Abstract: The disclosure provides methods of treating a tissue, organ, organoid or organ culture, the method comprising treating a tissue, organ, organoid or organ culture in vitro with a composition comprising one or more cell turnover factors produced by cells exposed to a stress condition. The disclosure also provides methods of increasing regeneration of a tissue in an organ of a subject, the method comprising administering to the subject a composition comprising one or more cell turnover factors produced by cells exposed to a stress condition, wherein the composition is administered to the subject in an amount sufficient to increase regeneration of the tissue relative to a subject that is not treated with the composition.

Abstract: The invention provides methods of treating a cancer in a subject, comprising administering to the subject a combination of (a) an anti-neoplastic agent and (b) an agent that induces iron-dependent cellular disassembly, thereby treating the cancer in the subject. In some embodiments, the cancer is resistant to the anti-neoplastic agent.

Abstract: In one aspect, the invention provides methods of increasing immune response by administering postcellular signaling factors produced by cells exposed to a stress condition. In one aspect, the invention provides methods of increasing immune response by administering in combination (a) a Stimulator of Interferon Genes (STING) agonist and (b) a purinergic receptor agonist. The increase in immune response may be used, for example, for treatment of infection or cancer. The invention also provides screening assays for identification of compounds that induce production of postcellular signaling factors which are also immunostimulatory agents. The invention further provides methods for identifying postcellular signaling factors with immunostimulatory activity. In another aspect, the invention provides methods of decreasing immune response by administering to a cell, tissue or subject a purinergic receptor antagonist alone or in combination with a Stimulator of Interferon Genes (STING) antagonist.

Abstract: The invention provides methods of decreasing immune response by inhibiting iron-dependent cellular disassembly. The decrease in immune response may be used, for example, for treatment of a disorder associated with iron-dependent cellular disassembly, including an autoimmune disorder, allergy, or an inflammatory disorder. The invention also provides screening assays for identification of compounds that inhibit iron-dependent cellular disassembly and are also immunoinhibitory agents.
