title: Modification of theophylline-induced lipolysis in human fat cells after trypsination.
abstract: Trypsin-treatment of human fat cells results in the potentiation of the lipolytic response and the cAMP accumulation induced by theophylline (5 . 10(-4) M) but not of those induced by theophylline (5 . 10(-3) M). The amount of cAMP formed after exposure to theophylline (5 . 10(-3) M) plus norepinephrine (5 . 10(-6) M) remains, however, 2.6 fold higher in trypsin-treated human fat cells than in the control ones.
