For the first time a typical paediatric tumor (medulloblastoma) was screened with SEREX (serological definition of recombinantly expressed antigens) and proved as an efficiency method in paediatric oncology. SEREX-method identifies antigens which have activate CD4+ cells in patients. In this way seven clons were identified, which have been reactive in serum of patients, with four different cDNA-inserts. With this new identified antigenspecific Ak a use as tumour marker or with tumour antigen MU-MB-2.42 as a point of attachment for vaccination strategy is suggested.
