The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Malaria control is challenged by the emergence of resistance to virtually all antimalarial drugs, from the frontline artemisinin to other classes, highlighting the critical need for new therapies. This study demonstrates that the human antimicrobial…
OBJECTIVE: This study aimed to elucidate the molecular mechanisms through which CXCL2 contributes to the pathogenesis of idiopathic interstitial pneumonia (IIP). METHODS: Neutrophils were isolated, and the formation of neutrophil extracellular traps…
Effective management of infected skin wounds remains a major clinical challenge, particularly as rising antibiotic resistance compromises conventional therapies. Antimicrobial peptides (AMPs) have emerged as promising alternatives, but their clinical…
BACKGROUND: Respiratory, gastrointestinal, and allergic diseases can significantly affect children's physical and mental health and quality of life. PURPOSE: This study aimed to assess the safety of Bifidobacterium animalis subsp. lactis BLa80, its p…
The gastrointestinal mucus barrier (GIMB) is a gelatinous structure consisting primarily of mucins, water, and cathelicidin. Such a structure is the first line of defense against pathogens in the intestinal cavity and acts an important environment fo…
The emergence of drug resistance and host toxicity is associated with conventional antiprotozoal therapies which necessitates development of novel and selective antiparasitic agents. In the present study, novel hybrid peptide which is HP-AP-1 (KRIVQR…
BACKGROUND: The evidence of a low-biomass microbial community in the amniotic fluid (AF) is challenging the traditional concept of a sterile womb. To clarify microbial presence and host responses, a comprehensive, multi-methodological approach is req…
INTRODUCTION: Elevated levels of serum Vitamin D (VitD) and increased expression of its receptor on peripheral blood cells have been reported in individuals who have been exposed to HIV-1 yet remain seronegative (HESN). This study aimed to investigat…
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…
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…
Cathelicidin is a family of antimicrobial peptides in vertebrates that plays an important role in resistance and immunization against pathogenic microorganisms. In the present study, the full-length cDNA sequences of four novel cathelicidins (catheli…
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: 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…
Infections after psychological stress are a major health care problem. Single-cell transcriptomics and lipidomic profiling in a mouse model of stress show that dermal fibroblasts undergoing adipogenesis have defective responses toskin infection. Adre…
BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is associated with high rates of treatment failure, even when antibiotics showing in vitro susceptibility are used. Early optimization of therapy is crucial to reduce morbidity…
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…
In addition to its classical role in calcium and phosphate metabolism regulation, vitamin D also has an important impact on immunity modulation. Vitamin D regulates the immune response, shifting from a proinflammatory state to a more tolerogenic one…
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…
Escalating antimicrobial resistance necessitates the development of alternative therapeutics that circumvent conventional enzymatic and efflux-based defence systems. Antimicrobial peptides (AMPs) represent a compelling class of innate immune effector…
Human cathelicidin LL-37 is a promising antibacterial agent; however, conventional administration routes limit its efficacy. This study aimed to develop cetyl palmitate (CP)-based lipid nanoparticles loaded with LL-37 peptide (LL) for pulmonary deliv…
