Adenosine-3',5'-monophosphate in salivary glands of unfed and feeding female lone star ticks, Amblyomma americanum (L.).
Basal levels of cAMP in salivary glands of female lone star ticks were found to be about 5 pmoles/mg protein during all stages of feeding. Glands stimulated with 10(-5)M dopamine and 10(-5)M dopamine plus theophylline exhibited significant increases in cAMP/mg protein. After stimulation by 10(-5)M dopamine was removed, cAMP decreased faster in glands from slowly feeding ticks (less than 200 mg) than in glands of rapidly feeding ticks (greater than 200 mg).
