- Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by keratinocyte hyperproliferation, altered differentiation, barrier dysfunction, and oxidative stress. Currently available therapies, including monoclonal antibodies and JAK inhibitors, have improved AD management but do not address all aspects of the disease, supporting the investigation of natural-product strategies as complementary approaches to long-term care. An acute in vitro model of canine atopic-like inflammation was established by exposing canine progenitor epidermal keratinocytes (CPEK) for 24 h to a defined cytokine cocktail (IFN-γ, IL-4, IL-13), followed by 24 h of treatment with hemp oil, blackcurrant seed oil, vitamin D, or their combination. Proliferation (Ki-67, cell-cycle), differentiation (KRT5, KRT10, TGM1, involucrin), tight-junction organization (CLDN1, TJP1, ZO-1, TEER), wound closure, nitrosative stress (3-nitrotyrosine), the NRF2/BACH1/HMOX1 axis, and the secretion of STAT1- and NF-κB-dependent inflammatory mediators (CXCL9, CXCL10, IL-8, IL-6) and the STAT6-targeted chemokine CCL17 were assessed. The cytokine cocktail induced a coherent AD-like phenotype: increased Ki-67, downregulated CLDN1, sustained nitrosative stress, NRF2 elevation paralleled by BACH1 induction, and robust secretion of STAT1- and NF-κB-dependent mediators. The four treatments modulated this phenotype according to clearly differential, pathway-specific profiles. Vitamin D, alone or combined, emerged as the most effective modulator of proliferation and acted preferentially on the downstream redox arm, inducing HMOX1 and reducing BACH1; both vitamin D-containing formulations exerted broad anti-inflammatory activity across the STAT1 and NF-κB axes. Hemp oil acted preferentially on tight-junction integrity (CLDN1 recovery), on the upstream NRF2 arm (NFE2L2 induction), on the STAT1 chemokine arm (CXCL9, CXCL10 reduction), and on wound closure. Blackcurrant seed oil acted preferentially on NF-κB-dependent IL-8 and on early wound-closure dynamics. This differential pharmacological footprint provides a rational basis for further investigation of these formulations as nutraceutical adjuncts in canine AD. - Source: PubMed

Dysregulated STAT6 activity is implicated in asthma, atopic dermatitis, autoimmune diseases, eosinophilic disorders, and certain cancers. As such, targeting STAT6 presents a promising therapeutic strategy for these diseases. - Source: PubMed

Hu Xiao-MeiZhang HongTang Ya-SiPan Yan-YingZhuo YueDeng Shi-FengYi Xi-Qin - Bitter taste receptors are distributed in various non-taste tissues and cells, where they exert crucial roles in neuroimmune regulation and inflammatory response. In this study, a mouse model of fine particle (FPs) exposure was established by nebulized ovalbumin (OVA) inhalation to investigate the effects of FPs on renal function and structure. The experiment results revealed that inhalation of OVA led to glomerular atrophy, and renal tubular epithelial cell swelling and vacuolization, accompanied by increased levels of blood urea nitrogen and creatinine in the bloodstream. OVA inhalation induced a significant elevation in the levels of HO and malondialdehyde (MDA), while significantly decreased the activity of total superoxide dismutase (T-SOD) and the content of glutathione (GSH) in renal tissues. Furthermore, OVA downregulated Th1 cytokine IFN-γ, upregulated Th2 cytokines IL-4, IL-5 and IL-13, and activated pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) as well as genes involved in inflammatory pathways (TLR-2, TLR-4, MyD88, NF-κB, JAK-1, JAK-2, JAK-3, STAT-3, STAT-6). Notably, OVA-induced kidney injury was accompanied by the downregulation of bitter taste receptors and their downstream signaling molecules (α-gustducin, transient receptor potential melastatin 5 [Trpm5]). However, gavage administration of multi-strain probiotics significantly alleviated the toxic effects of OVA on the mouse kidneys, as evidenced by the reversal of the aforementioned abnormal changes in renal structure, biochemical indicators, oxidative stress markers, inflammatory factors, and bitter taste transduction-related molecules. Collectively, these findings indicate that OVA-induced distal organ injury, particularly renal injury, is associated with systemic inflammation and the inhibition of bitter taste transduction pathways. The protective effect of multi-strain probiotics on OVA-inhaled mice is correlated with the activation of bitter taste transduction, as well as the regulation of immune balance and inflammatory responses. - Source: PubMed

Jiao SiweiZhang RuigangPei YaochenWang MuhuaMa JiePeng XiaoguangYi Huilan - ABCB5+ dermal mesenchymal stem cells (DMSCs) regulate macrophage activation via interleukin-1 receptor antagonist (IL-1Ra), but upstream control mechanisms remain unclear. Here, we define a dual-signal model integrating inflammatory and type 2 cytokine pathways. IFNγ/LPS priming initiates IL-1Ra expression, while IL-4 signaling through IL-4Rα amplifies this response via STAT6 in both ABCB5+ DMSCs and macrophages. In coculture, ABCB5+ DMSCs drive macrophage polarization toward a CD206+/CD163+ phenotype with enrichment of CD163-expressing subsets. IL-4Rα blockade with dupilumab inhibits STAT6 activation, suppresses IL-1Ra amplification, and attenuates expansion of this IL-4Rα-dependent macrophage population. Collectively, these findings identify IL-4/IL-4Rα/STAT6 signaling as a conserved amplifier of IL-1Ra-mediated stromal-immune crosstalk. - Source: PubMed
