The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
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…
Lipid droplets (LDs) are lipid-rich organelles recognized as central players in lipid homeostasis, signaling, and inflammation. While their functions in inflammation are well-documented, the mechanisms of LDs in antibacterial immunity and infection r…
GF-17, the main antimicrobial domain of LL-37, exhibits optimal amphipathicity and heightened hydrophobicity, leading to increased hemolytic activity. A series of novel GF-17-like antimicrobial peptides (AMPs) were designed using lysine scanning to e…
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…
INTRODUCTION: Rosacea is a persistent inflammatory dermatosis with a multifactorial etiology that significantly impairs patients' daily life and wellbeing. Vicenin-2, a natural flavonoid, has shown anti-inflammatory potential; however, its therapeuti…
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…
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…
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…

Despite causing fatal encephalitis and long-term neurological, cognitive, and behavioral impairments in survivors, no antiviral drugs are currently available to treat Japanese encephalitis virus (JEV) infections, highlighting the urgent need for effe…
Antimicrobial peptides (AMPs) are promising agents against infections caused by multidrug-resistant bacteria. Notably, the human AMPs LL-37 and α-defensin (HNP1) exhibit a cooperative effect, synergistically killing bacteria while reducing host cytot…
Quercetin-loaded cellulose nanocrystals (QL-CNC) were developed as a reactive oxygen species (ROS)-responsive nanocarrier for the targeted treatment of rosacea. A murine model of rosacea-like dermatitis was induced using LL-37. The therapeutic effica…
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.…
: Bacterial biofilms formed bypose a significant challenge in veterinary medicine due to their intrinsic resistance to antibiotics. Antimicrobial peptides (AMPs) represent a promising alternative. AMPs exert their bactericidal activity by binding to…
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…
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…
BACKGROUND: Respiratory, gastrointestinal, and allergic diseases can significantly affect children's physical and mental health and quality of life. PURPOSE: This study aimed to assess the safety of Bifidobacterium animalis subsp. lactis BLa80, its p…
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…
