摘要:
Hybrid molecules comprising CD4 minimal modules or mimetics that bind to HIV Env polypeptides in combination with one or more HIV Tat polypeptides are described. Also described are complexes of these hybrid molecules with Env as well as methods of diagnosis, treatment and prevention using the polynucleotides and polypeptides.
摘要:
The invention provides proteins from Neisseria meningitidis, including the amino acid sequences and the corresponding nucleotide sequences. The proteins are predicted to be useful antigens for vaccines and/or diagnostics.
摘要:
Immunogenic compositions (e.g. vaccines) comprising: (a) an immunostimulating amount of a Neisseria antigen (preferably N. meningitidis serogroup B); and (b) an immunostimulating amount of an adjuvant composition comprising an oligonucleotide comprising at least one CG motif. Component (b) may further comprise a second adjuvant. Component (a) may be selected from a variety of antigens. Adjuvant compositions comprising an oligonucleotide having at least one CG motif, and complete Freund's adjuvant (CFA) are also provided.

摘要:
While oil-in-water emulsions are excellent adjuvants for influenza vaccines, their efficacy can be improved by additionally including other immunostimulating agent(s) to improve cytokine responses, such as γ-interferon response. Thus, a vaccine comprises (i) an influenza virus antigen; (ii) an oil-in-water emulsion adjuvant; and (iii) a cytokine-inducing agent.
摘要:
HIV antigens are mucosally administered in one or more priming immunization(s), and then HIV antigens are parenterally administered in one or more boosting immunization(s). Thus the invention provides a method for raising an immune response in a patient, comprising: (i) administering a HIV antigen to the patient via a mucosal route; and then (ii) administering a HIV antigen to the patient via a parenteral route. The antigens will typically be adjuvanted. Preferred mucosal immunizations are via the intranasal route using a detoxified mutant of E. coli heat labile toxin as the adjuvant. Preferred parenteral immunizations are via the intramuscular route using an oil-in-water emulsion adjuvant.
摘要:
If pathogen factors such as meningococcal NMB 1870 or flaviviral NS1 are able to sequester factor H in the blood then its inhibitory effect on complement may be disturbed, thereby permitting C3 to initiate a dramatic attack on host endothelial tissue. In combination with a strong inflammatory response, this attack can result in sever damage to the endothelium, with resulting hemorrhagic syndrome. Blocking the interaction between pathogen factors and factor H may thus be used to treat and/or prevent these pathogen-induced hemorrhagic syndromes. The interaction may, for instance, be blocked by antibodies, either delivered endogenously (passive immunisation) or produced by a patient's immune system (active immunisation).
摘要:
The invention provides proteins from Neisseria meningitidis (strains A & B), including amino acid sequences, the corresponding nucleotide sequences, expression data, and serological data. The proteins are useful antigens for vaccines, immunogenic compositions, and/or diagnostics.
摘要:
This invention provides polynucleotides encoding Helicobacter pylori cytotoxin associated immunodominant antigen. The polynucleotides can be used as probes to identify the presence of complementary target nucleotide sequences. The invention also provides kits and vectors containing the polynucleotides of the invention.
摘要:
An 85 kDa antigen from Neisseria meningitidis and Neisseria gonorrhoeae has been cloned, sequenced and expressed. The antigen is common to diverse strains, serogroups and serotypes of N. meningitidis, and also to N. gonorrhoeae, N. polysaccharia and N. lactamica. The protein sequences of N. meningitidis (serogroups A and B) and N. gonorrhoeae are highly homologous.
