Abstract: The invention relates to pharmaceutical compositions comprising at least one antigen and an adjuvant composition, where the adjuvant composition comprises a saponin and a liposome. The liposome of the composition comprises monophosphoryl lipid A (MPLA), cholesterol and a phospholipid that is in a liquid crystalline state at greater than or equal to 23° C., and the concentration of cholesterol to lipid in the liposome is greater than 50% (mol/mol). The antigen in the composition is a soluble Plasmodium falciparum recombinant circumsporozoite protein (rCSP) comprising the amino acid sequence of SEQ ID NO:1, or a P. falciparum rCSP peptide that is at least 95% identical to the amino acid sequence of SEQ ID NO:1.

Abstract: The disclosure generally provides recombinant proteins comprising Tobamovirus capsid proteins and an immunogenic epitope of an antigen of interest. The recombinant protein can be used to assemble an array comprising a plurality of associated recombinant proteins that can enhance the immunogenicity of the epitope and induce and/or enhance an immune response to the antigen. The disclosure also provides compositions, such as vaccines, that include the recombinant protein as well as methods for inducing and/or enhancing an immune response in a mammal.

Abstract: Disclosed are AMA-1 immunogenic peptides and epitopes, nucleotide sequences encoding the peptides and epitopes, compositions, and vaccines including the peptides and/or epitopes. Antibodies that specifically bind to AMA-1 and the AMA-1 epitopes and immunogenic peptides disclosed herein are also provided. The disclosure provides for expression vectors, host cells, and methods for making the polypeptides and antibodies. Also provided are methods of treatment, prevention, vaccination, and/or immunization of a subject against malaria and the clinical indications associated with malaria.

Abstract: The present invention provides novel nucleotide sequence and other constructs used for expression of novel recombinant P. falciparum circumsporozoite proteins in bacterial cells such as E. coli. Processes are provided for producing a soluble recombinant P. falciparum CSP from E. coli. Methods to produce a human-grade, highly immunogenic anti-malaria vaccine based on CSP are shown. The novel recombinant P. falciparum circumsporozoite protein by itself or in combination with other malaria antigens or adjuvants can form the basis of an effective malaria vaccine.

Abstract: In this application is the expression and purification of a recombinant Plasmodium vivax (SalI) PvMSP-1 p42. The method of the present invention produces a highly purified protein which retains folding and disulfide bridging of the native molecule. The recombinant PvMSP-1 p42 is useful as a diagnostic reagent, for use in antibody production, and as a vaccine.

Abstract: In this application is described the expression and purification of a recombinant Plasmodium falciparum (3D7) AMA-1 ectodomain. The method of the present invention produces a highly purified protein which retains folding and disulfide bridging of the native molecule. The recombinant AMA-1 is useful as a diagnostic reagent, for use in antibody production, and as a protein for use alone, or as part of, a vaccine to prevent malaria.

Abstract: In this application is described a method for determining the presence or absence of functional anti-AMA-1 invasion-inhibitory antibodies in a sample. This method can serve as a correlate for immunity of a P. falciparum AMA-1-based vaccine or as a correlate for immunity to P. falciparum by natural exposure if that immunity was induced by invasion inhibitory antibodies against the AMA-1 protein.
