Review outlines key cellular signalling pathways affecting neuroinflammation and cell survival in neurodegenerative diseases, suggesting new therapeutic interventions.
Neurodegenerative diseases (NDs), including Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD), and Parkinson's disease (PD), are characterised by impaired cellular homeostasis and progressive neuronal loss. Emerging evidence highlights the critical role of cellular signalling pathways in the progression and pathogenesis of these disorders. With a focus on the NLRP3 inflammasome, Wnt/β‐catenin, and Hippo‐YAP cascades, this review focuses on new signalling pathways linked to neurodegenerative disorders. Among them, the NLRP3 inflammasome is a crucial mediator of neuroinflammation, causing neuronal damage and persistent immune activation. In contrast, these pathways regulate neurogenesis, synaptic plasticity, and cell survival, offering potential neuroprotective functions. Dysregulation of these pathways disrupts cellular integrity, exacerbates disease progression, and represents a convergence point for therapeutic intervention. In NDs, knowing how these pathways interact offers fresh perspectives on disease processes and finds new targets for the creation of disease‐modifying treatments.
