Chemokine receptor CCR1 restrains adipose tissue remodelling via cAMP/PKA/CREB signalling and adipocyte‒macrophage crosstalk in mice.
(PubMed, Clin Transl Med)
- "CCR1 expression is significantly elevated in adipose tissue of obese individuals. Systemic and adipocyte-specific Ccr1 deletion promotes fat browning via cAMP/PKA/CREB activation and M2 macrophage polarisation, protecting against obesity. Pharmacological blockade of CCR1 suppresses obesity progression, highlighting its potential as a novel target for metabolic disorders."

Fluid sparing effects of chemokine (C-C motif) receptor 1 and 2 antagonists during resuscitation from hemorrhagic shock in rat models.
(PubMed, PLoS One)
- "Series 2: BX471 and INCB3284 treatment did not affect survival times. Our findings confirm fluid sparing effects of BX471 and INCB3284 over 6h of resuscitation, suggest that both drugs exert comparable efficacy to reduce fluid requirements and modulate the systemic inflammatory response to hemorrhage and fluid resuscitation."

Aging-Associated CCL8+ Senescent Macrophages Recruit CCR1+ Neutrophils to Promote NETs Formation and Impair Meningeal Lymphatic Drainage.
(PubMed, Aging Dis)
- "Importantly, pharmacological inhibition of CCR1 with BX471 or enzymatic degradation of NETs with DNase I restores meningeal lymphatic function and ameliorates spatial learning and memory deficits in aged mice...In addition, machine learning approaches identify a robust predictive gene signature associated with this senescent macrophage phenotype. Collectively, our findings reveal a previously unrecognized macrophage-neutrophil-NETs axis that links meningeal immunosenescence to meningeal lymphatic dysfunction and cognitive decline and may represent a promising therapeutic target for aging-related neurodegenerative disorders."

Periodontal ligament cells regulate macrophage polarization via CCL7/CCR1 signaling.
(PubMed, J Physiol Pharmacol)
- "In the animal experiment, male Wistar rats were subjected to heavy orthodontic force to establish the orthodontic tooth movement model, with the inhibitor group receiving CCR1 antagonist BX471...The CCL7/CCR1 signaling pathway mediates the interaction between PDLCs and macrophages, promoting M1 polarization and OIRR under orthodontic force. Targeting CCL7/CCR1 may offer a promising therapeutic approach to mitigate OIRR during orthodontic treatment."

Aging-induced decrease in progenitor B cells enhances the osteoclastogenesis of bone marrow macrophages via ROS-activated Fos/CCL3 signaling pathway.
(PubMed, Immun Ageing)
- "Our findings suggest that the elevation of ROS levels within bone marrow microenvironment accelerates immune-senescence of B lymphocytes, characterized by a significant reduction in progenitor B-cell populations, which subsequently activates the Fos/Jun-mediated stress signaling pathway. The cascade ultimately results in the overexpression of CCL3, further promoting osteoclastogenesis of macrophage through CCL3-CCR1 axis. CCR1 antagonist could alleviate pro-inflammatory osteoclast formation, revealing a potential therapeutic target for senile osteoporosis."

- "Finally, the role of the ZBP1-CCL7/CCR1 signaling axis in promoting OSCC progression was evaluated via in vivo recombinant CCL7 protein rescue and CCR1 antagonist (BX471) intervention...This study highlights ZBP1 as crucial for OSCC progression by regulating CCL7 expression in CAFs to activate CCR1 signaling in tumor cells. This provides insights into the regulatory mechanisms within the OSCC microenvironment, offering a potential therapeutic strategy for targeted interventions."

Effect and mechanism of chemokine receptor 1 in airway inflammation in a mouse model of chronic obstructive pulmonary disease.
(PubMed, Exp Lung Res)
- "The COPD model mice exhibited significantly increased expression levels of p-IKK, p-JAK2, STAT3, and p-p65 and chemokine concentrations (MIP-1β, IL-6 and TNF-α) than the control mice (p < 0.05), which were further aggravated by overexpressed-CCR1 lentiviral transfection but inhibited by shRNA-CCR1 lentiviral transfection or BX471 pretreatment (p < 0.05). CCR1 aggravates the progression of COPD mice by activating JAK/STAT3/NF-κB signaling. This study has the potential to provide theoretical evidence for the diagnosis and therapeutic strategies of cigarette smoke-induced inflammation in COPD patients."

