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…
Antimicrobial resistance demands therapeutics that combine potent activity with low resistance potential. Ultrashort antimicrobial peptides (AMPs) are attractive due to their manufacturability and tunability, but activity is often lost upon sequence…
Human cathelicidin peptide LL-37 is encoded by the CAMP gene and plays a key role in innate immunity. It maintains intestinal homeostasis through antibacterial, immunomodulation, and tissue repair functions. This paper reviews the multiple functions…
Klebsiella pneumoniae is one of the major pathogens responsible for multiple infections in clinical settings，and especially, the emergence of highly pathogenic variant known as hypervirulent K. pneumoniae (hvKp) poses an increasing threat to public h…
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…

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…
The emergence of drug resistance and host toxicity is associated with conventional antiprotozoal therapies which necessitates development of novel and selective antiparasitic agents. In the present study, novel hybrid peptide which is HP-AP-1 (KRIVQR…
Macrophage antimicrobial programs are regulated not only by transcriptional networks but also by RNA processing mechanisms affecting signal transduction and effector responses. One such mechanism, alternative polyadenylation (APA), determines mRNA fa…
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…
INTRODUCTION: Periodontitis is a plaque-induced condition that causes irreparable damage to the supporting tissues of the teeth, and tobacco smoking is a recognized exacerbating and risk factor. Antibiotic-resistant bacteria are a consequence of anti…
The limited selectivity of antimicrobial peptides (AMPs) can lead to unintended damage to healthy eukaryotic cells, a process strongly influenced by membrane physicochemical properties. Cholesterol (CHO) is a key regulator of lipid packing, membrane…
AIMS: This study examines the in vitro antibacterial activity of palatal adipose tissue-derived mesenchymal stem cells (PAT-MSCs) and the expression of antimicrobial peptide LL-37, with a particular focus on the effect of three-dimensional (3D) nanof…
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…
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…
BACKGROUND: Pseudomonas aeruginosa is a major cause of acute nosocomial infections, as well as chronic respiratory infections associated with cystic fibrosis (CF). In chronic lung infections, P. aeruginosa populations typically exhibit extensive phen…
Mastitis is a major cause of economic losses in dairy production; however, its prevention and treatment remain challenging. Under field conditions, antimicrobial drugs are frequently administered when somatic cell counts (SCCs) are elevated and signs…
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…
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…
