The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
Alcohol exposure affects immune regulation and tissue homeostasis. Antimicrobial peptides (AMPs) are essential components of innate immunity, not only defending against pathogens but also modulating processes such as inflammation. However, their tiss…
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…
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…
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…
The increasing resistance and the pathogen's complex multi-drug resistance mechanisms made the selection of effective antimicrobial treatments more challenging for(). The study aimed to explore the effect of,and antimicrobial peptide LL-37 on the vir…
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…
BACKGROUND: The evidence of a low-biomass microbial community in the amniotic fluid (AF) is challenging the traditional concept of a sterile womb. To clarify microbial presence and host responses, a comprehensive, multi-methodological approach is req…
The human antimicrobial peptide LL-37 exerts a dual role in cancer, promoting tumor progression in breast carcinoma by stimulating calcium influx and enhancing cell migration. Its interactions with glycosaminoglycans (GAGs) provide an attractive ther…
BACKGROUND: Alterations of epithelial barrier integrity and immune response play a key role in the pathogenesis of allergic diseases and represent promising targets for nutritional interventions. Selected postbiotics and plant-derived compounds have…
BACKGROUND: ApoB (apolipoprotein B)-containing lipoproteins are causal risk factors for atherosclerotic coronary artery disease (CAD). Since human cathelicidin LL-37 binds to ApoB-100 in this pathological context, we investigated whether the circulat…
UNLABELLED: Atherosclerosis is the common underlying pathology in atherosclerotic cardiovascular disease (ASCVD) phenotypes of myocardial infarction (MI), stroke or peripheral artery disease (PAD). Single immune cell profiling of atherosclerotic plaq…
Cross-α amyloids are an emerging class of functional peptide assemblies that underlie biofilm formation and antibiotic resistance in bacteria. Beyond their biological significance, synthetic cross-α architectures exhibit remarkable rigidity and piezo…
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…
1. This study investigated whether resveratrol (RES) can regulate the expression of duck cathelicidins (dCATHs) in heterophilic granulocytes (HGs). To address this, HG was isolated from ducks and treated with RES, followed by transcriptome sequencing…
The host-defense peptide cathelicidin LL37 is an innate immune defense peptide with broad-spectrum antimicrobial effects. Experiments showed that the antimicrobial activity of LL37(17-29), the active core of LL37, was associated with peptide aggregat…
Multidrug-resistant Gram-negative pathogens pose a major global medical challenge due to the lack of new antibiotics. Outer membrane vesicles (OMVs) in Gram-negative bacteria significantly contribute to their resistance to antimicrobial peptides (AMP…
Rosacea is a chronic inflammatory disease of facial skin with unknown pathophysiology. Abnormal overexpression of human antimicrobial peptide LL-37 is a hallmark of rosacea. However, its significance in rosacea pathogenesis is not fully understood. W…
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…
Bacterial extracellular vesicles (BEVs) serve as efficient drug-delivery vehicles for bioactive molecules including antimicrobial peptides (AMPs). In the present study, human cathelicidin-derived AMP LL37 was encapsulated in Streptococcus parauberis-…
