Understanding Skin Barrier Differences
Skin Barrier Adaptation
This project explores how our skin's protective barrier and vitamin D production adapt to different environments, especially looking at differences between people of European and African descent.

What this research studies
Our skin's outer layer, the epidermis, protects us from the environment and makes vitamin D. When this layer doesn't work well, it can lead to skin infections and inflammation. We've found that a specific gene, involucrin (IVL), which is important for skin function, shows different activity levels in people of European and African ancestry, suggesting our skin has adapted over time. This research aims to understand how IVL affects vitamin D receptor function in the skin, which is crucial for skin health and immune responses. By studying these mechanisms, we hope to learn more about how skin adapts and functions differently across populations.
Who could benefit from this research
Good fit: This foundational research is relevant to anyone interested in skin health, especially individuals of European or African ancestry, as it explores genetic differences in skin function.
Not a fit: Patients seeking immediate new treatments or direct clinical interventions will not directly benefit from this basic science project.
Why it matters
Potential benefit: If successful, this work could lead to a better understanding of skin health disparities and new ways to address skin conditions, infections, and inflammation, particularly in diverse populations.
How similar studies have performed: This project builds on recent discoveries about human epidermal evolution and a newly identified role for involucrin in modulating vitamin D receptor signaling, representing an emerging paradigm.
