The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Viral infectious diseases rank among the leading causes of mortality globally. The rise of drug resistance mechanisms puts the effectiveness of all existing antimicrobial drugs at risk, several of which have become ineffective. Consequently, there is…
Malaria control is challenged by the emergence of resistance to virtually all antimalarial drugs, from the frontline artemisinin to other classes, highlighting the critical need for new therapies. This study demonstrates that the human antimicrobial…
BACKGROUND: The growing threat of bacterial drug resistance compels researchers to pursue new therapeutic strategies. Finegoldia magna secretes SufA, a subtilisin- like protease that plays a critical role in virulence by degrading host defense molecu…
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…
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…
INTRODUCTION: Periodontitis is a plaque-induced condition that causes irreparable damage to the supporting tissues of the teeth, and tobacco smoking is a recognized exacerbating and risk factor. Antibiotic-resistant bacteria are a consequence of anti…
Urinary tract infections (UTIs) are the most common bacterial infections in women. During UTI, the host mounts a rapid immune response to clear the invading pathogen. Mast cells are tissue resident immune cells found in the bladder lamina propria and…
The increasing resistance and the pathogen's complex multi-drug resistance mechanisms made the selection of effective antimicrobial treatments more challenging for(). The study aimed to explore the effect of,and antimicrobial peptide LL-37 on the vir…
Klebsiella pneumoniae is one of the major pathogens responsible for multiple infections in clinical settings，and especially, the emergence of highly pathogenic variant known as hypervirulent K. pneumoniae (hvKp) poses an increasing threat to public h…
Bacterial keratitis is a potentially blinding corneal infection, withandbeing the leading gram-positive and gram-negative pathogens, respectively. The increasing antimicrobial resistance among these pathogens necessitates the development of newer the…
Protamine is a polybasic drug commonly used in cardiac surgery to chemically inhibit, and thereby reverse, the anticoagulant effect of heparin. However, protamine can trigger severe anaphylaxis, with both IgE-dependent and IgE-independent mechanisms…
() is a leading cause of human gastroenteritis worldwide and must overcome intestinal innate immunity, including antimicrobial peptide LL-37. However, howresponds to LL-37 remains unclear. Here, we showed thatinfection stimulates intestinal epithelia…
Multidrug-resistant Gram-negative pathogens pose a major global medical challenge due to the lack of new antibiotics. Outer membrane vesicles (OMVs) in Gram-negative bacteria significantly contribute to their resistance to antimicrobial peptides (AMP…
UNLABELLED: Atherosclerosis is the common underlying pathology in atherosclerotic cardiovascular disease (ASCVD) phenotypes of myocardial infarction (MI), stroke or peripheral artery disease (PAD). Single immune cell profiling of atherosclerotic plaq…
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…
The rise of antimicrobial resistance (AMR) has outpaced the development of new antibiotics, necessitating alternative therapeutic strategies that do not rely on conventional bactericidal approaches. Quorum-sensing (QS), a bacterial communication syst…

Antimicrobial resistance demands therapeutics that combine potent activity with low resistance potential. Ultrashort antimicrobial peptides (AMPs) are attractive due to their manufacturability and tunability, but activity is often lost upon sequence…
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…
Prevention and treatment of intramammary infections (IMI) associated with subclinical mastitis (SCM) are among the leading reasons for antimicrobial usage (AMU) in dairy cows, especially at dry-off. By adopting a selective dry cow therapy ((S)DCT), o…
