The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
BACKGROUND: The expression of transient receptor potential vanilloid (TRPV) and Toll-like receptor 2 (TLR2) in the lesion sites of patients with rosacea is increased. Ultraviolet B (UVB) radiation can induce inflammation of keratinocytes in patients…
BACKGROUND: Respiratory, gastrointestinal, and allergic diseases can significantly affect children's physical and mental health and quality of life. PURPOSE: This study aimed to assess the safety of Bifidobacterium animalis subsp. lactis BLa80, its p…
Cross-α amyloids are an emerging class of functional peptide assemblies that underlie biofilm formation and antibiotic resistance in bacteria. Beyond their biological significance, synthetic cross-α architectures exhibit remarkable rigidity and piezo…
This study presents a comprehensive multidimensional assessment of the safety and functional efficacy of Limosilactobacillus fermentum LF61, a strain isolated from human milk. Genomic analysis revealed no virulence factors (VFDB), drug resistance gen…
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…
The fever response is triggered during infection and inflammation, but the importance of this response for the function of antimicrobial peptides (AMPs) remains unknown. We discovered that the activity of the human AMP LL-37 is temperature-dependent…
BACKGROUND: Although caries is known to be influenced by diet and oral hygiene factors, susceptibility to the disease may be reduced by host factors, such as saliva antimicrobial peptides (AMPs). However, the relationship between salivary AMPs and ea…
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…
The growing global threat of antimicrobial resistance (AMR), particularly in cutaneous wound infections, represents a significant clinical and economic challenge. Biofilm formation by multidrug-resistant pathogens, such as, often complicates healing…
Dysregulation of low-density lipoprotein (LDL) cholesterol is strongly correlated with the risk of metabolic dysfunction-associated steatotic liver disease. Endogenous molecules targeting LDL clearance play crucial roles in the progression of liver s…
Lung metastasis is a leading cause of breast cancer (BC)-related mortality, driven by the immunosuppressive traits of the metastatic tumor microenvironment. However, the mechanisms underlying cell-cell crosstalk in shaping immune evasion within the m…
OBJECTIVE: This study aimed to elucidate the molecular mechanisms through which CXCL2 contributes to the pathogenesis of idiopathic interstitial pneumonia (IIP). METHODS: Neutrophils were isolated, and the formation of neutrophil extracellular traps…
Cathelicidins are crucial antimicrobial peptides (AMPs) that play a key role in the innate immunity of marine vertebrates. The pygmy sperm whale (Kogia breviceps), which resides in environments populated by diverse microbial communities, faces comple…
The human antimicrobial peptide LL-37 exerts a dual role in cancer, promoting tumor progression in breast carcinoma by stimulating calcium influx and enhancing cell migration. Its interactions with glycosaminoglycans (GAGs) provide an attractive ther…
Periodontitis, a multifactorial inflammatory disease driven by microbial dysbiosis, dysregulated immunity, and oxidative stress, demands therapeutic strategies that concurrently address interconnected pathological pathways. Here, a biomimetic lipid d…
Toxoplasmosis, a disease caused by apicomplexan, is associated with various neuropsychiatric and behavioral conditions. Toxoplasmosis can cause serious complications for those with weakened immune systems and during pregnancy. Cathelicidins, peptides…
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…
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…
Antimicrobial resistance (AMR) undermines the effectiveness of antibiotic treatment, and due to this, it now worldwide health concern. In general, antibiotics are used to control or combat bacteria, their widespread and irresponsible has contributed…
