Disclosed herein are conjugates including a fatty acid, a self-assembly domain, and a polypeptide having phase transition behavior. Further disclosed are methods of using the conjugates to treat disease, methods of delivering an agent, and methods of preparing the conjugates.

A preparation method of adiposomes, and use thereof. Provided is a method for preparing adiposomes consisting of neutral lipids and a monolayer phospholipid membrane, comprising a1) vortexing phospholipid and neutral lipids in a buffer, centrifuging the resulting mixture, and collecting an upper liquid phase; a2) purifying the upper liquid phase twice or more by uniformly mixing the upper liquid phase with the buffer, layering the mixture, and collecting an upper liquid phase; and a3) uniformly mixing the upper liquid phase obtained in step a2) with the buffer, layering the mixture, and collecting a lower liquid phase in containing adiposomes. For the adiposomes prepared by the method, one or more resident proteins and/or functional proteins can be recruited to obtain artificial lipid droplets, and one or more apolipoproteins can be recruited to obtain artificial lipoproteins; and they all play important roles in preparing drugs and/or drug carriers.

The present invention relates to nanoparticles associated with (e.g., complexed, conjugated, encapsulated, absorbed, adsorbed, admixed) biomacromolecule agents configured for treating, preventing or ameliorating various types of disorders, and methods of synthesizing the same. In particular, the present invention is directed to compositions comprising nanoparticles (e.g., synthetic high density lipoprotein (sHDL)) associated with (e.g., complexed, conjugated, encapsulated, absorbed, adsorbed, admixed) biomacromolecule agents (e.g., nucleic acid, peptides, glycolipids, etc.), methods for synthesizing such nanoparticles, as well as systems and methods utilizing such nanoparticles (e.g., in diagnostic and/or therapeutic settings).

Methods of loading extracellular vesicles with payload molecules via homogenization are disclosed herein.

The present invention relates to a pulmonary surfactant-based anticancer drug. The anticancer drug encapsulated in a liposome made of a pulmonary surfactant can effectively target lung cancer cells, especially adenocarcinomas derived from type II alveolar cells, and has low toxicity and excellent structural stability.

Therapeutic modalities are provided for targeting adoptive cellular therapies to specific sites of disease, involving the use of specific repertoirs of PRR ligands. In effect, innate immune system signaling is provoked so as to facilitate the homing of adoptive immune cells to sites of disease, for example to the site of a solid tumor.

Disclosed herein are high-density lipoprotein-like nanoparticles (HDL-NP) having a soft material core (e.g., a lipid-conjugated inorganic core) associated with hydrophobic therapeutic agents. In some embodiments, the HDL-NPs are targeted to scavenger receptor type B1 (SR-B1). In some embodiments, the hydrophobic therapeutic agents are chemotherapeutic agents. Also disclosed herein are methods for treating disorders such as cancer with the HDL-NPs.

The present disclosure relates to a method of loading a toll like receptor (TLR)7/8 agonist into a liposome using remote loading and a kit of parts suitable for the loading of a TLR7/8 agonist into a liposome by said method. The present disclosure further relates to a liposome comprising a salt of a TLR7/8 agonist in the liposome interior and to the use of said liposome for stimulation of an immune response and/or treatment of a clinical condition. Finally, the present disclosure relates to a TLR7/8 agonist which is suitable for being remotely loaded into a liposome.

A recombinant SARS-CoV-2 S glycoprotein ectodomain trimer is disclosed, including three recombinant protomers each containing at least the SARS-CoV-2 S glycoprotein ectodomain, and wherein: in each protomer, the furin cleavage site is inactivated/disrupted; Arg408 of one of the protomers is covalently linked to Lys378 of another one of the protomers; and Lys947 of one of the protomers is covalently linked to Arg1019 and/or to Lys776 of another one of the protomers.

Described herein is the formulation of immunogenic or vaccine compositions comprising neutral lipid liposome based adjuvants, where the composition is suitable for lyophilisation. In particular, the invention relates to lyophilised forms of such immunogenic or vaccine compositions wherein both the immunogen or vaccine antigen and the adjuvant are present in one and the same vial, as well as to the formulation and manufacture of lyophilised forms of such immunogenic or vaccine composition.
