A systematic review of the role of TREM2 in Alzheimer's disease
Yin Y, Yang H, Li R, Wu G, Qin Q, Tang Y.. Chinese medical journal, 2024-06-24
Topic: Amyloid, tau and blood-test diagnosis
Background Given the established genetic linkage between triggering receptors expressed on myeloid cells 2 (TREM2) and Alzheimer's disease (AD), an expanding research body has delved into the intricate role of TREM2 within the AD context. However, a conflicting landscape of outcomes has emerged from both in vivo and in vitro investigations. This study aimed to elucidate the multifaceted nuances and gain a clearer comprehension of the role of TREM2. Methods PubMed database was searched spanning from its inception to January 2022. The search criteria took the form of ("Alzheimer's disease" OR "AD") AND ("transgenic mice model" OR "transgenic mouse model") AND ("Triggering receptor expressed on myeloid cells" OR "TREM2"). Inclusion criteria consisted of the following: (1) publication of original studies in English; (2) utilization of transgenic mouse models for AD research; and (3) reports addressing the subject of TREM2. Results A total of 43 eligible articles were identified. Our analysis addresses four pivotal queries concerning the interrelation of TREM2 with microglial function, Aβ accumulation, tau pathology, and inflammatory processes. However, the diverse inquiries posed yielded inconsistent responses. Nevertheless, the inconsistent roles of TREM2 within these AD mouse models potentially hinge upon factors such as age, sex, brain region, model type, and detection methodologies. Conclusions This review substantiates the evolving understanding of TREM2's disease progression-dependent impacts. Furthermore, it reviews the interplay between TREM2 and its effects across diverse tissues and temporal stages.

Why it matters
This systematic review gathered 43 studies of TREM2, an immune receptor on microglia, in mouse models of Alzheimer's. Results on how TREM2 affects microglia, amyloid, tau and inflammation were inconsistent, possibly depending on age, sex, brain region, model type and lab methods. The authors conclude TREM2's effects likely change with disease stage, which matters for anyone hoping to target it as a treatment.
