Immune cells leave fingerprints on tumors metastasized to the brain offering clues to future therapies

Using data from over 100,000 malignant and non-malignant cells from 15 human brain metastases, researchers have revealed two functional archetypes of metastatic cells across 7 different types of brain tumors, each containing both immune and non-immune cell types. Their findings provide a potential roadmap for metastatic tumor formation that could be used to design therapies to improve the treatment of metastasized patients.
