The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
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…
BACKGROUND: Recurrent urinary tract infection (rUTI) is a major diagnostic and management challenge. Dysregulated innate immune responses, including antimicrobial peptides and cytokines, may underlie UTI susceptibility. This study investigates whethe…
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 gastrointestinal tract hosts a diverse microbial community, named the intestinal microbiota, which plays a vital role in gut health. Host defense peptides (HDPs), such as defensins, help regulate interactions between the host and its microbiota.…
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…
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…
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…
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…
Owing to emerging global threats such as viral pandemics and the rise of antibiotic resistance, there is an urgent need for novel approaches to combat drug-resistant pathogens. Antimicrobial peptides (AMPs), also known as cationic host defense peptid…
BACKGROUND: During airway inflammation, chemokines, oxylipins (bioactive lipids) and cationic host defence peptides (CHDP) are enhanced in the lungs. However, the interplay of these molecules in the process of airway inflammation is not fully resolve…
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…
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…
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…
Bronchopulmonary dysplasia (BPD) is a chronic lung condition in preterm infants characterized by impaired alveolar development, disrupted vascular growth, and persistent inflammation. These alterations, which often arise from early exposure to mechan…
The human cathelicidin host defense peptide LL-37 forms complexes with nucleic acids that can have either beneficial or detrimental health effects. We suggest that these differential impacts are directly connected to dsDNA binding by LL-37 and to com…
To combat the growing challenge of bacterial infections, sonodynamic antibacterial technology has gained increasing attention. However, current approaches still face limitations, including suboptimal efficacy and a narrow antibacterial spectrum (only…
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…
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…
