Mefloquine enhances the efficacy of anti-PD-1 immunotherapy via IFN-{gamma}-STAT1-IRF1-LPCAT3-induced ferroptosis in tumors

Background
Ferroptosis plays an important role in enhancing the efficacy of anti-programmed cell death 1 (PD-1) immunotherapy; however, the molecular mechanisms by which tumor ferroptosis sensitizes melanoma and lung cancer to anti-PD-1 immunotherapy …

High response rate with extended dosing of cemiplimab in advanced cutaneous squamous cell carcinoma

Background
Cemiplimab (Libtayo®), a human monoclonal immunoglobulin G4 antibody to the programmed cell death-1 receptor, is approved for the treatment of patients with advanced cutaneous squamous cell carcinoma (CSCC), who are not candidates for c…

Novel peptide-based oncolytic vaccine for enhancement of adaptive antitumor immune response via co-engagement of innate Fc{gamma} and Fc{alpha} receptors

Background
Cancer immunotherapy relies on using the immune system to recognize and eradicate cancer cells. Adaptive immunity, which consists of mainly antigen-specific cytotoxic T cells, plays a pivotal role in controlling cancer progression. However,…

Associations of concomitant medications with immune-related adverse events and survival in advanced cancers treated with immune checkpoint inhibitors: a comprehensive pan-cancer analysis

Background
While concomitant medications can affect the efficacy of immune checkpoint inhibitors (ICIs), few studies have assessed associations of concomitant medications with the occurrence and profile of immune-related adverse events (irAEs).

Metho…

Mucosal tumor vaccination delivering endogenous tumor antigens protects against pulmonary breast cancer metastases

Background
Generally, early-stage breast cancer has a good prognosis. However, if it spreads systemically, especially with pulmonary involvement, prospects worsen dramatically. Importantly, tumor-infiltrating T cells contribute to tumor control, parti…

An oncolytic vaccinia virus encoding hyaluronidase reshapes the extracellular matrix to enhance cancer chemotherapy and immunotherapy

Background
The redundant extracellular matrix (ECM) within tumor microenvironment (TME) such as hyaluronic acid (HA) often impairs intratumoral dissemination of antitumor drugs. Oncolytic viruses (OVs) are being studied extensively for cancer therapy …

Neoadjuvant chemoradiotherapy combined with sequential perioperative toripalimab in locally advanced esophageal squamous cell cancer

Background
Programmed death 1 (PD-1) inhibitor demonstrated durable antitumor activity in advanced esophageal squamous cell carcinoma (ESCC), but the clinical benefit of perioperative immunotherapy in ESCC remains unclear. This study evaluated the eff…

Network-based screening identifies sitagliptin as an antitumor drug targeting dendritic cells

Background
Dendritic cell (DC)-mediated antigen presentation is essential for the priming and activation of tumor-specific T cells. However, few drugs that specifically manipulate DC functions are available. The identification of drugs targeting DC ho…

Hybrid epithelial-mesenchymal status of lung cancer dictates metastatic success through differential interaction with NK cells

Background
Epithelial to mesenchymal transition (EMT) endows cancer cells with pro-metastatic properties, which appear most effective when cells enter an intermediate hybrid (H) state, characterized by integrated mesenchymal (M) and epithelial (E) tra…

Final results of urelumab, an anti-CD137 agonist monoclonal antibody, in combination with cetuximab or nivolumab in patients with advanced solid tumors

Background
Resistance to immune checkpoint inhibitors and targeted treatments for cancer is common; thus, novel immunotherapy agents are needed. Urelumab is a monoclonal antibody agonist that binds to CD137 receptors expressed on T cells. Here, we rep…
