Turning tumor-helping immune cells into cancer-eating macrophages to fight glioblastoma

Macrophage-based Therapy and Immune Checkpoint Blockade for Glioblastoma

NIH-funded research Cleveland Clinic Lerner Com-Cwru · NIH-11238057

This project tries to convert tumor-supporting macrophages into cancer-eating macrophages and combine that change with checkpoint drugs to help people with glioblastoma.

What this research studies

Researchers use lab-grown (iPSC-derived) macrophages and fluorescently labeled glioma cells to screen for drugs that make macrophages engulf tumor cells. They discovered that certain BACE1 inhibitors boost macrophage phagocytosis of glioma cells, including glioma stem cells. The team will study how reprogrammed macrophages alter the tumor immune environment and whether pairing this approach with immune checkpoint blockade increases anti-tumor activity. Most work is currently done in the lab and could guide future clinical testing for patients with GBM.

Who could benefit from this research

Good fit: Adults with a diagnosis of glioblastoma, particularly those with recurrent or treatment-resistant disease, would be the most likely candidates for future trials informed by this work.

Not a fit: People with non-glioblastoma brain conditions, tumors that do not involve macrophage-driven suppression, or those unable to receive immune-modulating treatments may not benefit from this approach.

Why it matters

Potential benefit: If successful, this approach could improve immune therapy responses and help shrink or slow growth of glioblastoma tumors.

How similar studies have performed: Lab and animal studies of macrophage reprogramming and checkpoint blockade have shown promise, but effective patient treatments for glioblastoma remain largely unproven.
