Recent advances on endogenous gasotransmitters in inflammatory dermatological disorders.

[Display omitted] • Endogenous gasotransmitters nitric oxide (NO), carbon monoxide (CO), hydrogen sulfide (H 2 S), and potential candidates sulfur dioxide (SO 2), methane (CH 4), hydrogen gas (H 2), ammonia (NH 3) and carbon dioxide (CO 2), are generated within the human body. • Endogenous and potential gasotransmitters regulate inflammation, vasodilation, and oxidation in inflammatory dermatological disorders. • Endogenous and potential gasotransmitters play potential roles in psoriasis, atopic dermatitis, acne, and chronic skin ulcers. • Further research should explore the function of these gases and gas donors and inhibitors in inflammatory dermatological disorders. Endogenous gasotransmitters are small gaseous mediators that can be generated endogenously by mammalian organisms. The dysregulation of the gasotransmitter system is associated with numerous disorders ranging from inflammatory diseases to cancers. However, the relevance of these endogenous gasotransmitters, prodrug donors and inhibitors in inflammatory dermatological disorders has not yet been thoroughly reviewed and discussed. This review discusses the recent progress and will provide perspectives on endogenous gasotransmitters in the context of inflammatory dermatological disorders. Endogenous gasotransmitters nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H 2 S) are signaling molecules that regulate several physiological and pathological processes. In addition, sulfur dioxide (SO₂), methane (CH 4), hydrogen gas (H 2), ammonia (NH 3), and carbon dioxide (CO 2) can also be generated endogenously and may take part in physiological and pathological processes. These signaling molecules regulate inflammation, vasodilation, and oxidative stress, offering therapeutic potential and attracting interest in the field of inflammatory dermatological disorders including psoriasis, atopic dermatitis, acne, rosacea, and chronic skin ulcers. The development of effective gas donors and inhibitors is a promising alternative to treat inflammatory dermatological disorders with controllable and precise delivery in the future.
