| Outline of Final Research Achievements |
It is established that lysophospholipids constitute a new family of lipid mediators and are involved in a broad range of (patho)physiological actions. We have examined the involvement of lysophosphatidic acid (LPA), sphingosine 1-phosphate (S1P), and lysophosphatidylserine (LysoPS) in human diseases and pursued the clinical introduction of the measurement of these lysophospholipids and their related proteins; LPA, S1P, LysoPS are the most well characterized lysophospholipids. Autotaxin (ATX) reflects the LPA level in vivo, and ATX assay kit is promising as an IVD kit. Furthermore, the minor apolipoprotein ApoM is the carrier of S1P and can be a surrogate marker of S1P while phosphatidylserine-specific phospholipase A1 (PS-PLA1), which produces LysoPS, can be a biomarker reflecting the in vivo action of LysoPS. We have succeeded in the establishment of the assay systems not only for ATX but also for ApoM and PS-PLA1, and revealed the clinical importance of their measurements.
