IL-24 Contributes to Neutrophilic Asthma in an IL-17A-Dependent Manner and Is Suppressed by IL-37
CONCLUSIONS: IL-24 aggravated neutrophilic airway inflammation by increasing epithelium-derived IL-17A production, which could be suppressed by IL-37. Targeting the IL-24/IL-17A signaling axis is a potential strategy, and IL-37 is a potential candidate agent for alleviating neutrophilic airway inflammation in asthma.PMID:36174993 | PMC:PMC9523421 | DOI:10.4168/aair.2022.14.5.505

Spray drying siRNA-lipid nanoparticles for dry powder pulmonary delivery
This study verifies the successful spray drying procedure of LNP-siRNA systems maintaining their integrity and mediating strong gene silencing efficiency on mRNA and protein levels both in vitro and ex vivo. The successful spray drying procedure of LNP-siRNA formulations in 5% lactose solution creates a novel siRNA-based therapy option to target respiratory diseases such as lung cancer, asthma, COPD, cystic fibrosis and viral infections.PMID:36126785 | DOI:10.1016/j.jconrel.2022.09.021

Blockade of Mbd2 by siRNA-loaded liposomes protects mice against OVA-induced allergic airway inflammation via repressing M2 macrophage production
ConclusionsThe above data indicate that Mbd2 implicates in the pathogenesis of asthma predominantly by regulating the polarization of M2 macrophages, which supports that Mbd2 could be a viable target for treatment of asthma in clinical settings.

Acetate, a gut bacterial product, ameliorates ischemia-reperfusion induced acute lung injury in rats
In this study, we examine whether SCFAs have protective effects against IR-induced ALI and explore possible protective mechanisms. IR-induced ALI was established by 40 min ischemia followed by 60 min reperfusion in isolated perfused rat lungs. Rats were randomly assigned to one of six groups: control, control + acetate (400 mg/kg), IR, and IR + acetate at one of three dosages (100, 200, 400 mg/kg). Bronchoalveolar lavage fluids (BALF) and lung tissues were obtained and analyzed at the end of the experiment. In vitro, mouse lung epithelial cells (MLE-12) subjected to hypoxia-reoxygenation (HR) were pretreated with acetate (...

Current Drug Targeting using siRNAbased Nano Therapeutics for Pulmonary Diseases
Curr Pharm Des. 2022 Jul 27. doi: 10.2174/1381612828666220727144223. Online ahead of print.ABSTRACTThe importance of siRNA in nano drug delivery systems to target important pulmonary disorders such as chronic obstructive pulmonary disease (COPD), asthma, lung cancer, and others is reviewed in this perspective. The great majority of lung illnesses are caused by protein misfolding. As a result, siRNA-based therapies are increasingly being used to target the gene. Given the difficulties of delivering bare siRNA, siRNA protection may ensure its efficacy in gene therapy. These issues could be solved with a nano-based siRNA deli...

TL1A/DR3 Axis, A Key Target of TNF-a, Augments the Epithelial –Mesenchymal Transformation of Epithelial Cells in OVA-Induced Asthma
This study first proposed that the TL1A/DR3 axis was significantly upregulated in patients and mice with both asthma and high TNF-a expression and in TNF-a-stimulated epithelial Beas-2B cells. Two independent approaches were used to demonstrate that the TL1A/DR3 axis of mice was strongly correlated with TNF-a in terms of exacerbating asthmatic epithelial–mesenchymal transformation (EMT). First, high expression levels of EMT proteins (e.g., collagen I, fibronectin, N-cadherin, and vimentin) and TL1A/DR3 axis were observed when mice airways were stimulated by recombinant mouse TNF-a protein. Moreover, EMT protein and TL1A/...

The TL1A-DR3 Axis in Asthma: Membrane-Bound and Secreted TL1A Co-Determined the Development of Airway Remodeling
CONCLUSIONS: Our results confirm differential TL1A expression (including its secreted and non-secreted form) in asthma, which modulates remodeling. The shared mechanism of action by which nsTL1A and secreted TL1A exert their effects on asthma development might be mediated via the nuclear factor-κB pathway. The TL1A-DR3 axis presents a promising therapeutic target in asthma.PMID:35255540 | DOI:10.4168/aair.2022.14.2.233
