General advantages and molecular features of zebrafish in translational pain research. As a vertebrate species, the zebrafish shows a high genetic and physiological homology when compared to mammals, but present a low cost of maintenance and feasibility to high-throughput screens similar to invertebrates (left). Molecular correspondece of the receptors involved in pain responses in humans with their respective genes in zebrafish (right). # are absent in zebrafish. *are splice variants.
