چکیده انگلیسی
Though its function remains obscure, olfactory marker protein (OMP) has been implicated in olfactory transduction and the enhancement of neurogenesis within olfactory epithelium. Here we show, using Western blot analysis and immunocytochemistry, that unilateral naris occlusion (UNO) on postnatal day 1 alters OMP immunoreactivity (IR) differentially on the occluded and non-occluded sides of the nasal cavity in 18, 24 and 70-day-old mice. Compared to untreated animals, UNO-treated animals had a decrease in OMP-IR in olfactory receptor neurons on the non-occluded side and an increase in OMP-IR in olfactory receptor neurons on the occluded side of the nasal cavity. These results suggest that OMP concentration is up- or down-regulated depending on the amount of odor stimulation olfactory receptor neurons receive. It is proposed that this apparent change in protein concentration may be part of a more general compensatory response by olfactory neurons to levels of odor in the environment.
