FOLH1 and carcinoma: Several other molecular targets ought to be mentioned: interleukin receptors expressed, particularly, in some types of gliomas [205]; mesothelin which is involved in cell adhesion and is highly expressed on mesothelioma cells and in a number of adenocarcinomas [206,207]; prostate-specific membrane antigen PSMA [208,209]; plasma membrane proteoglycans, for example the mucin (MUC-1) overexpressed in carcinomas [210,211].
