FUKUOKA, Japan–(BUSINESS WIRE)–The Japanese Plasmalogen Society (Office: Higashi-ku, Fukuoka, Japan; President: Yutaka Oomura) announced the research results that scallop-derived plasmalogens enhanced memory and learning with the elucidation of its underlying mechanism.
Plasmalogens, a class of phospholipids, are abundant in brain, heart, skeletal muscle and immune cells. They can be extracted from various animals including scallops, chickens and sea squirts. Of particular note is that scallop-derived plasmalogens abundantly contain DHA-rich plasmalogens, thereby having higher functionality.
Key findings are as follows:
All these findings show that plasmalogens in the brain activate hippocampal neurons, and thus enhance memory.
The research team led by Dr. Takehiko Fujino, Professor emeritus of Kyushu University, previously reported* that oral ingestion of scallop-derived plasmalogens improved cognitive function in patients with mild-to-severe Alzheimer�s disease or mild cognitive impairment. This study has elucidated the mechanism underlying the effect of scallop-derived plasmalogens on memory and learning.
The findings were published in Frontiers in Cell and Developmental Biology, a leading, open-access, peer-reviewed scientific journal (Impact Factor 6.081).
