Abstract
Highlights What are the main findings? NETs contribute to neuroinflammation by promoting blood–brain barrier disruption and the amplification of inflammatory signaling in several neurodegenerative diseases. Dysregulated NET formation is increasingly recognized as a mechanistic link between innate immune activation and neuronal injury in neurodegenerative disorders such as Alzheimer’s disease, Parkinson’s disease, and multiple sclerosis. What are the implications of the main findings? Targeting the NETosis pathways represents a promising therapeutic strategy to modulate neuroinflammation and reduce neurovascular damage in neurodegenerative disorders. Emerging approaches, including PAD4 inhibition, DNase-mediated NET degradation, and modulation of oxidative signaling pathways, may provide new avenues for therapeutic intervention. Abstract Neuroinflammation is a complex process involved in the pathogenesis of several neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, Huntington’s disease, and amyotrophic lateral sclerosis. Neutrophils, although traditionally considered peripheral immune cells, have emerged as active participants in the immunopathology of the central nervous system (CNS) through the release of neutrophil extracellular traps (NETs), structures composed of decondensed chromatin embedded with pro-inflammatory proteins. Evidence suggests that NETs play a dual role: they are protective against pathogens but can also induce tissue damage when produced in excess. Several pathways are involved in their formation, including vesicle-mediated release (vital NETs), the lytic NADPH oxidase (NOX)-dependent pathway, and the mitochondrial pathway. Targeting NETs therapeutically, through the use of NETosis inhibitors, NET-degrading strategies, or blockade of neutrophil migration, has shown promise in reducing neuroinflammation/neurodegeneration and improving neurological outcomes in experimental models. This review aims to investigate both the protective and deleterious roles of NETs and how this knowledge may reveal new therapeutic strategies to modulate neurodegenerative diseases and preserve neural integrity, offering valuable insights for potential applications in clinical practice.
New knowledge about the protective and detrimental aspects of neuroinflammation in AD and PD is summarized, providing an analysis on these developing prospects for targeted interventions toward slowing or stopping neurodegeneration.

Neurodegenerative diseases represent a major global public health challenge, imposing substantial societal and economic burdens. Their complex pathogenesis and limited therapeutic options underscore an urgent need for new paradigms. Emerging evidence indicates that dysregulation of the brain's immune microenvironment is a critical driver of disease progression. Conventional wisdom posits that peripheral immune cells and central glial cells serve as the primary initiators of neuroimmune responses, whereas neurons are regarded merely as passive recipients of inflammatory damage. Emerging evidence suggests that upon receiving pathological signals in the central nervous system, neurons may become more vulnerable and participate in the onset of neuroimmune processes, positioning them as potential targets for early intervention in neurodegenerative diseases. This article systematically reviews the contribution of neuron-derived immune-inflammatory responses in neurodegenerative diseases and potential intervention strategies. We first outline the capacity of neurons to regulate neuroimmune responses and detail the underlying molecular mechanisms. Then we compare the specific mechanisms by which neurons with different susceptibility drive and amplify neuroinflammation in various neurodegenerative diseases such as alzheimer's disease, parkinson's disease, amyotrophic lateral sclerosis, vascular cognitive impairment, and transformed these mechanisms into intervention strategies targeting neurons,. This article aims to break through the traditional concept of passive neuronal damage, systematically integrate intervention strategies that shift from targeting peripheral immune and glial cells to regulating neuron-derived immunity, thereby providing a new theoretical framework for overcoming current clinical limitations and identifying effective therapeutic targets for the prevention and treatment of neurodegenerative diseases.

It is illustrated how endogenous pathological triggers, such as amyloid-β (Aβ) peptide, hyperphosphorylated tau, and α-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration.
This review consolidates current evidence regarding the mechanisms by which polyphenols modulate microglial phenotypic balance and polarization states and examines advanced delivery strategies designed to enhance their therapeutic efficacy in neuroinflammatory disorders.
The objective is to elucidate the context-dependent roles of TREM2 by analyzing consensus mechanisms, sources of discrepancy, and translational implications, thereby providing a theoretical framework and strategic direction for more precise TREM2-targeted interventions.
