Nucleic acids are prepared by dissolving compounds containing them in a suitable solvent or solvent system and forming microspheres from the resulting solution. The microspheres are administered to an individual as protection from conditions where delivery of nucleic acids is useful, such as in treatment of autoimmune disease.

Nucleic acid microspheres, production and delivery thereof

AS-oligonucleotides are delivered in microsphere form in order to induce dendritic cell tolerance, particularly in the non-obese-diabetic (NOD) mouse model. The microspheres incorporate antisense (AS) oligonucleotides. A process includes using an antisense approach to prevent an autoimmune diabetes condition in NOD mice in vivo and in situ. The oligonucleotides are targeted to bind to primary transcripts CD40, CD80, CD86 and their combinations.

Delivery of AS-oligonucleotide microspheres to induce dendritic cell tolerance for the treatment of autoimmune type 1 diabetes

The present invention relates to compositions of methods of making and compositions small compositions of particles of an active agent. In accordance with the method of production, the active agent is dissolved in an aqueous or aqueous-miscible solvent containing a dissolved phase-separation enhancing agent (PSEA) to form a solution in a single liquid phase. The solution is subjected to a liquid-solid phase separation to cause the active agent to form small spherical that are substantially amorphous or non-crystalline and are injectable through fine gauge needles at high concentrations. The invention has special application for higher molecular weight proteins.

Protein microspheres having injectable properties at high concentrations

Nucleic acids are prepared by dissolving compounds containg them in a suitable solvent or solvent system and forming microspheres from the resulting solution. The microspheres are administered to an individual as protection from conditions where delivery of nucleic acids is useful, such as in treatment of autoimmune disease.
