GPR68 and sepsis-related lung injury

GPR68 as a novel modulator of septic lung injury

NIH-funded research University of Maryland Baltimore · NIH-11167616

What this research studies

This work looks at how a proton-sensing protein called GPR68 influences lung inflammation and blood-vessel leak during severe sepsis and ARDS. Scientists will use lab-grown cells and animal infection models to change GPR68 activity and watch effects on immune signals, fluid leak, and lung tissue damage. They will measure cytokines, immune cell infiltration, and lung barrier function to understand how GPR68 controls the injury process. The goal is to identify whether targeting GPR68 could point toward new treatments for sepsis-related respiratory failure.

Who could benefit from this research

Good fit: Adults with sepsis that began in the lungs or with a current diagnosis of ARDS — especially bacterial pneumonia or suspected MRSA-related cases — would be the most relevant candidates for related future studies.

Not a fit: People with non-infectious causes of lung injury, stable chronic lung disease without acute sepsis, or those far from the study site are unlikely to benefit directly from this grant right now.

Why it matters

Potential benefit: If successful, the project could point to new therapies that reduce inflammation and prevent or lessen breathing failure in sepsis-related ARDS.

How similar studies have performed: Basic research on proton-sensing receptors suggests they affect inflammation, but using GPR68 as a target for ARDS is relatively new and largely untested in humans.
