Abstract (original English)
Background: Pancreatic ductal adenocarcinoma (PDAC) typically develops without symptoms, and its aggressive progression combined with late-stage diagnosis underscores the critical need for improved early detection strategies. Circulating tumor cells (CTCs) in blood are potential biomarkers for PDAC. In this study, the detection of pancreatic cancer-associated CTCs was evaluated using two magnetic-based diagnostic systems in a comparative approach. Methods: Two distinct nanotheranostic platforms were developed: monoclonal antibody-conjugated magnetic nanoparticles (mAbs-MNPs) and magnetized exosomes (termed Magxosomes). Anti-mesothelin and anti-vimentin were used as monoclonal antibodies, while mesenchymal stem cells (MSCs) treated with MNPs served as the source of Magxosomes. Characterization of nano-systems was performed using dynamic light scattering (DLS), inductively coupled plasma mass spectrometry (ICP-MS), nanoparticle tracking analysis (NTA), and transmission electron microscopy (TEM). Blood samples were collected from pancreatic cancer mouse models, treated with nanotheranostic platforms, and analyzed using a homemade magnetic particle spectroscopy (MPS) device. Results: The detection of pancreatic cancer-associated CTCs was investigated using nanotheranostic platforms alongside an MPS instrument. In this context, the mAbs-MNPs systems demonstrated varying efficiencies
