Tumour necrosis factor-alpha but not interferon-gamma is the main inducer of inducible protein-10 in skin fibroblasts from patients with atopic dermatitis.
TNF-α levels in patients with ichthyosis were increased only in those with Netherton syndrome but were much lower than in patients with psoriasis and those with AD.
Tumor necrosis factor-α (TNFα) is actively involved in inflammation processes in atopic dermatitis (AD), but the role of TNFα membrane receptors (TNFR) and their regulatory function in AD remains unclear.
Administration of CK onto DNCB-induced AD-like skin lesions in NC/Nga mice ameliorated lesion intensity scores, levels of IgE, thymus and activation-regulated chemokine (TARC), TNF-α, and IL-4 in serum and ears.
ASC-exosomes also significantly reduced mRNA expression of various inflammatory cytokines such as interleukin (IL)-4, IL-23, IL-31, and tumor necrosis factor-α (TNF-α) in AD skin lesions of Nc/Nga mice.
AST2017-01 and chrysophanol significantly suppressed the levels of histamine, immunoglobulin E, thymic stromal lymphopoietin (TSLP), interleukin (IL)-4, IL-6, and tumor necrosis factor-α in serum of AD mice.
Collectively, our results suggest that epidermal keratinocytes produce LARC/CCL20 upon stimulation with proinflammatory cytokines such as IL-1alpha and TNF-alpha, and attract CCR6-expressing immature dendritic cells and memory/effector T cells into the dermis of inflamed skin such as atopic dermatitis.
CRT effectively mitigated the secretion of pro‑inflammatory cytokines, including tumor necrosis factor‑α and interleukin 1β, as well as immune cell infiltration into skin lesions in a mouse model of AD‑like skin disease induced by dinitrochlorobenzene.
Furthermore, we found that eupatilin suppressed the levels of serum immunoglobulin E (IgE), interleukin-4 (IL-4), and AD involved cytokines, such as tumor necrosis factor α (TNFα), interferon-γ (IFN-γ), IL-1β, and thymic stromal lymphopoietin (TSLP), IL-33, IL-25 and increased the levels of filaggrin and loricrin in the oxazolone-induced AD-like mouse model.
Here we show that a deficiency of the TNF superfamily molecule TWEAK (TNFSF12) in mice results in defective maintenance of AD-specific T helper type 2 (Th2) and psoriasis-specific Th17 cells in the skin, and impaired expression of disease-characteristic chemokines and cytokines, such as CCL17 and TSLP in AD, and CCL20 and IL-19 in psoriasis.
Here, we show that the tumor necrosis factor (TNF) superfamily protein LIGHT (homologous to lymphotoxin, exhibits inducible expression, and competes with HSV glycoprotein D for binding to HVEM, a receptor expressed on T lymphocytes) is required for experimental atopic dermatitis, and LIGHT directly controls keratinocyte hyperplasia, and production of periostin, a matricellular protein that contributes to the clinical features of atopic dermatitis as well as other skin diseases such as scleroderma.
Human keratinocyte cell line (HaCa T) was stimulated with IL-4, IL-13, and TNF-α to synthesize and secrete thymic stromal lymphopoietin (TSLP), an important cytokine of immunopathogenesis in atopic dermatitis.
Immunohistochemistry revealed a significant decrease in ROR‑γt and TNF‑α positive cell expression (P<0.05) in the 15d‑PGJ2 hydrogel group compared with the AD‑group.
In addition, cordycepin reduced thymic stromal lymphopoietin (TSLP), interleukin (IL)-4, IL-6, and tumor necrosis factor-α levels in the serum of AD mice.
In addition, reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) results demonstrated that the mRNA expression of tumor necrosis factor (TNF)‑α, interferon (IFN)‑γ, interleukin (IL)‑4, IL‑13, IL‑31 and IL‑17A was reduced in ear skin following AXE administration in AD mice.
In difference to other MPs in AD, slanMo lacked expression of FcɛRI, CD1a, CD14, and CD163. slanMo from blood of patients with AD expressed increased levels of CD86 and produced IL-12 and TNF-α at higher amounts than CD14<sup>+</sup> monocytes and myeloid dendritic cells.
In the present study, the anti‑AD effects of a 70% ethanol extract of TAEE were investigated in 2,4‑dinitrochlorobenzene (DNCB)‑treated mice with AD‑like skin lesions and in tumor necrosis factor (TNF)‑α‑ and interferon (IFN)‑γ‑stimulated human keratinocytes (HaCaT cells).
In the present study, we evaluated the therapeutic effects of SF in a mouse model of <i>Dermatophagoides farinae</i> body-induced atopic dermatitis (AD) and in tumor necrosis factor-<i>α</i> and interferon-<i>γ</i>-stimulated HaCaT keratinocytes.
In vitro AD analysis of these two polymers showed significant inhibition against the release of β-hexosaminidase and tumor necrosis factor (TNF-α) from RBL-2H3 cells.
Oral administration of L. chungangensis CAU 28(T) suppressed the production of IL-4, IL-5, IL-12, IFN-γ, tumor necrosis factor-α, and thymus- and activation-regulated chemokine (TARC) in skin lesions, indicating that it strongly drives the local immune system with efficacy comparable to that of tacrolimus, a topical immunomodulatory drug used for the treatment of atopic dermatitis.
Polymorphisms in the genes encoding tumour necrosis factor-alpha (TNFA-238 G/A, -308 G/A), interleukin (IL)-1beta (IL1B-511 T/C, +3953 T/C), IL-6 (IL6-174 C/G), IL-10 (IL10-1082 A/G) and the IL-1 receptor antagonist (IL1RN intron 2) were investigated in German patients with AD (n = 94) and in healthy nonatopic individuals (n = 214) by polymerase chain reaction-based methods and direct cycle sequencing.
