Summary

Story summary

Researchers at the Icahn School of Medicine at Mount Sinai found that lung tumors influence immune cells in the bone marrow before they reach the tumor.
This involves a "first hit" that skews myeloid progenitor cells toward pro-cancer roles, followed by a "second hit" at the tumor site.
Targeting the NRF2 protein may prevent immune suppression, improving immunotherapy outcomes.
The study indicates potential blood tests for early detection of immune dysregulation in lung cancer.
Future research will investigate similar mechanisms in other cancers and chronic inflammatory diseases.
