Neural checkpoint therapy in lung cancer.
Nerve cells near tumors suppress immune responses through a newly identified mechanism, suggesting nerve-blocking strategies could enhance immunotherapy.
This perspective in Trends in Cancer highlights a newly identified mechanism by which Nav1.8+ nociceptive neurons expressing CGRP impair anti-tumor immunity in lung adenocarcinoma by disrupting tertiary lymphoid structure formation, proposing neural checkpoint blockade as a novel complementary approach to existing immunotherapy. The concept of targeting tumor innervation to improve immune activation represents a paradigm-shifting hypothesis warranting preclinical and early clinical investigation.

Why it surfaced
Novel neural checkpoint concept—Nav1.8+/CGRP axis as immune regulator in lung adenocarcinoma—offers a new therapeutic lever distinct from PD-1/PD-L1; perspective supported by mechanistic evidence in a major cancer type.
