Activating innate immune responses repolarizes hPSC-derived CAR macrophages to improve anti-tumor activity

Shen, Lyu, Xu, et al. developed a culture system for macrophage differentiation from human pluripotent stem cells (hPSC) to manufacture CAR macrophages. The generated hPSC-CAR-M had a pro-inflammatory...

Neoadjuvant nivolumab with or without relatlimab in resectable non-small-cell lung cancer: a randomized phase 2 trial

Schuler et al. reported the safety and feasibility of two preoperative doses of nivolumab or nivolumab plus relatlimab without delaying curatively intended surgery in patients with resectable NSCLC. B...

The immunoglobulin superfamily ligand B7H6 subjects T cell responses to NK cell surveillance

Kilian, Friedrich, and Lu et al. showed that activated human T cells (primarily CD8+ TEFF cells, but also granzyme A+ CD4+ TEM cells) and CD19-CAR T cells expressed high cell surface levels of and did...

HPN328, a Trispecific T Cell-activating Protein Construct Targeting DLL3-Expressing Solid Tumors

Molloy et al. engineered HPN328, a trispecific DLL3-targeting T cell engager with extended half-life via serum albumin binding. HPN328 induced a potent dose-dependent killing of DLL3-expressing SCLC l...

PGE(2) sabotages TIL expansion and effector differentiation

May 8, 2024

The bioactive lipid prostaglandin E2 (PGE2) is often detected in the tumor microenvironment (TME), and has been shown to play a role in immune escape and cancer progression. Two recent studies published in Nature assessed the effects of PGE...

Targeting IL-2 to CD8+ T cells enhances its benefits while reducing its risks

May 1, 2024

IL-2 is one of the earliest immunotherapeutic agents to induce complete responses in patients with cancer, but its use has been limited by its toxicity and the need for frequent administration. In order to capitalize on the desirable effects...

Personalized neoantigen vaccine improves anti-PD-1 in advanced hepatocellular carcinoma in early clinical trial

April 24, 2024

Advanced hepatocellular carcinoma (HCC) is a tumor type with a modest tumor mutation burden (TMB), low T cell infiltration, limited responses to checkpoint inhibitors, and a low patient survival rate. To overcome these hurdles, Yarchoan et al. conducted a...
