Compositions that include at least a portion of at least one pathogen-associated molecular pattern and at least a portion of at least one member selected from the group consisting of a Den1 viral envelope protein, a Den2 viral envelope protein, a Den3 viral envelope protein and a Den4 viral envelope protein are employed in methods to stimulate a protective immune response in a subject.

Methods of stimulating immunity employing dengue viral antigens

Methods of stimulating protective immunity employing Dengue viral antigens

Compositions that include at least a portion of a flagellin and an antigen can be employed in methods that stimulate an immune response in a subject, in particular, a protective immune response in a subject. Compositions can be associated with particles and employed in the methods in relatively low doses to provide protective immunity to infection.

Deletion mutants of flagellin and methods of use

Compositions that include Toll-like Receptor 5 agonists and at least a portion of at least one viral antigen can be employed in methods that stimulate an immune response in a subject, in particular, a protective immune response in a subject. Compositions can be associated with particles and employed in the methods in relatively low doses to provide protective immunity to viral infection.

Methods of making a protein that stimulates a protective immune response in a subject include separating a portion of a protein from a naturally occurring influenza viral hemagglutinin to form a protein portion.

Flagellin fusion proteins

Methods of making a protein that stimulates a protective immune response in a subject include separating a portion of a protein from a naturally occurring influenza viral hemagglutinin to form a protein portion. The protein portion includes at least a portion of a globular head, and at least a portion of at least one secondary structure having at least one &#x3b2;-sheet at a bottom of the globular head that causes the globular head to essentially retain its tertiary structure. The protein portion made by the methods of the invention lacks a transmembrane domain, a cytoplasmic domain and an HA2 subunit. A nucleic acid sequence encoding the protein portion is transformed into a prokaryotic host cell.

Methods of making hemagglutinin proteins

Methods that stimulate a protective immune response in a subject include a portion of a protein from a naturally occurring viral hemagglutinin, wherein the protein portion includes at least a portion of a globular head and at least a portion of at least one secondary structure that causes the globular head to essentially retain its tertiary structure, and wherein the protein portion lacks a transmembrane domain, a cytoplasmic domain and an HA2 subunit. Compositions administered to the subject can further include a carrier and can be administered in single or multiple doses.

Methods of treatment with compositions that include hemagglutinin

Compositions that include a fusion protein comprising flagellin and at least one antigen that has an isoelectric point greater than about 7.0 and that is fused to at least one domain 3 of the flagellin activate Toll-like Receptor 5. Methods of stimulating an immune response, in particular, a protective immune response include administering a composition that includes an antigen fused to a loop of domain 3 of flagellin.

Fusion proteins and methods of use

Fusion proteins comprise at least a portion of at least one flagellin and at least a portion of at least one Dengue viral envelope protein. The fusion proteins are used to stimulate an immune response and protective immunity in a subject.

Fusion proteins comprising flagellin and dengue viral envelope proteins

Methods of making and compositions that stimulate a protective immune response in a subject include a portion of a protein from a naturally occurring viral hemagglutinin, wherein the protein portion includes at least a portion of a globular head and at least a portion of at least one secondary structure that causes the globular head to essentially retain its tertiary structure, and wherein the protein portion lacks a membrane fusion domain, a transmembrane domain and a cytoplasmic domain. Compositions can further include a Toll-like Receptor agonist and a carrier protein.
