題目Rational design and optimization of downstream processes of virus particles for biopharmaceutical applications: Current advances 摘要 The advent of advanced therapies in the pharmaceutical industry has moved the spotlight into virus-like particles and viral vectors produced in cell culture holding great promise in a myriad of clinical targets,including cancer prophylaxis and treatment. Even though a couple of cases have reached the clinic, these products have yet to overcome a number of biological and technological challenges before broad utilization. Concerning the manufacturing processes, there is significant research focusing on the optimization of current cell culture systems and, more recently, on developing scalable downstream processes to generate materialfor pre-clinical and clinical trials. We review the current options for downstream processing of these complex biopharmaceuticals and underline current advances on knowledge-based toolboxes proposed for rational optimization of their processing. Rational tools developed to increase the yet scarce knowledge on the purification processes of complex biologicals are discussed as alternative to empirical, “black-boxed” based strategies classically used for process development. Innovative methodologies based on surface plasmon resonance, dynamic light scattering, scale-down high-throughput screening and mathematical modeling for supporting ion-exchange chromatography show great potential for a more efficient and cost-effective process design, optimization and equipment prototyping. 求高人指點一下這篇文章大概說什么的 什么個意思 我是真心看不懂 我不是學(xué)生物的 題目什么意思也行 謝謝各位啦 [ Last edited by 青春風(fēng)鈴 on 2013-11-12 at 15:50 ] |

| 摘要 :生物醫(yī)藥行業(yè)中先進(jìn)療法的出現(xiàn)聚焦于細(xì)胞培養(yǎng)中病毒樣粒子和病毒載體的生產(chǎn)給多樣化的臨床目標(biāo),包括癌癥的預(yù)防和治療帶來了很大的希望。即使有些研究項目已經(jīng)達(dá)到臨床階段,這些產(chǎn)品在廣泛應(yīng)用之前還沒有克服一系列生物技術(shù)的挑戰(zhàn)。考慮到制造行業(yè)的工藝流程,有一項有重大意義的研究集中于目前細(xì)胞培養(yǎng)系統(tǒng)優(yōu)化,最近關(guān)于發(fā)展為臨床前和臨床試驗生產(chǎn)物質(zhì)的大規(guī)模下游工藝。我們回顧這些復(fù)雜生物制藥下游工藝的選擇,強調(diào)目前的優(yōu)勢是基于知識工具箱的提議為了合理優(yōu)化他們的工藝。合理工具的發(fā)展使得復(fù)雜生物純化過程知識的不足作為供替代的選擇已經(jīng)被討論。基于“黑盒子”戰(zhàn)略擬古地用于工藝發(fā)展;诒砻娴入x子共振,動態(tài)光散射,模擬高通量篩選和支持離子交換色譜法的數(shù)學(xué)建模的先進(jìn)的方法論在高效、成本效益好的工藝設(shè)計合理化及設(shè)備原型方面都顯現(xiàn)出很大的潛力。 |
