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…
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…
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…
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: Rosacea is a chronic inflammatory skin disease, with LL-37 driving inflammation. Inhibiting serine protease kallikrein-5 (KLK5) overactivity can reduce LL-37 production, thereby relieving this inflammation. Lithospermic acid (LA), a plant…
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…
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…
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…
BACKGROUND: Rosacea episcleritis, scleritis and uveitis may be missed when clinicians focus on the eye without appraising the adnexae and facial skin. Addressing rosacea can reduce treatment failures and avoid systemic complications of less effective…
Trichomoniasis is the most prevalent non-viral sexually transmitted infection worldwide and is caused by. The development of resistance against the standard treatment, metronidazole, highlights the need for alternative therapeutic approaches. The rol…
BACKGROUND: During the COVID-19 pandemic, it became evident that an infection with SARS-CoV-2 is associated with an increased predisposition for thrombembolic events. Recent studies suggest an excessive neutrophil extracellular trap (NET)-formation i…
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…
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…
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…
Periapical periodontitis (AP) is an inflammatory disease caused by persistent endodontic biofilms, and its treatment remains challenging because conventional root canal therapy sometimes fails to achieve effective disinfection and tissue regeneration…
Host defense peptides (HDPs), ancestral effectors of innate immunity, have emerged as pleiotropic regulators transcending their antimicrobial origins. This review critically examines the complex interplay among HDPs, hemostasis, and tissue repair. We…
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…
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…
Glycosylation represents a versatile strategy in peptide glycoengineering to modulate the structural, physicochemical, and biological properties of antimicrobial peptides (AMPs). In this study, we report the synthesis and characterization of O- and N…
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…
