebral blood vessels, spinal cord, and nerve roots.
Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (CARCINOMATOUS MENINGITIS), and other inflammatory conditions may produce this syndrome. (From Joynt, Clinical Neurology, 1994, Ch24, p6)
An acute purulent infection of the meninges and subarachnoid space caused by Streptococcus pneumoniae, most prevalent in children and adults over the age of 60. This illness may be associated with OTITIS MEDIA; MASTOIDITIS; SINUSITIS; RESPIRATORY TRACT INFECTIONS; sickle cell disease (ANEMIA, SICKLE CELL); skull fractures; and other disorders. Clinical manifestations include FEVER; HEADACHE; neck stiffness; and somnolence followed by SEIZURES; focal neurologic deficits (notably DEAFNESS); and COMA. (From Miller et al., Merritt's Textbook of Neurology, 9th ed, p111)
Infections of the nervous system caused by bacteria of the genus HAEMOPHILUS, and marked by prominent inflammation of the MENINGES. HAEMOPHILUS INFLUENZAE TYPE B is the most common causative organism. The condition primarily affects children under 6 years of age but may occur in adults.
A syndrome characterized by headache, neck stiffness, low grade fever, and CSF lymphocytic pleocytosis in the absence of an acute bacterial pathogen. Viral meningitis is the most frequent cause although MYCOPLASMA INFECTIONS; RICKETTSIA INFECTIONS; diagnostic or therapeutic procedures; NEOPLASTIC PROCESSES; septic perimeningeal foci; and other conditions may result in this syndrome. (From Adams et al., Principles of Neurology, 6th ed, p745)
A fulminant infection of the meninges and subarachnoid fluid by the bacterium NEISSERIA MENINGITIDIS, producing diffuse inflammation and peri-meningeal venous thromboses. Clinical manifestations include FEVER, nuchal rigidity, SEIZURES, severe HEADACHE, petechial rash, stupor, focal neurologic deficits, HYDROCEPHALUS, and COMA. The organism is usually transmitted via nasopharyngeal secretions and is a leading cause of meningitis in children and young adults. Organisms from Neisseria meningitidis serogroups A, B, C, Y, and W-135 have been reported to cause meningitis.

The effect of route of immunization on the lapine immune response to killed Pasteurella haemolytica and the influence of aerosol challenge with the live organism. (1/3096)

Appearance of anti-Pasteurella haemolytica antibody in the serum and broncho-alveolar washings of rabbits is independent of the route of immunization and is similar in both locations. The most influential factor in development of a humoral response is exposure to live P. haemolytica and prior exposure to the killed bacterium has no significant effect upon titre determined following aerosol challenge with live organisms.  (+info)

Immune response capacity after human splenic autotransplantation: restoration of response to individual pneumococcal vaccine subtypes. (2/3096)

OBJECTIVE: To evaluate features of general immune function, in particular the restoration of the humoral immune response to pneumococcal capsular polysaccharides, in humans undergoing a spleen autotransplantation after splenectomy because of trauma. SUMMARY BACKGROUND DATA: After splenectomy, patients have an increased risk of overwhelming infection or sepsis involving encapsulated bacteria such as pneumococci. The value of human spleen autotransplantation after splenectomy because of trauma has long been questioned. Mononuclear phagocyte system function appeared to be similar to that in splenectomized persons. The presence of specific antipneumococcal antibodies would allow other parts of the mononuclear phagocyte system, such as those in the liver, to phagocytose opsonized bacteria. METHODS: Ten consecutive patients undergoing splenectomy followed by autotransplantation were compared with the next 14 consecutive patients undergoing splenectomy alone. After a minimum of 6 months, the patients were vaccinated with 23-valent pneumococcal vaccine. Blood samples were taken at the time of vaccination and after 3 and 6 weeks for antipneumococcal capsular polysaccharides IgM and IgG enzyme-linked immunosorbent assay against types 3, 4, 6, 9, 14, and 23. Splenic regrowth was evaluated by scintigraphy. RESULTS: Surprisingly, several of the nonautotransplanted patients showed scintigraphic activity, indicating the presence of either accessory spleens or traumatic seeding (splenosis). Significant antibody titer increases (more than twofold) were found for both IgM and IgG in the autotransplanted patients. Splenectomized-only patients showed no significant increase in Ig levels in patients without splenic regrowth and partial improvement in patients with splenosis/accessory spleens. CONCLUSIONS: Considering this significant antipneumococcal antibody increase, spleen autotransplants can be expected to permit an adequate humoral response to pneumococcal infections and presumably also to other TI-2 antigens, and to protect against overwhelming postsplenectomy infection or sepsis.  (+info)

