Hypothesis

PGRPs play a role in the development of atopic dermatitis and contact dermatitis.

Conclusion

Pglyrp3 and Pglyrp4 protect against severe atopic dermatitis by promoting Treg cell accumulation and inhibiting Th17 cell activation.

Supporting Evidence

  • Pglyrp3 and Pglyrp4 deficient mice showed increased sensitivity to atopic dermatitis.
  • Reduced recruitment of Treg cells and increased Th17 cell activation were observed in Pglyrp3 and Pglyrp4 deficient mice.
  • Vitamin D treatment increased Treg cells and reduced inflammation in Pglyrp3 deficient mice.

Takeaway

Some proteins in our skin help keep it healthy by stopping too much inflammation when we have skin allergies.

Methodology

The study used Pglyrp-deficient mice and mouse models of chemically-induced atopic dermatitis and contact dermatitis.
