Pharmacologic targeting of the dopamine D2 receptor impacts the efficacy of immune checkpoint blockade in melanoma

Background
Immune checkpoint inhibitors (ICIs) have been successful in treating advanced melanoma, yet, the 10-year melanoma-specific survival is only 52%. Our prior work using genetic linkage analysis revealed that the murine prolactin (PRL) locus as…

Telmisartan increases olaparib efficacy in homologous recombination proficient tumors by augmenting type I interferon production

Background
Poly-ADP ribose polymerase inhibitors (PARPi) are well-known to treat tumors that are deficient in homologous recombination (HR) DNA repair. However, PARPi can treat breast cancer gene (BRCA) wild-type tumors, the mechanisms behind which ar…

Targeted inhibition of Nrf2 potentiates antitumor immunity and enhances the efficacy of immunotherapy in hepatocellular carcinoma

Background
Immune checkpoint inhibitors (ICIs) and chimeric antigen receptor T-cell (CAR-T) immunotherapies have revolutionized the treatment of hepatocellular carcinoma (HCC). However, the frequent emergence of treatment resistance significantly limi…

Single-cell-based identification of drug synergy with immunotherapy via tumor microenvironment remodeling

Background
Identifying effective therapeutic drugs in the intricate tumor microenvironment (TME) is challenging, further complicated by the lack of a systematic framework for analyzing TME perturbations in response to therapeutic interventions.

Metho…

Dual regulation of CXCR6+CD8+ T cells modulates cytotoxic and exhaustion-associated programs during prostate cancer progression

Background
Prostate cancer (PCa) is widely recognized as an immunologically “cold” tumor, characterized by a paucity of effector T cells and a limited response to immune checkpoint blockade therapy. Although the chemokine receptor CXCR6 has been ident…

Fluorination augments tumor engagement and antitumor immunity of a D-peptide-based radiotheranostic agent for combinatorial immune checkpoint blockade therapy

Background
Programmed death-ligand 1 (PD-L1)-targeted radiopharmaceutical therapy (RPT) combined with immune checkpoint blockade (ICB) represents a promising combinatorial treatment because of the “magic” bystander and abscopal effects of RPT. However…

Hyaluronic acid-CD44 signaling defines therapeutic resistance and immunosuppressive microenvironment in peritoneal metastasis of gastric cancer

Background
Peritoneal metastasis (PM) is one of the most challenging clinical problems in gastric cancer (GC), largely due to its high recurrence rate and poor response to current therapies. Increasing evidence indicates that remodeling of the extrace…

Integrating interferon gamma receptor pathways, antigenicity, and immune contexture as predictors of immunotherapeutic strategies for mucosal melanomas

Background
Mucosal melanomas (MM) arise from mucosal melanocytes at various anatomical sites. These tumors are rare, highly aggressive, and often associated with poor outcomes. Current treatments, including immune checkpoint inhibitors, show limited e…

Antibiotic-associated dysbiosis and bispecific antibody outcomes in multiple myeloma

Background
The gut microbiota plays a critical role in regulating immune homeostasis and modulating responses to cancer immunotherapies. However, the impact of antibiotic-induced dysbiosis in patients with multiple myeloma (MM) treated with bispecific…

Antibody therapeutics with high affinity for Fc{gamma}Rs exacerbate anaphylaxis via Fc{gamma}R-mediated capture by tumor-associated myeloid cells

Background
Antibody therapeutics have revolutionized cancer treatment, but their use is increasingly associated with adverse events. Among these, anaphylaxis is particularly concerning due to its severity and unpredictability. Our previous studies dem…
