Psoriasis is associated with low serum levels of hydrogen sulfide, a potential anti-inflammatory molecule.
Tohoku J. Exp. Med.

Hide Abstract
Psoriasis, characterized by circumscribed, red, thickened plaques with an overlying silver-white scale, is a common T-cell-mediated chronic inflammatory skin disease. Although hydrogen sulfide (H(2)S) has been shown to be a signaling molecule with both pro- or anti-inflammatory effects, its relationship with psoriasis has not been elucidated. In the present study, 15 patients with chronic progressive psoriasis and 15 healthy volunteers were investigated. Serum H(2)S levels in psoriasis patients were significantly lower than those of healthy controls (16.69 ± 5.47 ?M vs. 34.5 ± 6.39 ?M). In contrast, serum levels of tumor necrosis factor alpha (TNF-?), interleukin-6 (IL-6) and interleukin-8 (IL-8) were significantly higher in psoriasis patients than healthy controls (22.88 ± 6.24 pg/ml vs. 12.07 ± 3.68 pg/ml; 61.47 ± 8.21 pg/ml vs. 31.54 ± 13.73 pg/ml; and 39.43 ± 8.56 pg/ml vs. 20.55 ± 6.45 pg/ml, respectively). The serum H(2)S levels negatively correlated with clinical disease severity. Furthermore, treatment of HaCaT human keratinocytes with TNF-? increased the levels of nitric oxide (NO), IL-6 and IL-8 (32.21 ± 5.71 ?M vs. 3.22 ± 0.98 ?M; 203.96 ± 13.16 pg/ml vs. 13.57 ± 3.75 pg/ml; and 301.24 ± 30.17 pg/ml vs. 29.06 ± 10.91 pg/ml, respectively) in the culture media. Exogenous H(2)S inhibited the TNF-?-mediated upregulation of NO, IL-6 and IL-8 in a dose-dependent manner. In addition, H(2)S inhibited TNF-?-mediated activation of p38, extracellular-signal-regulated kinase and nuclear factor kappa B. In conclusion, H(2)S may play a protective role in the pathogenesis of psoriasis. H(2)S-releasing agents may be promising therapeutics for psoriasis.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
