具体要求:
肾近端小管是肾单位的一部分(肾脏的功能部件),是人体高专属性参与重吸收和排泄各种物质(包括盐和矿物质)的器官,盐和矿物质的重吸收对身体是非常重要的,否则会失去在尿液中。此外,肾近端小管对许多药物的处理也是至关重要的,所谓的外源性物质,来自外面的身体和环境(如许多人造物质,包括潜在的毒素)。然而,没有好的体外模型可以描述和模仿肾近端小管的功能。建立肾近端小管一个有力的模型是非常必要的,特别是在肾近端小管在药物的相互影响方面有至关重要的作用,因为它是会由于药物毒性和药物之间的作用而非常容易受到伤害导致肾脏疾病。在体外开发肾近端小管模型的系统可以帮助填补肾脏疾病研究中药物毒性和药物处理方面的一些空白。

The proximal tubule, a part of the kidney nephron (the functional unit of the kidney), has highly specialized properties to do with the salvage and excretion of various compounds, salts and minerals that are very important to the body and would otherwise be lost in the urine. In addition, the proximal tubule is essential for the handling of many drugs and so-called xenobiotics that come from outside the body and from the environment (e.g., many artificial substances, including potential toxins). However, there are no good human models in vitro that can recapitulate and reproduce the function of the proximal tubule.   A robust model for the proximal tubule is needed, especially since the proximal tubule has an essential role in drug clearance, because it is highly susceptible to damage in many kidney diseases, and it is also a target for drug-drug interactions and drug toxicity. Development of a proximal tubule model system in vitro could help to address some of the gaps in laboratory models for the study of kidney disease, toxicity, and drug handling. 

AstraZeneca is seeking innovative approaches to developing a model system of the proximal tubule in vitro. Ideally, the model should incorporate a self-contained microphysiological unit in which biologically appropriate media, fluid flow, and shear stress can be modulated to reproduce the properties of the proximal tubule in vivo and ultimately recapitulate the structural and cellular conditions necessary for integrated proximal tubular function. 

This is an ideation challenge and only requires a written solution.

  Challenge Overview
Currently, there are no good human in vitro models that reflect the function of the intact mammalian proximal tubule, which reabsorbs filtered sodium and water, but also has specific mechanisms for reabsorption of glucose, low molecular weight proteins, amino acids, urate and phosphate, as well as the handling of weak acids and bases, and xenobiotics, including many drugs. The proximal tubule can be severely affected in kidney injury and disease, and is also a target for drug-drug interactions and drug toxicity. Development of a proximal tubule model system, as opposed to another ‘simple’ cell culture monolayer, could address some of the gaps in suitable models in vitro for studying kidney disease, drug toxicity, and DMPK. 

AstraZeneca is seeking innovative approaches to developing a model system of the proximal tubule in vitro. Ideally, the model should incorporate a self-contained microphysiological unit in which biologically appropriate media, fluid flow, and shear stress can be modulated to reproduce the properties of the proximal tubule in vivo and ultimately recapitulate the structural and cellular conditions necessary for integrated proximal tubular function. 

ABOUT THE SEEKER

AstraZeneca is a global, research-based, biopharmaceutical company with a focus on five key therapeutic areas: 1) cardiovascular & metabolic diseases, 2) oncology, 3) respiratory, inflammation & autoimmunity, 4) neuroscience, and 5) infection. As an innovation-driven, research organization, AstraZeneca recognizes that great ideas come from many sources. Open innovation is an avenue by which ideas can be shared and AstraZeneca recently launched a pavilion to further its commitment to facilitate the advancement of pharmaceutical research.
