LPS initiates cells through TLR4,which binds to MyD88, then IRAK binds with the complex and activates TRAF6.The ubiquitination of TRAF6 is needed during the process,then TAKl,a member of MAP3K,is activated by ubiquitinated TRAF6 and phospherylates IKK β.

分叶征和深分叶征的汇总敏感性分别为0.78、0.50，汇总特异性分别为0.82、0.94，汇总阳性拟然比分别为3.42、6.22，汇总阴性拟然比分别为0.31、0.56，汇总的诊断比值比分别为14.2、13.1。

Immunohistochemical localization of inhibin α-subunit in normal mature rats was carried out by using Strept Avidin-Biotin-Peroxidase Complex .The results showed that there was positive immunoreactivity of the McAb to inhibinα-subunit in heart ,kidney , spleen , lymph ,adrenal gland and pancreas cells. It indicated that inhibinα-subunit existed in the above tissues , But no positive sites were seen in hypothalamus, pituitary, lung and liver, that means they have no inhibinα-subunit. Compared with the ovariectomized rats, the hypothalamus and pituitary of the rats injected with inhibin-α fragment（1～32）showed an positive reaction, suggesting that inhibin α-subunit could pass through the blood-brain barrier .

用链霉亲和素-生物素-过氧化物酶(Strept Avidin-Biotin-Peroxidase Complex， SABC)免疫组织化学方法，以抑制素α亚基单克隆抗体对正常雌性性成熟大鼠各组织的抑制素α亚基进行定位观察，结果显示：⑴大鼠心脏、肾、脾、淋巴、肾上腺、胰腺均呈阳性反应，表明存在抑制素α亚基；下丘脑、垂体、肝脏和肺组织呈阴性反应，表明其不存在抑制素α亚基；⑵与去卵巢大鼠相比，外源注射抑制素α（1～32）片段的大鼠其下丘脑和垂体出现阳性反应，说明抑制素α亚基能通过血脑屏障。