Paediatric, invasive pneumococcal disease in Switzerland, 1985-1994. Swiss Pneumococcal Study Group. (3/3096)

BACKGROUND: Cost effective use of new vaccines against pneumococcal disease in children requires detailed information about the local epidemiology of pneumococcal infections. METHODS: Data on 393 culture-confirmed cases of invasive pneumococcal infection in children (<17 years) hospitalized in Swiss paediatric clinics were collected retrospectively for the years 1985-1994. RESULTS: Meningitis (42%) was most frequent, followed by pneumonia (28%) and bacteraemia (26%). The overall annual incidence was 2.7 cases per 100000 children <17 years old and 11 cases per 100000 children <2 years old. Annual incidence rates were stable over the study period. Lethality was high for meningitis (8.6%) and bacteraemia (8.9%). A history of basal skull fracture was reported in 3.3% of children with pneumococcal meningitis. Residence in a rural region was associated with an increased risk of pneumococcal infection (relative risk = 1.45, 95% confidence interval: 1.01-2.00). CONCLUSIONS: Paediatric, invasive pneumococcal disease seems to be less frequent in Switzerland than in other European and non-European countries. This may be due to differences in diagnostic strategies and lower frequency of risk factors such as the use of day care. Children with a history of basal skull fracture are at increased risk for pneumococcal meningitis. Further investigation of the association of invasive pneumococcal infection with rural residence and the use of antibiotics for upper respiratory tract infections might give new insight into the dynamics of Streptococcus pneumoniae infection and the development of antibiotic resistance.  (+info)

Purification and cloning of a streptokinase from Streptococcus uberis. (4/3096)

A bovine plasminogen activator was purified from the culture supernatant of the bovine pathogen Streptococcus uberis NCTC 3858. After the final reverse-phase high-performance liquid chromatography step a single protein with a molecular mass of 32 kDa was detected in the active fraction. A partial peptide map was established, and degenerate primers were designed and used for amplification of fragments of the gene encoding the activator. Inverse PCR was subsequently used for obtaining the full-length gene. The S. uberis plasminogen activator gene (skc) encodes a protein consisting of 286 amino acids including a signal peptide of 25 amino acids. In an amino acid sequence comparison the cloned activator showed an identity of approximately 26% to the streptokinases isolated from Streptococcus equisimilis and Streptococcus pyogenes. Interestingly, the activator from S. uberis was found to lack the C-terminal domain possessed by the streptokinase from S. equisimilis. This is apparently a general feature of the streptokinases of this species; biochemical and genetic analysis of 10 additional strains of S. uberis revealed that 9 of these were highly similar to strain NCTC 3858. Sequencing of the skc gene from three of these strains indicated that the amino acid sequence of the protein is highly conserved within the species.  (+info)

Pathogenicity island 2 mutants of Salmonella typhimurium are efficient carriers for heterologous antigens and enable modulation of immune responses. (5/3096)

