  • Publication number: 20200268678
    Abstract: Disclosed herein are nanoparticles comprising a lipid core comprising a sterol; and a complex comprising a cationic agent and a therapeutic agent, wherein the complex is encapsulated within the lipid core. Methods to produce the nanoparticle comprise: combining a cationic agent, a therapeutic agent, and a first water-immiscible solvent with a first aqueous solution, thereby forming a mixture comprising a complex comprising the cationic agent and the therapeutic agent; combining the mixture with a second waterim-miscible solvent, thereby forming an aqueous phase and an organic phase, and separating the organic phase comprising the complex; combining the organic phase comprising the complex with a sterol and a first water-miscible organic solvent; and dispersing the complex in a second aqueous solution to form a herein disclosed nanoparticle. Methods for treating a disease and for reducing nanoparticle burst rate are also disclosed.

  • Patent number: 7588764
    Abstract: Non-denatured, recombinant human immunodeficiency virus (HIV) Tat that is free of bacterial RNA and endotoxin is employed in an anti-HIV vaccine. A process of producing the recombinant Tat protein includes steps for removing bacterial RNA from the recombinant Tat and for removing endotoxin from the recombinant Tat protein. A Tat-adsorbed nanoparticle formulation and method of making the same. A method of vaccinating against and/or treating HIV infection comprises administering to a subject in need of such vaccination or treatment an immune-response inducing effective amount of the recombinant Tat protein.
