Abstract: Some embodiments of the disclosure provides a chimeric antigen receptor (CAR) comprising an antigen binding domain specific for FLT3, an antigen binding domain specific for a second antigen, a transmembrane domain, and an intracellular T cell signaling domain. Some embodiments of the disclosure provides bicistronic CARs. Nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of a proliferative disorder, e.g., cancer, in a mammal and methods of treating or preventing a proliferative disorder, e.g., cancer, in a mammal are also disclosed.

Abstract: The invention provides improved adoptive immunotherapy compositions and methods of making the same.

Abstract: The present invention relates to the fields of life sciences and medicine. Specifically, the invention relates to cancer therapies. More specifically, the present invention relates to oncolytic adenoviral vectors and cells and pharmaceutical compositions comprising said vectors. The present invention also relates to said vectors for treating cancer in a subject and a method of treating cancer in a subject. Furthermore, the present invention relates to methods of producing CD40L in a cell and increasing tumor specific immune response and apoptosis in a subject, as well to uses of the oncolytic adenoviral vector of the invention for producing CD40L in a cell and increasing tumor specific immune response and apoptosis, while decreasing tumor-associated immunosuppression, in a subject.
