Monoaminorum oxidasis B
Monoaminorum oxidasis B (abbreviatura MAO-B) est unum ex duobus isoenzymis monoaminorum oxidasis (OMIM: 309860). Nomen chromosomate X locati geni est MAOB.
Natura MAO-B
recensereGenum MAOB in chromosomate X (Xp11.3) locatum est. In cerebro humano MAO-B praecipue in cellulis nervorum systematis serotonergici atque nucleis raphes (et dorsalibus et medianis) inventum est[1]. Enzymum MAO-B in thrombocytis quoque exprimuntur.
Effectus MAO-B
recensereEnzym hoc decompositionem dopamini perficit. Inhibito igitur enzymi multitudinem dopamini augeat.
Inhibitores MAO-B
recensereInhibitores sunt Rasagilinum, Safinamidum[2], Selegilinum. Fumatio quoque MAO-B inhibit[3].
