The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
BACKGROUND: It is well recognized that developing new animal models, refining the existing mouse models, and thoroughly characterizing their features are essential for gaining a deeper understanding of rosacea pathogenesis and for advancing therapeut…
Non-canonical functions of olfactory receptors, one of the largest families of GPCR receptors not confined to the olfactory system, include an intriguing role on hair physiology. Previous studies using odorant agonists of the Olfactory Receptor famil…
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…
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…
Endometritis is a common reproductive disorder in dairy cows, with antibiotics being the primary treatment option. However, the overuse of antibiotics has contributed to the growing problem of antimicrobial resistance. Antimicrobial peptides (AMPs) h…
BACKGROUND: The role of vitamin D in Coronavirus Disease 2019 (COVID-19) outcomes remains debated, but emerging evidence suggests it may enhance recovery by strengthening immune responses. Vitamin D upregulates LL-37, an antimicrobial peptide with br…
The human cathelicidin peptide LL-37 induces autophagy in human macrophages. Different post-translational modifications (PTMs) such as citrullination, acetylation, and formylation impact LL-37, yet their effect on autophagy remains unknown. Thus, we…
Ferroptosis is an important cause of cardiomyocyte loss and cardiac dysfunction. Cathelicidin-related antimicrobial peptide (CRAMP) is an endogenous polypeptide that regulates oxidative stress in the body and is involved in ferroptosis. However, its…
Respiratory viral infections are a major contributor to mortality in children under 5 years of age, and disproportionately affect preterm neonates. Previously, using our established 3-day-old neonatal murine model of influenza virus infection, we dem…
BACKGROUND: Activation of the aryl hydrocarbon receptor (AhR) ameliorates LL-37-induced rosacea-like dermatitis in mice, whereas mast cells and cytokine overexpression are prominent features in rosacea skin. OBJECTIVE: To evaluate the potential mecha…
The aberrant aggregation of the human islet amyloid polypeptide (hIAPP) is a hallmark of type II diabetes. LL37, the only cathelicidin host-defense peptide in humans, plays essential roles in antimicrobial and immunomodulatory activities. Mounting ev…
The bidirectional correlation between diabetes and periodontitis positions the latter as the most prevalent complication of the former. Rehabilitation of the periodontal tissues damaged by diabetic periodontitis presents a significant clinical challe…
Antimicrobial peptides (AMPs) represent a promising class of therapeutics against bacterial pathogens. While their direct bactericidal mechanisms are well-characterized, how bacteria sense and respond to these peptides at sublethal concentrations rem…
The human antimicrobial peptide LL-37 exhibits broad antimicrobial efficacy. However, it has several limitations including high production costs, reduced efficacy under physiological conditions, susceptibility to proteolytic degradation and significa…
BACKGROUND: Wound healing is a complex and regulated process that involves the coordinated action of key signaling pathways. Activating transcription factor 3 (ATF3) is a stress-inducible protein that has recently emerged as a critical modulator of c…
Antimicrobial peptides (AMPs) have the potential to treat multidrug-resistant bacterial infections. Cathelicidins are a class of cationic antimicrobial peptides that are found in nearly all vertebrates. Herein, we determined the mature peptide region…
This paper strove to characterize and compare ejaculates collected from two geese breeds over the period of two years in the context of selected traditional, biochemical, oxidative, bacteriological, and immunological properties. Slovak white and Such…
Inflammatory bowel diseases (IBDs) are chronic disorders affecting the gastrointestinal tract, causing severe inflammation and tissue damage. Current treatments often have adverse effects, underscoring the need for alternatives. This article is a sho…
Herpes simplex virus type 1 (HSV-1) is a globally prevalent pathogen that can infect a variety of animal species as well as humans. However, existing antiviral therapies are constrained in their capacity to effectively target viral latency and preven…
