The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
Atherosclerosis (AS) is a prevalent clinical vascular condition and serves as a pivotal pathological foundation for cardiovascular diseases. Understanding the pathogenesis of AS has significant clinical and societal implications, aiding in the develo…
The Neisseria gonorrhoeae Type IV pilus is a dynamic fiber involved in host cell attachment, DNA transformation, twitching motility, and evading the innate immune system. We previously reported that pilus expression affects iron homeostasis and sensi…
AIMS: To investigate the effects of non-surgical periodontal treatment on the levels of cytokines, sIgA, antimicrobial peptides, oxidative and antioxidative agents in comparison between patients with and without diabetes. METHODS: A case-control stud…
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…
is a major cause of necrotizing enteritis in chickens. This study aimed to investigate the effects of zinc oxide quantum dots (ZnO-QDs) on growth performance, redox status, and gut microbiota in broilers challenged with. A total of 320 1-day-old chic…
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…
A vicious cycle between microbiota dysbiosis and hyperactivated inflammation, hardly disrupted by conventional therapies, remains a significant clinical challenge for periodontitis treatment. Herein, by cloaking a cascade catalysis system in an engin…
Poultry are susceptible to oxidative stress, which decreases immune function and negatively affects production performance under highly intensive feeding conditions. Moreover, anthocyanins can alleviate oxidative stress and improve immune functions i…
Sepsis-induced acute lung injury (ALI) is a serious disease constituting a heavy burden on society due to high mortality and morbidity. Inflammation and oxidative stress constitute key pathological mechanisms in ALI caused by sepsis. LL-37 can improv…
With antibiotic resistance being a major global concern, there is a huge need of new treatment options to fight bacterial infections. In this study, we highlight the antibacterial and host-protective roles of a novel synthetic antimicrobial peptide i…
BACKGROUND: Sputum extracellular DNA (eDNA) is associated with disease severity in asthma and COPD and therefore emerging as a potential therapeutic target. The aim of this study was to investigate the effect of 10 days of recombinant human DNase (rh…
Rosacea is a common chronic inflammatory skin disease that predominantly affects the central face. It can impair appearance and cause various discomforts, thus negatively impacting patients' physical and mental well-being as well as their quality of…
INTRODUCTION: Oral diseases such as caries and periodontitis are complex, multifactorial diseases and remain the most prevalent worldwide. Both diseases are associated with vitamin D deficiency (VDD) and its pathophysiological process. The prevalence…
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 development of anticancer peptides (ACPs) has emerged as a promising strategy in targeted cancer therapy due to their high specificity and therapeutic potential. Cathelicidin-derived antimicrobial peptides represent a particularly attractive clas…
Vitiligo is a pigmentary disorder acquired and caused by the loss or destruction of melanocytes from the epidermis. There is strong proof that vitiligo is mainly an autoimmune disease. Cathelicidin (LL37), an antimicrobial polypeptide, is an importan…
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…
Lytic transglycosylase A in Neisseria gonorrhoeae cleaves the β-1,4-glycosidic bond between peptidoglycan (PG) monomers to liberate 1,6-anhydro-PG fragments that are either recycled or released as cytotoxic fragments. To gain further insight into the…
Antimicrobial peptides (AMPs) can rapidly kill bacteria via disrupting the integrity of the cytoplasmic membrane. Although the understanding of the interaction between AMPs and phospholipid membrane is essential for related drug designs, theobservati…
