The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Antimicrobial peptides (AMPs), such as cathelicidins, show dual functionality by directly combating pathogens and indirectly eliminating them through stimulation of the immune system, generating interest in their therapeutic potential. Pigs have a la…
Antimicrobial peptides (AMPs) play a crucial role in immune defense and wound healing. Their expression and function in pleural fluids following different thoracic surgeries remain underexplored. This study aims to compare AMP and cytokine profiles i…
OBJECTIVE: Gut microbiota dysbiosis induced by antibiotic use weakens its colonization resistance against opportunistic pathogens, increasing the risk of invasion and infection. While probiotics have the potential to restore the impaired gut microbia…
The antimicrobial effect of antimicrobial peptides is typically slow; they can be rapidly biodegraded and often have non-selective toxicity and elaborate sequences. Here we report a short peptide that is activated by ultrasound, that shows high broad…
BACKGROUND: Previous studies have shown that bioactive molecules secreted by toad skin possess anticancer properties. Cathelicidin-DM (C-DM) is a bioactive peptide secreted by toad skin, but its effects on tumor cells and the underlying molecular mec…
Lacticaseibacillus paracasei cell wall presents two capsular polysaccharides, CPS-1 and CPS-2, and a teichoic acid. CPS-1 is novel and it presents a branched heptasaccharide repeating unit, with the sequence →6)-α-d-Gal-(1→3)-β-l-Rha-(1→4)-β-d-Glc-(1…
Tuberculosis (TB), caused by(MTB), remains one of the most devastating infectious diseases worldwide, with rising multidrug resistance limiting the effectiveness of conventional treatments. Novel therapeutic approaches are urgently needed to compleme…
Cathelicidin-DM and cathelicidin-BG are homologous and are expected to be similar in structure and biological activity. However, while all structural prediction tools tested showed cathelicidin-BG to be helical, there were mixed results for cathelici…
INTRODUCTION: is a major human nosocomial infectious agent and an important veterinary pathogen, frequently resistant to various antibiotics. It causes diseases such as pneumonia, urinary tract infections, surgical wound infections and septicemia. Bi…
Bacteriophages are the dominant members of the human enteric virome and can shape bacterial communities in the gut; however, our understanding of how they directly impact health and disease is limited. Previous studies have shown that specific bacter…
Biomarkers are necessary tools to validate the diagnosis of Alzheimer's and Parkinson's diseases (AD and PD), especially when clinical symptoms are less apparent in the early stages of diseases. Current biomarkers used in clinical practice rely on br…
Helminths can manipulate their host's gut microbiota, with the expansion of the lactobacilli population being a common feature. This process profoundly influences host immunoregulation, yet the underlying mechanisms remain almost unknown. Using a tis…
Rosacea is a chronic inflammatory skin disease and is usually accompanied by extensive macrophage infiltration. There is growing evidence suggesting that neurotransmitter 5-hydroxytryptamine (5-HT) plays a crucial role in inflammatory reactions. Howe…
INTRODUCTION: The constantly growing resistance of bacteria causing bloodstream infections and the lack of alternative antibiotics generate the need to develop new therapeutic strategies. In this study, the antibacterial properties of synthetic choli…
Rosacea is a chronic inflammatory skin disease primarily affecting the central region of the face. Typical manifestations include erythema, papules, or pustules on the cheeks, glabella, chin, and nose, with some patients experiencing ocular involveme…
Cathelicidin 3 (CATHL3), a member of the cathelicidin family, exhibits potent resistance against a spectrum of microorganisms. Despite its importance, the expression pattern and regulatory mechanisms of CATHL3 in inflamed dairy mammary glands remain…
Rosacea is a chronic inflammatory skin disorder linked to the antimicrobial peptide LL-37 and immune cells. STING, a key DNA-sensing adaptor, initiates innate immune responses, with excessive activation contributing to inflammation. This study invest…
Bacterial extracellular vesicles (BEVs) have emerged as a promising therapeutic platform, offering the potential to be engineered for targeted molecular delivery. In this study, the human cathelicidin antimicrobial peptide (LL37) was encapsulated int…
OBJECTIVE: To assess the feasibility of gene expression profiling of platelets in dogs with sepsis. METHODS: This was a prospective observational feasibility study conducted at a university veterinary teaching hospital. All study dogs had CBCs and se…
Chronic spontaneous urticaria (CSU) is a significant clinical condition characterized by an undetermined etiology, with some of its manifestations being attributed to immunological factors. The antibacterial properties of the cathelicidin leucine-leu…
