ABSTRACT
Peroxisome proliferator-activated receptors (PPAR) are transcription factors activated by ligands that belong to the superfamily of nuclear hormone receptors. There are three distinct subtypes, PPARα, PPARβ/δ, PPARγ. It has been shown that all subtypes participate in the regulation of several genes involved in the metabolism of glucose, lipids and more recently in cutaneous homeostasis.
Objectives: This document has been developed to provide an update on the biological functions of PPARs and how they influence the pathogenesis of various dermatological pathologies.
Methodology: Literature review was carried out.
Results: The expression of PPARs in the skin is an indisputable fact, the three subtypes are expressed in physiological conditions, in epidermis, dermis, sebaceous gland, hair follicle, as well as in human melanocytes and immature human Langerhans cells. Its activation produces variable effects on the skin, including the prodifferential, antiproliferative and immunomodulatory functions.
Conclusion: The PPARs are object of multiple investigations related to cutaneous pathology, presenting as interesting therapeutic targets in diseases such as acne, rosacea, psoriasis, atopic dermatitis, scarring alopecias, neoplasias (melanoma, squamous cell carcinoma, vascular tumors) and other diverse disorders.
