How a natural skin peptide helps protect against infections

Cathelicidin in Skin Immunity

NIH-funded research University of California, San Diego · NIH-11261223

This project looks at whether boosting a natural skin protein called cathelicidin helps people’s skin fight bacterial infections.

What this research studies

You would hear about how cathelicidin, a protein made in the skin, helps kill bacteria and control inflammation. Researchers will study how cathelicidin works in skin cells and tissues, test factors that raise or lower its levels, and explore approaches that might increase its protective action. Work may include lab experiments with skin samples, molecular tests, and collaborations with clinics to link laboratory findings to human skin conditions. The team aims to find ways to strengthen the skin’s own defenses against bacteria.

Who could benefit from this research

Good fit: People with recurrent bacterial skin infections, chronic nonhealing wounds, or other skin conditions linked to weak skin immunity would be the most relevant candidates.

Not a fit: People with infections that do not involve the skin or with conditions unrelated to skin immunity are unlikely to see direct benefit from this research.

Why it matters

Potential benefit: If successful, this work could lead to treatments that boost natural skin defenses to prevent or treat bacterial skin infections.

How similar studies have performed: Previous studies show cathelicidin can kill bacteria and be increased by certain compounds, but turning that knowledge into proven patient treatments is still early.
