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…

V{delta}1 T-cell subset appears to be responsive to PD-1 blockade therapy and is associated with survival in melanoma

Background
Although most studies of anticancer T-cell immunity focus on αβ T cells, T cells are attracting increasing attention due to their involvement in antitumor immune responses in various cancer entities, including melanoma. While im…

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…

Integrative multiomic profiling of cfDNA methylation and EV-miRNAs identifies immunotherapy-outcome molecular subtypes in NSCLC

Background
Patients with non-small cell lung cancer (NSCLC) exhibit heterogeneous responses to immunotherapy (IT) with high resistance rates, highlighting the need for precise biomarkers of treatment outcomes.

Methods
In a prospective cohort study, w…

CAR T cells: the missing piece needed to improve outcomes for children with cancer?

B cell acute lymphoblastic leukemia (B-ALL) is the most common cancer of childhood. Outcomes for B-ALL have steadily improved over the last five decades, most recently due to impressive activity of chimeric antigen receptor modified T (CAR-T) cells an…

Primary and secondary pseudo-stability and progression after atezolizumab with and without bevacizumab

Background
Atypical tumor response patterns associated with immunotherapies pose significant challenges for assessing treatment response and clinical decision-making. We characterized the epidemiology, clinical impact, and molecular determinants of ps…

CD300ld blockade overcomes PMN-MDSC-mediated vaccine resistance in advanced tumors

Background
While cancer vaccines have demonstrated promising clinical potential, their therapeutic efficacy against advanced tumors remains suboptimal, highlighting the critical need to elucidate resistance mechanisms and develop targeted solutions. W…

Biomarkers of activity from a phase I study of cergutuzumab amunaleukin in patients with advanced solid tumors

Background
Cergutuzumab amunaleukin (CA) is an immunocytokine comprising an anticarcinoembryonic antigen (CEA) linked to an interleukin-2 (IL-2) variant. CA does not bind to CD25 (IL-2 receptor α) and was designed to maintain the T and natural k…

Therapeutic vaccination for glioblastoma elicited by retargeted oncolytic herpes virus

Background
Glioblastoma is an aggressive tumor with poor prognosis and limited treatment options due to its resistance to chemotherapy and radiotherapy, high heterogeneity, and ability to evade the immune system. Nevertheless, immunotherapy and oncoly…
