　　細(xì)胞內(nèi)的蛋白質(zhì)和RNA合成后要被運(yùn)輸?shù)讲煌膮^(qū)域發(fā)揮作用，神經(jīng)元是一種特化的細(xì)胞，除了胞體它還具有長(zhǎng)的軸突和樹突，因此蛋白質(zhì)和RNA在細(xì)胞內(nèi)的長(zhǎng)距離運(yùn)輸就更為重要。我們近期的研究對(duì)兩部分的研究?jī)?nèi)容感興趣，一方面是細(xì)胞內(nèi)運(yùn)輸?shù)能壍牢⒐苁芪⒐艿鞍酌艽a(翻譯后修飾和亞型)的調(diào)控及對(duì)神經(jīng)元發(fā)育和神經(jīng)系統(tǒng)疾病的影響，另一方面是神經(jīng)元中非編碼RNA的運(yùn)輸和調(diào)控機(jī)制以及在感覺傳遞和神經(jīng)元發(fā)育中的生理意義。

　　微管是細(xì)胞內(nèi)物質(zhì)轉(zhuǎn)運(yùn)的軌道，使得生長(zhǎng)必須的蛋白質(zhì)、RNA以及膜結(jié)構(gòu)源源不斷的往末梢運(yùn)輸，從而幫助神經(jīng)元軸突快速的生長(zhǎng)。在神經(jīng)元發(fā)育過程中，微管蛋白及微管結(jié)構(gòu)會(huì)不斷受到細(xì)胞內(nèi)分子和外界信號(hào)的調(diào)控，影響微管的聚合或解聚。微管功能調(diào)控在神經(jīng)元極性形成和軸突生長(zhǎng)的過程中起著至關(guān)重要的作用。我們將圍繞微管蛋白密碼，鑒定微管蛋白翻譯后修飾和微管蛋白亞型對(duì)微管功能的調(diào)控作用，并揭示其在神經(jīng)元內(nèi)物質(zhì)運(yùn)輸、神經(jīng)系統(tǒng)發(fā)育(神經(jīng)元生長(zhǎng)、極性形成和遷移)和神經(jīng)系統(tǒng)疾病中的重要作用。

　　非編碼RNA主要包括微小RNA (miRNA)和長(zhǎng)鏈非編碼RNA(lncRNA)等，它們具有高度的組織特異性，并通過多種機(jī)制發(fā)揮調(diào)控作用。在初級(jí)感覺神經(jīng)元發(fā)育和感覺信息傳遞中，非編碼RNA的運(yùn)輸和定位受到外界信號(hào)以及RNA結(jié)合蛋白等分子的精確調(diào)控。我們通過鑒定神經(jīng)元軸突特異分布的miRNA和lncRNA以及細(xì)胞類型特異定位的lncRNA，揭示軸突富集非編碼RNA以及細(xì)胞類型特異性的lncRNA在神經(jīng)元軸突發(fā)育以及感覺信息傳遞中的功能和作用機(jī)制。
