EGFR and central nervous system cancer: Recently, Kuo and Liang used innovative catanionic solid lipid nanoparticles (CASLNs) prepared in microemulsions carrying carmustine (BCNU) (BCNU-CASLNs) that were grafted with antiepithelial growth factor receptor (EGFR) (anti-EGFR/BCNU-CASLNs) and applied to inhibit the propagation of human brain malignant glioblastomas cells due to gliomas normally express certain types of growth factor receptor.
