ICOS‐ImmunoPET Monitors T Cell Activation After Combination Immune Checkpoint Blockade in a Mouse Model of Melanoma Brain Metastasis
ABSTRACT Immune checkpoint inhibitors (ICIs) have transformed outcomes for melanoma brain metastases (MBM), yet early response assessment remains challenging because currently available tools such as magnetic resonance imaging (MRI) lack molecular specificity and are confounded by pseudoprogression. Antibody‐based posi...
