The invention provides improved vector composition comprising chimeric antigen receptor for adoptive T cell therapies.

Various embodiments of the present disclosure provide therapeutic compositions and associated methods for improved hematopoietic stem cell transplantations, including methods to enhance protection from graft versus host disease while maintaining effective immune responses such as graft versus tumor immune responses.

Disclosed are compositions and methods for targeted treatment of infections and cancers expressing cancers. In particular, tumor infiltrating lymphocytes (TILs) are genetically engineered to express chimeric antigen receptor (CAR) polypeptides to produce CAR-TILs that can be used with adoptive cell transfer to target, penetrate, and kill solid tumor masses. Therefore, also disclosed are methods of providing an immunotherapy in a subject with an infection or cancer that involves adoptive transfer of the disclosed CAR-TILs.

The invention provides compositions and methods for treating a refractory, relapsed or resistant cancer or a chronic infectious disease. In particular the present invention relates to a modified immune cell with reduced SUV39H1 activity, for use in the treatment of a patient suffering from a refractory, relapsed or resistant cancer or suffering from a chronic infectious disease, wherein the cell expresses one or more engineered antigen-specific receptors that bind an antigen associated with the cancer or the chronic infectious disease

Chimeric antigen receptors containing ROR1 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.

The present invention relates to an anti-L1CAM antibody specifically binding to L1CAM antigen or an antigen-binding fragment thereof, a chimeric antigen receptor comprising same, and uses thereof. The anti-L1CAM antibody or the antigen-binding fragment of the present invention is excellent in specificity and affinity to L1CAM and thus may be used in the treatment and diagnosis of cancers related to high expression of L1CAM and diseases related to inflammatory disorders. In particular, when the chimeric antigen receptor comprising the anti-L1CAM antibody of the present invention is expressed in effector cells such as T lymphocytes, the chimeric antigen receptor may be effectively used as immunotherapy for cancers related to L1CAM and inflammatory disorders.

The present disclosure provides epitopes of CD45, and binding agents such as antibodies, antibody fragments, peptides, and small molecules capable of binding to those epitopes. The present disclosure also provides methods of treating cancers, hematological diseases and disorders, and immune diseases and disorders, using these binding agents.
