視覺神經(jīng)科學(xué)

在神經(jīng)科學(xué)的范圍內(nèi)，視覺神經(jīng)科學(xué)已經(jīng)成為第一個涵蓋從分子和細(xì)胞過程到高級生理學(xué)和視覺心理物理學(xué)的所有實驗方面的真正的跨學(xué)科工作之一。在過去的半個世紀(jì)中對脊椎動物和無脊椎動物視覺系統(tǒng)的實驗為統(tǒng)計信息和賦予精美特征的神經(jīng)系統(tǒng)的設(shè)計和功能提供了一個通用框架。盡管加州大學(xué)洛杉磯分校在視覺科學(xué)的每個實驗方面都有優(yōu)勢，但直到去年，視覺神經(jīng)科學(xué)從未被用作將視覺科學(xué)家聚集在一起的組織結(jié)構(gòu)。視覺神經(jīng)科學(xué)親和小組的使命是為參與者提供一個論壇，以便在生物學(xué)和心理學(xué)的各個層面進(jìn)行互動，程序：這個親密團(tuán)體在十月至六月間每月開會。該計劃將重點(diǎn)介紹親和力小組成員實驗室所產(chǎn)生的科學(xué)數(shù)據(jù)。將特別強(qiáng)調(diào)高級研究生或博士后研究人員，為他們提供正式的指導(dǎo)和反饋。親和團(tuán)每季度一次，將邀請來自大學(xué)以外的知名演講者參加開放的研討會，并與學(xué)員進(jìn)行交流。

癌癥研究領(lǐng)域

在文獻(xiàn)中存在2個月至11.5個月的等基因Atm缺陷小鼠壽命中巨大的不明原因的實驗室間和實驗室間差異。腸道微生物群在我們的健康中起著關(guān)鍵的作用; 部分原因是這些細(xì)菌比我們體內(nèi)的人體細(xì)胞多10倍，因為它們具有巨大的代表謝能力。身體特別是免疫系統(tǒng)與腸道微生物之間錯綜復(fù)雜的相互作用強(qiáng)烈地明腸道微生物群影響全身穩(wěn)態(tài)。腸道微生物群組成的差異與諸如肥胖癥，糖尿病和行為的疾病有關(guān)。然而，正常的非致病性腸道細(xì)菌在致癌作用中的作用目前尚不清楚。

目前的研究項目

Robert Schiestl博士實驗室對Atm缺陷小鼠的腸道細(xì)菌性質(zhì)顯著影響遺傳不穩(wěn)定性，壽命和淋巴瘤潛伏期進(jìn)行了觀察。ATM在DNA雙鏈斷裂修復(fù)，檢查點(diǎn)控制和氧化還原平衡中非常重要。Atm - / - 小鼠模擬人類疾病共濟(jì)失調(diào)毛細(xì)血管擴(kuò)張癥（AT），其特征是喪失運(yùn)動技能，免疫系統(tǒng)受損，癌癥風(fēng)險增加和過早。AT無法治愈。他們將小鼠保持在無菌環(huán)境中，另外通過實驗改變這種微生物群來特別測試腸道微生物群的貢獻(xiàn)。他們明，同基因Atm - / - 小鼠在10％和43％之間的雙基因座處有DNA缺失的顯著變化，此外，Schiestl實驗室從健康有益的微生物群中分離出一種細(xì)菌 - 約氏乳桿菌，其自身顯著降低了基因毒性，減少了炎性細(xì)胞因子，誘導(dǎo)了抗炎細(xì)胞因子，并降低了自然殺傷細(xì)胞，細(xì)胞毒性T細(xì)胞和CD3細(xì)胞的流行肝臟和外周血，這些都與炎癥有關(guān)。另外，他們在野生型小鼠中發(fā)現(xiàn)了P53缺陷型小鼠的類似差異，甚至更少。因此，這種影響是非常重要的。他們的發(fā)現(xiàn)提出了一個直到現(xiàn)在未征的實驗變量，這可能具有巨大的影響。首先在AT患者中預(yù)防或延緩淋巴瘤，其次為基礎(chǔ)研究，其中Atm和許多其他癌癥傾向性小鼠模型的眾多實驗室間和實驗室間的差異部分或全部由腸道微生物群的差異來解釋。另外，我們的AT小鼠模型對腸炎癥過敏。由于炎癥與諸如心臟病，所有癌癥，神經(jīng)退行性疾病，關(guān)節(jié)炎，哮喘，糖尿病，可燃腸道疾病，克羅恩氏病等的許多疾病有關(guān)，所以在該動物模型中鑒定的細(xì)菌可以作為益生菌受益，所有這些疾病。

Dr.Elaine Y.Hsiao is an Assistant Professor in the Department of Integrative Biology & Physiology at UCLA, where she leads a laboratory studying fundamental interactions between the microbiome, brain and behavior, and their applications to neurological disorders.Her studies on the relationships between the microbiota, immune system and nervous system led her to discover that the microbiota can regulate behavioral, metabolic and gastrointestinal abnormalities relevant to autism spectrum disorder (ASD).Her work in this area, and on neuroimmune interactions in autism, has led to several honors, including the National Institutes of Health Director’s Early Independence Award, distinction as Forbes’ 30 Under 30 in Science and Healthcare, National Geographic’s Emerging Explorer Award and fellowships from the National Institute of Mental Health and Autism Speaks.Inspired by this interplay between the microbiota and nervous system, the Hsiao laboratory is mining the human microbiota for microbial modulators of host neuroactive molecules, investigating the impact of microbiota-immune system interactions on neurodevelopment and examining the microbiome as an interface between gene-environment interactions in neurological diseases.
