The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
OBJECTIVE: This study aimed to elucidate the molecular mechanisms through which CXCL2 contributes to the pathogenesis of idiopathic interstitial pneumonia (IIP). METHODS: Neutrophils were isolated, and the formation of neutrophil extracellular traps…
BBi32, isolated from a healthy infant, underwent a multi-tiered safety assessment to evaluate its genetic features, in vitro properties, and effects on gut microbiota and host biomarkers. Whole-genome sequencing (WGS) and functional annotation were p…
In avian species, the chorioallantoic membrane (CAM) is a vital, highly vascularized extraembryonic structure that supports embryonic respiration, calcium transport, and innate immune defense. In this study, we applied LC/MS/MS-based proteomics to CA…
INTRODUCTION: Rosacea is a persistent inflammatory dermatosis with a multifactorial etiology that significantly impairs patients' daily life and wellbeing. Vicenin-2, a natural flavonoid, has shown anti-inflammatory potential; however, its therapeuti…
S protein is conserved among streptococci and contributes to group A Streptococcus virulence, but the mechanisms involved are unclear. Here we used genetic, biochemical, single-molecule, in vitro and in vivo analyses to show that S protein is crucial…
Vitamin D is a secosteroid hormone traditionally recognized for its role in bone and mineral metabolism, but it is increasingly understood to also function as an important immunomodulator influencing susceptibility to and outcomes of infectious disea…
Cathelicidin CATH-2 has been reported to exert potent anti-inflammatory activity in different species though neutralizing stimuli such as lipopolysaccharide (LPS) and lipoteichoic acid (LTA). CATH-2 has been shown to inhibit Streptococcus suis (S. su…
Protamine is a polybasic drug commonly used in cardiac surgery to chemically inhibit, and thereby reverse, the anticoagulant effect of heparin. However, protamine can trigger severe anaphylaxis, with both IgE-dependent and IgE-independent mechanisms…
PURPOSE: This study aimed to examine the acute effects of continuous and interval cycling on salivary secretory immunoglobulin A (SIgA) and anti-microbial peptides. METHODS: In a randomized crossover trial, 12 healthy young untrained men (22 ± 1 year…
Effective management of infected skin wounds remains a major clinical challenge, particularly as rising antibiotic resistance compromises conventional therapies. Antimicrobial peptides (AMPs) have emerged as promising alternatives, but their clinical…
BACKGROUND: Carotid plaque vulnerability is a current feature that aids in the decision-making for ischemic stroke risk. Proteomic analysis of plaque tissue can reveal molecular indicators of instability that complement imaging findings. We sought to…
INTRODUCTION: Antimicrobial peptides (AMPs) hold promises to counter antimicrobial resistance. They cause several deleterious effects in bacterial cells by interfering with cell wall biosynthesis, DNA replication, transcription, and translation. OBJE…
BACKGROUND: The growing threat of bacterial drug resistance compels researchers to pursue new therapeutic strategies. Finegoldia magna secretes SufA, a subtilisin- like protease that plays a critical role in virulence by degrading host defense molecu…
Lung metastasis is a leading cause of breast cancer (BC)-related mortality, driven by the immunosuppressive traits of the metastatic tumor microenvironment. However, the mechanisms underlying cell-cell crosstalk in shaping immune evasion within the m…
While probiotics are increasingly consumed for health benefits, comprehensive safety assessments, particularly for novel strains, are imperative. This study aimed to conduct a holistic safety and efficacy assessment of Bifidobacterium longum subsp. i…
Due to the complex and variable microenvironment of wounds, bleeding and persistent infections have always posed significant challenges in wound treatment. Designing and developing therapeutic solutions with rapid hemostatic capabilities and antibact…
Sterile inflammation, resulting from hepatocyte death and subsequent release of damage-associated molecular patterns (DAMPs), significantly contributes to liver disease pathogenesis. Neutrophils, as primary responders to liver injury, undergo NETosis…
Alzheimer's disease is mainly caused by two proteins, Tau and Amyloid-β. While there are several cures currently being explored for it, there is no cure yet for the disease progression and prevention, but only those to alleviate the symptoms. One of…
The etiology of Alzheimer's disease (AD) remains under active debate. In this perspective, we explore the hypothesis that a primarily infection-caused chronic dysregulation and weakening of human innate immunity via the underexpression, degradation,…
INTRODUCTION: Activated polymorphonuclear neutrophils (PMN) release neutrophil extracellular traps (NETs) composed of a web-like DNA core, concomitant with nuclear histones, granular peptides and enzymes. NETs in human urine and their potential role…
