Immune Cells in Cerebrospinal Fluid Predict Response of Brain Metastasis to Immunotherapy


Immune Cells in Cerebrospinal Fluid Predict Response of Brain Metastasis to Immunotherapy
March 9, 2021
Studies by researchers at the Vall d’Hebron Institute of Oncology (VHIO), and the National Centre for Genomic Analysis-Centre for Genomic Regulation (CNAG-CRG), Barcelona, have demonstrated how immune cells that access the cerebrospinal fluid (CSF) of patients with brain metastases faithfully recapitulate the characteristics of the brain tumor immune cells, and could represent novel biomarkers of response to immune checkpoint inhibitor (ICI) therapy.
The team used single-cell RNA sequencing combined with T cell receptor genotyping to characterize immune cells in brain lesions and matched CSF. The single-cell profiling allowed them to chart the major cell types and transient tumor-sepcific states in the brain metastasis (BrM) tumor microenvironment (TME). Describing their results in ....

Immune cells accessing cerebrospinal fluid recapitulate the characteristics of cells identified in brain metastasis, and could therefore constitute novel biomarkers of response to immune-based therapies, as per the study in
Nature Communications, led by Joan Seoane, Director of Preclinical and Translational Research co-program at VHIO and ICREA Professor.
Immune checkpoint inhibitors including anti-PD1, anti-PD-L1, and anti-CTLA4, have shown significant clinical benefits in patients with progressive or metastatic solid tumors, including some brain metastasis.
Notably, these immune-based therapies have improved outcomes for some of those suffering from lung cancer and melanoma. Together, these tumor types (represent between 30-40% of all cancers), along with breast cancer, are three common malignancies that lead to brain metastases. ....
