Résumé

Apolipoprotein D (ApoD) is a secreted lipocalin associated with neuroprotection and lipid metabolism. Overexpression of ApoD in mouse neural tissue induces the development of a non-inflammatory hepatic steatosis in 12-month-old transgenic animals. Previous data indicates that accumulation of arachidonic acid, ApoD's preferential ligand, and overactivation of PPARγ are likely the driving forces in the development of the pathology. However, the lack of inflammation under those conditions is surprising. Hence, we further investigated the apparent repression of inflammation during hepatic steatosis development in aging transgenic animals. The earliest modulation of lipid metabolism and inflammation occurred at 6 months with a transient overexpression of L-PGDS and concomitant overproduction of 15d-PGJ
