GNRH1 and posterior cortical atrophy: Ahmed et al. developed multifunctional double-receptor-targeting IONPs [luteinizing hormone-releasing hormone (LHRH) peptide- and AE105 peptide-targeted IONPs, LHRH-AE105-IONPs] that simultaneously targeted the LHRH receptor (LHRH-R) and uPAR and exhibited a significant MRI contrast in PCa cells.
