Peroxisomes in dermatology. Part I.

Area of Science:

• Cell Biology
• Molecular Biology
• Dermatology

Background:

• Peroxisomes, once overlooked, are now recognized for crucial roles in cellular proliferation, differentiation, and metabolism.
• They influence lipid metabolism, insulin sensitivity, oxidative stress, aging, and tumorigenesis.
• Peroxisomal disorders have significant, though often underestimated, cellular impacts.

Purpose of the Study:

• To review genetic peroxisomal disorders, focusing on skin manifestations and underlying genetic defects.
• To explore emerging knowledge of peroxisomal proliferator activator receptors (PPARs) and their function modulation.
• To discuss how PPAR discovery has led to new therapeutic strategies targeting peroxisomal function.

Main Methods:

• Literature review of genetically determined peroxisomal disorders.
• Analysis of recent research on genetic defects in peroxisomal function.
• Examination of the role of PPARs and their ligands in modulating peroxisomal activity.

Main Results:

• Genetic defects lead to various peroxisomal disorders, some with pronounced skin symptoms.
• PPARs and their ligands demonstrate significant influence over peroxisomal functions.
• Ligand-activated PPARs represent a new class of drugs for modulating peroxisomal activity.

Conclusions:

• PPAR modulation in skin shows promise for treating inflammatory skin conditions like acne vulgaris.
• Potential applications include managing skin aging, barrier dysfunction, and impaired wound healing.
• PPAR ligands may also mitigate adverse effects from metabolic dysregulation caused by other drugs.
