Abstract: This disclosure provides nano-scale Artificial Antigen Presenting Cells (aAPC), which deliver stimulatory signals to lymphocytes, including T-helper lymphocytes, for use as a powerful tool for immunotherapy.

Abstract: The present invention provides an isolated cell composition suitable for adoptive immunotherapy, as well as methods of manufacturing the cell compositions and methods of treatment with the cell compositions. The composition comprises, in a pharmaceutically acceptable carrier, at least about 106 CD8+ T cells specific for target peptide antigen(s). In various embodiments, the composition is predominately CD8+ T cells, and at least about 20% of T cells in the composition exhibit a central or effector memory phenotype, providing for a robust and durable adoptive therapy from a natural T cell repertoire that has undergone natural selection.

Abstract: The invention in various aspects provides for magnetic enrichment and/or expansion of antigen-specific T cells, allowing for identification and characterization of antigen-specific T cells and their T cell receptors (TCRs) for therapeutic and/or diagnostic purposes, as well as providing for production of antigen-specific engineered T cells for therapy. Incubation of paramagnetic nano-aAPCs in the presence of a magnetic field, either during enrichment and/or expansion steps, activates T cells through magnetic clustering of paramagnetic particles on the T cell surface.

Abstract: Antigen-specific T cells, including nave T cells, and including rare precursor cells are enriched and expanded in culture. Enrichment and expansion provides a platform for more effective immunotherapy by adoptive transfer, as well as platforms for personalizing immunotherapy by determining T cell reactivity with a library of candidate peptide antigens.

Abstract: The present invention provides an isolated cell composition, which in some embodiments is suitable for adoptive immunotherapy, as well as methods of manufacturing the cell compositions and methods of treatment with the cell compositions. The composition comprises, in a pharmaceutically acceptable carrier, at least about 106 CD8+ T cells specific for target peptide antigen(s), which comprises T memory stem (TSCM) cells. In various embodiments, the composition is from about 1% to about 100% T memory stem cells, providing for a robust and durable adoptive therapy, as well as providing for T cell engineering advances.

Abstract: Platforms comprising at least one lymphocyte affecting molecule and at least one molecular complex that, when bound to an antigen, engages a unique clonotypic lymphocyte receptor can be used to induce and expand therapeutically useful numbers of specific lymphocyte populations. Antigen presenting platforms comprising a T cell affecting molecule and an antigen presenting complex can induce and expand antigen-specific T cells in the presence of relevant peptides, providing reproducible and economical methods for generating therapeutic numbers of such cells. Antibody inducing platforms comprising a B cell affecting molecule and a molecular complex that engages MHC-antigen complexes on a B cell surface can be used to induce and expand B cells that produce antibodies with particular specificities.
