Intermediärfilament- und GD2-Expression in astrozytären Hirntumoren
In der Arbeit wird eine vergleichende, semiquantitative immunhistochemische Untersuchung der Expression von saurem Gliafaserprotein, Vimentin und Glykosphingolipid GD2 in 28 astrozytären Hirntumoren WHO Grad II-IV dargestellt. Statistisch findet sich eine hohe Korrelation sowohl der intrazellulären...

By means of immunhistochemical markers the expression of glial fibrillary acidic protein, vimentin and glykosphingolipid GD2 is investigated in 28 astrocytic tumors grading WHO II-IV. Statistically, there is found a high correlation in the cytoplasmatic expression of GFAP/GD2 as well as Vimentin/GD2 and GFAP/Vimentin.The semiquantitatively strongest expression was found in gemistocytic and protoplasmatic cells of the investigated glial tumors. As conclusion, astrocytic tumors express in a similar way intermediary filament GFAP and glykosphingolipid GD2. Whether or not a co-localisation of intermediary filaments and GD2 within the brain tumors takes place, remains open.
