Molecular profiling has identified 3 groups of meningiomas, with MenG C tumors exhibiting the vast majority of recurrences. Efforts to find effective treatments for recurrent meningiomas have remained elusive. Higher WHO-grade meningiomas have exhibited greater Programmed Death Ligand 1 (PD-L1) expression through various methods, but the prognostic value of PD-L1 expression has not been described in the context of molecular profiling. Additionally, trials investigating PD-1/PD-L1-targeted immunotherapies have produced disappointing results. Here, we find that PD-L1 positivity, while prevalent in MenG C tumors, does not predict recurrence in the benign MenG A and B tumors. PD-L1 positivity also occurs independently of …

Tubulin Transforms Tau And Α-Synuclein Condensates From Pathological To Physiological, Lathan Lucas, Phoebe S Tsoi, My Diem Quan, Kyoung-Jae Choi, Josephine C Ferreon, Allan Chris M Ferreon

Faculty, Staff and Students Publications

Proteins undergo phase separation to form membraneless condensates that spatially organize biomolecular interactions. These condensates can support cellular physiology or instigate pathological protein aggregation. Tau and α-synuclein (αSyn) are neuronal proteins that form heterotypic Tau:αSyn condensates associated with physiological and pathological processes. Tau and αSyn regulate microtubules, but also misfold and co-deposit in aggregates linked to neurodegenerative disease, highlighting the ambivalent impact of Tau:αSyn condensation in health and disease. Here, we show that Tubulin modulates Tau:αSyn condensates by promoting microtubule interactions and inhibiting homotypic and heterotypic pathological oligomers. In the absence of Tubulin, Tau-driven condensation accelerates formation of pathogenic Tau:αSyn …
