In various certain embodiments, a method of treating a cancer in a subject in need thereof, comprising administering to the subject a therapeutically effect amount of a T cell composition contemplated herein is provided. In particular embodiments, the MM is selected from the group consisting of: overt multiple myeloma, smoldering multiple myeloma, plasma cell leukemia, non-secretory myeloma, IgD myeloma, osteosclerotic myeloma, solitary plasmacytoma of bone, and extramedullary plasmacytoma. In certain embodiments, the hematological malignancy is a B-cell malignancy selected from the group consisting of: multiple myeloma (MM), chronic lymphocytic leukemia (CLL), or non-Hodgkin's lymphoma (NHL). In certain embodiments, the NHL is selected from the group consisting of: Burkitt lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), diffuse large B-cell lymphoma, follicular lymphoma, immunoblastic large cell lymphoma, precursor B-lymphoblastic lymphoma, and mantle cell lymphoma. In various embodiments, a composition comprising a population of immune effector cells contemplated herein and a physiologically acceptable excipient is provided. Moreover, expanded cells are able to subsequently differentiate and provide immune effector cell functions. The main characteristic of CARs are their ability to redirect immune effector cell specificity, thereby triggering proliferation, cytokine production, phagocytosis or production of molecules that can mediate cell death of the target antigen expressing cell in a major histocompatibility (MHC) independent manner, exploiting the cell specific targeting abilities of monoclonal antibodies, soluble ligands or cell specific coreceptors.

Without wishing to be bound to any particular theory, the inventive methods contemplated herein uncouple T cell proliferation from differentiation to produce T cells having superior properties, e.g., increased survival, expansion, and persistence in vivo along with a concomitant decrease in differentiation, compared to existing T cell compositions in the art.



In one embodiment, "substantially the same" refers to a quantity, level, value, number, frequency, percentage, watch live sexcam dimension, size, amount, weight or length that produces an effect, e.g., a physiological effect, that is approximately the same as a reference quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length. As used herein, the term "substantially" refers to a quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length that is 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or higher of a reference quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length. As used herein, the term "about" or "approximately" refers to a quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length that varies by as much as 30, 25, 20, 25, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1% to a reference quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length.



Reference throughout this specification to "one embodiment," "an embodiment," "a particular embodiment," "a related embodiment," "a certain embodiment," "an additional embodiment," or "a further embodiment" or combinations thereof means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. All publications, patents and patent applications cited herein are hereby incorporated by reference in their entirety. Without wishing to be bound to any particular theory, the present inventor has surprisingly and https://Watchlivesexcam.com/ unexpectedly discovered that modulation of cell signaling pathways in T cells, which pathways are normally associated with proliferation in cancer cells, results in substantially maintaining or insubstantially reducing T cell proliferation and decreasing T cell differentiation during T cell expansion compared to T cells where the cell signaling pathways are not modulated. Accordingly, the methods and compositions contemplated herein represent a quantum improvement compared to existing adoptive cell immunotherapies.
