The disclosure provides methods of treating a condition, disease, or disorder in a subject that involves metabolically reprogrammed cells whose activation, function, growth, proliferation, or survival depends on increased activity of at least one metabolic pathway selected from the group consisting of glutamine metabolism, glycolysis, and fatty acid synthesis, comprising administering to the subject a compound having formula (I):

##STR00001##

and the pharmaceutically acceptable salts thereof, wherein R.sub.1, R.sub.2, R.sub.2, and X are as defined as set forth in the specification. Compounds having formula (I) are prodrugs that release glutamine analogs, e.g., 6-diazo-5-oxo-L-norleucine (DON).

The disclosure provides methods of treating cancer in a subject or preventing a relapse or reducing the incidence of relapse of cancer in a subject in remission, comprising administering to the subject: (a) a therapeutically effective amount of an immunotherapeutic agent, e.g., an immune checkpoint blockade therapy, an adoptive cellular therapy, a marrow-infiltrating lymphocytes, an adenosine A2aR inhibitor, or an antibody; and (b) a compound having formula (I):

##STR00001##

and the pharmaceutically acceptable salts thereof, wherein R.sub.1, R.sub.2, R.sub.2, and X are as defined as set forth in the specification. Compounds having formula (I) are prodrugs that release glutamine analogs, e.g., 6-diazo-5-oxo-L-norleucine (DON).

Provided herein are compositions and methods for treating cancer. The compositions include a modified T cell comprising a nucleic acid encoding a calcium translocating channelrhodopsin (CatCh) polypeptide. The methods comprise administering to the subject with cancer one or more modified T cells comprising a nucleic acid encoding a calcium translocating channelrhodopsin (CatCh) polypeptide and exposing the one or more modified T cells in the subject to a visible light source.

The present invention provides for modified natural killer (NK) cells that are resistant to TGF-? stimulation due to suppressed Smad3 activity in these cells. Also provided are compositions comprising these modified NK cells, as well as methods of treating cancer by using the cells.

The present disclosure relates to compositions and methods for compositions, methods, and kits for treating cancer using chimeric antigen receptor (CAR) modified cells. Some embodiments of the present disclosure relate to an isolated nucleic acid sequence encoding CAR. The CAR may include an antigen binding domain, a transmembrane domain, a costimulatory signaling region, and a CD3 zeta signaling domain. The antigen binding domain may bind to an antigen of a non-essential organ.

Methods and compositions are provided for combined transplantation of a solid organ and hematopoietic cells to a recipient, where tolerance to the graft is established through development of a persistent mixed chimerism. An individual with persistent mixed chimerism, usually for a period of at least six months, is able to withdraw from the use of immunosuppressive drugs after a period of time sufficient to establish tolerance.

Dendritic cells containing tumor lysate loaded particles are prepared. The dendritic cells present tumor antigens to elicit the Major Histocompatibility Complex class I pathway and can be used as a vaccine to treat cancer, including ocular melanoma.

The novel synergistic combination of immune checkpoint blockade and hematopoietic stem cell transplantation and/or hematopoietic stem cell mobilization yield synergistic effects in disease therapy.

Disclosed herein are methods and compositions for modifying TCR genes, using nucleases (zinc finger nucleases or TAL nucleases) to modify TCR genes.
