The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
causes ocular and other infections and quickly acquires antimicrobial resistance. Polymyxin B and colistin are last-line agents against resistant, yet even resistance to these is increasing. Antimicrobial peptides (AMPs) are also being developed as n…
: 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…
Human adipose-derived stem cells (hADSCs) exhibit antibacterial properties, but their effectiveness against bacteria resistant to LL-37- a natural human antimicrobial peptide important in the immune defense- is not fully understood. Some bacteria hav…
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: Neisseria meningitidis asymptomatically colonizes the nasopharyngeal mucosa, but occasionally, the bacteria disseminate to cause sepsis and meningitis. In the epithelial cell layer, the pathogen co-colonizes with other resident inhabitant…
Cutaneous squamous cell carcinoma (cSCC) is a common skin cancer caused by mutagenesis resulting from excess UVR or other types of oxidative stress. These stressors also upregulate the production of a cutaneous innate immune element, cathelicidin ant…
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…
Cathelicidins are a family of proteins from which a class of Host Defence Peptides (HDPs) is derived. They are components of the innate immune system of most vertebrates, including birds. Despite their promising activities, the genomic organisation a…
The increasing threat of bacterial drug resistance calls for effective solutions, and antimicrobial peptides (AMPs) hold great promise. However, the connection between their structure and function remains unclear. The study of the structure-function…
STUDY DESIGN: A retrospective cohort study. OBJECTIVE: This study aimed to investigate the relationship between disruption of cartilage endplates and postoperative recurrence of lumber disk herniation (LDH) using preoperative T1-weighted magnetic res…
LL-37 is the sole member of the cathelicidin family of antimicrobial peptides in humans, primarily produced by phagocytic leukocytes and epithelial cells, mediating a wide range of biological responses. Discovered in human neutrophils, LL-37 is known…
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…
The human gut microbiome consists of diverse microbes that communicate through small molecules. Numerous recent studies have demonstrated links between gut microbiota and host physiological processes; however, the underlying metabolites remain elusiv…
The increasing infections caused by carbapenem-resistant Acinetobacter baumannii (CRAB) poses a serious threat to global public health. Antimicrobial peptides (AMPs) are alternatives to conventional antibiotics in combating superbugs. However, discov…
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…
Wound healing is a dynamic process involving distinct phases that are regulated by cellular and molecular interactions. This review explores the fundamental mechanisms involved in wound healing, including the roles of cytokines and growth factors wit…
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…
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…
