Jan 31, 2025 by News Staff

Itch is a dominant symptom in dermatitis (eczema), and scratching promotes cutaneous inflammation, thereby worsening disease. However, the mechanisms through...

Sakamaki-Ching et al. demonstrated that acute dermal exposure to thirdhand smoke mimics the harmful effects of cigarette smoking, alters the human plasma proteome, initiates mechanisms of skin inflammatory disease, and elevates urinary biomarkers of oxidative harm. Image credit: Tumisu.
