Despite causing fatal encephalitis and long-term neurological, cognitive, and behavioral impairments in survivors, no antiviral drugs are currently available to treat Japanese encephalitis virus (JEV) infections, highlighting the urgent need for effe…

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…

INTRODUCTION: Antimicrobial peptides (AMPs) hold promises to counter antimicrobial resistance. They cause several deleterious effects in bacterial cells by interfering with cell wall biosynthesis, DNA replication, transcription, and translation. OBJE…

Inflammatory bowel disease (IBD) represents a chronic relapsing disorder driven by a loss of homeostatic balance between the host immune system and the intestinal microbiota. Endogenous antimicrobial peptides (AMPs), produced primarily by epithelial…

The double cooperative effect between two major antimicrobial peptides, LL-37 and HNP1, where their combination enhances antimicrobial efficiency while reducing cytotoxicity, offers a promising strategy for developing safer and more effective antibio…

BACKGROUND: Immune system is regulated by circadian rhythms, which promote inflammation and facilitate pathogen elimination. Antimicrobial peptides secreted by milk somatic cells and mammary gland epithelial cells play a crucial role in protecting th…

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…

INTRODUCTION: Activated polymorphonuclear neutrophils (PMN) release neutrophil extracellular traps (NETs) composed of a web-like DNA core, concomitant with nuclear histones, granular peptides and enzymes. NETs in human urine and their potential role…

Cancer cell migration is a key step in the metastatic cascade. Understanding its mechanisms represents one of the greatest challenges in modern oncology. Both in vitro and in vivo experimental models and mathematical descriptions of movement dynamics…

BACKGROUND: Visceral fat (VF), particularly epicardial adipose tissue (EAT), plays a crucial role in the development of coronary artery disease (CAD). Cathelicidin (LL37) is an antimicrobial peptide involved in innate immunity and has been implicated…

Prevention and treatment of intramammary infections (IMI) associated with subclinical mastitis (SCM) are among the leading reasons for antimicrobial usage (AMU) in dairy cows, especially at dry-off. By adopting a selective dry cow therapy ((S)DCT), o…

The appearance of antibiotic-resistant strains of() is leading to a decreased eradication rate ofinfection. There is an urgent need to find new agents with antimicrobial mechanisms different from those of antibiotics, with therapeutic potential to cl…

Transient receptor potential vanilloid 4 (TRPV4) is a polymodal cation channel that is widely expressed in sensory neurons, immune cells, and structural tissues, where it integrates mechanical, osmotic, and chemical stimuli to regulate both physiolog…

Urinary tract infections (UTIs) are the most common bacterial infections in women. During UTI, the host mounts a rapid immune response to clear the invading pathogen. Mast cells are tissue resident immune cells found in the bladder lamina propria and…

Synergistic bactericidal effects between antimicrobial peptides (AMPs) have been widely studied, yet their cooperative roles in reducing host-cell cytotoxicity remain poorly understood. Inspired by the cross-seeding observed in α-synuclein and β-amyl…

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…

INTRODUCTION: Rosacea is a persistent inflammatory dermatosis with a multifactorial etiology that significantly impairs patients' daily life and wellbeing. Vicenin-2, a natural flavonoid, has shown anti-inflammatory potential; however, its therapeuti…

BACKGROUND: To investigate key genes and immune microenvironment dynamics in cervical cancer progression and radiochemotherapy (RCT), focusing on cathelicidin antimicrobial peptide (CAMP)-mediated neutrophil regulation. METHODS: Integrated transcript…

Antimicrobial resistance significantly contributes to treatment failures in bacterial infections and poses a major global public health challenge, urgently necessitating the development of new antimicrobial agents, such as antimicrobial peptides (AMP…
