The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Pemphigus foliaceus (PF) is a multifactorial skin disease. Substantial evidence for microbiota dysbiosis in skin disorders was gradually revealed. In PF patients' skin lesions, we characterized the profile of microbial communities and the expression…
INTRODUCTION: The emergence of antibiotic-resistant pathogens is a significant global health concern that necessitates the development of new antimicrobial drugs. Due to its broad-spectrum action against bacteria, fungi, and viruses, human cathelicid…
The bidirectional correlation between diabetes and periodontitis positions the latter as the most prevalent complication of the former. Rehabilitation of the periodontal tissues damaged by diabetic periodontitis presents a significant clinical challe…
Rosacea is a chronic inflammatory skin disorder linked to the antimicrobial peptide LL-37 and immune cells. STING, a key DNA-sensing adaptor, initiates innate immune responses, with excessive activation contributing to inflammation. This study invest…
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…
Psoriasis is an immune-mediated inflammatory disorder, where the majority of the patients suffer from psoriasis capitis or scalp psoriasis. Current therapeutics remain ineffective to treat scalp lesions. In this study, we present a whole-metagenome c…
Marine organisms are a valuable source of natural bioactive substances, and an increasing number of marine antimicrobial peptides as the potential alternative to antibiotics are being developed. Nonetheless, antimicrobial peptides from Antarctic mamm…
Bacterial extracellular vesicles (BEVs) have emerged as a promising therapeutic platform, offering the potential to be engineered for targeted molecular delivery. In this study, the human cathelicidin antimicrobial peptide (LL37) was encapsulated int…
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…
BACKGROUND: Diabetic foot ulcers (DFUs) represent a common and serious complication of diabetes, characterized by impaired wound healing and an increased risk of infection. These infections severely impact patient health, necessitating extensive medi…
Tuberculosis (TB), caused by(MTB), remains one of the most devastating infectious diseases worldwide, with rising multidrug resistance limiting the effectiveness of conventional treatments. Novel therapeutic approaches are urgently needed to compleme…
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.…
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…
OBJECTIVE: To assess the feasibility of gene expression profiling of platelets in dogs with sepsis. METHODS: This was a prospective observational feasibility study conducted at a university veterinary teaching hospital. All study dogs had CBCs and se…
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…
Marijuana, an emerging risk factor for periodontitis, contains multiple potent antibacterials, particularly the phytocannabinoids. Microbial dysbiosis is a hallmark of this destructive oral disease. We examined a panel of oral bacteria for susceptibi…
Rosacea is a chronic inflammatory skin disorder of multifactorial pathogenesis, in which dysregulated innate immunity, neurovascular dysfunction, oxidative stress, and microbiome imbalance are central contributors. Recent molecular studies have revea…
BACKGROUND: Information about the association of antimicrobial peptides with hypovitaminosis D in hospitalized foals is lacking. HYPOTHESIS/OBJECTIVES: We aimed to longitudinally determine the association of serum concentrations of vitamin D metaboli…
Non-canonical functions of olfactory receptors, one of the largest families of GPCR receptors not confined to the olfactory system, include an intriguing role on hair physiology. Previous studies using odorant agonists of the Olfactory Receptor famil…
INTRODUCTION: The constantly growing resistance of bacteria causing bloodstream infections and the lack of alternative antibiotics generate the need to develop new therapeutic strategies. In this study, the antibacterial properties of synthetic choli…
