The invention provides methods of screening for substances having an effect on a nicotine receptor by contacting a cell having a nicotine receptor with a test substance; and determining any increase or decrease in phosphorylation of Janus-Activated Kinase 2 (JAK2). An increase in phosphorylation of JAK2 indicates that the test substance stimulates the nicotine receptor, and wherein a decrease in phosphorylation of JAK2 indicates that the test substance inhibits the nicotine receptor. The invention also provides screening methods for identification of substances that affect nicotine receptor activity through activity mediated by the AT2 receptor. Related pharmaceutical compositions and methods of treatment are also provided.
本发明提供了筛选对尼古丁受体有影响的物质的方法,方法是将具有尼古丁受体的细胞与测试物质接触;并确定Janus-Activated Kinase 2(JAK2)磷酸化的增加或减少。JAK2 磷酸化的增加表明受试物质刺激了尼古丁受体,而 JAK2 磷酸化的减少表明受试物质抑制了尼古丁受体。本发明还提供了筛选方法,用于鉴定通过 AT2 受体介导的活性影响尼古丁受体活性的物质。本发明还提供了相关的药物组合物和治疗方法。
