Abstract

Neuroinflammation commences decades before Alzheimer’s disease (AD) clinical onset and represents one of the earliest pathomechanistic alterations throughout AD its continuum. Large-scale genome-wide association studies point out several genetic variants - TREM2, CD33, PILRA, CR1, MS4A, CLU, ABCA7, EPHA1, and HLA-DRB5-HLA-DRB1 - potentially linked to neuroinflammation. Most of these genes are involved in proinflammatory intracellular signaling, cytokines/interleukins cell turn-over, synaptic activity, lipid metabolism, and vesicle trafficking. Proteomic studies indicate that a plethora of interconnected aberrant molecular pathways, set off and perpetuated by TNF-α, TGF-β, IL-1β, and the receptor protein TREM2, are involved in neuroinflammation. Microglia and astrocytes are key cellular drivers and regulators of neuroinflammation. Under physiological conditions, they are important for neurotransmission and synaptic homeostasis. In AD, there is a turning point throughout its pathophysiological evolution where glial cells sustain an overexpressed inflammatory response that synergizes with amyloid-β and tau accumulation, and drives synaptotoxicity and neurodegeneration in a self-reinforcing manner. Despite a strong therapeutic rationale, previous clinical trials investigating compounds with anti-inflammatory properties, including non-steroidal anti-inflammatory drugs (NSAIDs) did not achieve primary efficacy endpoints. It is conceivable that study design issues, including the lack of diagnostic accuracy and biomarkers for target population identification and proof-of-mechanism may partially explain the negative outcomes. However, a recent meta-analysis indicates a potential biological effect of NSAIDs. In this regard, candidate fluid biomarkers of neuroinflammation are under analytical/clinical validation, i.e. TREM2, IL-1β, MCP-1, IL-6, TNF-α receptor complexes, TGF-β, YKL-40. PET radio-ligands are investigated to accomplish in-vivo and longitudinal regional exploration of neuroinflammation. Biomarkers tracking different molecular pathways (body fluid matrixes) along with brain neuroinflammatory endophenotypes (neuroimaging markers), can untangle temporal-spatial dynamics between neuroinflammation and other AD pathophysiological mechanisms. Robust biomarker-drug co-development pipelines are expected to enrich large-scale clinical trials testing new-generation compounds active, directly or indirectly, on neuroinflammatory targets and displaying putative disease-modifying effects: novel NSAIDs, AL002 (anti-TREM2 antibody), anti-Aβ protofibrils (BAN2401), and AL003 (anti-CD33 antibody). As a next step, taking advantage of breakthrough and multimodal techniques coupled with a systems biology approach is the path to pursue for developing individualized therapeutic strategies targeting neuroinflammation under the framework of precision medicine.

  • Mitochondrial dysfunction-with ROS accumulation and neuroinflammation driving microglial activation-plays a central role in AD pathogenesis.

    “mitochondrial dysfunction—with reactive oxygen species (ROS) accumulation and neuroinflammation driving microglial activation—plays a central role in AD pathogenesis [56]”

    From Theranostic Nanoplatforms for Alzheimer's Disease: A Critical Analysis of Conceptual Contradictions (2026) · cites this paper as [56]

    The ‘Cellular and Molecular Neuroinflammatory Pathways’ section links oxidative stress, neuroinflammation, microglia and ROS in AD; the ‘Role of Microglia’ section also describes harmful microglial activation. But the paper does not identify mitochondrial dysfunction as central to this pathway, and it describes activated microglia producing ROS rather than ROS driving their activation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
