Innate lymphoid cells (ILCs) represent innate versions of T helper and cytotoxic T cells that differentiate from committed ILC precursors (ILCP). Still, how ILCP relate to mature tissue-resident ILCs remains unclear. ILCP that are present in the blood and all tested lymphoid and non-lymphoid human tissues were identified. Human ILCP fail to express the signature transcription factors (TF) and cytokine outputs of mature NK cells and ILCs but are epigenetically poised to do so. Human ILCP robustly generate all ILC subsets in vitro and in vivo. While human ILCP express RAR related orphan receptor C (RORC), circulating ILCP can be found in RORC-deficient patients that retain potential for EOMES.sup.+ NK cells, T-BET.sup.+ ILC1, GATA-3.sup.+ ILC2 and for IL-22.sup.+ but not for IL-17A.sup.+ ILC3. A model of tissue ILC differentiation (‘ILC-poiesis’) is proposed whereby diverse ILC subsets are generated in situ from ILCP in response to environmental stressors, inflammation and infection.

Media and methods for differentiating NK progenitor cells into NK cells are disclosed. The NK differentiation media comprises a pyrimidoindole compound such as UM171 or UM729.

Several embodiments disclosed herein relate to methods and processes for the co-expansion of multiple types of immune cells, in order to generate a mixed cell population. Some embodiments relate to the use of various stimuli specific to the various subpopulations to achieve expansion of those subpopulations at a particular time in a culturing process in order to generate an expanded population of immune cells having a desired ratio of the various subpopulations. In several embodiments, such mixed cell populations exhibit desirable characteristics, such as cytotoxic effects against tumor cells that enhance the efficacy of cancer immunotherapy.

The present disclosure relates to the field of cell therapy, and more specifically, to improving CAR and/or TCR function through improvement of the tumor microenvironment via improvement in cytokine signaling.

The present invention relates to a serum-free conditioned medium that solves the drawbacks mentioned in the prior art, as it does not require prior handling of the cells, and it furthermore allows starting from a large population with no additional cost. This medium favors in vitro proliferation and conservation of the pluripotency potential that allows maintaining a state that is undifferentiated with respect to the subpopulation of cancer stem cells (CSCs) and in turn does not allow survival of the differentiated cells.

Provided herein are active CXCR4.sup.+ CD8.sup.+ T cells, active CXCR4.sup.+ type-1 CD4.sup.+ T cells and active CXCR4.sup.+ NK cells and populations of those cells, methods for making active CXCR4.sup.+ T cells and NK cells and populations of those cells, and methods for using active CXCR4.sup.+ T cells and NK cells and populations of those cells for the treatment of cancer, precancerous conditions and chronic infections.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

Compounds that either produced a higher proportion or greater absolute number of phenotypically identified nave, stem cell memory, central memory T cells, adaptive NK cells, and type I NKT cells are identified. Compositions and methods for modulating immune cells including T, NK, and NKT cells for adoptive cell therapies with improved efficacy are provided.

Provided are compounds that target the lanthionine synthetase C-like protein 2 pathway and cells, such as immune cells, prepared in vitro with the compounds. The compounds and cells can be used to treat a number of conditions, including infectious diseases, hyperproliferative disorders, inborn errors of metabolism, chronic immunometabolic diseases, autoimmune diseases, organ transplant rejection, inflammatory disorders, and chronic pain, among others.
