Abstract

Provided herein are methods for stimulating an immune response to a target cell population or a target tissue in a subject by administering to the subject a composition comprising an amphiphilic ligand conjugate. Such an amphiphilic ligand conjugate can comprise a lipid, one or more cargos (e.g., a CAR ligand, a chimeric cytokine receptor target, a chimeric co-stimulation receptor target, a synNotch receptor target), and optionally a linker.

Claims (10)

1. A method of stimulating an immune response to a target cell population or a target tissue in a subject, the method comprising administering a composition to the subject, wherein the composition comprises an amphiphilic ligand conjugate comprising a lipid, a chimeric antigen receptor (CAR) ligand, and a polar block linker that couples the lipid to the CAR ligand,

wherein the lipid is 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE), the linker is a polyethylene glycol (PEG) linker, the CAR ligand is fluorescein isothiocyanate (FITC),

wherein the subject comprises an immune cell comprising a CAR,

wherein the CAR comprises an extracellular domain comprising a target-binding domain that binds to FITC,

wherein the immune cell is a B cell, a natural killer (NK) cell, a macrophage, a neutrophil, a dendritic cell, a mast cell, an eosinophil, a basophil, or a tumor infiltrating lymphocyte (TIL), and

wherein the immune cell is not a T cell.

2. The method of claim 1 , wherein the CAR further comprises a transmembrane domain and an intracellular signaling domain.

3. The method of claim 2 , wherein the CAR further comprises one or more co-stimulatory domains.

4. The method of claim 1 , wherein the composition further comprises an adjuvant, wherein the adjuvant is an amphiphilic oligonucleotide conjugate comprising an immunostimulatory oligonucleotide conjugated to a lipid, with or without a linker, and optionally a polar compound.

5. The method of claim 1 , wherein the amphiphilic ligand conjugate binds albumin under physiological conditions.
