Clinicians face an urgent need to shift from symptomatic management toward modifying the very pathways that drive neurodegenerative diseases, yet pinpointing actionable targets in disorders like Alzheimer’s and Parkinson’s remains elusive.
Emerging research identifies the protein C/EBPβ as a regulator of reactive gliosis, a critical process in Alzheimer’s pathology, presenting a potential lever to alter disease progression. This protein as a treatment target highlights a potential shift in therapeutic strategies: instead of solely focusing on neuronal replacement or neurotransmitter modulation, therapies could directly modulate glial activation and the cascade of neuroinflammation.
Reactive gliosis, characterized by the proliferation and hypertrophy of astrocytes and microglia, underpins inflammatory cascades that exacerbate neuronal dysfunction and synaptic loss. Addressing this aspect of neuroinflammation may slow atrophy in vulnerable brain regions and complement existing strategies aimed at cognitive preservation.
Tau protein aggregation remains a hallmark of Alzheimer’s disease, correlating with synaptic degeneration and worsening cognitive decline. Interventions that disrupt tau pathology could therefore translate into meaningful clinical benefits, offering a second mechanistic pillar alongside gliosis control for comprehensive neuroprotection, as evidenced by recent tau-targeting therapies.
Sleep disturbances have emerged as both a symptom and a driver of neurodegeneration, amplifying tau buildup during impaired restorative cycles. In this context, lemborexant, an orexin receptor antagonist approved for insomnia, has demonstrated potential benefits in Alzheimer’s therapy in preclinical studies by reducing harmful tau accumulation while preserving synaptic structure, though it is not approved for this use.
Translating these insights into practice will require multidisciplinary collaboration and carefully designed clinical trials. As clinicians refine diagnostic criteria to identify early glial activation and tau pathology, incorporating protein-targeted agents and sleep interventions into existing care pathways may provisionally redefine treatment algorithms for Alzheimer’s and related neurodegenerative conditions. The principles underlying gliosis control and tau reduction are equally relevant to Parkinson’s disease and other disorders marked by neuroinflammation, underscoring the broader impact of these innovations on patient outcomes.