The potential use as vaccine delivery system of Salmonella typhimurium strains harboring defined mutations in the sseC (HH104) and sseD (MvP101) genes, which encode putative effector proteins of the type III secretion system of Salmonella pathogenicity island 2, was evaluated and compared with that of the well-characterized aroA mutant strain SL7207 by using beta-galactosidase (beta-Gal) as a model antigen. When orally administered to immune-competent or gamma interferon-deficient (IFN-gamma-/-) BALB/c mice, both mutants were found to be highly attenuated (50% lethal dose, >10(9) bacteria). Both strains were also able to efficiently colonize and persist in Peyer's patches. Immunization with HH104 and MvP101 triggered beta-Gal-specific serum and mucosal antibody responses equivalent to or stronger than those observed in SL7207-immunized mice. Although immunoglobulin G2 (IgG2) serum antibodies were dominant in all groups, IgG1 was also significantly increased in mice vaccinated with MvP101 and SL7207. Comparable beta-Gal-specific IgA and IgG antibodies were detected in intestinal lavages from mice immunized with the different strains. Antigen-specific CD4(+) T-helper cells were generated after vaccination with all vaccine prototypes; however, responses were significantly more efficient when HH104 and MvP101 were used (P < 0.05). Significantly higher levels of IFN-gamma were produced by restimulated spleen cells from mice immunized with HH104 than from those vaccinated with the MvP101 or SL7207 derivatives (P +info)

Transcutaneous immunization with bacterial ADP-ribosylating exotoxins as antigens and adjuvants. (6/3096)

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)

Functional activities and epitope specificity of human and murine antibodies against the class 4 outer membrane protein (Rmp) of Neisseria meningitidis. (7/3096)

Antibodies against the class 4 outer membrane protein (OMP) from Neisseria meningitidis have been purified from sera from vaccinees immunized with the Norwegian meningococcal group B outer membrane vesicle vaccine. The human sera and purified antibodies reacted strongly with the class 4 OMP in immunoblots, whereas experiments with whole bacteria showed only weak reactions, indicating that the antibodies mainly reacted with parts of the class 4 molecule that were not exposed. The purified human anti-class 4 OMP antibodies and the monoclonal antibodies (MAbs) were neither bactericidal nor opsonic against live meningococci. Three new MAbs against the class 4 OMP were generated and compared with other, previously described MAbs. Three linear epitopes in different regions of the class 4 OMP were identified by the reaction of MAbs with synthetic peptides. The MAbs showed no blocking effect on bactericidal activity of MAbs against other OMPs. However, one of the eight purified human anti-class 4 OMP antibody preparations, selected from immunoblot reactions among sera from 27 vaccinees, inhibited at high concentrations the bactericidal effect of a MAb against the class 1 OMP. However, these antibodies were not vaccine induced, as they were present also before vaccination. Therefore, this study gave no evidence that vaccination with a meningococcal outer membrane vesicle vaccine containing the class 4 OMP induces blocking antibodies. Our data indicated that the structure of class 4 OMP does not correspond to standard beta-barrel structures of integral OMPs and that no substantial portion of the OmpA-like C-terminal region of this protein is located at the surface of the outer membrane.  (+info)

Safety and immunogenicity of a Pseudomonas aeruginosa hybrid outer membrane protein F-I vaccine in human volunteers. (8/3096)

A hybrid protein [Met-Ala-(His)6OprF190-342-OprI21-83] consisting of the mature outer membrane protein I (OprI) and amino acids 190 to 342 of OprF of Pseudomonas aeruginosa was expressed in Escherichia coli and purified by Ni2+ chelate-affinity chromatography. After safety and pyrogenicity evaluations in animals, four groups of eight adult human volunteers were vaccinated intramuscularly three times at 4-week intervals and revaccinated 6 months later with either 500, 100, 50, or 20 microg of OprF-OprI adsorbed onto A1(OH)3. All vaccinations were well tolerated. After the first vaccination, a significant rise of antibody titers against P. aeruginosa OprF and OprI was measured in volunteers receiving the 100- or the 500-microg dose. After the second vaccination, significant antibody titers were measured for all groups. Elevated antibody titers against OprF and OprI could still be measured 6 months after the third vaccination. The capacity of the elicited antibodies to promote complement binding and opsonization could be demonstrated by a C1q-binding assay and by the in vitro opsonophagocytic uptake of P. aeruginosa bacteria. These data support the continued development of an OprF-OprI vaccine for use in humans.  (+info)

