Blood-vessel gateway cells that guide immune cells into lymph nodes
Progenitor Cells for High Endothelium in the Immune Response
This project looks at how special blood-vessel cells form and change to let immune cells enter lymph nodes during inflammation, which matters for people with autoimmune disease and atherosclerosis.

What this research studies
From a patient viewpoint, researchers are mapping the different blood vessel cell types in lymph nodes and tracing capillary progenitor cells that become the specialized “high” endothelial venules (HEV) that allow immune cells through. They will use molecular atlases, cell-level profiling, imaging, and laboratory experiments to find the pathways that control progenitor behavior, HEV shape and metabolism, and the fate decision toward lymphocyte-recruiting HEV. The team will manipulate candidate pathways in experimental systems to see which changes block or promote HEV formation and function. Findings aim to link detailed cell maps to the molecular switches that drive inflammatory blood-vessel changes.
Who could benefit from this research
Good fit: People with autoimmune conditions or chronic inflammatory diseases, including those with atherosclerotic cardiovascular disease, would be the most relevant candidates for sample donation or for future therapies informed by this research.
Not a fit: Patients with conditions unrelated to immune-driven inflammation or those needing immediate clinical treatment are unlikely to see direct benefit from this basic science project right away.
Why it matters
Potential benefit: If successful, this work could point to new ways to limit harmful immune cell entry in autoimmune diseases or chronic inflammation and possibly reduce inflammation-linked complications in atherosclerosis.
How similar studies have performed: Prior research has described HEV expansion and generated cell atlases, but the specific molecular pathways controlling progenitor-to-HEV conversion targeted here remain largely untested and are a novel focus.
