Abstract: An implantable or injectable scaffold comprising immunostimulatory compounds and a suppressor of regulatory T cell induction is provided for use in immunotherapy treatments, including the treatment of cancers and other tumors, in particular solid tumors including inoperable tumors, as well as for other applications of immune enhancement and/or suppression.

Abstract: A microparticle is described comprising an antigen and a costimulatory component derived from an antigen presenting cell. The microparticle may be used for stimulating T cells ex vivo, followed by administration to a subject, e.g., as part of a personalized, customized therapeutic treatment of cancer or a tumor, an autoimmune disease or an allergic reaction, hypersensitivity reaction, an infection or infectious disease, an injury or other damage, a transplant or other surgical site, or a blood clot. It may also be used for the controlled release of a cytokine for the regulation of immunity in general and for other therapeutic uses. Methods of treating a disease or medical condition in a subject by exposing leukocytes from the subject to the microparticle, then reinfusing the leukocytes into the subject are provided. Methods of preparing an activated cytotoxic T cell population specific for an antigen are also provided.

Abstract: Synthetic liposomal nanoparticles comprising a cell-free transcription and translation machinery, a plasmid encoding a cytokine, and a regulatable caged ATP molecule, as well as microparticles encasing the synthetic liposomal nanoparticles and methods of making and using the synthetic liposomal nanoparticles, are described herein. These liposomal nanoparticles may be used for the controlled release o a cytokine within a localized environment of, for example a tumor, as part of a therapeutic treatment of cancer, or for localized treatment at a focus of interest of an autoimmune disease, an allergic reaction or hypersensitivity reaction, a localized site of an infection or infectious disease, a localized site of an injury or other damage, a transplant or other surgical site, or a blood clot. Further, microparticles produced by encapsulating hundreds of liposomal nanoparticles, and their therapeutic uses, are also described.
