Ponatinib emerged as the top-ranked computational candidate (mean: - 10.07 kcal/mol), followed by Regorafenib (- 9.64), Sorafenib (- 9.46), and Entrectinib (- 9.45), while non-oncology drugs including antrafenine, betrixaban, and maraviroc demonstrated novel multi-target binding profiles...MM-GBSA calculations revealed a binding hierarchy concordant with docking scores (R2 = 0.92): Ponatinib-VEGFR2 (ΔGbind = - 42.38 kcal/mol) > Entrectinib-CDK6 (- 38.56) > Ponatinib-EGFR (- 33.24) > Entrectinib-HER2 (- 28.47) > Dacomitinib-HDAC3 (- 24.63 kcal/mol)...As the present study is entirely computational, the identified compounds should be regarded as hypothesis generating leads requiring experimental validation through in vitro kinase and HDAC3 inhibition assays, cell based studies, and target engagement confirmation before any translational conclusions can be drawn.

Pharmacological inhibition of CCR5, CXCR2, and IL1R1 with maraviroc, navarixin, and anakinra, respectively, disrupted this cytokine axis, suppressing metastatic colonization in vivo. Our findings reveal that blocking cytokine receptor signaling disrupts the pro-metastatic crosstalk between macrophages and TNBC cells, offering a clinically actionable strategy to restrain metastasis and overcome therapy resistance in TNBC.

Agonists induced transient heteromerization coupled to receptor internalization, while antagonists, especially plerixafor together with maraviroc, stabilized persistent surface-associated complexes. Molecular dynamics simulations in asymmetric bilayers resembling MDA-MB-231 and MCF-10A membranes identified cholesterol-enriched receptor interfaces that prolong CXCR4-CCR5 dimer lifetimes in MDA-like membranes. These results show that GPCR heteromerization is not an intrinsic fixed property of receptor pairs, but an emergent behavior shaped by cell state, lipid environment, and ligand input.

These abnormalities were ameliorated by maraviroc treatment. Collectively, CCL3 interferes with oligodendrocyte maturation, thereby delaying axonal myelination and resulting in neural circuit dysfunction mediated by VPA.

CCL5 promotes radioresistance in HNACC through maintenance of AMPK/mTOR-dependent autophagy. Targeting the CCL5/CCR5 axis enhances radiosensitivity and represents a promising therapeutic strategy.

Importantly, combining CCL5-knockout CAR-T cells with the CCR5 inhibitor maraviroc significantly enhanced antitumor efficacy. These findings reveal a mechanism constraining CAR-T function in solid tumors and suggest promising combination strategies to improve therapeutic outcomes.

During neoantigen vaccination, CCR5 blockade with maraviroc selectively inhibited antigen-bearing moDC migration, enhancing dendritic cell-mediated antitumor immunity. These findings showed how macrophage lineage and spatial compartmentalization govern tumor immunity and identified strategies to preserve protective IM functions, while disrupting macrophage-driven immunosuppression.

Pharmacological modulation of lipid-driven signaling pathways through CCR5 inhibition (inflammation modulation through maraviroc) or blockade of the lipid scavenger receptor CD36 reprograms TAMs, restores T cell activity, and enhances antitumor immune responses within lipid-rich tumor niches...Consistent with these mechanistic insights, we demonstrated that the specific immunometabolic niche in omental metastases is clinically associated with responsiveness to ICB. We propose a non-invasive radiomics and machine-learning-based analysis of imaging data to assess omental involvement for patient stratification.

We further detail past and ongoing therapeutic efforts and trials addressing these axes in both PDAC and relevant non-PDAC settings via several small-molecule antagonists and monoclonal antibodies: BMS-813160, Maraviroc, Leronlimab, FLX475, PF-07054894, IDOR- 1117-2520, and CAP-100. Despite continuous advances in the field, the current body of evidence remains limited and presents significant research gaps in areas such as spatial profiling, stage-specific analyses, and general mechanistic validation in PDAC-specific settings. Addressing these shortcomings will be key to developing a more comprehensive knowledge of the field and improving future therapeutic strategies to overcome PDAC.
