The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
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…
Infections with the protozoancause abortion in cattle, likely due to the parasite's replication and excessive inflammation in the placenta. Cathelicidins are host defense peptides known for their antimicrobial and immunomodulatory functions, but thei…
Antimicrobial peptides (AMPs) represent a unique group of naturally occurring molecules having diverse biological activities, including potent antimicrobial properties. Among them, LL-37 has emerged as a significant player, demonstrating its multifac…
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…
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…
Ultraviolet (UV) radiation-induced skin photoaging impacts both appearance and skin health, potentially leading to disorders and cancer. Unlike traditional sunscreens, natural antioxidants can target photoaging at its source. Among these, cathelicidi…
BACKGROUND: The genetic modification of mesenchymal stromal/stem cells (MSCs) to express antimicrobial peptides may provide a promising strategy for developing advanced cell-based therapies for bacterial infections, including those caused or complica…
Osteoarthritis (OA) is the most prevalent form of joint arthritis, frequently associated with aging, mechanical wear, and inflammation. Our previous work demonstrated that cathelicidin-related antimicrobial peptide (Cramp) is upregulated in mouse OA…
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…
Implant-associated infections pose significant challenges due to bacterial resistance to antibiotics. Recent research highlights the potential of immobilizing antimicrobial peptides (AMPs) onto implants as an alternative to conventional antibiotics f…
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…
BACKGROUND: () is a gram-negative bacterial pathogen commonly associated with nosocomial infections. Treatment ofinfections is notoriously difficult due to biofilm formation and antibiotic resistance. Antimicrobial peptides (AMPs) are thought to be p…
, 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…
Cathelicidin-1, an antimicrobial peptide, has garnered attention for its potential role as a biomarker in detecting anestrus in cows, providing insights into bovine reproductive health. This study aimed to analyse cathelicidin-1 within the urinary pr…
The objectives of the present work were as follows: (i) the detection of cathelicidin biomolecules in the milk of individual goats during the early stages of mastitis and their potential use for the diagnosis of mastitis at its early stage and (ii) t…
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 AND AIMS: LL-37, an antimicrobial peptide with dual pro-/anti-inflammatory roles, has been implicated in the pathogenesis of periodontitis, yet its specific action through its receptor Formyl peptide receptor 2 (FPR2) remains unclear. Th…
BACKGROUND/OBJECTIVE: Antimicrobial peptides have demonstrated promise as biomarkers for urinary tract infection (UTI) in older adults (age ≥ 65 years). However, it is unknown if urinary AMP levels also increase in asymptomatic bacteriuria. Our objec…
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…
