Résumé
Cationic cholesteryl-group-bearing pullulan nanogel (cCHP-nanogel) is an effective drug-delivery system for nasal vaccines. However, cCHP-nanogel-based nasal vaccines might access the central nervous system due to its close proximity via the olfactory bulb in the nasal cavity. Using real-time quantitative tracking of the nanogel-based nasal botulinum neurotoxin and pneumococcal vaccines, we previously confirmed the lack of deposition of vaccine antigen in the cerebrum or olfactory bulbs of mice and non-human primates (NHPs), rhesus macaques. Here, we used positron emission tomography to investigate the biodistribution of the drug-delivery system itself, cCHP-nanogel after mice and NHPs were nasally administered with
