The interactions of neurotrophins with the Trk family of tyrosine kinase receptors result in growth and maturational changes in neuronal cells. Although the histogenesis of brain tumors composed of mature neuronal cells is still not completely understood, neurotrophins and Trk receptors may be
The central neurocytoma, a recently identified rare supratentorial brain tumor in young adults, is characterized by intraventricular location and a usually benign clinical course. In order to elucidate the histogenesis and differentiation potential of this neoplasm, we have undertaken an
The FGFR1 gene encoding fibroblast growth factor receptor 1 has emerged as a frequently altered oncogene in the pathogenesis of multiple low-grade neuroepithelial tumor (LGNET) subtypes including pilocytic astrocytoma, dysembryoplastic neuroepithelial tumor (DNT), rosette-forming glioneuronal tumor
The discovery of fibroblast growth factor receptor (FGFR) gene family alterations as drivers of primary brain tumors has generated significant excitement, both as potential therapeutic targets as well as defining hallmarks of histologic entities. However, FGFR alterations among neuroepithelial
