The Pathogenesis in Alzheimer's Disease: TREM2 as a Potential Target
Guangtong Liu, Linlin Zhang, Yongzhao Fan, Wenliang Ji. Journal of integrative neuroscience, 2023-10-30
Topic: Inflammation, microglia and astrocytes
Alzheimer's disease (AD) is ranked as the third-most expensive illness and sixth leading cause of mortality. It is associated with the deposition of extracellular amyloid-β (Aβ) in neural plaques (NPs), as well as intracellular hyperphosphorylated tau proteins that form neurofibrillary tangles (NFTs). As a new target in regulating neuroinflammation in AD, triggering receptor expressed on myeloid cells 2 (TREM2) is highly and exclusively expressed on the microglial surface. TREM2 interacts with adaptor protein DAP12 to initiate signal pathways that mainly dominant microglia phenotype and phagocytosis mobility. Furthermore, TREM2 gene mutations confer increased AD risk, and TREM2 deficiency exhibits more dendritic spine loss around neural plaques. Mechanisms for regulating TREM2 to alleviate AD has evolved as an area of AD research in recent years. Current medications targeting Aβ or tau proteins are unable to reverse AD progression. Emerging evidence implicating neuroinflammation may provide novel insights, as early microglia-related inflammation can be induced decades prior to the commencement of AD-related cognitive damage. Physical exercise can exert a neuroprotective effect over the course of AD progression. This review aims to (1) summarize the pathogenesis of AD and recent updates in the field, (2) assess the concept that AD cognitive impairment is closely correlated with microglia-related inflammation, and (3) review TREM2 functions and its role between exercise and AD, which is likely to be an ideal candidate target.

How this study scored 41/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 23 of the 56 points we could judge it on, which is 41 out of 100.
