IL-15 Complexes Combined with PD-1 Blockade Affect Immune Cell Distribution, Localization, and Immune Signatures in Regressing Versus Non-Regressing Metastatic Breast Tumors.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Rapid advancements in understanding how the immune system can eliminate tumors have quickly translated into breakthroughs in developing cancer therapeutics. Immune checkpoint inhibitors (ICIs) have shown great promise in several cancers; however, resistance can affect up to two-thirds of patients receiving ICIs. A significant limitation of the effectiveness of anti-PD-1 therapy centers around the insufficient levels of immune cells needed to recognize and kill cancer cells compared to the number of suppressive immune cells within the tumor microenvironment. Determining what is required to overcome the resistance to anti-PD-1 therapy in breast cancer remains a critical need. Our data demonstrate that IL-15 complexes injected intratumorally in combination with PD-1 blockade therapy induce regression of established luminal B mammary breast tumors. We show that IL-15 alone or in combination with anti-PD-1 drives changes in gene expression of pathways associated with TCR and co-stimulatory signaling, immune cell adhesion, and migration. Furthermore, we show that intratumoral injection of IL-15 complexes traffics to the tumor-draining lymph node, as evidenced by Light sheet microscopy, and colocalizes with the anti-PD-1 monoclonal antibody. We also identify the immune signatures, localization, and distribution of immune cells in regressing and non-regressing breast tumors.
