研究雌激素受体(ER)敲除小鼠脑内,ERa和ERβ在介导内侧杏仁核中白细胞介素1β(IL-1β)表达的作用。IL-1β表达有显著的性别差异,并且在ER敲除小鼠含量减少。细菌脂多糖(LPS)或卵巢切除能够促进野生型和ERβ敲除小鼠(BERKO)IL-1β表达,但对ERa敲除小鼠(ERKO)无作用。相似的是.外源性雌激素能抑制野生型和BERKO小鼠IL-1β表达,后者时间稍有延搁,但对ERKO IL-1β表达没有影响。结果表明,ERα是内侧杏仁核IL1β表达调节的重要机制,提示ERs可作为选择性靶基因治疗和预防神经功能失常。
研究雌激素受體(ER)敲除小鼠腦內,ERa和ERβ在介導內側杏仁覈中白細胞介素1β(IL-1β)錶達的作用。IL-1β錶達有顯著的性彆差異,併且在ER敲除小鼠含量減少。細菌脂多糖(LPS)或卵巢切除能夠促進野生型和ERβ敲除小鼠(BERKO)IL-1β錶達,但對ERa敲除小鼠(ERKO)無作用。相似的是.外源性雌激素能抑製野生型和BERKO小鼠IL-1β錶達,後者時間稍有延擱,但對ERKO IL-1β錶達沒有影響。結果錶明,ERα是內側杏仁覈IL1β錶達調節的重要機製,提示ERs可作為選擇性靶基因治療和預防神經功能失常。

IL- 1β expression in the medial amygdaloid nucleus (McA) from ERs (estrogen receptors) knockout mice was carried out to determine the roles of ERα and ER β in mediating IL-1β expression in the brain. There was clear sex difference of 1L-1β expression in MeA and 1L-1β expression was reduced in ERs-knockout mice. Either LPS or ovariectomy could enhance IL-1β expression in both wild type (WT) and ERβ knockout mice (BERKO), but not in ERa knockout mice (ERKO). Similarly, exoge nous estrogen could inhibit I1-1β expression in McA both from WT and BERKO mice, with the later in a lagged manner, but not from ERKO. The results clearly establish that ERa is a critical mechanism for IL-1β expression in McA, implying for a selective targeting of ERs in the treatment and prevention of neural dysfunction.
