Tau 蛋白-阿爾茨海默癥(AD)治療新天地
一個(gè)很多人在晚年躲不開的大麻煩, 就是我們早已不陌生的那個(gè)名字,阿爾茨海默癥(Alzhemier Disease),也叫AD。
AD(Alzhemier Disease) , 是德國醫(yī)生阿爾茨海默最先發(fā)現(xiàn)的一種腦神經(jīng)疾病。它的主要癥狀有兩個(gè):一是 β-淀粉樣蛋白在神經(jīng)元細(xì)胞外異常沉積形成的老年斑;二是 tau 蛋白的異常磷酸化所形成的 NFTs(神經(jīng)元纖維纏結(jié))。 但是,很多在大腦中出現(xiàn)淀粉樣蛋白沉積的老年人并沒有失智癥狀。而與AD相關(guān)的記憶喪失和頭腦混亂的癥狀與tau蛋白纏結(jié)相關(guān)。因此,近年來已有多種療法試圖靶向tau蛋白的產(chǎn)生和清除過程來治療AD。
Tau蛋白粉墨登場 日前在《Neuron》科學(xué)期刊上發(fā)表的最新研究表明,tau蛋白在神經(jīng)細(xì)胞中的生成和分泌過程是一個(gè)主動(dòng)的,受到調(diào)節(jié)的過程。這項(xiàng)發(fā)現(xiàn)可能幫助開發(fā)出基于靶向tau蛋白生成過程的AD療法。
AD 患者腦中存在大量異常 Tau 蛋白。Tau 蛋白異常修飾、含量變化對臨床 AD 病理發(fā)生有重要作用。Tau 蛋白異常磷酸化和異常糖基化相互作用促進(jìn) PHF/NFT 結(jié)構(gòu)最終形成。
AD研究最新方向 AD 患者腦組織切片上的沉淀斑塊和神經(jīng)元纖維纏結(jié)是 AD 的主要病理特征。因此,沉淀斑塊的主要組成 β-淀粉樣蛋白以及纖維纏結(jié)的主要成分 tau 蛋白是目前 AD 研究的最主要方向。
由于采用 Aβ 通路作為靶點(diǎn)治療輕至中度 AD 的臨床試驗(yàn)相繼以失敗告終,tau 靶向藥物,特別是 tau 聚集抑制劑對 AD 潛在的治療作用越來越引人關(guān)注。以 Tau 通路作為靶點(diǎn)的治療策略主要著重于限制引起 tau 蛋白早期聚集的病理性磷酸化。
一個(gè)Tau蛋白,開啟一段醫(yī)療傳奇 ——基于 Tau 通路的幾種藥物開發(fā)策略:
1. 通過 tau 穩(wěn)定劑增強(qiáng)微管的穩(wěn)定化 TPI.287 | UCSF | Microtubule stabilizer | Stage I (ongoing) | NCT01966666 |

3. 采用主動(dòng)免疫療法提高磷酸化 tau 蛋白的清除水平 AADvac.1 | Axon Neuroscience SE | Active vaccine, tau 294-305 | Stage II (ongoing) | NCT02579252 | ACI35 | AC Immune/ Janssen | Active vaccine,16 copies of a tau fragment phosphorylated at S396/S404 (PHF1) | Stage Ib (completed) | ISRCTN13033912 |
4. 對參與 Tau 蛋白轉(zhuǎn)錄后修飾的蛋白進(jìn)行調(diào)控,阻止 Tau 蛋白的過度磷酸化 Saracatinib (AZD0530) | AstraZeneca | Src/Abl抑制劑, Fyn信號(hào)通路 | Stage II (ongoing) | NCT02167256 | ANAVEX 273 | Anavex | σ1/muscarinic ligand | Stage II (recruiting) | NCT02756858 |
