The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
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…
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…
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…
Bacterial extracellular vesicles (BEVs) serve as efficient drug-delivery vehicles for bioactive molecules including antimicrobial peptides (AMPs). In the present study, human cathelicidin-derived AMP LL37 was encapsulated in Streptococcus parauberis-…
Cathelicidins are evolutionarily conserved host defence peptides known for their dual antimicrobial and immunomodulatory functions. Among them, LL-37 in humans and CRAMP in rodents have emerged as crucial regulators of both mucosal immunity and CNS i…
The escalating global threat of antimicrobial resistance (AMR) and chronic biofilm-associated infections underscores the urgent need for novel therapeutic agents. Antimicrobial peptides (AMPs) offer a promising alternative due to their potent activit…
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…
GF-17, the main antimicrobial domain of LL-37, exhibits optimal amphipathicity and heightened hydrophobicity, leading to increased hemolytic activity. A series of novel GF-17-like antimicrobial peptides (AMPs) were designed using lysine scanning to e…
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…
: Bacterial biofilms formed bypose a significant challenge in veterinary medicine due to their intrinsic resistance to antibiotics. Antimicrobial peptides (AMPs) represent a promising alternative. AMPs exert their bactericidal activity by binding to…
Cathelicidin CATH-2 has been reported to exert potent anti-inflammatory activity in different species though neutralizing stimuli such as lipopolysaccharide (LPS) and lipoteichoic acid (LTA). CATH-2 has been shown to inhibit Streptococcus suis (S. su…
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…
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: Low back pain (LBP) is a debilitating condition with multifactorial etiology. Sagittal spinopelvic parameters play a crucial role in sagittal balance, and alterations lead to various spinal ailments, causing LBP. RATIONALE: This study aim…
Rosacea is a chronic inflammatory skin disease driven by oxidative stress and inflammation, yet it lacks effective treatments that simultaneously combine antioxidant and anti-inflammatory activities. This scarcity underscores the need for innovative…
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…
There is an urgent need for new antimicrobial agents to address the emerging antimicrobial resistance and the lack of novel antibiotics on the market. Antimicrobial peptides (AMPs) have gained significant interest as potential antibiotics over the pa…
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…
