Deciphering the Dialogue between Brain Tumors, Neurons, and Astrocytes.

ABSTRACT: Glioblastoma and brain metastases from peripheral tumors account for most cases of tumors in the central nervous system while also being the deadliest. From a structural point of view, malignant brain tumors are classically characterized by hypercellularity of glioma and vascular endothelial cells. Given these atypical histologic features, glioblastoma and brain metastases have long been considered as "foreign" entities with few to no connections to the brain parenchyma. The identification of intricate connections established between glioblastoma cells and the brain parenchyma paired with the ability of peripheral metastatic cells to form functional synapses with neurons challenged the concept of brain tumors disconnected from the central nervous system.
