Chagasic IgG modifies the activity of sarcolemmal ATPases through a β adrenergic mechanism

The effect of anti β adrenoceptor IgG from chagasic sera upon Ca2+-ATPase and Na++K+-ATPase of myocardial membrane was studied. Chagasic IgG stimulated Ca2+-ATPase and inhibited Na++K+-ATPase activities. Both enzymatic effects of the IgG could be prevented after β adrenoceptor blockade or after the...
