Rosacea is a chronic inflammatory skin condition characterized by persistent erythema and abnormal vascular response. Although current treatments focus on symptomatic relief, they often provide only temporary improvement and may be associated with si…
The oral epithelium is essential for maintaining oral health and plays a key role in the onset and progression of periodontitis. It serves as both a mechanical and immunological barrier and possesses antimicrobial activity. Vitamin D, a hormone with…
INTRODUCTION: Monoosteophils, derived from LL-37-treated monocytes, are a novel type of calcifying/bone forming cells. We have shown that monoosteophils can form bone-like nodulesand accelerate bone repair in a drilled femur defect model. Here, we ex…
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…
Colonic goblet cells play a crucial role in mucosal defense by secreting Muc2 mucin and other proteins that entrap and expel enteropathogens. However, the role of innate effectors in the gut like cathelicidin peptides in regulating the mucus barrier…
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…
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…
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…
Hypoxia is a considerable challenge for the prawn culture, especially in high-density intensive aquaculture. The giant freshwater prawn, Macrobrachium rosenbergii, is an economically important species in Asia and South America. However, M. rosenbgerg…
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…
BACKGROUND: Non- specific low back pain (NSLBP) is a common musculoskeletal disorder that leads to disability. Its development has been associated with inflammatory responses including cytokines such as TNF-α. Various management approaches, including…
AIMS: This study aims to develop novel antibacterial agents by targeting SufA protease, a key virulence factor in Finegoldia magna, using 1-aminoalkylphosphonate (1-AAP) diaryl esters as inhibitors. MATERIALS & METHODS: Structural optimization of a r…
: Infections caused by multidrug-resistant (MDR)are steadily increasing, thus the discovery and development of new and effective agents are needed. Antimicrobial peptides (AMPs) are a heterogeneous group of innate defense system peptides with broad a…
species are often the cause of implant-related infections, posing a significant clinical challenge in orthopedics. Antimicrobial peptides (AMPs) like LL-37-derived FK-16 and GF-17 offer promising alternatives to conventional antibiotics; however, the…
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…
Cathelicidins are a family of antimicrobial peptides (AMPs) with broad-spectrum activity and immunomodulatory functions. Among them, the only human cathelicidin LL-37 has garnered significant interest due to its potent antimicrobial, antiviral, antif…
The liver fluke Opisthorchis viverrini causes chronic infections in humans and animals. This helminth is known to coexist with the bacterial microbiome in the host's bile duct, and their interaction potentially impacts the helminth's pathogenicity. W…
Candida glabrata (currently classified as Nakaseomyces glabratus) is an opportunistic yeast-like fungus that causes infections in humans, with limited treatment options due to resistance to antifungal drugs. In contrast to C. albicans, which produces…
Cathelicidin LL-37, an antimicrobial peptide (AMP) of the innate immune system, wards off bacterial infections. Recent research has identified plenty of biological functions of AMPs beyond their antimicrobial activity, including antioxidant, self-ren…
LL-37 and its variants with amphiphilic structure can modulate amyloid-β (Aβ) fibril formation, but the detailed mechanism behind it is still unclear. By using four different peptides (LL-37, LL-37, LL-37, LL-37), we found these peptides affect Aβ40…
