- (PT) exhibits diverse biological activities, including anti‑inflammatory and antioxidant effects; however, its potential effects on atopic dermatitis (AD) are unclear. The present study examined the effects of PT flower absolute (PTFAb) on AD‑related responses, particularly mast cell activation and keratinocyte barrier‑related responses. PTFAb was isolated from PT flowers using a solvent extraction method and its chemical composition was analyzed by gas chromatography/mass spectrometry, through which 13 components were identified. biological tests on rat basophilic leukemia cells (RBL‑2H3 cells; a commonly used mast cell model) and human epidermal keratinocytes (HaCaT cells) were performed using water‑soluble tetrazolium salt, 5‑bromo‑2'‑deoxyuridine incorporation, Boyden chamber, immunoblotting and enzyme‑linked immunosorbent assay methods. All experiments were conducted on cells at nontoxic PTFAb concentrations. PTFAb reduced the expression of the v‑soluble N‑ethylmaleimide‑sensitive factor attachment protein receptor proteins vesicle‑associated membrane protein (VAMP)7 and VAMP8 in RBL‑2H3 cells. In RBL‑2H3 cells stimulated with anti‑dinitrophenyl (DNP)‑immunoglobulin E and DNP‑bovine serum albumin, PTFAb suppressed the release of β‑hexosaminidase and histamine (indicators of mast cell degranulation), and the phosphorylation of spleen tyrosine kinase, phosphatidylinositol 3‑kinase and protein kinase B. PTFAb also induced proliferation, migration, and type Ⅰ and Ⅳ collagen synthesis. Furthermore, PTFAb upregulated tumor necrosis factor‑α (TNF‑α)‑reduced filaggrin expression and the expression of hyaluronan synthase (HAS)‑2 and HAS‑3 in HaCaT cells, and reduced TNF‑α‑increased intercellular adhesion molecule‑1 expression in HaCaT cells. In conclusion, PTFAb may exert inhibitory effects on mast cell degranulation‑related responses and potentiate skin barrier‑related responses, suggesting its potential to modulate AD‑related cellular responses or skin barrier function. - Source: PubMed

Yoo Da YeonWon Kyung JongKim Do YoonKim Yoon YiBae Ji HyeYun Ji SeongLee Hwan Myung - Hyaluronan (HA) is a major glycosaminoglycan of the extracellular matrix that regulates cell migration, signaling, and tissue homeostasis. Its turnover is controlled by coordinated synthesis by HA synthases and degradation by hyaluronidases. Among these hyaluronidases, TMEM2, the only known transmembrane hyaluronidase, plays a unique role in HA degradation at the cell surface; however, the cellular conditions that support its activity remain incompletely understood. To address this, we developed a cell-based HA turnover assay to examine TMEM2-mediated degradation of endogenously synthesized HA, rather than exogenously added, fluorescently labeled HA used in previous studies. Using this system, we show that TMEM2 readily degrades high-molecular weight HA synthesized by co-expressed HAS3. This degradation occurs only when TMEM2 and HAS3 are co-expressed in the same cells (), whereas co-culture of TMEM2-expressing cells with HAS3-expressing cells supports little or no degradation. Interestingly, HA-binding cell surface receptors CD44 and its homolog LYVE-1 promote efficient TMEM2-mediated HA degradation even under conditions, whereas other HA-binding proteins, including TSG-6, layilin, TLR2, RHAMM, and ICAM-1, do not. These findings suggest a spatially regulated mechanism of TMEM2 activity in which capture of HA at the cell surface, mediated by CD44 or LYVE-1, contributes to efficient HA degradation by TMEM2. - Source: PubMed

Tobisawa YukiYano FumiakiraTomioka-Inagawa RisaIrie FumitoshiKoie TakuyaYamaguchi Yu - The growing demand for safe, naturally derived active ingredients in cosmetic and dermatological formulations has accelerated interest in green nanomaterials with multifunctional skin-protective properties. This study presents the microwave-assisted synthesis and comparative evaluation of carbon dots (CDs) derived from hyaluronic acid (HA) and eastern prickly pear cactus (Opuntia humifusa (O. humifusa)) for their moisturizing and antioxidant properties. Both CDs exhibited strong UV absorption at 264 nm and characteristic blue photoluminescence around 450 nm, indicating their potential as UV-protective cosmetic nanomaterials. In antioxidant assays, O. humifusa-CD exhibited significantly higher radical scavenging activity (p < 0.05), with an estimated ABTS IC₅₀ value of 585 µg/mL compared with 710 µg/mL for HA-CD. Similarly, both CDs showed significant intracellular ROS scavenging activity in HO-stimulated HaCaT cells, achieving close to 88% and 77% ROS inhibition at 500 µg/mL after 24 h and 48 h, respectively. Moisturizing activity was evaluated at the molecular level through western blot analysis. HA-CDs significantly upregulated the expression of AQP3, HAS-2, and HAS-3 by approximately 1.77-, 2.05-, and 2.24-fold, respectively. On the other hand, O. humifusa-CDs exhibited significantly greater anti-inflammatory activity (p < 0.05), reducing NO production by approximately 74% in LPS-stimulated RAW 264.7 macrophages. These findings highlight the multifunctional potential of HA-CDs and O. humifusa-CDs as natural and biocompatible materials, making them suitable for incorporation into advanced topical formulations for skincare. Although the present findings demonstrate the promising antioxidant, moisturizing, and anti-inflammatory potential of the synthesized CDs in vitro, further in vivo studies and clinical evaluations are necessary to confirm their safety and effectiveness for practical cosmetic applications. - Source: PubMed

Youn Jeong-YunJaison AugustineChoi Hyeon SeokNgoc Le Thi NhuMoon Ju-YoungJeong SugyeongLee Young-Chul - Hyaluronan (HA) is a key component of the pericellular and extracellular matrix and is synthesized by both non-hematopoietic and myeloid cells. In this study, we demonstrate that adaptive immune T cells not only respond to exogenously added high-molecular-weight HA by reducing proliferation but also generate an endogenous HA-rich glycocalyx in a stage-specific manner, as shown by fluorescence assisted carbohydrate electrophoresis and imaging studies. HA in the glycocalyx of naive CD4 T cells, localized with the HA-binding proteoglycan, versican (VCAN). During differentiation into effector subsets, pericellular HA/VCAN is removed, with HA detected intracellularly, often co-localized with CD44. Hyaluronan synthase 3 (HAS3) is the predominant enzyme in naive CD4 T cells, as HAS3-deficient T cells display minimal surface HA and exhibit extensive proliferation. We discuss the significance of the metabolic turnover of the HA/VCAN glycocalyx in T cells as a mechanism to regulate activation and proliferation. - Source: PubMed

Existing VF models use monocultures that lack the stratified epithelium, lamina propria, and physiological perfusion. We developed a chip-based co-culture model of human VF mucosa and applied it to acute PM exposure. - Source: PubMed
