AutograFt Immune CompeteNt HumAn GLioblastoma ModEl (FINALE)
Glioblastoma (GBM) is the most aggressive form of brain tumor with a median patient survival time of less than 14 months. The tumor microenvironent (TME) within GBM is a key regulator of tumor proliferation and drug-resistance and thus has entered the spotlight as a potential therapeutic target. Progress towards the development of treatments targeting the TME is currently limited due to a lack of reliable preclinical model that can accurately recreate the distinct features of the human brain. To this end, I recently established a human cortical tissue based GBM model which is identical to the human brain with respect to composition and function. My long term goal is to understand the molecular details of GBM’s distinctive physiology, and to apply this knowledge in the development of novel therapeutic strategies. The central hypothesis based on previously published data is that there exists unwanted immune responses and interactions within the TME in the existing patient-mismatched model, with respect to tumor growth and interactions. Hence, the objective of the proposed project “FINALE” is to establish personalized GBM models which can address this paucity in a comprehensive and physiologically relevant fashion. We will pursue this project using an innovativecombination of tissue engineering and transcriptomic characterization using state of the art techniques, as we have demonstrated previously. This work would be a stepping stone towards engineering human brain models that can precisely dissect mechanisms of GBM progression, accelerate clinical testing and, most importantly, provide a platform for personalized medicine.
