CALRETININ, CALBINDIN-D28K AND PARVALBUMIN-LIKE IMMUNOREACTIVITY IN MOUSE CHEMORECEPTOR NEURONS

Calretinin immunoreactivity was demonstrated in adult mouse olfactory receptor neurons and in the vomeronasal and septal chemoreceptor neuro ns, whereas parvalbumin expression was restricted to the vomeronasal r eceptor neurons. Calbindin-D28k-like immunoreactivity was primarily lo calized in the vomeronasal and septal chemoreceptor neurons although a n occasional neuronal staining with calbindin-D28k was also found in r estricted areas of the main olfactory epithelium.
