The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Endogenous antimicrobial peptides (AMPs) derived from host proteins represent a largely underexplored class of natural products tied to innate immunity. Here, we investigated collagen proteins as a source of latent α-helical AMPs encoded within nonfi…
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…
Transient receptor potential vanilloid 4 (TRPV4) is a polymodal cation channel that is widely expressed in sensory neurons, immune cells, and structural tissues, where it integrates mechanical, osmotic, and chemical stimuli to regulate both physiolog…

The escalating global threat of antimicrobial resistance (AMR) and chronic biofilm-associated infections underscores the urgent need for novel therapeutic agents. Antimicrobial peptides (AMPs) offer a promising alternative due to their potent activit…
Urinary proteins offer multifaceted insights into tissue repair, dysfunction, and renal health, with significant implications for both human and veterinary medicine. However, marine mammal medicine lacks comprehensive studies on urine protein composi…
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,…
AIMS: This study examines the in vitro antibacterial activity of palatal adipose tissue-derived mesenchymal stem cells (PAT-MSCs) and the expression of antimicrobial peptide LL-37, with a particular focus on the effect of three-dimensional (3D) nanof…
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…
While probiotics are increasingly consumed for health benefits, comprehensive safety assessments, particularly for novel strains, are imperative. This study aimed to conduct a holistic safety and efficacy assessment of Bifidobacterium longum subsp. i…
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…
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…
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…
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…
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…
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…
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…
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…
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…
