IL-10 Sensing by Lung Interstitial Macrophages Prevents Bacterial Dysbiosis-Driven Pulmonary Inflammation and Maintains Immune Homeostasis

1. Research Background The pathogenesis of chronic lung inflammation and pulmonary fibrosis remains unclear, particularly regarding the interaction between pulmonary commensal microbiota and the immune system. While interleukin-10 (IL-10), a key anti-inflammatory cytokine, has been extensively studied in gut homeostasis, its role in pulmonary immun...

Alcaligenes faecalis Induces Intestinal T Helper 17 Cells by Promoting E3 Ubiquitin Ligase TRIM21-Mediated FBXW7 Degradation

1. Research Background Intestinal Th17 cells play a central role in maintaining mucosal immune homeostasis and defending against pathogen infections. Previous studies identified segmented filamentous bacteria (SFB) as key microbes inducing intestinal Th17 cells, but controversies exist regarding SFB colonization in adult intestines: 1. Clinical Par...

Computationally Designed Proteins Mimic Antibody Immune Evasion in Viral Evolution

Academic Background The continuous mutation of SARS-CoV-2 has posed ongoing challenges to the efficacy of vaccines and antibody therapies. Traditional evaluation methods can only test against existing variants and fail to predict future immune escape mutations. To address this, Noor Youssef and colleagues developed the EVE-Vax (Evolutionary Variant...

Vaccination of Nonhuman Primates Elicits a Broadly Neutralizing Antibody Lineage Targeting a Quaternary Epitope on the HIV-1 Env Trimer

1. Research Background The envelope glycoprotein (Env) of human immunodeficiency virus type 1 (HIV-1) is the primary target of neutralizing antibodies, but its high variability poses challenges for vaccine development. Broadly neutralizing antibodies (bnAbs) are rare in natural infections and typically require years to emerge. Although Env trimer m...

Cross-Feeding Creates Tipping Points in Microbiome Diversity

Academic Background Microbiomes are among the most diverse ecosystems on Earth, consisting of hundreds of functionally distinct microbial populations interacting through complex resource exchange networks. However, a long-standing unresolved question is: How is this extraordinary diversity maintained through metabolic interactions among populations...

Ensemble Learning Based on Matrix Completion Improves Microbe-Disease Association Prediction

Academic Background and Research Problem Microorganisms, as one of the most widely distributed forms of life on Earth, are closely related to oceans, soil, and the human body. The human body contains approximately 350 trillion microbial cells, which are intricately linked to human health and the onset and progression of diseases. In recent years, w...

Antigen Spatial-Matching Polyaptamer Nanostructure to Block Coronavirus Infection and Alleviate Inflammation

Academic Background In recent years, multiple outbreaks caused by coronaviruses have occurred globally, such as SARS (Severe Acute Respiratory Syndrome), MERS (Middle East Respiratory Syndrome), and COVID-19 (Novel Coronavirus Pneumonia). These pandemics have not only posed a serious threat to human health but also exposed the inadequacy of emergen...

Live Bacterial Chemistry in Biomedicine

Background Introduction The application of live bacteria in the biomedical field has garnered significant attention in recent years. Traditionally, bacteria were viewed as pathogens that needed to be eradicated. However, with the advancement of modern bacteriology, there has been a growing recognition of the complex symbiotic relationship between b...

Pseudomonas fluorescens–Based Biogenic Silver Nanoparticles: A Green Solution for Brown Leaf Spot Disease in Rice

Academic Background Rice (Oryza sativa L.) is a globally important food crop, providing a primary source of calories for approximately one-fifth of the world’s population. However, rice production faces various biotic and abiotic stresses, leading to reduced yields. Among these, rice brown leaf spot disease, caused by the fungal pathogen Cochliobol...

Synthesis, Physicochemical Characterization, and Antimicrobial Evaluation of Ureasil-Polyether Coatings with Silver Nanoparticles for Hospital Devices

Research Background Nosocomial infections are a common and serious problem in healthcare settings, particularly on reusable medical devices, where cross-contamination and biofilm formation are major causes. To address this challenge, researchers have begun exploring the use of coating materials containing metallic nanoparticles to prevent microbial...
