The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
INTRODUCTION: Elevated levels of serum Vitamin D (VitD) and increased expression of its receptor on peripheral blood cells have been reported in individuals who have been exposed to HIV-1 yet remain seronegative (HESN). This study aimed to investigat…
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…
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…
BACKGROUND: Reinfection in the root canal and periradicular area due to the emergence of antibiotic resistance and/or multidrug-resistant strains of mixed colonization of multispecies periapical endodontic is the main reason for endodontic treatment…
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…
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…
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…
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…
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…
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…
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,…
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…

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…
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…
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…
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…
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 double cooperative effect between two major antimicrobial peptides, LL-37 and HNP1, where their combination enhances antimicrobial efficiency while reducing cytotoxicity, offers a promising strategy for developing safer and more effective antibio…
