摘要:
Vaccines are disclosed against parasites. The vaccines include peptides in an immunological composition. In particular, the parasite is Toxoplas gondii.
摘要:
Pharmaceutical and vaccine compositions comprise recombinant hemagglutinin from a pre-pandemic or pandemic influenza virus and an adjuvant comprising GLA. A particularly relevant pre-pandemic influenza virus is H5N1. Kits and methods of using the compositions are also provided.
摘要:
Compounds and methods are provided for diagnosing, preventing, treating and detecting leishmaniasis infection and stimulating immune responses in patients are disclosed. The compounds disclosed are include polypeptides and fusion proteins that contain at least one immunogenic portion of one or more Leishmania antigens, or a variant thereof. Additionally, methods of screening a screening library for tandem repeat proteins that have immunogenic properties are disclosed. Vaccines and pharmaceutical compositions comprising polynucleotides, polypeptides, fusion proteins and variants thereof that may be used for the prevention and therapy of leishmaniasis, as well as for the detection of Leishmaniasis infection are described.
摘要:
The present invention provides rapid diagnostic assays for the detection of Leishmania which can readily be used in the field, leading to more rapid treatment. In certain embodiments, the inventive assays, including ELISA and lateral flow assays, employ antibodies that may be effectively employed to detect the Leishmania major antigen TSA, which is present in both promastigotes grown in culture and in amastigotes. Such assays may be employed to detect the presence of cutaneous leishmaniasis in a subject using scrapings, biopsies, and/or aspirates taken from cutaneous lesions.
摘要:
Compositions and methods, including vaccines and pharmaceutical compositions for inducing or enhancing an immune response are disclosed based on the discovery of useful immunological adjuvant properties in a synthetic, glucopyranosyl lipid adjuvant (GLA) that is provided in substantially homogeneous form. Chemically defined, synthetic GLA offers a consistent vaccine component from lot to lot without the fluctuations in contaminants or activity that compromise natural-product adjuvants. Also provided are vaccines and pharmaceutical compositions that include GLA and one or more of an antigen, a Toll-like receptor (TLR) agonist, a co-adjuvant and a carrier such as a pharmaceutical carrier.
摘要:
Compositions comprising fusion polypeptides of T. cruzi epitopes are provided, together with methods for the use of such compositions in the diagnosis of T. cruzi infection and in screening blood supplies. Diagnostic kits comprising such compositions are also provided.
摘要:
The present invention relates generally to a fusion protein made from a synthetic gene construct comprising of elements derived from the Leishmania antigens K26, K39, and K9. The fusion protein is particularly useful in the diagnosis of leishmaniasis, particularly visceral leishmaniasis in animals such as humans and dogs.
摘要:
Compounds and methods for the diagnosis and treatment of B. microti infection are disclosed. The compounds provided include polypeptides that contain at least one antigenic portion of a B. microti antigen and DNA sequences encoding such polypeptides. Antigenic epitopes of such antigens are also provided, together with pharmaceutical compositions and vaccines comprising such polypeptides, DNA sequences or antigenic epitopes. Diagnostic kits containing such polypeptides, DNA sequences or antigenic epitopes and a suitable detection reagent may be used for the detection of B. microti infection in patients and biological samples. Antibodies directed against such polypeptides and antigenic epitopes are also provided.
摘要:
Compounds and methods for treating lung cancer are provided. The inventive compounds include polypeptides containing at least a portion of a lung tumor protein. Vaccines and pharmaceutical compositions for immunotherapy of lung cancer comprising such polypeptides, or DNA molecules encoding such polypeptides, are also provided, together with DNA molecules for preparing the inventive polypeptides.
摘要:
Methods for eliciting or enhancing immune responses to antigens, including tumor antigens, and/or DNA vaccines are provided. The methods employ polypeptides or nucleic acid compositions that contain at least a biologically active portion of a Leishmania braziliensis or Leishmania major homologue of the eukaryotic initiation factor 4A, or a variant thereof. Such polypeptides and compositions are useful for enhancing or eliciting a patient's cellular and/or humoral immune response, for instance within methods for treating tumors.
