The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
INTRODUCTION: Antimicrobial resistance in bacterial and fungal pathogens poses a major threat to global health, withrecently classified by the WHO as a critical priority pathogen. Antimicrobial peptides (AMPs) have emerged as promising candidates due…
Alcohol exposure affects immune regulation and tissue homeostasis. Antimicrobial peptides (AMPs) are essential components of innate immunity, not only defending against pathogens but also modulating processes such as inflammation. However, their tiss…
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…
BACKGROUND: Alterations of epithelial barrier integrity and immune response play a key role in the pathogenesis of allergic diseases and represent promising targets for nutritional interventions. Selected postbiotics and plant-derived compounds have…
INTRODUCTION: Adipose-derived mesenchymal stem cells (ADSCs) have been widely investigated for their pro-angiogenic and immunomodulatory roles in the repair of infected wounds. However, the direct antimicrobial effects of ADSCs and the underlying reg…
Antimicrobial peptides (AMPs) are promising agents against infections caused by multidrug-resistant bacteria. Notably, the human AMPs LL-37 and α-defensin (HNP1) exhibit a cooperative effect, synergistically killing bacteria while reducing host cytot…
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…
BACKGROUND: Carotid plaque vulnerability is a current feature that aids in the decision-making for ischemic stroke risk. Proteomic analysis of plaque tissue can reveal molecular indicators of instability that complement imaging findings. We sought to…
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…
S protein is conserved among streptococci and contributes to group A Streptococcus virulence, but the mechanisms involved are unclear. Here we used genetic, biochemical, single-molecule, in vitro and in vivo analyses to show that S protein is crucial…
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…
PURPOSE: This study aimed to examine the acute effects of continuous and interval cycling on salivary secretory immunoglobulin A (SIgA) and anti-microbial peptides. METHODS: In a randomized crossover trial, 12 healthy young untrained men (22 ± 1 year…
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: Dental plaque is a highly organized polymicrobial biofilm, in which extracellular DNA serves as a vital structural and functional component of the extracellular matrix. The human antimicrobial peptide LL-37 plays an important role in oral…
OBJECTIVES: The increasing prevalence of antibiotic-resistant Salmonella Typhimurium has highlighted the urgent need for alternative therapeutic strategies. This study engineered a lytic S. Typhimurium bacteriophage to present the antimicrobial pepti…
Vitamin D is a secosteroid hormone traditionally recognized for its role in bone and mineral metabolism, but it is increasingly understood to also function as an important immunomodulator influencing susceptibility to and outcomes of infectious disea…
BACKGROUND: Dysbiotic oral biofilms produce virulence factors, such as lipopolysaccharide (LPS), triggering and sustaining chronic inflammation in periodontal tissues. Modulation of the bioactivity of these products offers a potential novel, adjuncti…
is a notorious opportunistic pathogen that causes life-threatening infections in immunocompromised individuals. In this study, we isolated two mucoid imipenem-resistantstrains, SCPa14 and SCPa16, from a single silicosis patient. Whole-genome sequenci…
Extensive research has investigated the therapeutic potential of mesenchymal stem cells (MSCs) in treating infectious diseases and mitigating tissue damage caused by these diseases. MSCs, along with their exosomes, present a promising avenue for comb…
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…
