Targeting the CCL5/CCR5 axis in tumor-stromal crosstalk to overcome cisplatin resistance in neuroendocrine prostate cancer.

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
backgroundNeuroendocrine prostate cancer (NEPC) is an aggressive subtype of prostate cancer with limited therapeutic options. Although cisplatin is recommended as a first-line treatment, its clinical efficacy is hindered by the rapid development of drug resistance, highlighting the urgent need for effective strategies to overcome cisplatin resistance.
methodsWe established a NEPC mouse allograft model and performed RNA sequencing to identify genes associated with cisplatin resistance. The role of CCL5 in tumor-stromal crosstalk was investigated using immunofluorescence, ELISA assays, co-culture assays, and CCL5 knockout mice. Mechanistic studies were conducted to explore CCL5/CCR5-mediated signaling pathways. The therapeutic efficacy of cisplatin combined with maraviroc, an FDA-approved CCR5 antagonist, was evaluated in vitro using NEPC cell lines and patient-derived organoids, and in vivo using NEPC mouse models.
resultsHere, we identify a tumor-stromal interaction mediated by the CCL5/CCR5 axis that drives cisplatin resistance in NEPC. Cisplatin-induced DNA damage promotes a cGAS-STING-dependent senescence program in cancer-associated fibroblasts (CAFs), resulting in the secretion of CCL5, a key senescence-associated secretory phenotype factor. CCL5 from CAFs binds to CCR5 on tumor cells, promoting the formation of a CCR5/β-arrestin1/p85 complex that activates the PI3K/AKT pathway. This activation enhances DNA repair, protecting tumor cells from cisplatin-induced apoptosis. Pharmacologic inhibition of the CCL5/CCR5 pathway using maraviroc, an FDA-approved CCR5 antagonist, sensitizes NEPC cells to cisplatin treatment and significantly prolongs survival in NEPC mouse models.
conclusionsOur findings identify the CCL5/CCR5 axis as a key mediator of tumor-stromal crosstalk driving cisplatin resistance in NEPC. Mechanistically, CAF-derived CCL5 activates AKT signaling in tumor cells by promoting the formation of the CCR5/β-arrestin1/p85 complex. Targeting this pathway with maraviroc in combination with cisplatin offers a promising therapeutic strategy for overcoming drug resistance in NEPC.
