The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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 ()…
The oral epithelium is essential for maintaining oral health and plays a key role in the onset and progression of periodontitis. It serves as both a mechanical and immunological barrier and possesses antimicrobial activity. Vitamin D, a hormone with…
BACKGROUND: Periodontitis is a chronic immune-inflammatory disease influenced by multiple factors. LL-37, an antimicrobial peptide, contributes to host defense, immune regulation, and tissue repair. Its subgingival expression following nonsurgical pe…
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…
OBJECTIVES: Rosacea is a chronic inflammatory disease that severely affects the quality of life of patients. Intense pulsed light (IPL) has been widely used in treating the erythema and telangiectasia in rosacea patients. However, the mechanism of it…
, a prominent genus in thefamily, has generated significant research attention due to its demonstrated biological potential, particularly its notable anti-inflammatory and antioxidant activities. In this study, two fractions of fermentedpolysaccharid…
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…
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 increase in bacterial resistance to minocycline and other tetracyclines poses a serious threat to global public health. Because the development of new antibiotics has proven problematic, antibiotic sensitization therapy is now an effective coping…
INTRODUCTION: Biologically active vitamin D (1,25-dihydroxyvitamin D or 1,25D) has emerged as a key regulator of human innate immunity. 1,25D signaling in macrophages strongly induces the expression of neutrophil chemoattractants, such as IL-8/CXCL8.…
Human cathelicidin LL-37 offers significant benefits to the immune system and in treating various diseases, but its therapeutic potential is hindered by low activity and instability in physiological environments. Here, we introduce a strategy to boos…
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…
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…
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis (Mtb) and is a growing public health problem worldwide. Within the innate immune response, we highlight the secretion of the antimicrobial peptide LL-37, which is crucial for…
BACKGROUND: Ruminants possess a rich repository of natural antimicrobial peptides(AMPs) within their bodies, surpassing those found in humans and mice. These peptides, including Defensin, Cathelicidin, and Lysozyme, are integral to the body's innate…
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…
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…
: 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…
BACKGROUND: Rosacea is a chronic inflammatory disease, and doxycycline is a widely recommended treatment for it due to its anti-inflammatory action. Oral isotretinoin reduces sebaceous gland activity and modulates toll-like receptors, reducing inflam…
Niclosamide is an oral anthelmintic agent and was reported to also have anti-inflammatory effects by suppressing STAT3 signaling pathways. In this study, we investigated the effect of niclosamide on skin inflammatory diseases to determine its potenti…
