Special Issue Information

Dear Colleagues,

Delivery of drugs and genes targeting the brain represents a remarkable challenge due to the blood–brain barrier (BBB). Overcoming this barrier via the nasal route has emerged as an important non-invasive method for nose-to-brain delivery. Nasal delivery has also provided access to systemic or targeted organs. In this sense, different strategies have been developed to enhance targeted drug delivery via the nasal route, focusing on designing pharmaceutical vectors that interact effectively with nasal mucosa. These strategies may include nanotechnology-based drug encapsulation, protection, or target systems, mucoadhesive polymers to enhance mucoadhesion and prolong drug contact, and permeation enhancers to improve drug penetration across the nasal epithelium. Consequently, the development of effective nasal delivery systems remains a significant challenge in the field of controlled drug targeting and delivery.

This Special Issue aims to highlight recent advancements in developing vectors for drug and gene delivery delivered via the nasal route.

The nasal route represents a promising non-invasive technique for the direct delivery of nucleic acids to the central nervous system (CNS) disorders, effectively bypassing the blood–brain barrier. This route offers several advantages, including ease of administration, enhanced patient compliance, rapid therapeutic onset, and increased availability. Nonetheless, challenges such as mucociliary clearance, enzymatic degradation, and the low permeability of cell membranes to large molecules remain obstacles to the effectiveness of this approach. To address these limitations and achieve targeted nose-to-brain delivery with optimized therapeutic outcomes, various technological solutions have been explored, such as nanotechnology-based delivery systems and mucoadhesive formulations. These innovations aim to enhance the permeability of the nasal mucosa, extend the residence time of therapeutic agents in the nasal cavity, and improve overall treatment effectiveness. While the nasal gene delivery to the brain is still relatively new, it holds considerable potential for expanding treatment options for a range of CNS disorders. In this context, this review examines the anatomy and physiology of the nasal route, the mechanisms of biomolecule transport from nose to brain, the potential of gene delivery vectors, key preclinical advancements, and clinical perspectives for the nasal delivery of nucleic acids in CNS disorders.
