An international team of scientists was able to detect small protein fragments (peptides) from bacteria that are presented to the immune system by brain tumors on the cell surface. "The bacterial peptides are not only presented, they are also recognized by the immune system and trigger an immune response against the tumor," says PD Dr. Marian Christoph Neidert, deputy chief physician at the Department of Neurosurgery at the Cantonal Hospital St.Gallen and one of the leaders of this research project. The groundbreaking new findings could be published in the prestigious journal Nature. Link to the publication.
