Partitioned overall survival: comprehensive analysis of survival states over 4 years in CheckMate 9ER comparing first-line nivolumab plus cabozantinib versus sunitinib in advanced renal cell carcinoma

Background
Immune checkpoint inhibitor (ICI)-based regimens can be associated with prolonged survival and disease control after treatment discontinuation without further anticancer therapy. An integrated, comprehensive partitioned survival analysis de…

Targeting PKMYT1 enhances antitumor immune responses to PD-L1 blockade in castration-resistant prostate cancer

Background
Although immunotherapy has revolutionized cancer treatment, its efficacy in castration-resistant prostate cancer (CRPC) remains limited, largely due to an immunologically “cold” tumor microenvironment with scarce T-cell infiltration. Unrave…

Preventing surgery-induced natural killer cell suppression and metastases by inhibiting PI3K-gamma signaling in myeloid-derived suppressor cells

Background
Myeloid-derived suppressor cells (MDSCs) have a dominating presence in the postoperative period, mediating the suppression of natural killer (NK) cells and promoting cancer metastases after surgery. However, their phenotype and effects on p…

Targeting AKR1B1 reprograms tumor-associated macrophages to enhance antitumor immunity

Background
Tumor-associated macrophages (TAMs) are key drivers of the immunosuppressive tumor microenvironment (TME), thereby limiting the efficacy of immune checkpoint inhibitors (ICIs). However, the underlying mechanisms remain unclear.

Methods
Bot…

Tumor neoantigen gene C7orf50 remodels the immune microenvironment by recruiting tumor-associated macrophages to promote hepatocellular carcinoma progression and lung metastasis

Background
Hepatocellular carcinoma (HCC) is a global health challenge with high mortality rates, particularly in patients with advanced disease and lung metastasis. T-cell receptor (TCR)-T cell therapy based on specific neoantigens, is an emerging tr…

RIG-I agonists promote antigen-spreading and facilitate durable CAR-T responses in pancreatic ductal adenocarcinoma

Background
Pancreatic ductal adenocarcinoma (PDAC) remains largely refractory to chimeric antigen receptor (CAR)-T cell therapy. Insufficient T cell infiltration, a highly immunosuppressive microenvironment, and antigen loss pose major challenges for …

Targeting macrophage-derived SPP1 enhances CD8 T cell infiltration via ROS-DNA fragment/cGAS-STING/STAT1-mediated CXCL9/10 in tumor microenvironment

Background
Elevated levels of SPP1+ tumor-associated macrophages (TAMs) are associated with reduced CD8+ T cell infiltration and poorer prognosis in cancer patients, but direct evidence demonstrating a causal role for SPP1+ TAMs in excluding CD8+ T ce…

Non-superagonist CD28-based dual-signal T cell engager targeting

Background
Bispecific T cell engagers have demonstrated promising clinical progress in both hematologic malignancies and solid tumors; however, their therapeutic efficacy is still limited by multiple challenges including T cell anergy resulting from s…

Stearoyl-CoA desaturase-1 controls the differentiation and antitumoral function of Th9 lymphocytes

Background
Stearoyl-CoA desaturase 1 (SCD1) is a key enzyme in fatty acid (FA) metabolism that catalyzes the addition of a cis double bond to palmitic and stearic saturated FAs, producing palmitoleic and oleic monounsaturated FAs, respectively. Interl…
