摘要： Compositions and methods are described for inducing an immune response against an immunogen in humans. The induced immune response is obtained by administering a heterologous prime-boost combination of an in vitro transcribed (IVT) self-replicating RNA (repRNA) and an adenovirus vector. The compositions and methods can be used to provide a protective immunity against a disease, such as a viral infection or a cancer, in humans.

摘要： Compositions containing a nucleic acid nanostructure having a desired geometric shape and antigens bound to its surface are provided. The nanostructures can be, for example, in the form of a 6-helix bundle or icosahedron. The nanostructure design allows for control of the relative position and/or stoichiometry of the antigen bound to its surface. The antigens displayed on the nanostructure surface are arranged with the preferred number, spacing, and 3D organization to elicit a robust immune response. The displayed antigen can be an HIV immunogen such as eOD-GT6, eOD-GT8, or variants thereof. The compositions may thus be useful as immunogens, vaccines, immunostimulators, adjuvants, and the like. Methods of inducing immune responses, inducing protective immunity, inducing the production of neutralizing antibodies or inhibitory antibodies, inducing tolerance, and treating cancer, infectious or autoimmune diseases are also provided.

摘要： Lipid conjugates for enhanced delivery of cargo to the lymph nodes are disclosed. The lipid conjugates typically include three domains: a lipophilic domain that binds to albumin, a polar block domain, and a cargo such as a molecular adjuvant or immunostimulatory compound (such as an oligonucleotide) or antigenic peptide. Depending on the cargo, the length and compositions of the polar block can be tailored to push the equilibrium toward albumin binding, stable micelle formation, or cell insertion. The conjugates can be administered to a subject, for example, a subject with cancer or an infection, to induce or enhance a robust immune response in the subject.

摘要： Immunization methods are provided. The methods typically include administering the subject an effective amount of an antigen and adjuvant to induce an immune response against an antigen, the method including two or more of (i) slow prime delivery of antigen and/or adjuvant, a (ii) temporally delayed 2nd immunization, and (iii) a robust adjuvant. Element (i) can be or include temporally extended exposure of antigen, adjuvant, or preferably the combination thereof, such as one or more of repeated administrations, infusion optionally by osmotic pump and escalating dosing. Element (ii) can include administering one or more boost doses of antigen and/or adjuvant, for example between 11 and 35 weeks after the start of the prime administration. A preferred robust adjuvant (iii) is one including non-liposome, non-micelle particles formed of a lipid, an additional adjuvant such as a TLR4 agonist, a sterol, and a saponin.

摘要： Compositions containing a nucleic acid nanostructure having a desired geometric shape and immunostimulatory agent(s) bound to its surface are provided. The nanostructures can be, for example, in the form of a 6-helix bundle, or icosahedron, or a pentagonal bipyramid. The nanostructure design allows for control of the relative position and/or stoichiometry of the immunostimulatory agent(s) bound to its surface. The immunostimulatory agent(s) displayed on the nanostructure surface are arranged with the preferred number, spacing, and 3D organization to elicit a robust immune response. The displayed antigen can be a TLR agonist, such as a TLR9 agonist. The immunostimulatory compositions may thus be useful as immunogens, vaccines, adjuvants, and the like. Methods of inducing immune responses, and for targeted induction of TLR activation are also provided.
