IL-33 contributes to disease severity in Psoriasis-like models of mouse.
Cytokine. 2019 Jul , 119:159-167.

Immune cells infiltrating the psoriatic skin secrete high amounts of pro-inflammatory cytokines IL-17, TNF-α, IL-21 and IL-36 resulting in chronic inflammation. However, the exact cellular and molecular mechanisms have not been fully understood. We report here elevation of IL-33 expression in psoriatic lesions. Studies in imiquimod (IMQ)-induced mice with psoriatic inflammation confirmed a critical role for IL-33 in driving the disease. IL-33 reduces the CD4 and CD8 cells, inhibits autophagy (...)

Association of plasma and urine metals levels with kidney function: A population-based cross-sectional study in China.
Chemosphere. 2019 Jul , 226:321-328.

Although environmental exposure to multiple metals is common, epidemiological studies on the associations of exposure to 23 metals with kidney function have not been analyzed. We aimed to investigate the associations of 23 metals levels with renal function.

Martínez-Navarro FJ et al.
Models of human psoriasis: Zebrafish the newly appointed player.
Dev. Comp. Immunol.. 2019 Aug , 97:76-87.

Psoriasis is a human chronic, immune disease with severe cutaneous and systemic manifestations. Its prevalence, among the world population, highly varies with ethnicity and geography, but not sex from remarkable low levels in Asia to 2.3% in Spain, or an impressive 11.5% in Norway. The pathogenesis of psoriasis derives from complex genetic and environmental interactions, which creates aberrant crosstalk between keratinocytes and variated immune cell, resulting in open amplified inflammatory (...)

Lloyd-Lavery A et al.
What's new in atopic eczema? An analysis of systematic reviews published in 2016. Part 3: nomenclature and outcome assessment.
Clin. Exp. Dermatol.. 2019 Jun , 44, (4):376-380.

This review forms part of a series of annual updates that summarize the evidence base for atopic eczema (AE). It presents the key findings from 11 systematic reviews published in 2016 that focus on AE outcome assessment, disease impact and nomenclature. Systematic reviews on the treatment and prevention of AE are summarized in Part 1 of this update, and systematic reviews on the epidemiology of and risk factors for AE are summarized in Part 2. Six reviews summarized what outcome measurement (...)

Discovery of a class of highly potent Janus Kinase 1/2 (JAK1/2) inhibitors demonstrating effective cell-based blockade of IL-13 signaling.
Bioorg. Med. Chem. Lett.. 2019 Jun 15, 29, (12):1522-1531.

Disruption of interleukin-13 (IL-13) signaling with large molecule antibody therapies has shown promise in diseases of allergic inflammation. Given that IL-13 recruits several members of the Janus Kinase family (JAK1, JAK2, and TYK2) to its receptor complex, JAK inhibition may offer an alternate small molecule approach to disrupting IL-13 signaling. Herein we demonstrate that JAK1 is likely the isoform most important to IL-13 signaling. Structure-based design was then used to improve the (...)

Choi EJ et al.
Effect of cinnamamides on atopic dermatitis through regulation of IL-4 in CD4 cells.
J Enzyme Inhib Med Chem. 2019 Dec , 34, (1):613-619.

This study aimed to evaluate the effects of cinnamamides on atopic dermatitis (AD) and the mechanisms underlying these effects. To this end, the actions of two cinnamamides, (E)-3-(4-hydroxyphenyl)-N-phenylethyl acrylamide (NCT) and N-trans-coumaroyltyramine (NCPA), were determined on AD by orally administering them to mice. Oral administration of the cinnamamides ameliorated the increase in epidermal and dermal thickness as well as mast cell infiltration. Cinnamamides suppressed serum (...)
