The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
INTRODUCTION: Rosacea is a chronic inflammatory skin disorder characterized by symptoms like itching, redness, and impaired skin barrier function. Mast cell activation plays a crucial role in its pathogenesis. Recent evidence shows higher expression…
Rosacea is a chronic inflammatory disease characterised by facial erythema, telangiectasia, papules, pustules, and ocular manifestations. Mas-related G protein-coupled receptor X2 (MRGPRX2), suggested as a key receptor in the pathogenesis and inflamm…
BACKGROUND AND AIMS: Vitamin D deficiency, widely prevalent in patients with chronic kidney disease (CKD) could play a role in the pathogenesis of cardiovascular disease (CVD) by causing alterations in endothelial and immune function. We investigated…
BACKGROUND: Levels of the human cationic antimicrobial host defence peptide LL-37 are enhanced in the lungs during neutrophilic airway inflammation. LL-37 drives Th17 differentiation, and Th17 cells produce IL-17A and IL-17F which form the biological…
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…
Characterising functional diversity is a vital element to understanding a species' immune function, yet many immunogenetic studies in non-model organisms tend to focus on only one or two gene families such as the major histocompatibility complex (MHC…
Chronic hypoxia events are a common occurrence in Atlantic salmon () sea-cages, especially during the summer, and their frequency and severity are predicted to increase with climate change. Although hypoxia is considered a very important fish health…
Marsupial neonates are born with immature immune systems, making them vulnerable to pathogens. While neonates receive maternal protection, they can also independently combat pathogens, although the mechanisms remain unknown. Using the sugar glider ()…
Colonic goblet cells play a crucial role in mucosal defense by secreting Muc2 mucin and other proteins that entrap and expel enteropathogens. However, the role of innate effectors in the gut like cathelicidin peptides in regulating the mucus barrier…
BACKGROUND: Pulmonary infections with multidrug-resistant nontuberculous mycobacteria (NTM), particularly Mycobacterium abscessus (MAB), are increasingly more prevalent in individuals with lung disease such as cystic fibrosis and are extremely diffic…
The escalating threat of antibiotic resistance demands novel antimicrobial strategies. This study introduces PCR12mod6, a rationally designed peptide derived from the amphibiancathelicidin-HR, engineered for both antimicrobial and antioxidant functio…
Urinary tract infections (UTIs) are common in children and are predominantly caused by uropathogenic(UPEC). An increasing proportion of these strains produce extended-spectrum β-lactamases (ESBLs), which render β-lactam antibiotics ineffective. Inter…
BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory disorder characterised by the formation of non-caseating granulomas in breast tissue, primarily affecting young women of childbearing age. The aetiology of IGM remains uncl…
: Excessive body fatness is the basis of many diseases, especially civilization-related ones. The aim of this study is to analyze the body composition and serum levels of selected antimicrobial peptides (AMPs) in patients with basal cell carcinoma (B…
Antimicrobial peptides (AMPs) are natural molecules of great interest in the fight against bacteria and in addressing antibiotic resistance. Their use as antimicrobial drugs is still limited due to their cytotoxicity and poor resistance to proteolysi…
Candidiasis belongs to common fungal infections and is usually mild and self-limiting. However, in patients with immunodeficiencies, it can transform into invasive infections with high mortality. Long-term antifungal treatment can lead to the emergen…
AIMS: This study aims to develop novel antibacterial agents by targeting SufA protease, a key virulence factor in Finegoldia magna, using 1-aminoalkylphosphonate (1-AAP) diaryl esters as inhibitors. MATERIALS & METHODS: Structural optimization of a r…
Klebsiella pneumoniae is becoming increasingly difficult to treat as multidrug-resistant (MDR) strains become more prevalent. The formation of biofilm heightens this threat by embedding bacterial cells in a polysaccharide-rich matrix that limits anti…
OBJECTIVE AND DESIGN: We aimed to investigate potential lymphatic vessel abnormalities associated with rosacea and elucidate effective rosacea treatment mechanism using long-pulsed 1064-nm neodymium: yttrium-aluminum-garnet laser (LPND). MATERIAL OR…
Infections with the protozoancause abortion in cattle, likely due to the parasite's replication and excessive inflammation in the placenta. Cathelicidins are host defense peptides known for their antimicrobial and immunomodulatory functions, but thei…
