However, little is known about neurosteroids function corresponding to specific structure and functions of the brain regions. Thus the present study analyzed localization of steroid-synthesizing enzymes in the rat and mouse olfactory bulb. RT-PCR and Western-blotting indicated the possible presence of almost all enzymes of steroid synthesis from cholesterol to estradiol, that is, cholesterol side chain cleavage enzyme (P450scc : cholesterol→pregnenolone), 3β-hydroxysteroid dehydrogenase/Δ5 - 4 isomerase (3β-HSD : pregnenolone→progesterone), 17α-hydroxylase/C17-C20lyase (P450c17 : progesterone→ androstenedione), 17β-hydroxysteroid dehydrogenase (17β-HSD : androstenedione→testosterone), 5α-reductase (5αR:testosterone→5α-dihydrotestosterone), and aromatase (testosterone→ estradiol). Immunohistochemistry confirmed that the 5α-reductase was mainly in glial cells with various immunoreactivity and co-localization pattern, but other enzymes were in bulbar neurons, and at least co-localized in mitral/tufted cells. In addition, so far analyzed, enzymatic activities of P450c17 (a key enzyme in sex steroid synthesis) and 17β-HSD were detected biochemically. These enzyme expression and activities were influenced under exposure of 17β-estradiol with various degrees. These findings indicated the presence of steroid-synthesizing activities, and thus of possible neurosteroid metabolism in the olfactory bulb.
