Abstract
The olfactory neurons of vertebrates, including teleosts, regenerate through adult life. This ability seems to depend partially on neurotrophic factors, which include some neurotrophins, mainly nerve growth factor (NGF), and their cognate Trk receptors. Zebrafish is an ideal model for studying neurogenesis in the olfactory system, but what kinds of olfactory sensory neurons (ciliated, microvillous or crypt neurons) are under the control of neurotrophins during adult life is unknown. Here we examined the expression of Trk proteins in the olfactory epithelium of adult zebrafish using immunohistochemistry. TrkA-like immunoreactivity was the only Trk detected, and it was restricted to the somata of crypt sensory neurons, their central processes being apparently unreactive. These results provide indirect evidence for a possible role of NGF-like molecules (i.e. neurotrophin-6 and neurotrophin-7) in the peripheral olfactory system of adult zebrafish, acting on TrkA-like receptor expressing crypt neurons. It remains to be established whether or not TrkA-like receptors and their ligands play a function in the neurogenesis or differentiation of these cells.
