Chemokine-receptor

Mechanisms

Targets

Refs

CXCL8-CXCR1/2

Co-expression of the matched chemokine receptor CXCR2 in CAR T-cells results in increased migration

Integrin αvβ6

[51]

Hepatocellular carcinoma tumors express high level of CXCR2 ligands and CXCR2 expression endowed CAR-T cells with improved trafficking ability and enhanced tumor accumulation

Glypican-3

[117]

Radiation-induced CKCL8 release from the tumor can enhance intratumoral CXCR1 or CXCR2 modified CAR-T cells trafficking

CD70

[52]

CCL2-CCR2

High concentration of CCL2 recruits CCR2 expressing CAR-T cells

Mesothelin
