Provided herein are methods for the production of native and reconstituted hyaluronan (HA) complexes containing pentraxin-3 (PTX3) and heavy chain 1 (HC1) of inter alpha inhibitor (IαI). Compositions containing the complexes and therapeutic methods using the complexes are provided. Combinations and kits for use in practicing the methods also are provided.

The present invention provides soluble single wall nanotube (SWNT) constructs functionalized with a plurality of a targeting moiety and a plurality of one or more payload molecules attached thereto. The targeting moiety and the payload molecules may be attached to the soluble SWNT via a DNA or other oligomer platform attached to the SWNT. These soluble SWNT constructs may comprise a radionuclide or contrast agent and as such are effective as diagnostic and therapeutic agents. Methods provided herein are to diagnosing or locating a cancer, treating a cancer, eliciting an immune response against a cancer or delivering an anticancer drug in situ via an enzymatic nanofactory using the soluble SWNT constructs.

Systems and methods to increase the efficacy of vaccines that require or are rendered more effective with T cell mediated immunity are described. The systems and methods utilize polynucleotides that genetically modify T cells to express a T cell receptor specific for an administered vaccine antigen.

The present invention provides a nanogel nasal vaccine that induces cell-mediated immunity. The present invention relates to a vaccine preparation comprising a complex of a nanogel, a vaccine antigen, and an adjuvant, wherein the vaccine preparation can efficiently induce the cell-mediated immunity, and can also induce a systemic and mucosal immune response.

The present disclosure relates to a nanoparticle compound, including: a hydrophilic polymer, a linker, and a drug, wherein the drug is linked to the hydrophilic polymer by the linker, wherein the drug is mithramycin A or a derivative thereof, and wherein the linker is boronic acid or a boronic acid derivative. For example, the present disclosure includes one or more nanoparticles including one or more conjugates, and methods of using the nanoparticles for drug delivery, and treating a disease such as Ewing sarcoma or osteosarcoma.

The present invention concerns improved methods and compositions for preparing SN-38 conjugates of proteins or peptides, preferably immunoconjugates of antibodies or antigen-binding antibody fragments. More preferably, the SN-38 is attached to the antibody or antibody fragment using a CL2A linker, with 1-12, more preferably 6-8, alternatively 1-5 SN-38 moieties per antibody or antibody fragment. Most preferably, the immunoconjugate is prepared in large scale batches, with various modifications to the reaction scheme disclosed herein to optimize yield and recovery in large scale. Other embodiments concern optimized dosages and/or schedules of administration of immunoconjugate to maximize efficacy for disease treatment and minimize side effects of administration.

The invention provides a composition and pharmaceutical formulation including a peptide immobilized in a hydrogel. Compositions and formulations of the invention are useful in reducing the size, severity or duration of a wound, ameliorating of one or more symptoms associated with a wound without necessarily curing the wound or lessening in the growth or severity of a wound, skin irritation or skin inflammation. Compositions and formulations of the invention are particularly useful in the treatment of skin irritation, skin inflammation, and a wound associated with diabetes, such as a diabetic ulcer.

A combination therapy involving different therapeutic molecules can enhance and improve the therapeutic potentials. An effective therapeutic strategy conjugates silica (SiO.sub.2) nanoparticles with, e.g., 3-glycidyloxypropyl, trimethoxysilane and azoles, e.g., 1,2,4-triazole (Tri), 3-aminotriazole (ATri), 5-aminetetrazole (Atet), imidazole (Imi). These exemplary materials—classified as SiO.sub.2-3GPS-Tri (Conj. 1), SiO.sub.2-3GPS-Atri (Conj. 2), SiO.sub.2-3GPS-Atet (Conj. 3), SiO.sub.2-3GPS-Btri (Conj. 4), and SiO.sub.2-3GPS-Imi (Conj. 5)—can amplify targeting of therapeutics for human colorectal carcinoma cells (HCT-116), enhancing anti-cancer effects.

Described herein is a nanoparticle system including a multivalent nanoparticle core having a plurality of β-hairpin peptides conjugated thereto. Also included are pharmaceutical compositions and methods of making the nanoparticle system. Further included are immunotherapy methods including administering the nanoparticle system to a subject in need thereof, such as a human cancer patient.

Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by application of an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.
