Targeting nerve growth factor: an Achilles' heel for tumors?

Area of Science:

• Oncology
• Immunology
• Neuroscience

Background:

• Tumor innervation, driven by the sympathetic nervous system, promotes tumor progression and immune evasion.
• Catecholamines from nerves activate tumor cell receptors, boosting growth and therapy resistance.
• Nerve growth factor (NGF) produced by tumors is crucial for innervation and a potential therapeutic target.

Purpose of the Study:

• To examine the efficacy of NGF-targeting chimeric antigen receptor (CAR) T cells.
• To investigate the impact of NGF neutralization on CAR T-cell function.
• To assess the remodeling of the tumor microenvironment by NGF-neutralizing CAR T cells.

Main Methods:

• Utilized NGF single-chain variable fragment (scFv)-secreting CAR T cells.
• Analyzed CAR T-cell function following NGF neutralization.
• Evaluated changes in the tumor microenvironment.

Main Results:

• NGF neutralization by CAR T cells impacts CAR T-cell function.
• CAR T-cell-mediated NGF neutralization can remodel the tumor microenvironment.
• Exploiting tumor-derived NGF may enhance anti-tumor immune activity.

Conclusions:

• NGF is a critical factor in tumor progression and immune escape.
• NGF-targeting CAR T cells represent a novel therapeutic strategy.
• Targeting tumor-derived survival factors can be leveraged to enhance anti-tumor immunity.
