Abstract

Background: The role of the microglia‐related gene triggering receptor expressed in myeloid cells 2 (TREM2) in primary tauopathies, such as progressive supranuclear palsy (PSP), still remains unclear. Objectives: The objective of this study was to profile overall and transcript‐specific TREM2 expression levels in the substantia nigra (SN) of PSP patients and controls. Methods: SN samples from neuropathologically confirmed PSP cases (n = 24) and controls (n = 14) were used to measure TREM2 and TREM2‐modulating gene Membrane‐spanning 4‐domains subfamily A member 4A (MS4A4A) mRNA levels by real‐time quantitative polymerase chain reaction. Correlation with hyperphosphorylated tau protein burden was assessed. Results: Overall TREM2 and each of the 3 TREM2 transcripts mRNA levels were significantly increased in the SN of PSP cases versus controls. TREM2 mRNA levels positively correlated with hyperphosphorylated tau burden in SN, specifically in neurons. The MS4A4A gene was also upregulated in PSP patients versus controls. Conclusions: These results add evidence to the involvement of microglia in the disease process of PSP. These findings support the idea that different tauopathies may share common patterns of deregulation in innate immune molecular pathways. © 2020 International Parkinson and Movement Disorder Society

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.
