Virus-like particles provide vital clues about brain tumors

Exosomes are small, virus-like particles that can transport genetic material and signal substances between cells. Researchers at Lund University, Sweden, have made new findings about exosomes released from aggressive brain tumors, gliomas. These exosomes are shown to have an important function in brain tumor development, and could be utilized as biomarkers to assess tumor aggressiveness through a blood test.
