Nose-to-Brain Delivery of Chlorella vulgaris Extracellular Vesicles for Antidepressant Effects.
Article in Journal of extracellular vesicles, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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
Current antidepressants face limitations due to the blood-brain barrier (BBB), systemic side effects and delayed onset. Here, we engineered an intranasal thermosensitive hydrogel (EVs@IN) encapsulating Chlorella vulgaris-derived extracellular vesicles (EVs) for sustained nose-to-brain delivery. EVs@IN significantly enhanced nasal mucosal retention and facilitated targeted transport of EVs to the hippocampus via olfactory pathways, while minimizing pulmonary exposure and clearance. In mouse models of depression (LPS-induced and CUMS), intranasal EVs@IN elicited rapid and potent alleviation of depressive- and anxiety-like behaviours. Mechanistically, EVs modulated astrocyte phenotypic transformation, reducing the release of neurotoxic complement C3 and suppressing neuroinflammation. Concurrently, they activated the Nrf2-Pgc-1α pathway, enhanced antioxidant defences (elevated SOD and GSH), mitigated oxidative stress and restored synaptic plasticity and neurogenesis in the hippocampus. Furthermore, we demonstrated the capacity of EVs to serve as efficient drug carriers for brain delivery. EVs@IN exhibited excellent long-term biocompatibility in vivo. Our findings establish plant-derived EVs within a sustained-release intranasal platform as a promising, scalable and BBB-bypassing strategy for the rapid treatment of depression and potentially other neuropsychiatric disorders.
