The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
BACKGROUND: Diabetic urinary incontinence is a multifactorial condition involving neuropathy, oxidative stress, and epithelial dysfunction. Serum biomarkers-cathelicidin (LL-37), elafin, vitamin D receptor (VDR), 4-hydroxynonenal (4-HNE), and amyloid…
The increasing threat of bacterial drug resistance calls for effective solutions, and antimicrobial peptides (AMPs) hold great promise. However, the connection between their structure and function remains unclear. The study of the structure-function…
Lytic transglycosylase A in Neisseria gonorrhoeae cleaves the β-1,4-glycosidic bond between peptidoglycan (PG) monomers to liberate 1,6-anhydro-PG fragments that are either recycled or released as cytotoxic fragments. To gain further insight into the…
LL-37 and its variants with amphiphilic structure can modulate amyloid-β (Aβ) fibril formation, but the detailed mechanism behind it is still unclear. By using four different peptides (LL-37, LL-37, LL-37, LL-37), we found these peptides affect Aβ40…
Cathelicidin LL-37, an antimicrobial peptide (AMP) of the innate immune system, wards off bacterial infections. Recent research has identified plenty of biological functions of AMPs beyond their antimicrobial activity, including antioxidant, self-ren…
Cathelicidins are a family of antimicrobial peptides (AMPs) with broad-spectrum activity and immunomodulatory functions. Among them, the only human cathelicidin LL-37 has garnered significant interest due to its potent antimicrobial, antiviral, antif…
BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of endovascular infections. The prophage-encoded protein Gp05 has been identified as a critical virulence factor that contributes to MRSA persistence during vancomycin…
BACKGROUND: Numerous studies have shown the presence of multiple defence factors in placental tissue, although their role is partially understood; therefore, the aim of this study was to evaluate the expression of nuclear factor-kappa B (NF-κB); huma…
The development of anticancer peptides (ACPs) has emerged as a promising strategy in targeted cancer therapy due to their high specificity and therapeutic potential. Cathelicidin-derived antimicrobial peptides represent a particularly attractive clas…
BACKGROUND: Information about the association of antimicrobial peptides with hypovitaminosis D in hospitalized foals is lacking. HYPOTHESIS/OBJECTIVES: We aimed to longitudinally determine the association of serum concentrations of vitamin D metaboli…
Respiratory syncytial virus (RSV) plays a major part in causing lower respiratory tract infections in younger populations, especially in infants and pediatric patients, causing a higher rate of morbidity and mortality in the respective population, af…
The bacterial oral environment poses a significant challenge to the long-term stability of dental implants due to vulnerability of peri-implant soft tissues to pathogenic infiltration. Therefore, the rapid formation of a dense soft tissue barrier in…
This study aims to investigate the effect of different levels of zinc oxide quantum dots (ZnO-QDs) on the growth performance and gut health in broilers. A total of 1125 1-day-old Ross 308 broilers were randomly divided into five groups with 15 replic…
Brachymystax lenok is an economically valuable cold-water fish species that has shown lower morbidity during pathogen outbreaks compared to other cold-water species. To elucidate the innate immune mechanisms in B. lenok in response to Aeromonas salmo…
BACKGROUND AND AIMS: Vitamin D deficiency, widely prevalent in patients with chronic kidney disease (CKD) could play a role in the pathogenesis of cardiovascular disease (CVD) by causing alterations in endothelial and immune function. We investigated…
INTRODUCTION: Rosacea is a chronic inflammatory skin disorder characterized by symptoms like itching, redness, and impaired skin barrier function. Mast cell activation plays a crucial role in its pathogenesis. Recent evidence shows higher expression…
Atherosclerosis (AS) is a prevalent clinical vascular condition and serves as a pivotal pathological foundation for cardiovascular diseases. Understanding the pathogenesis of AS has significant clinical and societal implications, aiding in the develo…
Cathelicidin-BF (CatBF) is a LL-37 homologous antimicrobial peptide (AMP) isolated fromwith an exceptional portfolio of antimicrobial, antiviral, antifungal, and anticancer activities. Contrary to many AMPs, it showed a good pharmacological profile w…
BACKGROUND: The genetic modification of mesenchymal stromal/stem cells (MSCs) to express antimicrobial peptides may provide a promising strategy for developing advanced cell-based therapies for bacterial infections, including those caused or complica…
BACKGROUND: 1,25(OH)Dsupplementation alone does not provide sufficient benefit to hepatocellular carcinoma (HCC) patients in clinical trials. Tumor-associated macrophages (TAMs)-mediated immunosuppression is regarded as a major hurdle for the effecti…
