This disclosure relates to particles, compositions, methods of making, and methods of use thereof.

Contemplated compositions and methods generate a durable immune synapse and so lead to activated T-cells and memory T-cell formation by use of selected co-stimulatory receptors and their ligands in conjunction with selected neoepitopes. Moreover, immune competent cells are attracted into a tumor microenvironment after activation of the T-cells using hybrid or chimeric binding proteins that comprise a chemokine portion and that target components of necrotic cells.

The invention covers the use of certain classes of lipids including cationic lipids in ex-vivo dendritic cell therapies. The cationic lipids enhance antigen uptake, processing and presentation of the processed antigens by dendritic cells to CD8+and CD4+T-cells via the MHC classes I and II presentation pathways respectively. Antigen uptake via cationic lipid by dendritic cells result in significant lowering of the population of the immune suppressive regulatory T cells in the tumors and a significant increase of the tumor targeting cytotoxic T-cells. Loss of regulatory T cells and increase of tumor specific cytotoxic cells are conducive to effective elimination of the tumors.

The present invention relates to a method for preparing a dendritic cell, a dendritic cell prepared thereby and a use thereof, and more specifically, to a method for preparing a dendritic cell, including: treating a dendritic cell at a maturation stage rather than at an immature stage with an antigen bound to a peptide having a cell membrane permeability to prepare a dendritic cell with improved antigen-presenting ability, a dendritic cell prepared by the method, and an immunotherapeutic agent thereof, a use for anti-tumor vaccines, or a pharmaceutical composition for treating tumors, containing the same.

The invention relates to cell preparations comprising dendritic cell (DC) sub-populations, methods of obtaining such cell preparations, and the use of such preparations for improved immune and cancer therapy. More specifically, embodiments of the invention relate to the production and use of substantially pure human DC subpopulations, useful in the preparation of vaccines against inflammatory diseases and cancer, as well as cell preparations for eliciting immuno-tolerance.

The present invention provides compositions and methods for treating cancer.

The invention provides methods of preventing or treating ocular diseases and conditions by adoptive transfer of plasmacytoid dendritic cells and related compositions.

The invention relates to a dendritic cell (DC) vaccine for use in a method of treating cancer in a patient, wherein the patient is selected for treatment with said DC vaccine. The selection inter alia comprises determining in a tumor sample from the patient the amount of CD8+ T-cells and/or the tumor mutation burden (TMB) and comparing the determined amount to a predetermined threshold level. The selection allows identifying patients that particularly benefit from DC treatment.

The present disclosure relates to the preparation of citrullinated vimentin antigen-specific immune tolerogenic dendritic cells and a composition for preventing or treating heart failure after myocardial infarction comprising the same. According to the present disclosure, it is confirmed that immune tolerogenic dendritic cells differentiated by treating immature dendritic cells with citrullinated vimentin regulate the expression of immune-related factors and have an excellent therapeutic effect on heart failure caused by myocardial infarction.

The invention relates to compounds based on a recombinant form of the CCP6 region of C4BP and an oligomerization domain for use in the prevention and/or treatment of immunological diseases. Moreover, the invention relates to methods for obtaining tolerogenic dendritic cells and tolerogenic macrophages using the compounds of the invention and to the cells obtained by these methods and their therapeutic uses.