Poultry bacterial pathogens are mainly controlled by using high-cost sanitary measures and medical treatment. However, the drug-resistant strains of pathogens continuously emerge, and medical treatments are often ineffective. Moreover, there is increasing public objections to drug residues in poultry products. The other important type of control is the vaccination which depends on immunity. This immunological control is the major practical alternative to chemotherapy. Success of vaccines in combating poultry diseases depends mainly on the choice of the proper type of vaccines, correct time of its usage, and method of administration. The types of vaccines include attenuated live vaccines, and these vaccines were shown to be effective in inducing protection. The second type is killed vaccine or whole bacteria extracts which is less successful in providing protection compared to live vaccines. The metabolic product vaccine (toxoids) is the third type of vaccine. The recombinant DNA technique was adopted to

In addition to modern antigen-specific antibody- and vaccine-based immunologic cancer therapies, nonspecific immunotherapies with bacterial products have also shown antitumor effects (24-26). Over the past 2 decades, immunologic research has broadened our understanding of how these bacterial products may stimulate the immune system, and how endogenous mediators, induced by nonspecific immune stimulation influence the immune defense (22, 27, 28). In previous studies with MBV, also known as Coleys toxins, fever induction has been considered to be the key indicative aspect of successful treatment (29). However, there has been no systematic investigation of the mechanism by which MBV-induced fever would contribute to mediate tumor regression.. Therefore, a primary objective of our study was to identify the dose of standardized MBV that increased the body temperature from 38°C to 39.5°C. Eleven of 12 patients developed fever of ≥38°C at a given MBV dose level. The pyrogenic dose level varied ...

It has been nearly 20 years since the first Phase I clinical trial of a live-attenuated bacterial vaccine was created by recombinant DNA methods, opening the door to the use of these organisms as mucosal delivery vehicles for passenger antigens. Over this time, a number of animal studies have indicated the feasibility of this approach. These include studies showing that bacteria can deliver antigens expressed by the bacterium itself and that bacteria can deliver DNA vaccines to be expressed in target eukaryotic cells. Concomitant studies have identified a number of attenuating mutations that render the bacterial vectors both safe and immunogenic in humans. Both avenues of research indicate the significant promise of this approach to mucosal vaccine development; however, this promise remains largely unrealized at the level of human clinical trials. This review sketches the history of this problem and points toward possible solutions using Salmonella vaccine vectors as the prototypes.

Vickys son, who received 7 live virus and killed bacterial vaccines on one day in 1998, suffered nearly identical reactions as the daughter of Dr. and Mrs. Poling. During the interview, she said, I did something stupid. I gave my son 7 vaccines on one day. She went on to say I regret this but I cant take it back. Like Terry Poling, who was formerly a pediatric intensive care nurse, Dr. Debold recalls that she was a pediatric ICU nurse and completely trusted the vaccine recommendations by the CDC and AAP. Both Terry and Vicky fully vaccinated their children. Vicky, who is on NVICs Board, has served as NVICs Director of Patient Safety for the past few years and has counseled many parents reporting vaccine reactions and regression into poor health to NVIC during the past few years.

