How cell receptors control blood-vessel inflammation

Cell signaling by G protein-coupled receptors

NIH-funded research University of California, San Diego · NIH-11522501

This work looks at how certain cell receptors keep signaling from inside cells and how that can cause inflammation in blood vessels for people with vascular conditions.

What this research studies

The team at UC San Diego studies G protein-coupled receptors (GPCRs), common cell receptors that can keep sending signals after they are taken into the cell. They will identify how adding or removing a small tag called ubiquitin controls a key inflammatory pathway (p38 MAPK) and how the regulator ARRDC3 acts on endosomes. The lab uses molecular and cell-based experiments and likely animal models to find the proteins and steps that drive vascular inflammation. Learning these steps may point to new targets for drugs that reduce harmful inflammation in blood vessels.

Who could benefit from this research

Good fit: People with vascular inflammatory conditions such as atherosclerosis, vasculitis, or other cardiovascular diseases would be the most relevant group for future studies arising from this work.

Not a fit: People seeking immediate treatment or those without vascular inflammation are unlikely to receive direct benefit from this basic laboratory research.

Why it matters

Potential benefit: If successful, this work could reveal new drug targets to prevent or reduce blood-vessel inflammation that contributes to heart attack, stroke, and other vascular diseases.

How similar studies have performed: Prior lab studies have shown GPCRs can signal from endosomes and link to inflammation, but turning those findings into new therapies is still early and largely untested.
