Activation of aryl hydrocarbon receptor by benzoapyrene increases interleukin 33 expression and eosinophil infiltration in a mouse model of allergic airway inflammation
AbstractWe recently demonstrated that benzo[a]pyrene (BaP), the aryl hydrocarbon receptor (AhR) ligand, directly contributes to aggravation of cutaneous allergy in a mouse model of allergic dermatitis. The present study aimed to determine whether BaP ‐induced AhR activation results in development of airway inflammation. Initially, the potential for a direct relationship between BaP‐induced AhR activation and airway inflammation was investigated in vivo, using a mouse model of type 2 helper T cell (Th2) hapten toluene‐2,4‐diisocyanate (TD I)‐induced airway inflammation. Mice were orally administered BaP at 48, 24,...

Molecules, Vol. 25, Pages 1554: Anti-Allergic and Anti-Inflammatory Effects of Undecane on Mast Cells and Keratinocytes
Park The critical roles of keratinocytes and resident mast cells in skin allergy and inflammation have been highlighted in many studies. Cyclic adenosine monophosphate (cAMP), the intracellular second messenger, has also recently emerged as a target molecule in the immune reaction underlying inflammatory skin conditions. Here, we investigated whether undecane, a naturally occurring plant compound, has anti-allergic and anti-inflammatory activities on sensitized rat basophilic leukemia (RBL-2H3) mast cells and HaCaT keratinocytes and we further explored the potential involvement of the cAMP as a molecular target for un...

Plasma cell gingivitis due to cosmetics related iodopropynyl butylcarbamate (ipbc) allergy in a teenage female patient masking as desquamative gingivitis.
We present a case of PCG in a 13 year old female patient which clinically presented as generalized desquamative gingivitis involving the facial aspects of the attached and marginal gingiva that persisted despite substituting to a non flavored dentifrice and failure to elicit any suspected drug or food allergies. Dermatologic patch testing proved positive for Iodopropynyl Butylcarbamate (IPBC), a water based preservative or biocide used in personal care products. Microscopically, there was an intense inflammatory infiltrate in the lamina propria composed predominantly of mature plasma cells. Immunohistochemistry and in situ...

Current Clinical Trials in Pemphigus and Pemphigoid
Conclusions The clinical trials discussed here, which include several trials investigating novel therapeutic targets, demonstrate that translational research in pemphigus and pemphigoid is a fast-growing field. We thus expect that several novel treatments will be shortly available for the treatment of pemphigus and pemphigoid patients. Given the high, and thus far unmet, medical need in this field (110), this is highly encouraging and will hopefully improve the quality of life of the affected patients. In addition to the compounds and targets described here, several new targets have been recently identified in preclinical...

Innate Lymphoid Cells: Expression of PD-1 and Other Checkpoints in Normal and Pathological Conditions
Conclusions and Future Perspectives It is now evident that NK/ILC family plays a pivotal role in the immune defenses. Recent studies in murine and human settings demonstrated that the expression of several inhibitory checkpoints, that may be detrimental in the tumor context, is not restricted to T lymphocytes, revealing an important, yet poorly appreciated, contribution of their expression on innate immune cells. Thus, in the recent years different immunotherapy approaches, based on the blockade of inhibitory NK cell receptors, have been developed in order to unleash NK cell cytotoxicity. This is particularly important in...

Innate Lymphoid Cells in Helminth Infections —Obligatory or Accessory?
Conclusion ILC2s are clearly an inherent feature of the immune response to helminth infection, and in all probability their evolution has been driven by the threat of parasites. While in experimental model systems they are not always found to be essential, they are often center stage, particularly in the early phases of infection of each helminth system so far analyzed. They also form an important conceptual and mechanistic link with the allergic response that will allow us to understand in more detail the genesis and control of allergic disorders. In this respect, a much fuller analysis of ILC biology and function in the...

Inhibitory Effects of Pterocarpus santalinus Extract against IgE/Antigen-Sensitized Mast Cells and Atopic Dermatitis-Like Skin Lesions
Planta Med DOI: 10.1055/a-0824-1282 Pterocarpus santalinus has been traditionally used as a medicinal plant owing to its anti-inflammatory, anthelmintic, tonic, antihyperglycemic, and diaphoretic properties. We hypothesized that P. santalinus might have therapeutic potential in alleviating allergy and atopic dermatitis. Thus, we investigated the inhibitory effects of P. santalinus extract against allergic responses and 2,4-dinitrochlorobenzene-induced atopic dermatitis-like dorsal skin lesions using immunoglobulin E-sensitized rat basophilic leukemia-2H3 mast cells and NC/Nga mice. Degranulation and enzyme-linked immuno...

Cryptotanshinone inhibits IgE ‑mediated degranulation through inhibition of spleen tyrosine kinase and tyrosine‑protein kinase phosphorylation in mast cells.
Cryptotanshinone inhibits IgE‑mediated degranulation through inhibition of spleen tyrosine kinase and tyrosine‑protein kinase phosphorylation in mast cells. Mol Med Rep. 2018 May 22;: Authors: Buyanravjikh S, Han S, Lee S, Jeong AL, Ka HI, Park JY, Boldbaatar A, Lim JS, Lee MS, Yang Y Abstract Atopic dermatitis (AD) is a type of chronic skin inflammation and one of the most common relapsing allergic diseases, which presents with a severe rash and itchy skin lesions. The pathogenesis of AD is primarily associated with hyper‑activated mast cells, which makes them an effective treatment target. Afte...

The benzene metabolite 1,4-benzoquinone reduces regulatory T-cell function: A  potential mechanism for tobacco smoke–associated atopic dermatitis
Exposure to environmental chemicals can contribute to the development or exacerbation of atopic dermatitis (AD). Benzene is one of the chemicals previously been implicated in the etiology  of AD.1 Albeit a ubiquitous environmental chemical, nonoccupational exposure to benzene mainly results from active or passive tobacco smoke exposure in homes or public places. Exposure to benzene has been shown to exert diverse effects on blood cells, in particular on lymphocytes. Although chronic exposure to high levels of benzene may cause leukemia and probably other lymphohematopoietic cancers, already low levels of benzene have been...

The Potential Role of T Helper Cell 22 and IL-22 in Immunopathogenesis of Multiple Sclerosis
Conclusion Recent evidence shows changes in frequency and function of Th22 and its cytokine IL-22 in patients with MS, which suggests a potential relationship between Th22 cells, IL-22 levels, and the development and disease course of MS and its response to treatment. How Th22 cells and IL-22 levels affect the disease course of MS requires further elucidation. Additional studies on the immunopathogenesis of MS, specifically the roles Th22 cells and IL-22 cytokines may play in disease progression, are warranted and may lead to the development of new therapeutic strategies for treating neuro-inflammatory diseases, such as MS...