Tumor-derived CCL5 recruits CCR1+ macrophages to suppress apoptosis and drive proliferation in duodenal adenocarcinoma.
(PubMed, Cancer Lett)
- "Functional assays demonstrated that CCL5 promoted CCR1+ macrophage migration, an effect suppressed by both the CCR1 antagonist BX471 and CCL5-neutralizing antibody...Together, our findings establish the CCL5/CCR1 axis as a key mediator of tumor-macrophage crosstalk in DA, supporting immune evasion and chemoresistance via suppression of macrophage-induced apoptosis. Targeting this axis may represent a promising therapeutic strategy to enhance the efficacy of conventional chemotherapy in DA."

Stress Promotes Lung Metastasis in Breast Cancer by Altering Neutrophil Differentiation.
(PubMed, Cancer Res)
- "Targeting this axis using an anti-Ly6G antibody to deplete neutrophils, a CRISPR/Cas9-mediated approach to conditionally knockout Ccl3/Ccl4 in neutrophils, and BX471 treatment to inhibit CCR1 in cancer cells all significantly reduced breast cancer lung metastasis. Together, this study not only demonstrates a stress-neutrophil-cancer axis that promotes lung metastasis in breast cancer but also provides potential strategies for reducing lung metastasis by targeting CSP neutrophils or CCR1+ breast cancer cells."

The Mechanism of Immunotherapeutic Resistance in Pulmonary Sarcomatoid Carcinoma
(IASLC-WCLC 2025)
- "Experimental mice were divided into four groups, with the exposure of following drugs: IPG1576 (MIF inhibitor; 10 mg/kg, i.p., q2d), BX471 (CCR1 antagonist; 50 mg/kg, s.c., q2d), Camrelizumab, Ociperlimab and Maraviroc [CCR5 antagonist] (all 10 mg/kg, i.p., q3d). In humanized PDX models (Fig.1M), the CCR1/CCR5 inhibitor combination (G4) outperformed MIF inhibitor/ anti-TIGIT (G3) (Figs.1O-P), reversing resistance by increasing precursor-exhausted and reducing terminal-exhausted CD8+ T cells (Fig.1Q). These findings identify CCR1/CCR5 blockade as a novel strategy to reverse immunotherapeutic resistance in PSC Conclusions : The additional combination of CCR1/CCR5 blockade with anti-PD-1 demonstrated a synergistic efficacy to immunotherapy-resistant tumors via reshaping the microenvironment, potentially offering a novel approach to combat immunotherapy resistance in PSC."

The CCR1 chemokine axis plays a major role in recruiting disease-causing immune cells to the skin. Blocking this axis with antagonists may help protect against the development of CLE in our mouse model."

CCR1 inhibition sensitizes multiple myeloma cells to glucocorticoid therapy.
(PubMed, Pharmacol Res)
- "We show that blocking CCR1 signaling with the antagonist BX471 enhances the anti-MM effects of the glucocorticoid dexamethasone in MM cell lines, primary patient material and a myeloma xenograft mouse model. Our findings suggest that CCR1 may play a role in glucocorticoid resistance, as the GC-induced downregulation of CCR1 mRNA and protein is blunted in a GC-resistance onset model. Moreover, we demonstrate that inhibiting CCR1 partially reverses this resistance, providing a promising strategy for resensitizing MM cells to GC treatment."

Gram-negative microflora discrepancy facilitates tumor progression and immune evasion by activating CCL3/CCL5-CCR1-MAPK-PD-L1 pathway in esophageal squamous cell carcinoma
(AATS-ITSOS 2024)
- "Human ESCC cells KYSE150 and TE1 were co-cultivated with Jurkat cells with different lipopolysaccharide (LPS) or BX471 concentrations to examine the effect of G- bacterial flora on the occurrence of ESCC and immune escape... Our results revealed that Gram-negative microflora dysbacteriosis can induce immune evasion in ESCC. LPS accumulation in ESCC microenvironment upregulated CCL3/CCL5 -CCR1-MAPK-PD-L1 pathway and promoted both tumor malignant biological behavior and T cell exhaustions."
