Abstract

The present invention includes compositions and methods for treating atherosclerosis. In certain embodiments, atherosclerosis is treated using a chimeric antigen receptor (CAR) T cell specific for modified low-density lipoprotein.

Claims (30)

1 . An isolated chimeric antigen receptor (CAR) comprising an antigen binding domain specific for modified low-density lipoprotein (LDL), a transmembrane domain, and an intracellular domain, wherein the antigen binding domain comprises an scFv comprising the amino acid sequence set forth in SEQ ID NO: 6.

2 . The isolated CAR of claim 1 , wherein the modified LDL comprises oxidized LDL (OxLDL).

3 . The isolated CAR of claim 1 , wherein the modified LDL comprises an MDA/MDA-ApoB100 epitope present on oxidized LDL (OxLDL).

4 . The isolated CAR of claim 1 , wherein the modified LDL comprises modified ApoB100.

5 . The isolated CAR of claim 1 , wherein the modified LDL is selected from the group consisting of Cu-oxidized LDL, advanced glycation end products LDL (AGE-LDL), malondialdehyde-LDL, glycated-LDL, carbamylated LDL, desialylated LDL, apolipoprotein (a), and lipoprotein (a) (Lp-a), oxidized phosphatidylcholine containing oxidized phospholipids, 1-palmitoyl-2-(5-oxovaleroyl)-sn-glycero-3-phosphocholine (POVPC), oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine (OxPAPC), 4-hydroxynonenal (HNE), oxidized cholesteryl ester (OxCE), and oxidized cardiolipin (OxCL).

6 . The isolated CAR of claim 1 , wherein the transmembrane domain is selected from the group consisting of CD28, CD8α, ICOS, and GITR.

7 . The isolated CAR of claim 1 , wherein the transmembrane domain comprises an amino acid sequence selected from the group consisting of SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 13, and SEQ ID NO: 14.

8 . The isolated CAR of claim 1 , wherein the intracellular domain is at least one selected from the group consisting of CD3zeta, CD28, 4-1BB, ICOS, GITR, and CD2.

9 . The isolated CAR of claim 1 , wherein the intracellular domain comprises an amino acid sequence selected from the group consisting of SEQ ID NO: 15, SEQ ID NO: 18, SEQ ID NO: 20, SEQ ID NO: 22, and SEQ ID NO: 23.

10 . The isolated CAR of claim 1 , wherein the intracellular domain comprises an amino acid sequence selected from the group consisting of SEQ ID NO: 24, and SEQ ID NO: 26.

11 . The isolated CAR of claim 1 , wherein the CAR further comprises a hinge domain.

12 . The isolated CAR of claim 1 , wherein the CAR further comprises a hinge domain comprising SEQ ID NO: 8.

13 . The isolated CAR of claim 1 , wherein the CAR comprises a 2D03 scFv, a CD8 α hinge domain, a CD28 transmembrane domain, a CD28 intracellular domain, and a CD3 zeta domain.

14 . The isolated CAR of claim 1 , wherein the CAR comprises a 2D03 scFv, a CD8α hinge domain, a CD8α transmembrane domain, a 4-1BB intracellular domain,

and a CD3 zeta domain.

15 . The isolated CAR of claim 1 , wherein the CAR comprises the amino acid sequence of SEQ ID NO: 2.

16 . The isolated CAR of claim 1 , wherein the CAR comprises a 2D03 scFv, a CD8α hinge domain, an ICOS transmembrane domain, an ICOS intracellular domain, and a CD3 zeta domain.

17 . The isolated CAR of claim 1 , wherein the CAR comprises the amino acid sequence of SEQ ID NO: 3.

18 . The isolated CAR of claim 1 , wherein the CAR comprises, a 2D03 scFv, a CD8α hinge domain, a GITR transmembrane domain, a GITR intracellular domain, and a CD3 zeta domain.

19 . The isolated CAR of claim 1 , wherein the CAR comprises the amino acid sequence of SEQ ID NO: 4.

20 . The isolated CAR of claim 1 , wherein the CAR comprises a 2D03 scFv, a CD8α hinge domain, a CD8α transmembrane domain, a CD2 intracellular domain, and a CD3 zeta+domain.