Summary of Facts and Submissions. I. European patent No. 0 790 835 (application No. 95939926.2, published as WO-A-96/14087) was granted with 8 claims. The patent relates to specific immunotherapy of cancer using a live recombinant bacterial vaccine vector.. II. Notice of opposition was filed by the opponent requesting the revocation of the European patent on the grounds of Article 100(a), (b) and (c) EPC. The opposition division revoked the patent on the grounds that the main and the auxiliary requests then on file did not fulfil the requirements of Article 56 EPC.. III. The opposition division considered the teaching of document D3 as the closest prior art. In its opinion, the problem underlying the patent in suit, namely the provision of an alternative tumour vaccine (main request) or the provision of an improved tumour vaccine (auxiliary request) had not been solved in an inventive manner.. IV. The patentee (appellant) filed an appeal against the decision of the opposition division.. V. In a ...
According to Minutes of the 15th Session (November 20-21, 1975) of the Panel of Review of Bacterial Vaccines and Toxoids with Standards and Potency (data presented by the US Bureau of Biologics, and the FDA):For several reasons, diphtheria toxoid, fluid or absorbed, is not as effective an immunizing agent as might be anticipated. Clinical (symptomatic) diphtheria may occur . . . in immunized individuals--even those whose immunization is reported as complete by recommended regimes . . . the permanence of immunity induced by the toxoid . . . is open to question.Medics have always known this vaccine doesnt work and have been writing about it since it was invented. For instance, in the Practitioner, April 1896, it was written that the serum did not, to any appreciable degree, prevent the extension of the disease to the larynx; all the severe cases died, and the good result in the lighter ones was attributable to the mild type of the epidemic. The doctor also states that, at the Hospital of ...

Advances in genomics and innovative strategies such as reverse vaccinology have changed the concepts and approaches to vaccine candidate selection and design. Genome mining and blind selection of novel antigens provide a novel route to investigate the mechanisms that underpin pathogenesis. The resulting lists of novel candidates are revealing new aspects of pathogenesis of target organisms, which in turn drives the rational design of optimal vaccine antigens. Here we use the discovery, characterization, and exploitation of fHbp, a vaccine candidate and key virulence factor of meningococcus, as an illustrative case in point. Applying genomic approaches to study both the pathogen and host will ultimately increase our fundamental understanding of pathogen biology, mechanisms responsible for the development of protective immunity, and guide next-generation vaccine design ...

How close are we to a vaccine for COVID-19? Take a look at the different vaccines under development, and where they are in the pipeline.
The coronavirus pandemic has set off an unprecedented global scramble for a vaccine. There are more than 100 potential vaccine candidates, according to the World Health Organization, but only eight have entered the crucial clinical trials stage. Four are in the United States and Europe, with the rest in China.
Oral vaccines which are intended for global use do not necessarily induce the same immune responses in all children worldwide. In fact, several vaccines often induce less frequent and lower mean antib

Recognition of bacteria by PRRs is a fundamental aspect of the innate immune response to pathogens. Impaired recognition can lead to severe illness and death. For example, mutations or TLR polymorphisms that affect the interaction of TLR with either agonists or signaling proteins have been associated with greatly increased susceptibility to infection in humans (reviewed in reference 59). We demonstrated previously that F. tularensis LVS is specifically recognized by TLR2 in HEK293T/TLR2 transfectants and in murine DC (8, 30) and that F. tularensis LVS infection induces in mice or their macrophages a very strong proinflammatory response as measured at the level of gene and protein expression (8). Thus, our demonstration herein that signaling through TLR2 is an obligatory component of the early macrophage response to F. tularensis LVS infection (Fig. 1) represents a key step forward in unraveling the potent proinflammatory response induced by this bacterium.. F. tularensis is an intracellular ...
In this study, we found that IL-6 is critical for resistance to primary LVS infection during either intradermal or intranasal LVS infection. IL-6 KO mice, and also wild-type mice treated with anti-IL-6 blocking antibodies, infected with LVS exhibited increased bacterial organ burdens and substantial bacteremia; ultimately, LVS infection results in death of IL-6 KO mice at much lower doses than for LVS-infected WT mice. An extensive search for a definitive mechanism by which IL-6 participates has not led to clear conclusions, however. The dramatic differences in survival were not reflected by obvious differences in blood chemistry, hematology, production of cytokines in infected tissues, or changes in proportions of splenic or blood leukocyte populations. While we did see an increase in AST/ALT levels, which may suggest liver distress, there were no significant differences in other markers of liver injury, such as creatinine kinase and lactate dehydrogenase (LDH), and there were no obvious ...
Author Summary Conventional treatment of bacterial infections typically includes administration of antibiotics. However, many pathogens have developed spontaneous resistance to commonly used antibiotics. Development of new compounds that stimulate the host immune system to directly kill bacteria by mechanisms different from those utilized by antibiotics may serve as effective alternatives to antibiotic therapy. In this report, we describe a novel compound capable of controlling infections mediated by different, unrelated bacteria via the induction of host derived reactive oxygen and reactive nitrogen species. This compound is comprised of cationic liposome DNA complexes (CLDC) and crude membrane preparations (MPF) obtained from attenuated Francisella tularensis Live Vaccine Strain (LVS). Pretreatment of primary mouse or human cells limited replication of virulent F. tularensis, Burkholderia pseudomallei, Yersinia pestis and Brucella abortus in vitro. CLDC+MPF was also effective for controlling lethal
Included studies compared injectable pneumococcal vaccines (polysaccharide, conjugate, or other type) with control (placebo or no vaccine) or another pneumococcal vaccine in adults with COPD. Primary outcomes were pneumonia, all-cause and respiratory-related mortality, and use of health care. Other outcomes included acute COPD exacerbation ...
Immunization(vaccination) can be discrete as active immunity formed by vaccine. It is resistance and immunologic retention corresponding to natural infection but deprived of risk of sickness. There are two rudimentary categories of vaccines: live attenuated and inactivated. Live attenuated vaccines are produced by altering a disease-producing virus or bacterium in a research laboratory. Vaccines derived from bacterium is called as bacterial vaccine and from virus is as viral vaccine. The subsequent vaccine organism retains the ability to duplicate and produce immunity, but generally does not cause illness. Inactivated vaccines can be self-possessed either by whole viruses or bacteria, or portions of either.. ...

