Adenosine-induced apoptosis in chick embryonic sympathetic neurons: a new physiological role for adenosine.


1. A newly found action of adenosine in neurons, which may have an important physiological function in the growth and development of the sympathetic nervous system, is described. Adenosine (1-100 microM) inhibited neurite outgrowth within the first 24 h and killed about 80% of sympathetic neurons supported by nerve growth factor over the next 2 days in… (More)
