The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Psoriasis is an autoimmune disease of the skin with keratinocyte hyperproliferation and increased skin homing of immune cells. LL-37 is an antimicrobial peptide present at a high level in psoriasis patients. It is thought to participate in the induct…
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…
, 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…
Antimicrobial peptides (AMPs) play a crucial role in immune defense and wound healing. Their expression and function in pleural fluids following different thoracic surgeries remain underexplored. This study aims to compare AMP and cytokine profiles i…
This study develops a cobalt porphyrin-based hydrogen-bonded organic framework (Co-HOF) to scavenge reactive oxygen species (ROS) and target the pathogenic peptide LL-37, thereby disrupting psoriasis progression.
Sepsis and septic shock are major complications of febrile neutropenia (FN) in pediatric patients with cancer (PPCs). The aim of the present study was to determine the association of vitamin D (VD) and cathelicidin levels with sepsis and septic shock…
The interactions between peptides and lipids are fundamental for many biological processes. Therefore, exploring the noncovalent interactions that govern these interactions has become increasingly important. Native mass spectrometry is a valuable tec…
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.…
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…
Cathelicidins are a family of cationic antimicrobial peptides that play a critical role in innate immune defense. Like other antimicrobial peptides, cathelicidins can effectively kill pathogens while minimizing the risk of promoting antimicrobial res…
Ozone-induced inflammation has been linked to the development of skin ailments including atopic dermatitis, acne vulgaris, eczema and psoriasis, mainly through a redox-inflammatory pathway. While ozone cannot penetrate the cutaneous layers, it is abl…
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…
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…
Biomarkers are necessary tools to validate the diagnosis of Alzheimer's and Parkinson's diseases (AD and PD), especially when clinical symptoms are less apparent in the early stages of diseases. Current biomarkers used in clinical practice rely on br…
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…
Colorectal cancer (CRC) remains a major global health challenge, with increasing incidence and limited treatment options. The antimicrobial peptide cathelicidin (LL-37) has been implicated in both tumorigenic and tumor-suppressive roles, but its prec…
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…
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…
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…