In the case of natural whooping cough immunity, ACT or adenylate cyclase toxin, forms the basis of the initial immune response, and that front line immune response is crucial for removing the bacteria on reinfection. No vaccine can have ACT in it, because its made in the body, as part of the disease process and it seems vaccine manufacturers were not able to the whooping cough bacteria to excrete ACT in the vaccine substrates, because most articles which test recipients of the whole cell vaccine, find only low ACT antibodies. And the newer acellular whooping cough vaccine doesnt have ACT in it at all. The immunity created from an acellular vaccine misses this step out, and immunity from the old whole cell vaccine showed levels of ACT antibodies which were much much lower than that triggered by a natural infection..

An experimental vaccine to prevent human immunodeficiency virus (HIV) infection was designed by Mexican Max Medina Ramírez, a postdoctoral researcher at the Academic Medical Center of the University of Amsterdam in the Netherlands.. This candidate for HIV vaccine is capable of initiating broad spectrum neutralizing antibody precursors (bNAbs) against HIV. The vaccine candidate was developed using protein engineering techniques that allowed stabilizing the envelope of the HIV virus, also known as trimer -used by the virus to infect and, at the same time, circumvent the immune system.. In addition to the stabilization of the trime, the structure was modified to favor the activation of bNAb precursor B cells, which have the ability to prevent the spread of the virus.. This experimental vaccine was tested in several animal models and our results were published in the Journal of Experimental Medicine under the title Design and crystal structure of a native-like HIV-1 envelope trimer that engages ...

Preliminary studies with a variety of vaccines suggest target accessibility (potential immunogenicity) in a variety of solid tumors to immune directed approaches. In an effort to overcome limitations of immunostimulatory cancer vaccines, Gradalis has designed a novel autologous vaccine to address inability to fully identify cancer associated antigens, antigen recognition by the immune system (i.e. antigen--,immunogen), effector potency, and cancer-induced resistance. In an effort to overcome limitations of immunostimulatory cancer vaccines, we designed a novel dual-modulatory autologous whole cell vaccine, Vigil™, incorporating the rhGMCSF transgene and the bifunctional shRNAfurin (to block proprotein conversion to active TGFb1 and b2) to 1) address the inability to fully identify cancer associated antigens, 2) effect antigen recognition by the immune system, 3) enhance effector potency, and 4) subvert endogenous cancer-induced immune resistance.
