Abstract: 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.

Abstract: The present invention is related to a method for preparing small spherical particles of an active agent by providing a solution in a single liquid phase. The single liquid phase comprises an active agent, a phase separation enhancing agent, and a first solvent. A phase change is induced at a controlled rate in the solution to cause a liquid-solid phase separation of the active agent and to form a solid phase and a liquid phase. The solid phase comprises solid small spherical particles of the active agent. The liquid phase comprises the phase separation enhancing agent and the solvent. The small spherical particles are substantially spherical and having a size from about 0.01 ?m to about 200 ?m.

Abstract: 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.

Abstract: Microparticles formed by mixing a macromolecule with a polymer at a pH near the isoelectric point of the macromolecule and incubating the mixture in the presence of an energy source for a predetermined length of time. The microparticles are composed of homogeneously distributed, intertwined macromolecule and polymer. Each microparticle allows aqueous fluids to enter and allows solubilized macromolecule and polymer to exit the microparticle and may be formulated to provide a sustained release of macromolecule and polymer from the interior of the microparticle when placed in an appropriate aqueous medium, such as under physiological conditions. Methods of production and methods of use for research, diagnostics and therapeutics are provided.
