Abstract: 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.

Abstract: Disclosed are particles for delivering cytokinese, such as IL-12, for the treatment of cancer. The particles comprise cytokines non-covalently bound to liposomes, where the liposomes are coated with polyelectrolytes.

Abstract: The disclosure features amphiphilic ligand conjugates comprising a chimeric antigen receptor (CAR)ligand and a lipid. The disclosure also features compositions and methods of using the same, for example, to stimulate proliferation of CAR expressing cells.

Abstract: The present disclosure relates to synthetic oncolytic viruses comprising a lipid nanoparticle comprising one or more types of lipid and a self-amplifying replicon RNA comprising a sequence that encodes an immunomodulatory molecule.

Abstract: What is disclosed is a vaccine comprising an immunogen conjugated to an albumin-binding polymer-lipid tail, wherein the vaccine is suitable for transmucosal (e.g, intranasal) administration. Also disclosed is a method of using the vaccine to immunize a subject by transmucosal (e.g, intranasal) administration of an effective amount of the vaccine, alone or with an adjuvant.

Abstract: The present disclosure relates generally to technologies comprising engineered immune cells that express chimeric antigen receptors (CARs) that specifically bind to a membrane-inserting amphiphilic ligand. Also disclosed herein are methods and compositions for treating a tumor.

Abstract: The present disclosure provides immunomodulatory fusion proteins-metal hydroxide complexes comprising an immunomodulatory domain adsorbed to a metal hydroxide via ligand exchange. The disclosure also features compositions and methods of using the same, for example, to treat cancer.

Abstract: The present disclosure provides compositions and methods for efficient and effective protein delivery in vitro and in vivo. In some aspects, proteins are reversibly crosslinked to each other and/or modified with functional groups and protected from protease degradation by a polymer-based or silica-based nanoshell.

Abstract: The present invention provides a conjugate comprising an albumin binding peptide and a cargo, compositions for directing cargos to the lymphatic system, and vaccines. The methods of the invention can be used to increase an immune response, or to treat cancer or an infectious disease.

Abstract: The present disclosure relates to synthetic oncolytic viruses comprising a lipid nanoparticle comprising one or more types of lipid and a self-amplifying replicon RNA comprising a sequence that encodes an immunomodulatory molecule.

Abstract: The present disclosure relates to a device, comprising a base and a plurality of microneedles attached to the base, wherein each microneedle has an outer surface; the outer surface of at least one microneedle being coated with a composition comprising at least one polymer and least one Peptide Nucleic Acid (PNA). The present disclosure additionally relates to a method of detecting an analyte in interstitial fluid (ISF), comprising contacting the device to a subject, for example, to human skin.

Abstract: Disclosed are particles for delivering cytokinese, such as IL-12, for the treatment of cancer. The particles comprise cytokines non-covalently bound to liposomes, where the liposomes are coated with polyelectrolytes.

Abstract: Non-liposome, non-micelle particles formed of a lipid, an additional adjuvant such as a TLR4 agonist, a sterol, and a saponin are provided. The particles are porous, cage-like nanoparticles, also referred to as nanocages, and are typically between about 30 nm and about 60 nm. In some embodiments, the nanocages include or are administered in combination with an antigen. The particles can increase immune responses and are particularly useful as adjuvants in vaccine applications and related methods of treatment. Preferred lipids, additional adjuvants including TLR4 agonists, sterols, and saponins, methods of making the nanocages, and method of using them are also provided.

Abstract: The present disclosure provides lipid compositions comprising lipid particles (e.g., lipid nanodiscs), wherein the lipid particles (e.g., lipid nanodiscs) comprise a STING agonist amphiphile conjugate, a phospholipid and a PEG-lipid. The compositions are used in methods to induce or promote immune responses, such as immune responses useful for the treatment of cancer or infectious disease.
