Spatially Resolved Transcriptomics Reveal Macrophage Heterogeneity in Giant Cell Arteritis
(ACR Convergence 2025)
- "In vitro functional analyses included THP-1-derived macrophages cultured and a TREM-1 inhibition assay using nangibotide. Spatial transcriptomics showed TREM-1 signaling among top upregulated pathways in media-infiltrating CD68⁺ macrophages from GCA lesions, alongside Th1, IL-6, and interferon signaling pathways, and identified IFN-γ and TLR activation as major upstream regulators using Ingenuity Pathway Analysis... TREM-1 and TREM-2 define distinct macrophage subsets in GCA. TREM-1 is associated with inflammation and monocyte recruitment, while TREM-2 may mediate homeostatic functions. These findings position TREM-1 as a promising therapeutic target."

The role of Toll-like receptors in liver regeneration after partial hepatectomy.
(PubMed, Prz Gastroenterol)
- "One group of each type was sacrificed at 12 h (LR12 and Sh12), 24 h (LR24 and Sh24), 36 h (LR36 and Sh36), and 168 h (LR168 and Sh168)...TLR expression was significantly higher in mice that underwent partial hepatectomy than the controls. Further research is required to investigate their potential as therapeutic targets in the management of acute or chronic liver failure after partial hepatectomy."

Mechanism of TREM1-regulated pro-inflammatory polarization in macrophages mediating voriconazole-induced liver injury
(IDDF 2025)
- "TREM1 inhibitor LR12 could attenuate hepatic inflammation and steatosis, suppressing PI3K/AKT-NFκB-NLRP3 signaling axis activation while restoring lipid metabolic homeostasis.Download figure Open in new tab Download powerpoint Abstract IDDF2025-ABS-0173 Figure 1 Graphical abstractConclusions This study identified TREM1-mediated macrophage inflammatory polarization through the TLR4-PI3K/Akt-NFκB-NLRP3 signaling axis, concurrently promoting hepatic steatosis. These findings identify TREM1 as a potential diagnostic biomarker and therapeutic target for DILI. Preclinical evidence confirms the efficacy of TREM1 inhibitors in animal models, providing a theoretical basis for the development of targeted drugs."

Ligand-Independent TREM-1 Blockade Ameliorates Pulmonary Inflammation and Fibrosis
(ATS 2025)
- "Multiplicity and promiscuity of TREM-1 ligands significantly increase the risk of failure of traditional, ligand-dependent approaches to TREM-1 inhibition (e.g., anti-TREM-1 blocking antibodies and decoy peptides) in clinical efficacy testing. Despite promising preclinical data and safety in humans, the first clinical inhibitor of TREM-1, a decoy peptide LR12 (nangibotide), failed in phase IIb sepsis trial... Ligand-independent TREM-1 blockade for the first time has been shown to ameliorate pulmonary inflammation and fibrosis in animal models, warranting further development of a novel, first-in-class TREM-1 therapy for human ARDS and PF."

Stearyl amine coated liposome of rotigotine alleviates cognitive deficit in Parkinson's disease induced mice model: modulation of oxidative stress, and motor coordination.
(PubMed, Drug Dev Ind Pharm)
- "The study was conducted to evaluate the brain targeted delivery of cationic liposomes of rotigotine via nasal route, addressing the limitations in brain penetration for Parkinson's disease intervention...The optimized liposome, LR12, was surface modified with stearylamine at three concentrations to confer a cationic charge...The cationic liposome RTG-LP3 demonstrated effective delivery of liposomes with superior therapeutic effects in treating PD via nasal route. These findings highlight the potential of cationic liposomes as a viable method for improving brain penetration and neuroprotection in PD therapy."

Recent advances of precision immunotherapy in sepsis.
(PubMed, Burns Trauma)
- "Suggested strategies to attenuate the immune responses are anakinra, nangibotide and tocilizumab...Suggested strategies to restore SII are nivolumab, recombinant human interferon-gamma, CYT107, granulocyte macrophage colony stimulating factor and IgM-enriched immunoglobulin prepapations. Biomarkers that guide their use are the expression of the human leukocyte antigen DR on blood monocytes, the absolute lymphocyte count and blood levels of immunoglobulin M. One recently suggested strategy to restore vascular tone is adrecizumab, the use of which is guided by blood levels of bio-adrenomedulin. The use of these precision treatment strategies is still hampered by the need for large-scale randomized controlled trials."

