Lack of Annexin A1 Exacerbates Inflammatory Response in Acute Endometritis Model
In conclusion, a lack of endogenous AnxA1 exacerbated the inflammatory response in an endometritis modelvia NLRP3 dysregulation, increased uterine mast cell activation, and plasma pro-inflammatory cytokine release. (Source: Inflammation)

4-Octyl Itaconate Inhibits Proinflammatory Cytokine Production in Behcet ’s Uveitis and Experimental Autoimmune Uveitis
Abstract4-octyl itaconate (4-OI) is an anti-inflammatory metabolite that activates the nuclear-factor-E2-related factor 2 (NRF2) signaling. In the current work, we investigated whether 4-OI could affect the production of proinflammatory cytokines in Behcet ’s uveitis (BU) and experimental autoimmune uveitis (EAU). Peripheral blood mononuclear cells (PBMCs) of active BU patients and healthy individuals within vitro 4-OI treatment were performed to assess the influence of 4-OI on the proinflammatory cytokine production. EAU was induced and used for investigating the influence of 4-OI on the proinflammatory cytokine product...

Scutellarin Alleviates Ovalbumin-Induced Airway Remodeling in Mice and TGF- β-Induced Pro-fibrotic Phenotype in Human Bronchial Epithelial Cells via MAPK and Smad2/3 Signaling Pathways
In conclusion, scutellarin can inactivate the Smad/MAPK pathways to suppress the TGF- β1-stimulated epithelial fibrosis and EMT and relieve airway inflammation and remodeling in asthma. This study provides a potential therapeutic strategy for asthma. (Source: Inflammation)

Sodium Butyrate Ameliorates Atopic Dermatitis-Induced Inflammation by Inhibiting HDAC3-Mediated STAT1 and NF- κB Pathway
AbstractA topic dermatitis (AD) is a common chronic and recurrent skin disorder. The protective effects of sodium butyrate (NaB), a metabolite of short-chain fatty acid breakdown by the gut microbiota, have been widely reported in numerous inflammatory diseases. However, the effect of NaB treatment alone on AD has not been reported. In the current study, AD was induced in BALB/c mice with 2,4-dinitrochlorobenzene (DNCB) for 28 days with NaB (200 mg/kg) treatment by gavage. NaB attenuated AD-induced skin bleeding, scarring, dryness, abrasions and erosions. In addition, NaB inhibited inflammatory cells infiltration and atten...

MALT1 Protease Regulates T-Cell Immunity via the mTOR Pathway in Oral Lichen Planus
AbstractOral lichen planus (OLP) is a T cell –mediated immune mucosal disease of unknown pathogenesis. Whether mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1), an intracellular signaling protein, is involved in the T-cell immune dysfunction of OLP remains elusive. MALT1 expression in local and peripheral T cells of OLP and controls was analyzed using immunohistochemistry, multiplex immunohistochemistry, and flow cytometry. The expression of MALT1 in activated Jurkat T cells incubated with either OLP plasma or interleukin (IL)-7/IL-15 was determined by flow cytometry. The effects of MALT1 and me...

Nicorandil Regulates Ferroptosis and Mitigates Septic Cardiomyopathy via TLR4/SLC7A11 Signaling Pathway
This study mainly explored the role of nicorandil in regulating ferroptosis and alleviating septic cardiomyopathy through toll-like receptor (TLR) 4/solute carrier family 7 member 11 (SLC7A11) signaling pathway. Twenty-four male SD rats were randomly divided into control, Nic (nicorandil), LPS (lipopolysaccharide), and LPS + Nic groups and given echocardiography. A detection kit was applied to measure the levels of lactic dehydrogenase (LDH), cardiac troponin I (cTnI), and creatine kinase-MB (CK-MB); HE staining and the levels of glutathione (GSH), malondialdehyde (MDA), total iron, and Fe2+ of myocardial tissues were dete...

Multiple gene-drug prediction tool reveals Rosiglitazone based treatment pathway for non-segmental vitiligo
In this study, we performed a comprehensive analysis of two vitiligo microarray datasets from the GEO database using bioinformatics tools to identify 297 up-regulated mRNAs and 186 down-regulated mRNAs, revealing important roles for pathways related to melanin synthesis, tyrosine metabolism, and inflammatory factors, such as “PPAR signaling pathway”, “tyrosine metabolism”, “nonalcoholic fatty liver disease (NAFLD) pathway”, “melanogenesis”, and “IL-17 signaling pathway”. Combining the Search Tool for Interacting Chemicals (STITCH) database 5.0 and the drug-gene interaction database 3.0 (DGIdb), we id en...
