Abstract: The present invention is directed to an in vitro method of producing a recombinant AAV virion in a mammalian host cell that comprises a functional adenoviral E1A gene (e.g., a HEK 293T cell) and rAAV virions made by the method.

Abstract: Provided herein are recombinant circular RNAs comprising at least one protein-coding nucleic acid sequence, wherein the protein-coding nucleic acid sequence encodes a reprogramming factor (e.g., a transcription factor), wherein the reprogramming factor is Oct3/4, Klf4, Sox2, Nanog, Lin28, c-Myc, or L-Myc, or a fragment or variant thereof. Also provided herein are methods of producing induced pluripotent stem cells (iPSC), the method comprising contacting a somatic cell with at least one of the recombinant circular RNAs described herein and maintaining the cell under conditions under which a reprogrammed iPSC is obtained.

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: Disclosed are an in vitro method of producing a recombinant AAV virion in a mammalian host cell that comprises a functional adenoviral E1A gene (e.g., a HEK 293 cell) and rAAV virions made by the method.

Abstract: The present invention is directed to an in vitro method of producing a recombinant AAV virion in a mammalian host cell that comprises a functional adenoviral E1A gene and rAAV virions made by the method. Host cells are transfected with varying ratios of plasmids comprising the E1A gene and virions.
