Trehalose Prevents IL-4/IL-13-Induced Skin Barrier Impairment by Suppressing IL-33 Expression and Increasing NRF2 Activation in Human Keratinocytes In Vitro. J Invest Dermatol 2025; 145:1422-1432.e10.

Abstract
Skin barrier dysfunction initiates or deteriorates various cutaneous problems, such as atopic dermatitis. At high concentrations, the nonreducing disaccharide trehalose (α-d-glucopyranosyl α-d-glucopyranoside) induces a transient senescence-like state in fibroblasts and promotes wound repair. In this study, we investigated the effect of trehalose on normal human keratinocytes and demonstrated its specific role in the skin barrier. RNA-sequencing analysis revealed that trehalose regulates the expression of many skin barrier-associated genes. T helper 2 cytokines IL-4/IL-13 were observed to downregulate several differentiation markers (FLG, loricrin, keratin 1, and keratin 10) and epidermal antimicrobial proteins in monolayer-cultured keratinocytes and living skin equivalents and impaired skin barrier function in living skin equivalents, all of which were significantly upregulated or restored by trehalose. Trehalose inhibited IL-33 expression and reduced nuclear IL-33 levels by activating MAPK/extracellular signal-regulated kinase kinase 5-extracellular signal-regulated kinase 5 and suppressing extracellular signal-regulated kinase kinase 1/2-extracellular signal-regulated kinase pathway. It also increased NRF2 activation to trigger antioxidant enzyme production through JNK, thus neutralizing IL-4/IL-13-mediated oxidative stress. Trehalose prevented IL-4/IL-13-mediated signal transducer and activator of transcription 3/signal transducer and activator of transcription 6 activation and restored IL-4/IL-13-suppressed skin barrier molecules through IL-33 downregulation and NRF2 activation. This study demonstrated that trehalose may play a role in skin barrier repair in atopic dermatitis.

Abstract
Autophagy is a cellular recycling system that, through the sequestration and degradation of intracellular components regulates multiple cellular functions to maintain cellular homeostasis and survival. Dysregulation of autophagy is closely associated with the development of physiological alterations and human diseases, including the loss of regenerative capacity. Tissue regeneration is a highly complex process that relies on the coordinated interplay of several cellular processes, such as injury sensing, defense responses, cell proliferation, differentiation, migration, and cellular senescence. These processes act synergistically to repair or replace damaged tissues and restore their morphology and function. In this review, we examine the evidence supporting the involvement of the autophagy pathway in the different cellular mechanisms comprising the processes of regeneration and repair across different regenerative contexts. Additionally, we explore how modulating autophagy can enhance or accelerate regeneration and repair, highlighting autophagy as a promising therapeutic target in regenerative medicine for the development of autophagy-based treatments for human diseases.

Endocytosis-mediated healing: recombinant human collagen type III chain-induced wound healing for scar-free recovery. Regen Biomater 2025; 12:rbae149. [PMID: 40124986 PMCID: PMC11930350 DOI: 10.1093/rb/rbae149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2024] [Revised: 11/03/2024] [Accepted: 11/17/2024] [Indexed: 03/25/2025] Open
Abstract
Scar formation can be effectively prevented when the proportion of collagen type I (Col I)/type III (Col III) is reduced. Unlike Col III, recombinant human collagen type III chain (RHC III chain) does not possess a triple helical structure. This study aimed to elucidate the capacity of fibroblasts to uptake RHC III chain, reduce the Col I/Col III ratio and determine its effects on wound healing and scar. RHC III chain demonstrates qualified cell compatibility. In cell experiments, immunofluorescence and western blot (WB) analyses revealed an increase in the polyhistidine tag level, indicating that RHC III chain in internalized by these cells. Transmission electron microscopy showed increased intracellular phagocytic activity, indicating that RHC III chain enters fibroblasts by endocytosis. The immunofluorescence and WB showed that Col III synthesis enhanced, and Col I/Col III ratio reduced. However, the polyhistidine tag disappeared with time, indicating that RHC III chain degraded within cells and then synthesized into Col III. The content of newly synthesized Col III increases, but real-time fluorescence quantitative showed a decrease in Col III related gene content suggests the formation of negative feedback. However, due to the sufficient raw materials, the amount of Col III synthesis is still increasing, leading to the reduction of the ratio of type I collagen/type III collagen, which beneficial to wound healing and reduce scar hyperplasia. In animal experiments, the SD rat full-thickness skin defect model of wound suggests that RHC III chain also takes effect through endocytosis and ultimately promotes wound healing. The rabbit ear scar model suggests that RHC III chain inhibits scar proliferation by reducing the ratio of Col I/Col III. In summary, RHC III chain was endocytosed by fibroblasts to promote native Col III synthesis, as well as promote wound healing and reduce scar hyperplasia.

JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY. B, BIOLOGY 2024; 257:112948.

Abstract
Autophagy participates in the regulation of ferroptosis. Among numerous autophagy-related genes (ATGs), ATG5 plays a pivotal role in ferroptosis. However, how ATG5-mediated ferroptosis functions in UVB-induced skin inflammation is still unclear. In this study, we unveil that the core ferroptosis inhibitor GPX4 is significantly decreased in human skin tissue exposed to sunlight. We report that ATG5 deletion in mouse keratinocytes strongly protects against UVB-induced keratinocyte ferroptosis and skin inflammation. Mechanistically, ATG5 promotes the autophagy-dependent degradation of GPX4 in UVB-exposed keratinocytes, which leads to UVB-induced keratinocyte ferroptosis. Furthermore, we find that IFN-γ secreted by ferroptotic keratinocytes facilitates the M1 polarization of macrophages, which results in the exacerbation of UVB-induced skin inflammation. Together, our data indicate that ATG5 exacerbates UVB-induced keratinocyte ferroptosis in the epidermis, which subsequently gives rise to the secretion of IFN-γ and M1 polarization. Our study provides novel evidence that targeting ATG5 may serve as a potential therapeutic strategy for the amelioration of UVB-caused skin damage.

Abstract
The study aimed to perform a comprehensive in vitro and in vivo evaluation of a newly developed, patent-pending, powder-to-hydrogel, film-forming polymer complex base, which possesses tissue-protective and microbiome-supportive properties, and to compare its characteristics with poloxamer 407. The study used a combination of in vitro assays, including tissue viability and cell migration, and in vivo wound healing evaluations in male diabetic mice. Microbiome dynamics at wound sites were also analyzed. The in vitro assays demonstrated that the polymer complex base was non-cytotoxic and that it enhanced cell migration over poloxamer 407. In vivo, the polymer complex base demonstrated superior wound healing capabilities, particularly in combination with misoprostol and phenytoin, as evidenced by the reduced wound area and inflammation scores. Microbiome analysis revealed favorable shifts in bacterial populations associated with the polymer complex base-treated wounds. The polymer complex base demonstrates clinical significance in wound care, potentially offering improved healing, safety and microbiome support. Its transformative properties and efficacy in drug delivery make it a promising candidate for advanced wound care applications, particularly in chronic wound management.

Effect of tea polyphenol-trehalose complex coating solutions on physiological stress and flesh quality of marine-cultured Turbot Scophthalmus maximus during waterless transport. JOURNAL OF AQUATIC ANIMAL HEALTH 2024; 36:151-163.

Abstract
OBJECTIVE The waterless transport of live fish has changed the present situation of live-fish transport. However, the waterless transport environment may cause stress in fish. This research evaluated the effect of tea polyphenol-trehalose (TPT) coating solutions on Turbot Scophthalmus maximus during waterless transport. METHODS After cold acclimation, Turbot were coated and subsequently transported in a waterless environment for 18 h. Physiological and biochemical parameters were measured, including lysozyme (LZM) and immunoglobulin M (IgM) activities, serum creatinine (Cr) and uric acid (UA) concentrations, and nutritional flavor. RESULT The results showed that the nonspecific immunity of Turbot was inhibited during the waterless transport; the LZM activity first increased and then decreased, and the serum Cr and UA concentrations significantly increased. In addition, the waterless transport promoted the breakdown of Turbot flesh proteins, leading to changes in nucleotides and free amino acids (FAAs). After waterless transport, the LZM and IgM activities in the TPT-treated Turbot were higher than those in the control group (CK), and the changes in FAA content and nucleotides were smaller than those observed in the CK group. CONCLUSION This study shows that the use of TPT coating solution can reduce the impact of waterless transportation stress on the immune and metabolic functions of Turbot and can maintain the meat quality and flavor of Turbot.
