TNF- α promotes CXCL-1/8 production in keratinocytes by downregulating galectin-3 through NF-κB and hsa-miR-27a-3p pathway to contribute psoriasis development
CONCLUSION: TNF-α initiates psoriatic inflammation by increasing CXCL-1/8 in keratinocytes mediated by the axis of NF-κB-hsa-miR-27a-3p-galectin-3 pathway.PMID:37358143 | DOI:10.1080/08923973.2023.2229510

Activation of ryanodine-sensitive calcium store drives pseudo-allergic dermatitis via Mas-related G protein-coupled receptor X2 in mast cells
Mast cell (MC) activation is implicated in the pathogenesis of multiple immunodysregulatory skin disorders. Activation of an IgE-independent pseudo-allergic route has been recently found to be mainly mediated via Mas-Related G protein-coupled receptor X2 (MRGPRX2). Ryanodine receptor (RYR) regulates intracellular calcium liberation. Calcium mobilization is critical in the regulation of MC functional programs. However, the role of RYR in MRGPRX2-mediated pseudo-allergic skin reaction has not been fully addressed. To study the role of RYR in vivo, we established a murine skin pseudo-allergic reaction model. RYR inhibitor att...

TMEM232 Promotes the Inflammatory Response in Atopic Dermatitis via NF- κB and STAT3 Signaling Pathways
CONCLUSION: The study first outlines the function of TMEM232. It is involved in regulating inflammation in AD and may be a potential target for AD treatment.PMID:36928730 | DOI:10.1093/bjd/ljad078

Inhibition of serum and glucocorticoid-regulated protein kinase-1 aggravates imiquimod-induced psoriatic dermatitis and enhances proinflammatory cytokine expression via the NF-kappaB pathway
In this study, we found that SGK1 expression was decreased in macrophages from psoriasis patients. Moreover, a specific pharmacological SGK1 inhibitor, EMD638683, significantly enhanced imiquimod (IMQ)-mediated TLR7/8 activity and proinflammatory cytokine production in RAW264.7 cells, and this result was confirmed by SGK1 siRNA.

The Role of Collagen VI α6 Chain Gene in Atopic Dermatitis
CONCLUSION: The reduction of epidermal COL6A6 due to the genetic mutation can cause skin barrier damage and it can contributes to the early onset of AD. COL6A6 is induced by IL-4 and IL-13, and it may play a role in fibrotic remodeling and inflammatory processes, which are major features of AD.PMID:35221595 | PMC:PMC8831303 | DOI:10.5021/ad.2022.34.1.46
