This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.
