Plasmalogens (Pls) are bioactive substances enriched in the brain with a regulatory effect on Alzheimer's disease (AD), while their metabolomic influence accompanying AD and the underlying mechanisms remain unclear. Here, we extracted and purified Pls (purity of ≥90%) from mussels and applied unbiased metabolomics using ultraperformance liquid chromatography Q-Exactive Orbitrap mass spectrometry to analyze the variation of metabolites in the major metabolic pathways of AD and revealed the cognitive improvement effect of Pls using an experimental AD zebrafish model. The results showed that 37 differential endogenous metabolites were identified, among which glycerophosphocholine, choline, -adenosylmethionine (SAM), l-glutamine, linoleic acid, 9(S)-HPODE, methionine, and creatine were the major abnormally regulated metabolites, and the first four metabolites were viewed as potential endogenous markers. This study suggested that systemic metabolic profiling could reveal the potential metabolic networks of AD and illuminated the protective effect of Pls on AD through biochemistry mechanisms and metabolic pathways.

Tyramine, β-phenylethylamine, octopamine and other trace amines are endogenous substances recently recognized as important novel neurotransmitters in the brain. Trace amines act via multiple selective trace amine-associated receptors (TAARs) of the G protein-coupled receptor family. TAARs are expressed in various brain regions and modulate neurotransmission, neuronal excitability, adult neurogenesis, cognition, mood, locomotor activity and olfaction.

All three phases of kidney development utilize epithelized tubules called nephrons, which function to take in filtrate from the blood or coelom and selectively reabsorb solutes the organism needs, leaving waste products to be excreted as urine. The pronephros are heavily studied in aquatic organisms such as zebrafish and Xenopus, as they develop quickly and are functional.
