Anti-neuroinflammatory and Neuroprotective Effects of T-006 on Alzheimer's Disease Models by Modulating TLR4-Mediated MyD88/ NF-κB Signaling.
Article in CNS & neurological disorders drug targets, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionNeuroinflammation derived from the activation of the microglia is considered a vital pathogenic factor of Alzheimer's Disease (AD). T-006, a tetramethylpyrazine derivative, has been found to alleviate cognitive deficits via inhibiting tau expression and phosphorylation in AD transgenic mouse models. Recently, T-006 has been proven to dramatically decrease the levels of total Amyloid β (Aβ) peptide and Glial Fibrillary Acidic Protein (GFAP) and suppress the expression of ionized calcium binding adaptor molecule-1 (Iba-1) in APP/PS1 mice. Therefore, we have further investigated the effects of T-006 on neuroinflammation in AD-like pathology.
methodsThe anti-inflammatory effects of T-006 and its underlying mechanisms were evaluated in Lipopolysaccharide (LPS)-induced AD rats. The potential protective effects against LPS-activated microglia-mediated neurotoxicity were also measured.
resultsT-006 significantly improved the cognitive impairment in LPS-induced AD rats by inhibiting the microglia/astrocyte activation. Further cellular assays found that T-006 significantly reserved the anomalous elevation of inflammatory cytokines in LPS-induced BV2 microglial cells in a concentration-dependent manner, while T-006 treatment alone showed no effects on the normal cultured cells. T-006 also reduced the levels of Toll-like Receptor 4 (TLR4)/Myeloid Differentiation protein-88 (MyD88)/NF-κB signaling-related proteins in BV2 cells exposed to LPS stimulation. TAK242, which selectively inhibits TLR4, slightly lessened the effects of T-006 in LPS-treatment BV2 cells without significance. Importantly, T-006 protected neurons against LPS-induced neuroinflammation by inhibiting the Reactive Oxygen Species (ROS) production and maintaining mitochondrial function.
conclusionT-006 inhibited TLR4-mediated MyD88/NF-κB signaling pathways to suppress neuroinflammation in the LPS-induced AD rat model.
