Brain tumors are among the most complex forms of cancer to treat. Glial cells, which support the activity of neurons in the brain, can give rise to a particularly aggressive form of cancer known as glioblastoma. Glioblastoma cells are capable of spreading through brain tissue, causing neurological symptoms that are ultimately fatal and making it difficult to develop an effective therapeutic strategy. In a recent study published in Nature Communications, an Institut Pasteur team identified two proteins that play an essential role in the migration of glioblastoma cells.
