The PI3K-Akt-mTOR and Associated Signaling Pathways as Molecular Drivers of Immune-Mediated Inflammatory Skin Diseases: Update on Therapeutic Strategy Using Natural and Synthetic Compounds. Cells 2023; 12:1671. [PMID: 37371141 PMCID: PMC10297376 DOI: 10.3390/cells12121671] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 06/10/2023] [Accepted: 06/12/2023] [Indexed: 06/29/2023] Open
Abstract
The dysregulated phosphatidylinositol-3-kinase (PI3K)-Akt-mammalian target of rapamycin (mTOR) signaling pathway has been implicated in various immune-mediated inflammatory and hyperproliferative dermatoses such as acne, atopic dermatitis, alopecia, psoriasis, wounds, and vitiligo, and is associated with poor treatment outcomes. Improved comprehension of the consequences of the dysregulated PI3K/Akt/mTOR pathway in patients with inflammatory dermatoses has resulted in the development of novel therapeutic approaches. Nonetheless, more studies are necessary to validate the regulatory role of this pathway and to create more effective preventive and treatment methods for a wide range of inflammatory skin diseases. Several studies have revealed that certain natural products and synthetic compounds can obstruct the expression/activity of PI3K/Akt/mTOR, underscoring their potential in managing common and persistent skin inflammatory disorders. This review summarizes recent advances in understanding the role of the activated PI3K/Akt/mTOR pathway and associated components in immune-mediated inflammatory dermatoses and discusses the potential of bioactive natural products, synthetic scaffolds, and biologic agents in their prevention and treatment. However, further research is necessary to validate the regulatory role of this pathway and develop more effective therapies for inflammatory skin disorders.

Abstract
Atopic dermatitis (AD) is a dermatological disease accompanied by dry and cracked skin with severe pruritus. Although various therapeutic strategies have been introduced to alleviate AD, it remains challenging to cure the disorder. To achieve such a goal, understanding the pathophysiological mechanisms of AD is a prerequisite, requiring mouse models that properly reflect the AD phenotypes. Currently, numerous AD mouse models have been established, but each model has its own advantages and weaknesses. In this review, we categorized and summarized mouse models of AD and described their characteristics from a researcher's perspective.

Cytokines and chemokines modulation of itch. Neuroscience 2022; 495:74-85.

Abstract
Itch (pruritus) is a common cutaneous symptom widely associated with many skin complaints, and chronic itch can be a severe clinical problem. The onset and perpetuation of itch are linked to cytokines, such as interleukin (IL)-31, IL-4, IL-13, IL-33, thymic stromal lymphopoietin, and tumor necrosis factor-alpha, and chemokines, such as chemokine (C-C motif) ligand 2 and C-X-C motif chemokine ligand 10. This review highlights research that has attempted to determine the attributes of various cytokines and chemokines concerning the development and modulation of itch. Through such research, clinical approaches targeting cytokines and/or chemokines may arise, which may further the development of itch therapeutics.

Abstract
Atopic dermatitis (AD) is characterized by progressive skin inflammation. In addition, sulforaphane is an isothiocyanate organosulfur compound from cruciferous vegetables. Sulforaphane was reported to ameliorate inflammatory responses. Therefore, this study was conducted to evaluate the protective effects of sulforaphane in AD through affecting the balance between pro-inflammatory and anti-inflammatory cytokines and to evaluate its effect on AD-induced activation of the apoptotic pathway. The method of repeated rubbing of 2,4-dinitrochlorobenzene (DNCB) on shaved dorsal skin and ears of mice was used for induction of AD. After the development of AD, part of the mice was injected with 1 mg/kg sulforaphane, subcutaneously three times weekly. Samples of skin were isolated for assessment of gene and protein expression of 8-hydroxy2'-deoxyguanosine, IgE, NFκB, TNF-α, IL-1β, IL-4, IL-10, Nrf2, and caspase-3. In addition, skin sections from different groups were stained with anti-caspase-3 antibodies. Mice in the AD group were characterized by increased gene and protein expression of 8-hydroxy2'-deoxyguanosine, IgE, NFκB, TNF-α, IL-1β, and caspase-3 associated with reduced expression of Nrf2, IL-4, and IL-10. Treatment of AD mice with sulforaphane significantly reduced the number of scratches, dermatitis score, and ear thickness. In addition, sulforaphane significantly attenuated the gene and protein expressions produced by AD. Therefore, sulforaphane alleviated AD induced in mice through inhibition of oxidative stress, oxidative DNA damage, inflammation, and apoptosis. HIGHLIGHTSAtopic dermatitis is a chronic relapsing inflammatory disease.Sulforaphane is an isothiocyanate organosulfur compound obtained from cruciferous vegetables.Sulforaphane alleviated AD induced in mice.Sulforaphane inhibits oxidative stress, oxidative DNA damage, inflammation, and apoptosis.
