Seabuckthorn (Hippophae rhamnoides L.) is known for its medicinal properties in treating various diseases, including neurological conditions. However, the therapeutic effect of inhaled seabuckthorn seed oil (SSO) on Alzheimer's disease (AD) remains not fully understood. This study explores the effects of nebulized inhalation of SSO in 9-month-old APP/PS1 mice over 21 days. The results showed that nebulized SSO improved memory and cognition. Using 7.0T MRI to monitor blood oxygenation level dependent (BOLD) signals revealed that SSO altered the Amplitude of Low Frequency Fluctuations (ALFF) and Regional Homogeneity (ReHo) signaling such as in the amygdala and substantia innominate, and hippocampus. Enzyme-linked immuno sorbent assay (ELISA) and pathological analyses indicated reduced neuroinflammation in plasma and brain, decreased neuronal necrosis, lower β-amyloid (Aβ) protein levels, reduced amyloid deposition, and increased tyrosine hydroxylase activity. Additionally, SSO promoted gut microbiota remodeling by increasing alpha diversity and boosting levels of probiotics such as Verrucomicrobia, Bifidobacterium, Prevotella, and Akkermansia, without adverse effects on lung tissue. Nebulized inhalation of SSO may slow AD progression by modulating inflammation and amyloid deposition. Nebulized inhalation offered a potential method for enhancing drug delivery across the blood-brain barrier with reduced systemic side effects.

We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections.
Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021).
•Engineering
Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live.
•Physical sciences
Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics.
•Earth and environmental sciences
Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems.
•Biological sciences
Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants.
•Health sciences
The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
