title: [Mechanism of the appearance of nuclear inclusions with microfilaments and microtubules in sympathetic neurons. Influence of dibutyryl-adenosine 3'-5' monophosphate and theophylline].
abstract: As we have shown previously the nucleus of sympathetic neurons contains microtubules and microfilaments giving rise to highly organized inclusions. Present in vivo experiments on cat stellate ganglia have shown that dibutyryl cyclic AMP and theophyllin induce an increase of their frequency (up to 8.5 fold). These and earlier observations lead us to conclude that cyclic AMP mediates the process of nuclear microtubules and microfilaments assembly from preformed protein subunits.
