EZH2 negatively regulates PD-L1 expression in hepatocellular carcinoma

Accumulating studies suggest that targeting epigenetic modifications could improve the efficacy of tumor immunotherapy; however, the mechanisms underlying this phenomenon remain largely unknown. Here, the authors investigated the ability of the epigenetic modifier, enhancer of zeste 2 polycomb...

Long-term survival without graft-versus-host-disease following infusion of allogeneic myeloma-specific Vβ T cell families

Despite chemo-induction therapy and autologous stem cell transplantation (ASCT), the vast majority of patients with Multiple Myeloma (MM) relapse within 7 years and the disease remains incurable. Adoptive Allogeneic T-cell therapy (ATCT) might be curative for MM, however current ATCT protocols...

Blood-derived dendritic cell vaccinations induce immune responses that correlate with clinical outcome in patients with chemo-naive castration-resistant prostate cancer

Clinical benefit of cellular immunotherapy has been shown in patients with castration-resistant prostate cancer (CRPC) . The authors investigated the immunological response and clinical outcome of vaccination with blood-derived CD1c + myeloid dendritic cells (mDCs; cDC2) and plasmacytoid...

CRISPR-Cas9 disruption of PD-1 enhances activity of universal EGFRvIII CAR T cells in a preclinical model of human glioblastoma

Despite remarkable success in the treatment of hematological malignancies, CAR T-cell therapies for solid tumors have floundered, in large part due to local immune suppression and the effects of prolonged stimulation leading to T-cell dysfunction and exhaustion. One mechanism by which gliomas...

Development and validation of an immune checkpoint-based signature to predict prognosis in nasopharyngeal carcinoma using computational pathology analysis

Immunotherapy, especially immune checkpoint inhibition, has provided powerful tools against cancer. The authors aimed to detect the expression of common immune checkpoints and evaluate their prognostic values in nasopharyngeal carcinoma (NPC). They concluded that the expression status of nine...

Distinct tumor microenvironments of lytic and blastic bone metastases in prostate cancer patients

The most common metastatic lesions of prostate cancer are in bone and can be classified into three distinct pathology subtypes: lytic, blastic, and an indeterminate mixture of both. The authors investigated a cohort of decalcified formalin-fixed and paraffin-embedded (FFPE) patient specimens...

Domatinostat favors the immunotherapy response by modulating the tumor immune microenvironment (TIME)

The efficacy of PD-(L)1 blockade depends on the composition of the tumor immune microenvironment (TIME) and is generally higher in tumors with pre-existing cytotoxic T cells (CTL) than in those with low CTL numbers. Nonetheless, a significant proportion of patients with pre-existing immunity...

Secondary resistance to immunotherapy associated with β-catenin pathway activation or PTEN loss in metastatic melanoma

While cancer immunotherapies including checkpoint blockade antibodies, adoptive T cell therapy, and even some vaccines have given rise to major clinical responses with durability in many cases, a subset of patients who initially respond subsequently develop secondary resistance to therapy. Tumor...

Targeting of CXCR3 improves anti-myeloma efficacy of adoptively transferred activated natural killer cells

The peculiar multiple myeloma microenvironment, characterized by up-regulated levels of several inflammatory chemokines, including the CXCR3 receptor ligands CXCL9 and CXCL10, limits NK cell positioning into the bone marrow by interfering with CXCR4 function. It is still unclear if the...
