Engineered Treg-like cells, CD4.sup.LVFOXP3 T cells, and their use in cellular therapy to promote immune tolerance are disclosed. In particular, CD4.sup.LVFOXP3 T cells are produced by transduction of CD4.sup.+ T cells with a lentiviral vector expressing FOXP3 under the control of a constitutive promoter. Transduced cells express FOXP3 at high and persistent levels and acquire immune suppressive characteristics resembling naturally occurring Treg cells.

Disclosed herein include a natural killer (NK) cell genetically modified to comprise a recombinant nucleic acid encoding C-X-C Motif Chemokine Receptor 1 (CXCR1), a pharmaceutical composition comprising the NK cell, methods of preparing the NK cell, and method of treating cancer or tumor using the NK cell.

Compositions comprising and methods for the treatment of cancer using a neoTCR based cell therapy with a CD8 expression construct.

Compositions comprising and methods for the treatment of cancer using a neoTCR based cell therapy with a CD8 expression construct.

Among the various aspects of the present disclosure is the provision of methods and compositions for the generation of cells of endodermal lineage and beta cells and uses thereof.

A recombinant natural killer (NK) cell or T-cell composition is transfected with a nucleic acid encoding i) a homing receptor; ii) an antigen binding protein (ABP) or a chimeric antigen receptor (CAR) that specifically binds a target antigen; iii) an Fc Receptor; and/or iv) a secreted immune modulator selected from a TGFβ inhibitor and/or IL-12, where the recombinant cell is gamma (γ)-irradiated conferring inhibition of cell proliferation with transient activity of the transfected molecules including the secreted immune modulators for up to 72 hours.

A method of treating a Philadelphia chromosome-positive tumor in a subject comprises administering to the subject a therapeutic composition comprising an incubated combined mixture of (a) a first component comprising (i) Philadelphia chromosome-positive tumor lysate, (ii) plasmid encoding bcr/abl fusion protein, or (iii) bcr/abl fusion peptide; and (b) a second component comprising plasmacytoid dendritic cells expressing Toll-like receptor 9 and modified for stable expression of CD40 ligand or GM-CSF by a nucleotide sequence engineered into said plasmacytoid dendritic cells.

Compositions comprising and methods for the treatment of cancer using a neoTCR based cell therapy with a knockout of the expression of the TET2 gene.

Compositions comprising and methods for the treatment of cancer using a neoTCR based cell therapy with a CD8 expression construct.

A method of manipulating allogeneic cells for use in allogeneic cell therapy providing a composition of highly activated allogeneic T-cells which are infused into immunocompetent cancer patients to elicit a novel anti-tumor immune mechanism, or Mirror Effect. In contrast to current allogeneic cell therapy protocols where T-cells in the graft mediate the beneficial graft vs. tumor (GVT) and detrimental graft vs. host (GVH) effects, the allogeneic cells of the present invention stimulate host T-cells to mediate the mirror of these effects. The mirror of the GVT effect is the host vs. tumor (HVT) effect. The mirror of the GVH effect is the host vs. graft (HVG) effect The anti-tumor HVT effect occurs in conjunction with a non-toxic HVG rejection effect. The highly activated allogeneic cells of the invention can be used to stimulate host immunity in a complete HLA mis-matched setting in a patient.
