The present disclosure provides nucleic acid molecules encoding an engineered antigen receptor, such as a chimeric antigen receptor or exogenous T cell receptor, and an inhibitory nucleic acid molecule, such as an RNA interference molecule. The present disclosure further relates to nucleic acids, DNA constructs, vectors, pharmaceutical compositions, genetically-modified cells, and methods of treatment that utilize the nucleic acid molecules of the invention.

Provided herein are methods for selecting a population of cells expressing a target polypeptide. In some aspects, the disclosure provides methods for sorting and selecting populations of transfected host cells based on their early expression of a selectable polypeptide. In certain embodiments, the sorting is performed using fluorescence-activated cell sorting or magnetic-activated cell sorting based on the selectable polypeptide. Such selection methods can be further utilized to generate clonal populations of producer cells, e.g. for large-scale manufacturing of a target polypeptide of interest.

The present disclosure relates to a soluble CD52 glycoprotein and its use in treating diseases regulated by effector T-cells, for example autoimmune diseases such as type 1 diabetes. The present disclosure also relates to fusion proteins comprising the soluble glycoprotein, to cells expressing high levels of CD52, and to diagnostic methods based on the detection of CD52 expression levels in a subject.
