Long-term inhibition of protease hypersensitivity by initial immunological cross-regulation and epigenetic memory in lung stromal cells - Nature Immunology
Abstract Prevention and regulation of excessive inflammation is a key target to protect against inflammatory pathologies such as autoimmunity and allergy. In a mouse model of acute lung protease hypersensitivity, we assessed the efficacy of immunological cross-regulation to mitigate pathogenic inflammation.
Neuroepithelial VIP–VIPR1 interactions differentially control enteric type 1 and type 2 immunity - Nature Immunology
Abstract The nervous and immune systems cooperate to regulate mucosal barrier integrity. Nevertheless, whether enteric neurons establish neuroepithelial interactions to coordinate immunity remains elusive. Here, we identified neuroepithelial interactions that differentially control intestinal type 1 and type 2 immunity.
Distinctive CD39+CD9+ lung interstitial macrophages suppress IL-23/Th17-mediated neutrophilic asthma by inhibiting NETosis - Nature Communications
Abstract The IL-23-Th17 axis is responsible for neutrophilic inflammation in various inflammatory diseases. Here, we discover a potential pathway to inhibit neutrophilic asthma. In our neutrophil-dominant asthma (NDA) model, single-cell RNA-seq analysis identifies a subpopulation of CD39+CD9+ interstitial macrophages (IMs) suppressed by IL-23 in NDA conditions but increased by an IL-23 inhibitor αIL-23p19.
Airway epithelial CD47 plays a critical role in inducing influenza virus-mediated bacterial super-infection - Nature Communications
Abstract Respiratory viral infection increases host susceptibility to secondary bacterial infections, yet the precise dynamics within airway epithelia remain elusive. Here, we elucidate the pivotal role of CD47 in the airway epithelium during bacterial super-infection. We demonstrated that upon influenza virus infection, CD47 expression was upregulated and localized on the apical surface of ciliated cells within primary human nasal or bronchial epithelial cells.
Nonaqueous arylated quinone catholytes for lithium-organic flow batteries
Chemically modified organic redox couples have the advantages of tunable redox properties, high solubility, environmental benignity, and cost effectiveness. Inspired from nature, a series of quinone derivatives bearing electron-donating methoxy or electron-withdrawing trifluoromethyl groups are synthesized in moderate to high yields by the Pd-catalyzed Suzuki cross-coupling reactions.
