Micro/Nanoparticles in the Nose-Brain Axis: Implications for Pathogenesis and Therapeutic Interventions.
Review in International journal of nanomedicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The nose-brain axis (NBA) is a crucial bidirectional deliverypathway between the nasal cavity and the central nervous system (CNS) that influences both neurophysiology and disease progression. In addition to serving as a route for drug delivery, the NBA plays an active role in neurological disorders by mediating inflammatory responses, microbial interactions, and environmental exposure. Emerging evidence suggests that the NBA may be mechanistically relevant to CNS disorders, particularly within neurodegeneration frameworks such as the Braak and dual-hit hypotheses, which emphasize early olfactory or other peripheral involvements. This review explores how micro/nanoparticles interact with the NBA, not only as therapeutic carriers but also as factors contributing to neuroinflammation and neurodegeneration. Pathogenic micro/nanoparticles, including environmental pollutants and industrial nanoparticles, have been implicated in the exacerbation of CNS disorders by triggering oxidative stress and immune activation in both nasal and brain tissues. Conversely, therapeutic micro/nanoparticles such as biomimetic, synthetic, and cell-derived formulations represent promising strategies for modulating neuroinflammation, enhancing neuroprotection, and restoring CNS function through nasal-targeted interventions. However, substantial gaps remain in the existing understanding of the influences of nasal immune responses, microbiota, and barrier integrity on CNS health through the NBA. Addressing these challenges is critical for leveraging micro-/nanoparticles for the prevention and treatment of CNS diseases.
