The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
Owing to emerging global threats such as viral pandemics and the rise of antibiotic resistance, there is an urgent need for novel approaches to combat drug-resistant pathogens. Antimicrobial peptides (AMPs), also known as cationic host defense peptid…
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…
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…
Chronic wounds are life-threatening conditions characterized by impaired closure. Chronic inflammation and impaired regeneration and repair lead to the pathological phenotype of chronic diabetic wounds and reduce drug efficacy. In this study, we foun…
OBJECTIVE: This study aimed to systematically elucidate, for the first time, the therapeutic mechanism of Cuochuangling pills, (CCLP), a clinical herbal formulation for rosacea, through an innovative integrated approach combining network pharmacology…
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…
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…
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…
BACKGROUND: Fluorescence photobiomodulation (FPB) is a treatment for canine dermatitis, yet no studies exist assessing its effect on canine keratinocytes in vitro. OBJECTIVES: To determine: (i) the anti-inflammatory and antimicrobial effect of FPB on…
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…
Antimicrobial peptides (AMPs) are tiny proteins essential for innate immunity in various taxa, including mammals and insects. They provide defence against a wide range of pathogens, including bacteria, viruses, fungi, and parasites. Apart from their…
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…
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…
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…
Human mesenchymal stem cells (hMSCs) are versatile cells obtained from various regions of the human body. Beyond their potential for cell replacement, MSCs secrete a wide range of growth factors and cytokines and have recently been recognized for the…
The pathogenicity of Group A Streptococcus (GAS) is tightly regulated by the CovRS two-component system; however, the nature of the direct interaction between CovR and CovS, and how host signals modulate this system, remain poorly understood. Using s…
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…
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…
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…
