Migrasome-propagated ITGβ3-TGFβ1 circuit orchestrates breast cancer brain metastasis by reprogramming the microglial niche.
OBJECTIVE The dismal prognosis of breast cancer brain metastasis (BCBM) is attributed to a maladapted tumor microenvironment. This study was aimed at deciphering the role of novel intercellular communicators, tumor-derived migrasomes, in driving BCBM progression, with a focus on their ability to co-opt brain-resident m...
