Abstract
Cold exposure produces a large increase in rat brown adipose tissue (B AT) dopamine (DA) content. This increase is rapid (30 min of cold are sufficient to produce a maximal effect), and can be detected at differ ent ages (from birth to adulthood). Cold also greatly increases DA tur nover rate in BAT. In the same experimental conditions tyrosine hydrox ylase is activated, while the activity of dopamine-beta-hydroxylase is not modified. The possibility that DA can regulate BAT functioning is discussed.
