Neurodegenerative diseases such as Alzheimer's, Parkinson's, frontotemporal dementia, and ALS are characterized by amyloid protein aggregation involving intrinsically disordered proteins that are also capable of liquid-liquid phase separation (LLPS). LLPS, known to drive the formation of dynamic membraneless organelles essential for cellular functions, can play a role in limiting fibrillation process or aberrantly transition into solid aggregates under pathological conditions. Here we review how mutations, post-translational modifications, and environmental factors can modulate LLPS of proteins like Tau, TDP-43, FUS, and α-synuclein, potentially regulating amyloid aggregation. We also examine the interplay of these proteins exploring how LLPS and condensate maturation could impinge on the emergence of co-pathologies contributing to disease progression. Finally we discuss emerging therapeutic strategies, aimed at modulating phase separation dynamics.
