The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Periodontitis, a multifactorial inflammatory disease driven by microbial dysbiosis, dysregulated immunity, and oxidative stress, demands therapeutic strategies that concurrently address interconnected pathological pathways. Here, a biomimetic lipid d…
BACKGROUND: Dental plaque is a highly organized polymicrobial biofilm, in which extracellular DNA serves as a vital structural and functional component of the extracellular matrix. The human antimicrobial peptide LL-37 plays an important role in oral…
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…
Wound healing and tissue regeneration are essential for maintaining skin integrity in the face of mechanical, chemical, or thermal damage. In adult mammals, the wound healing process may include complications leading to chronic wounds and hypertrophi…
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…
Urinary proteins offer multifaceted insights into tissue repair, dysfunction, and renal health, with significant implications for both human and veterinary medicine. However, marine mammal medicine lacks comprehensive studies on urine protein composi…
Quercetin-loaded cellulose nanocrystals (QL-CNC) were developed as a reactive oxygen species (ROS)-responsive nanocarrier for the targeted treatment of rosacea. A murine model of rosacea-like dermatitis was induced using LL-37. The therapeutic effica…
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…
Cathelicidins, a diverse family of host defence peptides (HDPs) in vertebrates, are recognized for their potential in combating resistant microorganisms and their varied biological functions. While extensive studies have focused on mammalian cathelic…
There is an urgent need for new antimicrobial agents to address the emerging antimicrobial resistance and the lack of novel antibiotics on the market. Antimicrobial peptides (AMPs) have gained significant interest as potential antibiotics over the pa…
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…
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…
To combat the growing challenge of bacterial infections, sonodynamic antibacterial technology has gained increasing attention. However, current approaches still face limitations, including suboptimal efficacy and a narrow antibacterial spectrum (only…
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…
Cathelicidins are crucial antimicrobial peptides (AMPs) that play a key role in the innate immunity of marine vertebrates. The pygmy sperm whale (Kogia breviceps), which resides in environments populated by diverse microbial communities, faces comple…
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…
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic urinary disorder with unclear pathogenesis. Previous studies identified BTK as a hub gene potentially involved in IC/BPS. This study investigates BTK's role in mast cell (MC) activatio…
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…
