Odorant receptor proteins in the mouse main olfactory epithelium and olfactory bulb
In the mouse, odorant receptor proteins (ORs) are G-protein-coupled receptors expressed in mature olfactory sensory neurons (OSNs) of the main olfactory epithelium (MOE). ORs mediate odorant reception at the level of the OSN cilia. Most of the ∼1100 OR genes in the mouse genome are expressed, at the RNA level, in mature OSNs. The literature on antibodies against ORs is limited, and most reports...
متن کاملOdorant receptor specificities and receptor combinatorials: implications for olfactory coding.
The perception and discrimination of thousands of different odorants by the vertebrate olfactory system results from the activation of specific olfactory neurons within the olfactory epithelium of the nose (reviewed in Buck, 2000; Firestein, 2001). Activity from these cells is then interpreted by the brain to discern the molecular identity of a given odorant stimulus. How is this process of mol...
متن کاملActivity-Dependent Modulation of Odorant Receptor Gene Expression in the Mouse Olfactory Epithelium
Activity plays critical roles in development and maintenance of the olfactory system, which undergoes considerable neurogenesis throughout life. In the mouse olfactory epithelium, each olfactory sensory neuron (OSN) stably expresses a single odorant receptor (OR) type out of a repertoire of ∼1200 and the OSNs with the same OR identity are distributed within one of the few broadly-defined zones....
متن کاملOdorant-induced olfactory receptor neural oscillations and their modulation of olfactory bulbar responses in the channel catfish.
Peripheral waves (PWs) in the channel catfish are odorant-induced neural oscillations of synchronized populations of olfactory receptor neurons (ORNs) that appear after the initial approximately 500 msec of the response. The mean dominant frequency during the initial 2 sec of PW activity is approximately 28 Hz, declining to approximately 20 Hz in the last sec of a 5 sec stimulus. Recordings of ...
متن کاملOdorant receptor expression patterns are restored in lesion-recovered rat olfactory epithelium.
Lesions of the olfactory periphery provide a means for examining the reconstitution of a diverse and highly regulated population of sensory neurons and the growth, en masse, of nascent axons to the bulb. The olfactory epithelium and its projection onto the bulb are reconstituted after ablation by methyl bromide gas, and some measure of olfactory function is restored. The extent to which the sys...
