应用案例：多器官芯片用于结核病疫苗和候选药物的测试

德国TissUse公司获得比尔和梅琳达·盖茨基金会的资助，在HUMIMIC芯片上开发人类临床前肺-肝-淋巴结串联共培养物，用于研究感染结核分枝杆菌的结核病疫苗开发和候选药物的测试。这一合作将有助于开发结核病候选疫苗和治疗模式。

德国TissUse公司今天宣布，它已经从比尔和梅琳达·盖茨基金会获得了一个为期3年的项目的资金。联合研究活动的目标是开发一种血管化的微生理系统，将人肺、肝和淋巴结类器官串联起来，用于筛选结核疫苗候选药物和治疗模式。

“我们很高兴在这一项目中与结核疫苗行动(TBVI)作为协调员和国家科学研究中心(CNRS)作为科学伙伴进行合作。- Uwe Marx教授，TissUse CSO。

微生理模型将支持组织稳态，并将在数周内对治疗效果进行监测。空气传播感染结核分枝杆菌后，新模型系统旨在展示结核分枝杆菌"吞噬受阻"、气血屏障破坏、淋巴结组织活化及肉芽肿形成和维持等疾病特异性表型。然后，该疾病模型将用于测试结核病候选疫苗的筛查。 

“我们很高兴能够借助这一项目为开发结核病新疫苗和未来治疗方法作出贡献，并感谢比尔和梅琳达·盖茨基金会支持我们的愿景并资助这一项目。- Reyk Horland博士，TissUse的首席执行官。

TissUse will receive funding from the Bill & Melinda Gates Foundation to develop a human preclinical lung-liver-lymph node co-culture on a HUMIMIC Chip infectable with Mycobacterium tuberculosis. This collaboration will contribute to the development of Tuberculosis vaccine candidates and treatment modalities.

TissUse announced today that it has received funding from the Bill & Melinda Gates Foundation for a 3-year project. The joint research activities have the goal to develop a vascularized microphysiological system interconnecting human lung, liver and lymph node organoids capable of screening Tuberculosis vaccine candidates and treatment modalities.

“We are pleased to collaborate in this project with the TuBerculosis Vaccine Initiative (TBVI) as a coordinator and the Centre National de Recherche Scientifique (CNRS) as a scientific partner.” – Prof. Dr. Uwe Marx, CSO of TissUse.

The microphysiological model will support tissue homeostasis and will be monitorable for treatment efficacy over weeks. After airborne infection with Mycobacterium Tuberculosis, the new model system aims to show the disease-specific phenotype of “frustrated” phagocytosis, air-blood barrier damage, activated lymph node tissue and granuloma formation and maintenance. The disease model will then be used to test screening of TB vaccine candidates.

“We are excited to be able to contribute with this project to the development of new vaccines and future treatments for Tuberculosis and would like to thank the Bill & Melinda Gates Foundation for supporting our vision and funding this project.” – Dr. Reyk Horland, CEO of TissUse.
