NEUROCALCIN IMMUNOREACTIVITY IN RAT OLFACTORY-BULB

Neurocalcin, a newly discovered calcium-binding protein belonging to t he recovering-like superfamily, was detected immunohistochemically in tufted cells from the rat olfactory bulb. More precisely, only periglo merular tufted cells and some tufted cells from the external plexiform layer were expressing neurocalcin. Western blot analysis has confirme d the presence of neurocalcin in rat olfactory bulb. Lack of neurocalc in immunoreactivity in mitral cells and periglomerular cells favor a d ifferent phylogenic origin between tufted and mitral or periglomerular cells.
