Supports distinct Ca handling by noradrenaline versus caffeine in arteries; extends mechanistic insights but leaves open human translation.
Noradrenaline and caffeine induce contractions in rabbit mesenteric arteries through different mechanisms of calcium handling, with NA requiring intact cell membranes and promoting calcium re-accumulation.
Itoh et al. (1983) studied this question.
