摘要: In this review, Joel Linden summarizes what is known about a new and intriguing member of the adenosine receptor family, A3 receptor. This exhibits unusually large differences in structure, tissue distribution pharmacological properties between species. Rat receptors are resistant to blockade by xanthine antagonists, but human sheep can be potently blocked certain xanthines, notably acidic 8-phenylxanthines. One function facilitate degranulation mast cells, role for cells mediating myocardial preconditioning has been proposed. Therefore, selective antagonists have potential treatment allergic, inflammatory possibly ischaemic disorders.
