title: Neuroblastomas and medulloblastomas exhibit more Coxsackie adenovirus receptor expression than gliomas and other brain tumors.
abstract: Adenoviral vector-mediated treatment is a potential therapy for tumors of the central nervous system. To obtain a significant therapeutic effect by adenoviral vectors, a sufficient infection is required, the power of which depends predominantly on the level of Coxsackie adenovirus receptors. We stained surgical biopsies of central nervous system tumors and neuroblastomas for Coxsackie adenovirus receptors. For gliomas, the level of the receptor was low and markedly variable among individual tumors. By contrast, neuroblastomas and medulloblastomas exhibited a higher degree of Coxsackie adenovirus receptor expression than gliomas and other brain tumors. We conclude that neuroblastomas and medulloblastomas could be suitable for adenovirus-mediated gene therapy. Adverse effects of the treatment, however, must be considered because neurons and reactive astrocytes also express a significant amount of the receptor.
