The present study investigated the in vitro effects on caprine monocytes of two ω-3 PUFAs, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on lipid droplet formation, an emerging process of fundamental importance in innate immunity regulation. The mRNA abundance of PAT protein family (PLIN1, PLIN2 and PLIN3), involved in the formation and trafficking of the droplets, was also assessed. The effects of EPA and DHA on monocyte apoptosis were studied as well. The number of lipid droplets per cell was found to be dependent on both type and concentration of fatty acid. ω-3 PUFAs upregulated PLIN3 and PLIN2 gene expression, as well as apoptosis rate. The present findings suggest that PUFA might modify innate immune functions of goat monocytes by interfering with the formation of lipid droplets and by upregulating proteins belonging to PAT protein family.
