The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
The fever response is triggered during infection and inflammation, but the importance of this response for the function of antimicrobial peptides (AMPs) remains unknown. We discovered that the activity of the human AMP LL-37 is temperature-dependent…
To identify the differential properties of anti-microbial peptides (AMPs) and proteins in the burying beetle Nicrophorus quadripunctatus and the short sexton beetle Necrodes littoralis, we performed comparative transcriptomic analyses, quantified gen…
Periapical periodontitis (AP) is an inflammatory disease caused by persistent endodontic biofilms, and its treatment remains challenging because conventional root canal therapy sometimes fails to achieve effective disinfection and tissue regeneration…
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…
Innate immune-related genes are shaped by strong selection pressures due to host-pathogen co-evolution, yet the evolutionary trajectory of cathelicidin antimicrobial (AMP) gene is poorly understood. Despite their central role in innate immunity, the…
Mesenchymal stem cells (MSCs) have emerged as promising alternatives to fight drug-resistant bacterial infections. This study investigates the antibacterial activity of palatal adipose tissue-derived MSCs (PMSCs), particularly when cultured within a…
BACKGROUND AND AIMS: Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause small intestinal injury and dysbiosis. Although NSAID-induced dysbiosis is well-characterized and contributes to enteropathy, the changes in host-bacterial interactions duri…
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…
Malaria control is challenged by the emergence of resistance to virtually all antimalarial drugs, from the frontline artemisinin to other classes, highlighting the critical need for new therapies. This study demonstrates that the human antimicrobial…
Chronic diabetic wounds do not heal and are often accompanied by infections and poor angiogenesis. We have made a two-layered PVA/CS composite hydrogel MN-CL patch, which has antibacterial, immunoregulatory, and pro-healing properties. The needle tip…
INTRODUCTION: Elevated levels of serum Vitamin D (VitD) and increased expression of its receptor on peripheral blood cells have been reported in individuals who have been exposed to HIV-1 yet remain seronegative (HESN). This study aimed to investigat…
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…
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…
Mastitis is a major cause of economic losses in dairy production; however, its prevention and treatment remain challenging. Under field conditions, antimicrobial drugs are frequently administered when somatic cell counts (SCCs) are elevated and signs…
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…
Dynamic changes in lipid membrane composition are a common response to stress, often involving shifts in key lipid molecules. Phosphatidic acid (PA), a central precursor in lipid biosynthesis, accumulates when anionic phospholipid synthesis is blocke…
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…
The escalating global threat of antimicrobial resistance (AMR) and chronic biofilm-associated infections underscores the urgent need for novel therapeutic agents. Antimicrobial peptides (AMPs) offer a promising alternative due to their potent activit…
Host defense peptides (HDPs), ancestral effectors of innate immunity, have emerged as pleiotropic regulators transcending their antimicrobial origins. This review critically examines the complex interplay among HDPs, hemostasis, and tissue repair. We…
The rise of antimicrobial resistance (AMR) has outpaced the development of new antibiotics, necessitating alternative therapeutic strategies that do not rely on conventional bactericidal approaches. Quorum-sensing (QS), a bacterial communication syst…
