Mouse macrophages contain monoamine oxidase (MAO) A activity and traces of MAO B, as judged by a strong deamination of 5-hydroxytryptamine and tyramine and a marginal one of benzylamine. Significant inhibition of MAO activity occurred in the presence of the specific inhibitors clorgyline and deprenyl. MAO A activity was considerably depressed in phagocytizing cells.
