The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
Cathelicidin 3 (CATHL3), a member of the cathelicidin family, exhibits potent resistance against a spectrum of microorganisms. Despite its importance, the expression pattern and regulatory mechanisms of CATHL3 in inflamed dairy mammary glands remain…
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 The study examined and compared the significance of sociodemographic, oral health behavior, and maternal factors, as well as salivary pH and salivary levels of human neutrophil peptide 1 (HNP-1), human b defensin 2 (hBD-2), and human cathe…
INTRODUCTION: Cathelicidins are a family of antimicrobial peptides well-known for their antimicrobial and immunomodulatory functions in eutherian mammals such as humans. However, cathelicidins in marsupials, the other major lineage of mammals, have r…
BACKGROUND: Diabetic urinary incontinence is a multifactorial condition involving neuropathy, oxidative stress, and epithelial dysfunction. Serum biomarkers-cathelicidin (LL-37), elafin, vitamin D receptor (VDR), 4-hydroxynonenal (4-HNE), and amyloid…
The skeletal muscle interstitial space is the extracellular region around myofibers and mediates cross-talk between resident cell types. We applied a proteomic workflow to characterize the human skeletal muscle interstitial fluid proteome at rest and…
With antibiotic resistance being a major global concern, there is a huge need of new treatment options to fight bacterial infections. In this study, we highlight the antibacterial and host-protective roles of a novel synthetic antimicrobial peptide i…
OBJECTIVE: Gut microbiota dysbiosis induced by antibiotic use weakens its colonization resistance against opportunistic pathogens, increasing the risk of invasion and infection. While probiotics have the potential to restore the impaired gut microbia…
Brachymystax lenok is an economically valuable cold-water fish species that has shown lower morbidity during pathogen outbreaks compared to other cold-water species. To elucidate the innate immune mechanisms in B. lenok in response to Aeromonas salmo…
Cathelicidin-BF (CatBF) is a LL-37 homologous antimicrobial peptide (AMP) isolated fromwith an exceptional portfolio of antimicrobial, antiviral, antifungal, and anticancer activities. Contrary to many AMPs, it showed a good pharmacological profile w…
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…
The human antimicrobial peptide LL-37 exhibits broad antimicrobial efficacy. However, it has several limitations including high production costs, reduced efficacy under physiological conditions, susceptibility to proteolytic degradation and significa…
We aimed to clarify antimicrobial component (AMC) dynamics during the dry period in dairy cows and determine the impacts of varying somatic cell count (SCC) at the onset of the dry period on the subsequent changes in AMC concentrations in milk. Milk…
Isothermal titration calorimetry (ITC), circular dichroism (CD) spectroscopy, and molecular dynamics simulations were applied to describe interactions between lipopeptides and decavanadate ions ([VO]). The selected lipopeptides are conjugates of 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…
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…
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…
Lytic transglycosylase A in Neisseria gonorrhoeae cleaves the β-1,4-glycosidic bond between peptidoglycan (PG) monomers to liberate 1,6-anhydro-PG fragments that are either recycled or released as cytotoxic fragments. To gain further insight into the…
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…
