The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
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…
BBi32, isolated from a healthy infant, underwent a multi-tiered safety assessment to evaluate its genetic features, in vitro properties, and effects on gut microbiota and host biomarkers. Whole-genome sequencing (WGS) and functional annotation were p…
Chronic diabetic wounds do not heal and are often accompanied by infections and poor angiogenesis. We have made a two-layered PVA/CS composite hydrogel MN-CL patch, which has antibacterial, immunoregulatory, and pro-healing properties. The needle tip…
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…
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…
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…
Mastitis is a major cause of economic losses in dairy production; however, its prevention and treatment remain challenging. Under field conditions, antimicrobial drugs are frequently administered when somatic cell counts (SCCs) are elevated and signs…
Lung metastasis is a leading cause of breast cancer (BC)-related mortality, driven by the immunosuppressive traits of the metastatic tumor microenvironment. However, the mechanisms underlying cell-cell crosstalk in shaping immune evasion within the m…
The etiology of Alzheimer's disease (AD) remains under active debate. In this perspective, we explore the hypothesis that a primarily infection-caused chronic dysregulation and weakening of human innate immunity via the underexpression, degradation,…
OBJECTIVE: This study aimed to systematically elucidate, for the first time, the therapeutic mechanism of Cuochuangling pills, (CCLP), a clinical herbal formulation for rosacea, through an innovative integrated approach combining network pharmacology…
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…

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…
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…
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…
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…
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…
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…
