Repression of microglial primary cilia in 5xFAD mice (A) Representative images of AC3 (green)-positive microglia (MG) stained for Iba1 (red) in the LS and the cortex of WT and 5xFAD mice (6-month-old). In 5xFAD mice, A beta plaques were stained using 6E10 antibodies (white). (B) Plots depict the percentage of AC3-positive microglia and the length of AC3-stained primary cilia, respectively. Images were taken from the LS (1024 ㎛2) and the cortex (1024 ㎛2) of WT and 5xFAD mice (5-month-old, n = 4, each group, male) (C) Western blot analysis shows the differential expression of the homeostatic microglial markers in BV2 cells, which were harvested 24 h after transfection with siIft88. Plots represent protein expression normalized by alpha -tubulin ( alpha Tub, n = 3). (D) Western blot analysis shows the differential expression of the DAM markers in BV2 cells transfected with siIft88 for 24 h. Plots represent protein expression normalized by alpha Tub (n = 3). (B–D) Data represent means +/- SEM, and p-values were calculated by an unpaired two-tailed t-test. ****p < 0.0001, ***p < 0.001, **p < 0.01, *p < 0.05, ns (non-significant). Scale bars = 10 um.

Background: TREM2
TREM2 is upregulated under many pathological conditions and has been of particular interest in neurodegenerative disorders like Alzheimer's disease (AD) where it helps activate microglial responses (1-3,5). Studies have found that sTREM2 is typically elevated in the cerebral spinal fluid (CSF) of AD patients compared to healthy counterparts and may serve as a biomarker of AD (2). While TREM2-mediated microglial activation is considered beneficial in some disease contexts (e.g. demyelinating diseases, ischemia), it is detrimental in others (e.g. peripheral nerve injury) and may be dependent on disease stage, as observed in AD (2,5). Microglia promote amyloid-beta (Abeta) clearance, phagocytosis and reduce tau proliferation in the early stages of AD but can increase Abeta accumulation and tau propagation in late stages of AD (2). Recent studies have also suggested a role for TREM2 in cancer, where it supports an immune-suppressive tumor microenvironment such as reduced of T cell proliferation (1,6). Therapeutic targeting of the TREM2 pathway can be directed towards ligand binding to downstream signaling (1). Potential therapeutic strategies include using monoclonal antibodies or small molecules to either enhance or block signaling (1,6). While more work needs to be done, initial studies targeting TREM2 for cancer immunotherapy is promising (6).
