Focused ultrasound thermal ablation and CD40 agonism reprograms breast tumor immunity to drive regression and memory

Background
Focused ultrasound thermal ablation (T-FUS) is a clinically accessible, non-invasive modality capable of inducing rapid tumor cytoreduction while mobilizing early immunologic danger signals. However, its capacity to synergize with potent co…

CXCR2-mediated metabolic interaction between prostate cancer cells and the immunosuppressive tumor microenvironment

Background
Neuroendocrine prostate cancer (NEPC) is characterized by strong immune evasion and profound metabolic reprogramming. A high regulatory T cell (Treg)/CD8+ T cell ratio and an increased proportion of M2/M1 tumor-associated macrophages (TAMs)…

FLT3L-secreting cDC1 in situ vaccination enhances antitumor immunity and synergizes with PD-1 blockade in murine non-small cell lung cancer

Background
Non-small cell lung cancer (NSCLC) frequently evades immune surveillance through defective antigen presentation and a suppressive tumor microenvironment (TME), limiting the efficacy of immune checkpoint blockade (ICB). Conventional type 1 d…

Pancreatic tumor microenvironment reprogramming via alloantigen-expressing virotherapy elicits tumor rejection and improves immunotherapy response

Background
Pancreatic ductal adenocarcinoma (PDAC), the most common malignant type of pancreatic cancer, is characterized by a dense desmoplastic stroma, low neoantigen burden, and a highly immunosuppressive tumor microenvironment (TME).

Methods
We p…

VISTA neutralization by immunization reprograms immunosuppression and augments vaccine efficacy in renal carcinoma

Background
Renal carcinoma remains a highly lethal malignancy, and tumor vaccine efficacy is frequently hampered by a profoundly immunosuppressive tumor microenvironment. V-domain Ig suppressor of T-cell activation (VISTA), an inhibitory immune checkp…

LGALS9 blockade augments vaccine-induced immune responses against prostate cancer

Background
Prostate-specific membrane antigen (PSMA)-based vaccination represents a promising immunotherapeutic strategy for prostate cancer; however, its efficacy remains constrained by tumor-induced immune evasion and insufficient activation of anti…

Oncolytic adenovirus in combination with PD-L1-targeted radioimmunotherapy exerts synergistic antitumor effect against pancreatic cancer

Background
To date, no radioimmunotherapy (RIT) regimen has been approved by US Food and Drug Administration for the treatment of pancreatic cancers. Highly desmoplastic and immune-desert phenotypes of pancreatic cancer remain two major hurdles that a…

Intraperitoneal CF33-hNIS combined with PD-L1 blockade eradicates gastric cancer peritoneal metastases and prevents recurrence via durable T cell memory

Background
Peritoneal metastasis (PM) from gastric cancer (GC) is associated with poor prognosis and limited treatment options. We investigated a novel peritoneal-targeted therapy using CF33-human sodium iodide symporter (hNIS), a chimeric orthopoxvir…

Dual-chemokine-armed oncolytic Senecavirus A co-recruits cDC1 and CXCR3+ T cells to convert ‘cold melanoma and drive durable regression

Background
Oncolytic virotherapy represents a promising anticancer strategy by combining direct tumor lysis with in situ immune activation. However, its efficacy remains limited in immune-cold tumors, which are characterized by poor T-cell infiltratio…

Liver-directed AAV-IL-10 therapy enhances CD8+ T cell-mediated immunity against hepatocellular carcinoma

Background
The liver’s inherently immunosuppressive microenvironment presents a major barrier to effective immunotherapy for hepatocellular carcinoma (HCC). Although interleukin-10 (IL-10) has demonstrated antitumor activity in several cancer mo…
