Specialization of the upper and lower olfactory rosettes reveals sex- and origin-dependent plasticity in gene expression in Senegalese sole (Solea senegalensis).
Olfaction mediates several aspects of fish behaviour, including reproduction. In Senegalese sole (Solea senegalensis), a reproductive dysfunction in captive-bred (CB) males limits the establishment of an effective artificial production system and has been linked to altered chemical communication. We performed a comprehensive RNA-seq analysis of the upper and lower olfactory rosettes of adult Seneg…

Acute Effects of Four Major Trace Amines on Zebrafish Behavioral, Neurochemical, and Neuroendocrine Responses.
Trace amines are biologically active compounds endogenously synthesized in the brain in small amounts and structurally resembling biogenic amines. Acting via specific trace amine-associated receptors (TAARs), they induce robust behavioral and physiological effects in humans and animals. However, although TAAR ligands have recently been suggested as novel putative anxiolytics, their central effects…

Evolution of Brain-Expressed Biogenic Amine Receptors into Olfactory Trace Amine-Associated Receptors.
The family of trace amine-associated receptors (TAARs) is distantly related to G protein-coupled biogenic aminergic receptors. TAARs are found in the brain as well as in the olfactory epithelium where they detect biogenic amines. However, the functional relationship of receptors from distinct TAAR subfamilies and in different species is still uncertain. Here, we perform a thorough phylogenetic ana…

Spermine in semen of male sea lamprey acts as a sex pheromone.
Semen is fundamental for sexual reproduction. The non-sperm part of ejaculated semen, or seminal plasma, facilitates the delivery of sperm to the eggs. The seminal plasma of some species with internal fertilization contains anti-aphrodisiac molecules that deter promiscuity in post-copulatory females, conferring fitness benefits to the ejaculating male. By contrast, in some taxa with external ferti…

Crypt cells are involved in kin recognition in larval zebrafish.
Zebrafish larvae imprint on visual and olfactory kin cues at day 5 and 6 postfertilization, respectively, resulting in kin recognition later in life. Exposure to non-kin cues prevents imprinting and kin recognition. Imprinting depends on MHC class II related signals and only larvae sharing MHC class II alleles can imprint on each other. Here, we analyzed which type of olfactory sensory neuron (OSN…

Genome-wide identification, expression analysis of taars (trace amine-associated receptors) and response to cadaverine and putrescine in Mandarin fish (Siniperca chuatsi).
The unique feeding behavior of Siniperca chuatsi (S. chuatsi), which exclusively consumes live fry and rejects dead fry, severely limits the development of its aquaculture industry. This rejection of dead fry likely stems from an aversion to necromones (death-associated odors). Although a subset of trace amine-associated receptors (TAARs) containing key conserved residues (Asp3.32 and/or Asp5.42) …

Structural basis of amine odorant perception by a mammal olfactory receptor.
Odorants are detected as smell in the nasal epithelium of mammals by two G-protein-coupled receptor families, the odorant receptors and the trace amine-associated receptors1,2 (TAARs). TAARs emerged following the divergence of jawed and jawless fish, and comprise a large monophyletic family of receptors that recognize volatile amine odorants to elicit both intraspecific and interspecific innate be…

Convergent olfactory trace amine-associated receptors detect biogenic polyamines with distinct motifs via a conserved binding site.
Biogenic amines activate G-protein-coupled receptors (GPCRs) in the central nervous system in vertebrate animals. Several biogenic amines, when excreted, stimulate trace amine-associated receptors (TAARs), a group of GPCRs in the main olfactory epithelium, and elicit innate behaviors. How TAARs recognize amines with varying numbers of amino groups is largely unknown. We reasoned that a comparison …

Cadaverine and Spermine Elicit Ca2+ Uptake in Human CP Cells via a Trace Amine-Associated Receptor 1 Dependent Pathway.
The choroid plexus (CP) constitutes a barrier between the blood and the cerebrospinal fluid (CSF) which regulates the exchange of substances between these two fluids through mechanisms that are not completely understood. Polyamines as spermine, spermidine and putrescine are produced by all cells and are present in the CSF. Interestingly, their levels are altered in some neuronal disorders as Alzhe…

Trace Amines and Their Receptors.
Trace amines are endogenous compounds classically regarded as comprising β-phenylethyalmine, p-tyramine, tryptamine, p-octopamine, and some of their metabolites. They are also abundant in common foodstuffs and can be produced and degraded by the constitutive microbiota. The ability to use trace amines has arisen at least twice during evolution, with distinct receptor families present in invertebra…
