One Blood-Vessel Cell Guides T Cells Into Metastases
LPL-producing endothelial cells act as entry guides for activated immune cells in liver metastases.
Summary
LPL-producing endothelial cells act as entry guides for activated immune cells in liver metastases.
A DKFZ and Heidelberg University team identified a specialized endothelial-cell subgroup inside liver metastases that produces lipoprotein lipase. These cells help activated T cells cross tumor blood vessels and enter metastatic tissue, connecting vascular metabolism to immune access. The finding may help explain why some tumors respond poorly to immunotherapy and suggests a route for improving infiltration. It remains mechanistic research, not a validated therapy for patients with liver metastases.
