Targeting non-canonical antigens unlocks functional T-cell responses in renal cell carcinoma

Background
Renal cell carcinoma (RCC) frequently exhibits favorable responses to immunotherapy, despite a low tumor mutational burden, suggesting a critical role for non-mutational antigens presented by human leukocyte antigen class I in activating CD…

Spatial immune atlas of breast cancer brain metastasis reveals CD163+ macrophage reprogramming associated with immune escape

Background
Brain metastases (BrM) remain a major cause of mortality in breast cancer (BC), yet the spatial organization and molecular circuitry of the metastatic immune microenvironment are poorly defined.

Methods
To address this gap, we integrated h…

C92, a proton channel-blocking allosteric STING agonist generates robust antitumor activity

Background
The activation of stimulator of interferon genes (STING) for the treatment of cancer is a long-standing therapeutic goal. However, the clinical use of orthosteric STING agonists has shown limited utility in patients with advanced/metastatic…

Dexamethasone activates anti-tumor immunity in multiple myeloma by dismantling the GR-PPP1CB complex to restore STING/IRF3 signaling

Background
The cyclic GMP-AMP synthase/stimulator of interferon genes (cGAS-STING) pathway mediates anti-tumor immunity by sensing cytosolic DNA and producing type I interferons, but is frequently suppressed in multiple myeloma (MM), enabling immune e…

IL-10 secretion by CD8 T cells orchestrates early NK cell recruitment and antitumor immunity after anti-VEGFR-2/PD-1 therapy

Background
The combination of antiangiogenic therapy with immune checkpoint blockade has demonstrated significant clinical benefits in various cancers, however, the precise mechanisms of action on the immune system are not fully understood. In particu…

Activation of tumor-specific CD8+ T cells prior to radiopharmaceutical therapy improves antitumor response

Background
Radiopharmaceutical therapy (RPT) delivers radiation systemically, enabling the treatment of metastatic cancers. Beyond killing tumor cells, RPT can modulate the tumor immune microenvironment. With RPTs and immunotherapies already approved …

Comprehensive characterization of the inflammatory ecosystems in immunotherapy-induced adverse events versus chronic inflammatory diseases

Background
Immune-related adverse events (irAEs) induced by immune checkpoint inhibitors (ICIs) share symptomatic and therapeutic similarities with chronic inflammatory diseases (CIDs). However, the molecular distinctions between irAEs and CIDs remain…

Melanoma cell states shape spatial tumor-immune ecosystems to dictate the efficacy of anti-PD1 immunotherapy

Background
Melanoma shows one of the highest response rates to immune checkpoint inhibitors (ICIs), yet nearly half of patients experience primary or acquired resistance. While immune contexture strongly influences therapeutic efficacy, tumor cell-int…

Blinatumomab bypasses CD28 blockade to sustain T-cell cytotoxicity and improve survival in a xenograft B-ALL model

Background
Relapse and graft-versus-host disease (GvHD) remain primary causes of treatment failure in patients with B-cell acute lymphoblastic leukemia (B-ALL) undergoing allogeneic hematopoietic cell transplantation (allo-HCT). While abatacept (ABATA…
