Abstract: Provided herein are methods of producing engineered T cell compositions enriched for CD57 negative and/or CD27 positive T cells, such as from a plurality of donors. In some embodiments, the T cells are engineered with a recombinant receptor, such as a chimeric antigen receptor (CAR). Also provided herein are engineered T cell compositions containing T cells enriched for CD57 negative and/or CD27 positive T cells derived from a plurality of different donors, including compositions in which the T cells are engineered with or express a recombinant receptor (e.g. CAR). Also provided are methods of using the engineered T cell compositions in adoptive therapy, including in connection for cancer immunotherapy, such as for allogeneic therapies or for administration to one or more subjects in which the T cells are not derived from the subject(s) to whom the compositions are administered.

Abstract: The present disclosure provides cell populations enriched for CD57 negative T cells, or depleted for CD57 positive cells, and methods for stimulating, cultivating, expanding, and/or genetically engineering cell populations enriched for CD57? T cells or depleted for CD57+ T cells. Also included are methods for generating, isolating, enriching, or selecting CD57? T cells or depleting CD57+ cells, such as by negative selection.

Abstract: The present invention provides compositions, kits, assemblies, libraries, arrays, and high throughput methods for large scale structural and functional characterization of gene expression regulatory elements in a genome of an organism, especially in a human genome. In one aspect of the invention, an array of expression constructs is provided, each of the expression constructs comprising: a nucleic acid segment operably linked with a reporter sequence in an expression vector such that expression of the reporter sequence is under the transcriptional control of the nucleic acid segment, the nucleic acid segment varying in the library and having a diversity of at least 50. The nucleic acid segments can be a large library of gene expression regulatory elements such as transcriptional promoters. The present invention can have a wide variety of applications such as in personalized medicine, pharmacogenomics, and correlation of polymorphisms with phenotypic traits.
