Lactiplantibacillus plantarum GUANKE Alleviates Intestinal Barrier Damage Caused by Influenza Infection in Mice.

Influenza, a highly transmissible acute respiratory illness caused by influenza viruses, is responsible for annual seasonal epidemics and poses a substantial global disease burden. While primarily recognized for its respiratory manifestations, influenza infection exhibits significant extrapulmonary effects, particularly through disrupting gut microbiota composition and compromising intestinal barrier integrity. This study investigates the protective efficacy of Lactiplantibacillus plantarum strain GUANKE against influenza-associated intestinal pathology in a murine model.

Immunomodulatory and anti-inflammatory properties of dictamnine-free phytopharmaceuticals from Dictamni Cortex with phototoxicity evaluation.

Ethnopharmacological Relevance: Dictamni Cortex (Dictamnus dasycarpus root barks) has been widely applied across Asia for inflammatory dermatological conditions, including eczema, pruritus, allergies, and urticaria. Among the active compounds in Dictamni Cortex, dictamnine exhibits notable anti-inflammatory and antipruritic properties, contributing to its therapeutic effects against skin inflammation. However, dictamnine, a furoquinoline alkaloid, shares a structural framework with linear furanocoumarines such as 8-methoxypsoralen and 5-methoxypsoralen, which are known for their photoactive properties.

CCN2 mediates fibroblast-macrophage interaction in knee arthrofibrosis based on single-cell RNA-seq analysis.

Knee arthrofibrosis, characterized by excessive matrix protein production and deposition, substantially impairs basic daily functions, causing considerable distress and financial burden. However, the underlying pathomechanisms remain unclear. Here, we characterized the heterogeneous cell populations and cellular pathways by combination of flow cytometry and single-cell RNA-seq analysis of synovial tissues from six patients with or without knee arthrofibrosis.

Administration of GUANKE alleviates SARS-CoV-2-induced pneumonia in mice.

Unlabelled: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) targets epithelial cells in the respiratory tract, triggering an acute proinflammatory response and chronic lung inflammation. Probiotic supplementation has shown promise in reducing the nasopharyngeal SARS-CoV-2 viral load, diminishing symptom frequency and duration, and mitigating inflammation; thus, it is a potential strategy for treating coronavirus disease 2019 (COVID-19), which is caused by SARS-CoV-2 infection. In this study, we evaluated the effects of the oral administration of the GUANKE strain, a gram-positive bacterium originally isolated from a healthy individual, on SARS-CoV-2 infection in a human ACE2 transgenic mouse model.

Local Electric Potential-Driven Nanofluidic Ion Transport for Ultrasensitive Biochemical Sensing.

Nanofluidic biosensors have been widely used for detection of analytes based on the change of system resistance before and after target-probe interactions. However, their sensitivity is limited when system resistance barely changes toward low-concentration targets. Here, we proposed a strategy to address this issue by means of target-induced change of local membrane potential under relatively unchanged system resistance.
