The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
BACKGROUND: Pneumonia remains a leading cause of morbidity and mortality among children globally, especially in low- and middle-income countries, where poor nutrition and limited access to healthcare increase vulnerability. Vitamin D deficiency is co…
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…
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…
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…
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…
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…
Cathelicidins are evolutionarily conserved host defence peptides known for their dual antimicrobial and immunomodulatory functions. Among them, LL-37 in humans and CRAMP in rodents have emerged as crucial regulators of both mucosal immunity and CNS i…
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…
This study presents a comprehensive multidimensional assessment of the safety and functional efficacy of Limosilactobacillus fermentum LF61, a strain isolated from human milk. Genomic analysis revealed no virulence factors (VFDB), drug resistance gen…
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…
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…
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…
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…
The human cathelicidin host defense peptide LL-37 is expressed by many cell types, including neutrophils, macrophages, and epithelial cells, and forms complexes with nucleic acids that can have either beneficial or detrimental health effects. We sugg…
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…
INTRODUCTION: Urinary catheterization frequently causes urinary tract infections and patient discomfort. While hydrogel coatings combining antibacterial and hydrophilic properties offer a potential solution, challenges such as uncontrolled antimicrob…
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…
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…
