The disclosure relates generally to alpha polyglutamated pralatrexate, formulations containing liposomes filled with alpha polyglutamated pralatrexate, methods of making the alpha polyglutamated pralatrexate and liposome containing formulations, and methods of using polyglutamated alpha polyglutamated pralatrexate and liposome containing formulations to treat hyperproliferative disorders (e.g., cancer) and disorders of the immune system (e.g., an autoimmune disease such as rheumatoid arthritis).

Provided are aromatic compounds, phospholipid-polymer-aromatic conjugates comprising the aromatic compounds, and liposome compositions including the phospholipid-polymer-aromatic conjugates. The liposomal compositions may be useful for imaging of Alzheimer's Disease, for example, imaging of the amyloid- plaque deposits characteristic of Alzheimer's Disease.

Carbohydrate functionalized catanionic vesicles that include a glycoconjugate and/or peptidoconjugate for vaccination or drug delivery, methods for forming these, and methods of using these.

The present invention relates to a drug delivery vehicle comprising a polydiacetylene liposome, wherein a lipid bilayer is formed by a mixture of 10,12-pentacosadiynoic acid (PCDA), 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), and N-palmitoyl homocysteine (PHC), and a drug to be delivered is encapsulated in an isolated inner space of a polydiacetylene liposome. The PDA liposome drug delivery vehicle of the present invention comprises a lipid layer formed by mixing different phospholipids, excluding polydiacetylene, so as to be stable, and thus any leakage problems of an encapsulated drug are eliminated. In addition, since the liposome is sensitive to a pH, the shape and size thereof can be readily changed through the formation of a liposome-liposome conjugate by the improved sensitivity of the drug delivery vehicle under a specific acidic requirement, thereby enabling selective drug release, and thus can be applied as a drug delivery vehicle for various target materials. Additionally, the release of a drug can be controlled by controlling a pH requirement of the surroundings, and a drug release process can be monitored in real time through the fluorescence expressed by the stimulation to the surroundings.

The present invention relates to a composition comprising liposomes, wherein the liposomes preferably comprise phospholipids, magnetic nanoparticles, an imaging agent and an imaging label, and at least one active agent. The liposomes are capable of releasing the at least one active agent into a target environment by the concomitant action of a phospholipase that is able to degrade at least one of said one or more phospholipids and an alternating magnetic field.

Advancements in solid tumor (e.g., renal cell carcinoma) treatments and imaging are described. The advancements are based on nanoformulations that: (i) overcome deliverability issues associated with anti-cancer compounds; (ii) have increased targeted delivery to tumors, and hypoxic cores of tumors due to the presence of targeting ligands; (iii) have increased delivery to the hypoxic cores of tumors due to engineered shapes; (iv) provide synergistic treatment combinations; and/or (v) overcome cancer cell resistance to therapeutic treatments.

Microvesicles play essential roles in disease progression. The present invention provides a novel microvesicle membrane protein and application thereof. Disclosed is method comprises phosphorylated CSE1L (cellular apoptosis susceptibility protein)- or CSE1L-binging agents for microvesicle isolation, analysis, or binding for disease diagnosis.

Provided are aromatic compounds, phospholipid-polymer-aromatic conjugates comprising the aromatic compounds, and liposome compositions including the phospholipid-polymer-aromatic conjugates. The liposomal compositions may be useful for imaging of Alzheimer's Disease, for example, imaging of the amyloid- plaque deposits characteristic of Alzheimer's Disease.

The present invention provides nanoparticles or conjugates comprising at least one ligand that selectively targets major facilitator superfamily domain-containing protein-2a (MFSD2A). In various embodiments, the nanoparticles or conjugates of the invention target at least one cell comprising MFSD2A (e.g., endothelial cells of blood brain barrier). In some embodiments, the nanoparticles or conjugates of the invention cross the blood brain barrier and/or blood retinal barrier. In other aspects, the present invention relates to methods for in vivo delivery of diagnostic and/or therapeutic agents to a brain. In other aspects, the present invention relates to methods of preventing or treating a neurological or cognitive disease or disorder using the nanoparticles or conjugates of the invention.

A pharmaceutical composition is provided comprising a vitamin E derivative, an anionic phopholipid-binding protein, an anionic phospholipid and a sterol. Also provided is a method for preparing a composition for delivering a cargo to a subject comprising a) forming liposomes from a vitamin E derivative, an anionic phospholipid-binding protein such as annexin, an anionic phospholipid such as phosphatidylserine and a sterol; and b) encapsulating the cargo in the liposomal composition.
