| Outline of Final Research Achievements |
Since erythrocyte contains cholesterol abundantly at the same degree as that in plasma, it is speculated that the erythrocyte is associated with cholesterol metabolism but the mechanism has not been fully elucidated. Hence, we investigated the erythrocyte-related cholesterol metabolism and its disorder. Our results demonstrated that the erythrocyte was involved in cholesterol acceptance and delivery with high-density lipoprotein (HDL) and low-density lipoprotein, and played a role in reverse cholesterol transport pathway as a cholesterol pool. In addition, we successfully produced and characterized one of dysfunctional HDL (dys-HDL), serum amyloid A-contained HDL, which is produced from liver during inflammation, in order to investigate an association between erythrocyte-related cholesterol metabolism and dys-HDL.
