A Flow-assay for Farnesol Removal from Adherent Candida albicans Cultures

[Abstract]  Here, we describe a protocol for a continuous flow system for C. albicans cultures growing adherent to a plastic surface. The protocol was adapted from a previous method established to simulate blood flow on endothelial cells (Wilson and Hube, 2010). The adapted protocol was used by us for the removal of molecules in C. albicans supernatants, especially farnesol, which accumulate over the time course of incubation and cannot be specifically depleted. The system used, however, allows various applications including the simulation of physiological flow conditions. Several ... [摘要]  在这里,我们描述了用于连续流系统的协议。 白色念珠菌生长粘附在塑料表面上的培养物。 该方案根据建立以模拟内皮细胞上的血液流动的先前方法改编(Wilson和Hube,2010)。 我们使用适应方案去除C中的分子。 白色念珠菌上清液,特别是法呢醇,其在孵育的时间过程中积累并且不能被特异性地耗尽。 然而,所使用的系统允许各种应用,包括模拟生理流动条件。 制造商网站上给出了几个示例应用程序(https://ibidi.com/perfusion-system/112-ibidi-pump-system.html).
【背景】法尼醇是人类致病真菌白色念珠菌中的酵母 - 菌丝转移(Hornby等人,2001)的有效抑制剂,并且还促进了酵母生长的逆转预制长丝(Lindsay等人,2012)。群体感知分子(QSM)快速积聚在白念珠菌EED1缺失株的上清液中,并促进突变体(Polke等人)的反向形态发生和菌丝维持缺陷>,2017)。由于我们无法阻止法呢醇的合成(Polke等人,2017),我们使用了ibidi ®泵系统,通过单向去除上清液中累积的QSMs流。流动应用以及在孵育期间的恒定的培养基更换在C中显着延长了丝状化。白色念珠菌eed1Δ突变体。这表明QSM积累的成功去除,并且提供了在C中的菌丝维持和法呢醇信号之间的直接联系。白色假丝酵母。用于此协议(ibidi ...

A Co-culture Assay to Determine Efficacy of TNF-α Suppression by Biomechanically Induced Human Bone Marrow Mesenchymal Stem Cells

[Abstract]  The beneficial effects of mesenchymal stem cell (MSC)-based cellular therapies are believed to be mediated primarily by the ability of MSCs to suppress inflammation associated with chronic or acute injury, infection, autoimmunity, and graft-versus-host disease. To specifically address the effects of frictional force caused by blood flow, or wall shear stress (WSS), on human MSC immunomodulatory function, we have utilized microfluidics to model WSS at the luminal wall of arteries. Anti-inflammatory potency of MSCs was subsequently quantified via measurement of TNF-α production by activated ... [摘要]  认为基于间充质干细胞(MSC)的细胞疗法的有益作用主要是由能够抑制慢性或急性损伤,感染,自身免疫和移植物抗宿主病相关炎症的能力介导的。 为了专门解决由血流或壁剪应力(WSS)引起的摩擦力对人MSC免疫调节功能的影响,我们利用微流体在动脉腔壁上建模WSS。 随后通过在共培养测定中通过活化的小鼠脾细胞测量TNF-α产生来量化MSC的抗炎效力。 TNF-α抑制测定作为MSC效力的功能评估的可重现平台,并且表现出作为MSC治疗功效的替代测定的预测价值。
【背景】间充质干细胞(MSC)的免疫调节活性由直接细胞相互作用和旁分泌因子介导(Singer和Caplan,2011;英语,2013)。 MSCs被认为是源于与骨髓和各种组织内脉管系统内皮细胞相关的周细胞(Sacchetti et al。,2007; Crisan et al。,2008)。这种独特的血管周围位置将它们置于血流中的炎症和其他可溶性因子附近,使其监测系统信号。事实上,将壁壁细胞募集到内皮是血管成熟的关键事件,周细胞在血管维持和完整性中起关键作用(Benjamin et al。,1998; ...

[Abstract]  This method allows evaluating the relative adhesion strength between T lymphocytes and specific adherent target cells using a shear force in flow chambers. It is based on the measure of the resistance of conjugates formed between T cells and adherent tumor cells to shear stress in a microfluidic system. For this purpose, T cells, stained with a CellTracker probe, are added into flow channels containing a monolayer of adherent target cells and their progressive detachment under a constant shear stress is then recorded using a fluorescent microscope. [摘要]  该方法允许使用流动室中的剪切力评估T淋巴细胞和特异性粘附靶细胞之间的相对粘附强度。 其基于在微流体系统中T细胞和粘附的肿瘤细胞之间形成的缀合物对剪切应力的抗性的测量。 为此,将用CellTracker探针染色的T细胞加入含有单层粘附靶细胞的流动通道中,然后使用荧光显微镜记录在恒定剪切应力下的其逐渐分离。
