BACKGROUND: Previous studies have shown that bioactive molecules secreted by toad skin possess anticancer properties. Cathelicidin-DM (C-DM) is a bioactive peptide secreted by toad skin, but its effects on tumor cells and the underlying molecular mec…
INTRODUCTION: is a major human nosocomial infectious agent and an important veterinary pathogen, frequently resistant to various antibiotics. It causes diseases such as pneumonia, urinary tract infections, surgical wound infections and septicemia. Bi…
BACKGROUND: It is well recognized that developing new animal models, refining the existing mouse models, and thoroughly characterizing their features are essential for gaining a deeper understanding of rosacea pathogenesis and for advancing therapeut…
This review highlights the author's research conducted at Mukogawa Women's University from April 2002 to March 2024. The work is categorized into following three areas: (1) Evaluation of the bitterness of oral medications using a taste sensor, (2) De…
The antimicrobial effect of antimicrobial peptides is typically slow; they can be rapidly biodegraded and often have non-selective toxicity and elaborate sequences. Here we report a short peptide that is activated by ultrasound, that shows high broad…
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…
Tuberculosis (TB), primarily caused by, remains a global health burden. Current antibiotic treatments are limited by adverse effects, poor adherence, and drug resistance, necessitating new therapeutic approaches. Recent studies highlight the role of…
Wound dressings, integrated with nanotechnology, have garnered considerable attention recently due to their ability to synergistically combine antimicrobial efficacy with wound healing properties, while also supporting adherence to standardized wound…
PURPOSE: To study the angiogenic capacity of antimicrobial peptide LL37 (cathelicidin antimicrobial peptide), explore its molecular mechanisms, and provide new ideas for treating lower limb ischemic diseases. METHODS: LL37 was applied exogenously to…
Burn trauma triggers dysregulated systemic inflammation, leading to multiorgan dysfunction. Respiratory failure often follows burn injury, resulting in morbidity and mortality, in part, because of excessive and prolonged release of local and systemic…
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…
BACKGROUND: () is a gram-negative bacterial pathogen commonly associated with nosocomial infections. Treatment ofinfections is notoriously difficult due to biofilm formation and antibiotic resistance. Antimicrobial peptides (AMPs) are thought to be p…
Continual evolution of SARS-CoV-2 spike drives the emergence of Omicron variants that show increased spreading and immune evasion. Understanding how the variants orientate themselves towards host immune defence is crucial for controlling future pande…
This study develops a cobalt porphyrin-based hydrogen-bonded organic framework (Co-HOF) to scavenge reactive oxygen species (ROS) and target the pathogenic peptide LL-37, thereby disrupting psoriasis progression.
Antimicrobial peptides (AMPs) represent a promising class of therapeutics against bacterial pathogens. While their direct bactericidal mechanisms are well-characterized, how bacteria sense and respond to these peptides at sublethal concentrations rem…
BACKGROUND: Levels of the human cationic antimicrobial host defence peptide LL-37 are enhanced in the lungs during neutrophilic airway inflammation. LL-37 drives Th17 differentiation, and Th17 cells produce IL-17A and IL-17F which form the biological…
Deep skin fungal infections, particularly biofilm-associated(), pose significant clinical challenges due to their resistance to conventional antifungal therapies. The stratum corneum acts as a barrier to high molecular weight drugs, limiting the pene…
The human antimicrobial peptide LL-37 exhibits broad antimicrobial efficacy. However, it has several limitations including high production costs, reduced efficacy under physiological conditions, susceptibility to proteolytic degradation and significa…
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…
Cathelicidin 3 (CATHL3), a member of the cathelicidin family, exhibits potent resistance against a spectrum of microorganisms. Despite its importance, the expression pattern and regulatory mechanisms of CATHL3 in inflamed dairy mammary glands remain…
