The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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: The expression of transient receptor potential vanilloid (TRPV) and Toll-like receptor 2 (TLR2) in the lesion sites of patients with rosacea is increased. Ultraviolet B (UVB) radiation can induce inflammation of keratinocytes in patients…
Synergistic bactericidal effects between antimicrobial peptides (AMPs) have been widely studied, yet their cooperative roles in reducing host-cell cytotoxicity remain poorly understood. Inspired by the cross-seeding observed in α-synuclein and β-amyl…
Alzheimer's disease is mainly caused by two proteins, Tau and Amyloid-β. While there are several cures currently being explored for it, there is no cure yet for the disease progression and prevention, but only those to alleviate the symptoms. One of…
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…
The appearance of antibiotic-resistant strains of() is leading to a decreased eradication rate ofinfection. There is an urgent need to find new agents with antimicrobial mechanisms different from those of antibiotics, with therapeutic potential to cl…
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: Antimicrobial peptides are integral components of the innate immune system and play a vital role in maintaining oral homeostasis. LL-37, the only human cathelicidin antimicrobial peptide, has gained increasing attention due to its broad-s…
TLR-targeted immunotherapy represents a promising strategy for combating infectious diseases by initiating or enhancing protective antimicrobial immunity. Here, we identified the first frog-derived TLR2 and TLR4 agonist, Cathelicidin-Ka (Cath-Ka), fr…
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…
Immune cell populations are dysregulated in COVID-19 for currently unknown reasons: Plasmacytoid dendritic cell (pDC) populations are reduced, thus hampering antiviral responses. CD8T cell populations are reduced, the level of which has emerged as an…
BACKGROUND: Rosacea is a chronic inflammatory skin disease, with LL-37 driving inflammation. Inhibiting serine protease kallikrein-5 (KLK5) overactivity can reduce LL-37 production, thereby relieving this inflammation. Lithospermic acid (LA), a plant…
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…
The increasing prevalence of multidrug-resistant (MDR) bacterial infections poses global health challenges, highlighting the urgent need for new antimicrobial agents. The key advantages of antimicrobial peptides are their ability to rapid bactericida…
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…
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…
Due to the complex and variable microenvironment of wounds, bleeding and persistent infections have always posed significant challenges in wound treatment. Designing and developing therapeutic solutions with rapid hemostatic capabilities and antibact…
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…
1. This study investigated whether resveratrol (RES) can regulate the expression of duck cathelicidins (dCATHs) in heterophilic granulocytes (HGs). To address this, HG was isolated from ducks and treated with RES, followed by transcriptome sequencing…
