How cell receptors inside cells drive blood vessel inflammation

Cell signaling by G protein-coupled receptors

NIH-funded research University of California, San Diego · NIH-11307154

Researchers are looking at whether signals from certain cell receptors that keep working inside cells cause inflammation in blood vessels and could affect people with vascular disease.

What this research studies

You can think of this work as scientists tracing how G protein-coupled receptors (GPCRs) keep sending signals after they are pulled into the cell and how those signals trigger inflammation in blood vessels. The lab will focus on how adding or removing ubiquitin tags controls GPCR-triggered p38 signaling from endosomes and how two specific deubiquitinase enzymes act in this process. They will use cellular experiments and animal models to find the key protein targets and to test how changing these steps affects vascular inflammation. Findings aim to clarify the molecular steps that might be targeted by future drugs to reduce harmful blood vessel inflammation.

Who could benefit from this research

Good fit: People with vascular inflammatory conditions or at higher risk for cardiovascular disease would be the most relevant patient group for future therapies arising from this work.

Not a fit: People without blood-vessel or cardiovascular inflammation or those with unrelated conditions are unlikely to benefit directly from this basic laboratory research.

Why it matters

Potential benefit: If successful, this work could point to new drug targets that reduce vascular inflammation and related cardiovascular disease.

How similar studies have performed: Prior studies have shown that GPCRs can signal from inside cells and that ubiquitination affects signaling, but turning these findings into therapies is still at an early stage.
