20220229043 · 2022-07-21 ·

Provided herein are methods for obtaining tumor-targeting T cells, as well as for identifying tumor-targeting TCRs.

HIGH-EFFICIENCY METHOD FOR PRODUCING GENETICALLY MODIFIED CELLS

An object of the present invention is to improve the efficiency of a method for producing chimeric antigen receptor (CAR)-expressing cells. The present invention provides a method for producing genetically modified mammalian cells, comprising the steps of: a) introducing a polynucleotide encoding a chimeric antigen receptor (CAR) protein to a cell population comprising T cells derived from a mammal by a transposon method to obtain a genetically modified cell population; b) providing an endogenous cell population derived from the mammal expressing a protein that binds to the CAR; and c) coculturing the genetically modified cell population of the step a) and the endogenous cell population of the step b).

Ex vivo generation of γδ Foxp3.SUP.+ .regulatory T cells and therapeutic uses thereof

The present invention relates to a method for ex vivo generating and expanding γδ Foxp3.sup.+ regulatory T cells, and therapeutic uses thereof. The inventors performed the induction of Foxp3+ expression in ex vivo human induced tumor-antigen specific CD4+ TCRγδ unrestricted T cells and the induction of autologous CD8-mediated T-cell responses against tumor-antigen specific FOXP3 expressing CD4+ TCRγδ unrestricted T cells. The inventors developed a method to ex vivo generated and expanded antigen specific Foxp3 expressing CD3+ TCRγδ+ unrestricted T cells, committed to exclusively exert regulatory activity, whichever culture condition of stimulation is. In particular, the present invention relates to a method for generating ex vivo γδ Foxp3+ regulatory T cells having the following phenotype: CD3+ TCRγδ+ Foxp3+.

GENERATING HPV ANTIGEN-SPECIFIC T CELLS FROM A NAÏVE T CELL POPULATION

Safe, rapid, and efficient methods for producing antigen-specific T cells recognizing human papilloma virus (HPV antigens); HPV-specific T cells, and methods for treating HPV infections and HPV-related malignancies by adoptive transfer of HPV-specific T cells.

MODIFIED HEMATOPOIETIC STEM/PROGENITOR AND NON-T EFFECTOR CELLS, AND USES THEREOF

Hematopoeitic stem/progenitor cells (HSPC) and/or non-T effector cells are modified to express an extracellular component including a tag cassette. The tag cassette can be used to activate, promote proliferation of, detect, enrich, isolate, track, deplete and/or eliminate modified cells. The cells can also be modified to express a binding domain.

COMPOSITIONS AND METHODS FOR DIFFERENTIATING STEM CELLS INTO NK CELLS

The disclosure features methods and compositions for differentiating stem cells into hematopoietic stem and progenitor cells (HSPC) and/or Natural Killer (NK) cells. The methods and compositions described herein are used to differentiate stem or progenitor cells having at least one gene-edit that is maintained in the differentiated cell. Also provided are differentiated cells produced using the methods and compositions described herein for therapeutic applications.

IMMUNOTHERAPEUTIC COMPOSITIONS AND USE THEREOF
20220195071 · 2022-06-23 ·

Combination therapies for the treatment of cancer comprising an immunostimulatory fusion molecules that include an immune cell targeting moiety and a cytokine molecule; and an immune cell loaded with protein nanogels that include a reversibly crosslinked cytokine molecule and a polymer, pharmaceutical and formulations thereof, and methods of using and making the same, are disclosed.

Ex vivo generation of MHCII restricted CD4.SUP.+ .FOXP3.SUP.+ .regulatory T cells and therapeutic uses thereof

The present invention relates to a method for ex vivo generating and expanding MHCII restricted CD4.sup.+ Foxp3.sup.+ regulatory T cells, and therapeutic uses thereof. The inventors here demonstrated the optimal conditions for inducing Foxp3 expression in naive CD3+ CD4+ TCRαβ+ MHCII restricted T following polyclonal or following antigen-specific activation. They also developed an experimental procedure to generate autologous CD8+ T cell lines functionally committed to lyse tumor-antigen specific FOXP3 expressing TCRαβ+ MHCII restricted T cells, pathogenic CD4+ T cells that favour tumor cell immune evasion. In particular, the present invention relates to a method for generating ex vivo MHCII restricted CD4+ Foxp3+ regulatory T cells having the following phenotype: CD3+ CD4+ Foxp3+.

Genetically Engineered Cells and Uses Thereof

Provided are genetically engineered induced pluripotent stem cells (iPSCs) and derivative cells thereof expressing a chimeric antigen receptor (CAR) and methods of using the same. Also provided are compositions, polypeptides, vectors, and methods of manufacturing.
