Phylogenetic, biochemical, and genetic techniques reveal a novel and ancient member of the Perilipin family, termed Plin6, that functions to concentrate and traffic lipophilic skin pigment in teleost fish.
The ectodomain of the human polymeric Ig receptor maintains a closed triangular shape that binds and excludes bacteria in mucosa, or opens to bind and transport polymeric Ig ligands across epithelial cells.
In contrast to amniotes, zebrafish (ray-finned fish, teleost) centra are formed from specialised notochord sheath cells, and the segmental patterning of these cells is independent of the segmentation clock.
Individual social behavior results from the interaction between the individuals own oxytocin receptor genotype and the oxytocin receptor genotypes of other individuals present in its social environment.
Characterization of a novel population of enteric nervous system glial cells in zebrafish reveals their proliferative and neurogenic properties under homeostatic conditions in adults, properties difficult to model in mammals.