Enhancing sepsis biomarker development: key considerations from public and private perspectives.
(PubMed, Crit Care)
- "Biomarker-guided interventions for sepsis to identify patients that would benefit more from therapy, such as sTREM-1-guided Nangibotide treatment or Adrenomedullin-guided Enibarcimab treatment, appear promising but require further evaluation. Artificial intelligence also has great potential in the sepsis biomarker discovery field through capability to analyse high volume complex data and identify complex multiparametric patient endotypes or trajectories. To conclude, biomarker development in sepsis requires (i) a comprehensive and multidisciplinary approach employing the most advanced analytical tools, (ii) the creation of a platform that collaboratively merges scientific and commercial needs and (iii) the support of an expedited regulatory approval process."

Targeting Oncostatin M Receptor to Attenuate Carotid Artery Plaque Vulnerability in Hypercholesterolemic Microswine.
(PubMed, Cardiol Cardiovasc Med)
- "OSM and p27KIP1 expression in carotid arteries with angioplasty and treatment with either scrambled peptide or LR12, an inhibitor of triggering receptor expressed on myeloid cell (TREM)-1, were compared between the experimental groups and with contralateral carotid artery. The results of this study elucidated the presence of OSM and p27KIP1 in carotid arteries with plaque and their association with arterial plaque and vulnerability. The findings suggest that targeting OSM and p27KIP1 axis regulating VSMC proliferation may have therapeutic significance to stabilize plaque."

Development of TREM-1 Inhibitors: A Novel Treatment for Neuroinflammation
(CAP 2023)
- "Design: In exploring hearing loss, 42 mice that were 6 to 8 weeks of age were exposed to 106 decibels (dB) of noise for 2 hours and transtympanically injected with a single dose of one of the TREM-1 inhibitors (peptide LR12), small molecules (GJ073 or GJ004), or a control substance (hydrogel)... This study offers insight into the possible role of TREM-1, GJ073, and GJ004 in neuroinflammatory pathways. The difference in recovery of hearing thresholds could indicate differences in drug efficacy or potency and guide development of therapeutic interventions."

TREM-1 triggers necroptosis of macrophages through mTOR-dependent mitochondrial fission during acute lung injury.
(PubMed, J Transl Med)
- "In this study, we reported that TREM-1 acted as a necroptotic stimulus of AlvMs, fueling inflammation and aggravating ALI. We also provided compelling evidence suggesting that mTOR-dependent mitochondrial fission is the underpinning of TREM-1-triggered necroptosis and inflammation. Therefore, regulation of necroptosis by targeting TREM-1 may provide a new therapeutic target for ALI in the future."

TREM-1 exacerbates bleomycin-induced pulmonary fibrosis by aggravating alveolar epithelial cell senescence in mice.
(PubMed, Int Immunopharmacol)
- "Herein, we report that the prophylactical blockade of TREM-1 using a decoy peptide dodecapeptide (LR12) exerted protective effects against BLM-induced PF in mice, with a higher survival rate, attenuated tissue injury, and less extracellular matrix deposition. Furthermore, prophylactic or therapeutic blockade of TREM-1 protected MLE12 cells from senescence induced by BLM or HO. In conclusion, our findings elucidate a pro-fibrotic effect of TREM-1 by inducing AECs senescence in PF, providing a potential strategy for fibrotic disease treatment."

TREM-1 induces pyroptosis in cardiomyocytes by activating NLRP3 inflammasome through the SMC4/NEMO pathway.
(PubMed, FEBS J)
- "In mice subjected to caecal ligation and puncture, the TREM-1 inhibitor LR12 decreased the expression of NLRP3 and attenuated cardiomyocyte pyroptosis, leading to improved cardiac function and prolonged survival of septic mice. Our work demonstrates that, under septic conditions, TREM-1 plays a critical role in cardiomyocyte pyroptosis. Targeting TREM-1 and its associated molecules may therefore lead to novel therapeutic treatments for septic cardiomyopathy."
