The results obtained in Brockmann bodies (BB, main accumulation of pancreatic endocrine cells in this species) also suggested the presence of components of putative fatty acid sensing systems based on fatty acid metabolism and binding to FAT/CD36 [14], which could be related to insulin release since hyperinsulinemia has been demonstrated in fish after increasing circulating FA levels [15]. Here, CD36 is linked to Hyperinsulinemia.
