Aspects of the disclosure include compositions and methods for treatment of a wide variety of diseases/conditions with engineered host cells, where the engineered host cells comprise a chimeric adaptor (CAD) polypeptide comprising DAP10 and at least one chimeric receptor. The CAD polypeptide may comprise substitution mutations and/or additional protein domains that function in conjunction with associated receptors to enhance cell survival and proliferation of the host cells, and to enhance cell killing activities of non-host cells.

Provided herein are genetically engineered T cells containing a chimeric antigen receptor (CARs), and related methods and uses thereof in allogeneic cell therapy. In some embodiments, the T cells are genetically engineered with a CAR and are further genetically engineered by one or more strategies to reduce host immune recognition of the engineered T cells, such as by heterologous expression of one or more additional transgenes and by genetic disruption to reduce or eliminate expression or one or more endogenous protein. Also provided are cell compositions containing the engineered T cells, and related methods, kits and systems for producing the engineered T cells. Also provided are methods of making and using the engineered T cells for cell therapy, including in connection with cancer immunotherapy comprising adoptive transfer of the engineered T cells.

Systems and methods are presented that provide for improved NK cell function. In preferred aspects, NK-92 cells express recombinant er/LSP-IL-15 to so render the NK-92 cells independent of exogenous cytokines and to provide extracellular immune stimulation.

The present disclosure provides, inter alia, compositions, cell populations and pharmaceutical compositions and methods useful for the treatment of inflammatory diseases or disorders. In some embodiments, the compositions, cell populations and pharmaceutical compositions and methods comprise a population of CD44.sup.+ cells modified ex vivo via treatment with a CD44 ligand for a period of time sufficient to prime the cells to produce elevated levels of one or more anti-inflammatory or immunomodulatory molecules relative to a native populations of CD44.sup.+ cells. In some embodiments, the compositions, cell populations and pharmaceutical compositions and methods comprise a population of CD44.sup.+ cells modified ex vivo via a treatment that is effective to target cells to sites of inflammation.
