Engineered immune cell and use thereof

An engineered immune cell, which expresses (i) a cell surface molecule that specifically recognizes a ligand, (ii) an exogenous interleukin, and (iii) an exogenous Flt3L, XCL2, and/or XCL1; the engineered immune cell can be used for treating cancer, infection, or autoimmune diseases; and compared with a traditional engineered immune cell, the engineered immune cell has significantly improved tumor killing activity.

Compositions and methods for immunotherapy of NPM1c-positive cancer

The present disclosure relates to compounds (e.g., antibodies, antigen-binding fragments thereof, bispecific molecules, or chimeric antigen receptor polypeptides) that bind to a neoepitope of mutant nucleophosmin (NPM1c) in complex with, or presented by, a class I major histocompatibility complex (MHC class I) protein, or cells expressing such compounds, and their use in methods for treating, or ameliorating one or more symptoms of, cancer.

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

Hematopoietic stem/progenitor cells (HSPC) and/or non-T effector cells are genetically modified to express (i) an extracellular component including a ligand binding domain that binds a cellular marker preferentially expressed on an unwanted cell; and (ii) an intracellular component comprising an effector domain. Among other uses, the modified cells can be administered to patients to target unwanted cancer cells without the need for immunological matching before administration.

ACTIVATION OF RESIDENT MEMORY T CELLS FOR CANCER IMMUNOTHERAPY
20240041996 · 2024-02-08 ·

Provided herein are methods of treating cancer by activating resident memory T cells using one or more antigenic peptides.

Genetically Modified Immune Cells Targeting NY-ESO-1 and Methods of Use Thereof
20240041928 · 2024-02-08 ·

The present disclosure provides modified immune cell (e.g., modified T cell) comprising an exogenous T cell receptor (TCR) having specificity for NY-ESO-1. The present disclosure provides modified immune cells or precursors thereof (e.g., modified T cells) comprising an exogenous TCR and a switch receptor. Gene edited modified cells are also provided, such that the expression of one or more of an endogenous T-cell receptor gene (e.g., TRAC, TRBC) or an endogenous immune checkpoint gene (e.g. PD-1 or TIM-3) is downregulated.

CARBOHYDRATE STRUCTURES AND USES THEREOF
20240042000 · 2024-02-08 ·

The present invention provides methods and compositions related to multivalent carbohydrate antigen structures comprising cancer or infection associated ganglioside carbohydrate antigens. Said carbohydrate structures may be used to induce immunity against said carbohydrate antigens. In some embodiments, carbohydrate structures may be administered to a subject thereby inducing immunity in the subject, for example, the administration of a vaccine comprising said carbohydrate structure. Also provided are methods to induce an immune response in a subject in need thereof by administering said carbohydrate structure. Further provided are methods of producing an antibody or TCR that bind said carbohydrate antigens.

METHODS AND COMPOSITIONS FOR DOSING OF ALLOGENEIC CHIMERIC ANTIGEN RECEPTOR T CELLS
20240041930 · 2024-02-08 ·

DENDRITIC CELL ACTIVATING CHIMERIC ANTIGEN RECEPTORS AND USES THEREOF

The present disclosure provides a chimeric antigen receptor (CAR) for activating dendritic cells (DCs) in an immunosuppressive tumor environment. The present disclosure also provides compositions comprising the CAR, polynucleotides encoding the CAR, vectors comprising a polynucleotide encoding the CAR, engineered cells comprising the CAR, and method using the same.

COMPOSITIONS AND METHODS FOR INHIBITION OF LINEAGE SPECIFIC ANTIGENS USING CRISPR-BASED BASE EDITOR SYSTEMS

Disclosed herein are methods of administering an agent targeting a lineage-specific cell-surface antigen, e.g., CD33 or EMR2, and a population of hematopoietic cells that are altered in the expression of the lineage-specific cell-surface antigen, e.g., CD33 or EMR2, for immunotherapy of hematological malignancies. Also disclosed herein are methods of administering an agent targeting more than one lineage-specific cell-surface antigen, and a population of hematopoietic cells that are altered in the expression of more than one lineage-specific cell-surface antigen, for immunotherapy of hematological malignancies. Cells comprising mutations in CD33, or EMR2, or more than one lineage-specific cell-surface antigen are also provided, as are methods of producing such cells using CRISPR-based base editor systems.

ANTI-CD19 ANTIBODIES AND CAR-T STRUCTURES

Anti-CD19 antibodies (e.g., UniAbs?) and CAR-T structures are disclosed, along with methods of making such antibodies and CAR-T structures, compositions, including pharmaceutical compositions, comprising such antibodies and CAR-T structures, and their use to treat disorders that are characterized by the expression of CD19.
