Provided are methods, compositions, and cells for use in adoptive cell therapy for the treatment of cancer. The methods involve administering an effective amount of cells to a subject, wherein the cells are modified ex vivo to suppress endogenous Zbtb20 expression and/or activity within the modified cells. The cells may comprise a dominant negative Zbtb20 capable of suppressing endogenous Zbtb20 activity, at least one shRNA capable of suppressing endogenous Zbtb20 expression, or at least one sgRNA capable of suppressing endogenous Zbtb20 expression. The cells may further comprise an exogenous TCR and/or CAR suitable for treating cancer. The method can further involve administering one or more additional cancer therapies, such as cells which express at least one exogenous TCR and/or CAR suitable for treating cancer. The method can provide various advantages, such as a reduction and/or elimination of an amount of cancer cells in the subject.

Compositions and methods are provided for production of cells useful in regenerative therapies.

The invention provides novel compounds, compositions and formulations of liposomes, microbubbles and/or nanodroplets, and emulsions thereof, that are useful in delivery of various nucleic acids and genes (e.g., single stranded RNA, DNA, si-RNA and CRISPR constructs), as well as methods of preparation and use thereof including methods of imaging and gene delivery using ultrasound activation.

Embodiments of the disclosure encompass improvements on cell therapies by allowing the cells to be more effective for cancer treatment, including in a solid tumor microenvironment. In specific cases, the cells are modified to have reduced or inhibited levels of expression of T-Cell Death Associated Gene 8 (TDAG8), such as by CRISPR gene editing. In specific cases, the cells are further modified to express, for example, one or more engineered receptors, one or more cytokines, and optionally a suicide gene.

Methods for treating a cell, tissue, or organ and for treating an age-related disease or condition are provided, where the cell, tissue or organ is contacted with a synthetic, persistent RNA vector comprising one or more heterologous polynucleotide sequences, each of the one or more heterologous polynucleotide sequences encoding for a reprogramming factor. Contacting achieves expression of the one or more reprogramming factors in the cell, tissue, or organ to treat the age-related disease or condition. In an embodiment, the method is used to obtain a rejuvenated cell, tissue, or organ with retention of cellular identity.
