The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
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…
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…
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis (Mtb) and is a growing public health problem worldwide. Within the innate immune response, we highlight the secretion of the antimicrobial peptide LL-37, which is crucial for…
BACKGROUND: Previous studies have shown that bioactive molecules secreted by toad skin possess anticancer properties. Cathelicidin-DM (C-DM) is a bioactive peptide secreted by toad skin, but its effects on tumor cells and the underlying molecular mec…
Osteomyelitis, a severe bone infection, poses a significant therapeutic challenge in both human and veterinary medicine, especially due to the increasing prevalence of antibiotic-resistant pathogens like methicillin-resistant Staphylococcus aureus (M…
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…
Lacticaseibacillus paracasei cell wall presents two capsular polysaccharides, CPS-1 and CPS-2, and a teichoic acid. CPS-1 is novel and it presents a branched heptasaccharide repeating unit, with the sequence →6)-α-d-Gal-(1→3)-β-l-Rha-(1→4)-β-d-Glc-(1…
The lysosomal cysteine protease cathepsin S supports host defence by promoting the maturation of MHC class-II proteins. In contrast, increased cathepsin S activity mediates tissue destructive immune responses in autoimmune and inflammatory diseases.…
BACKGROUND: The escalating global threat of antimicrobial resistance (AMR) necessitates the development of novel antimicrobial agents, innovative strategies, and representative infection models to combat AMR bacterial infections. Host defence peptide…
A vicious cycle between microbiota dysbiosis and hyperactivated inflammation, hardly disrupted by conventional therapies, remains a significant clinical challenge for periodontitis treatment. Herein, by cloaking a cascade catalysis system in an engin…
Cathelicidin-DM and cathelicidin-BG are homologous and are expected to be similar in structure and biological activity. However, while all structural prediction tools tested showed cathelicidin-BG to be helical, there were mixed results for cathelici…
INTRODUCTION: is a major human nosocomial infectious agent and an important veterinary pathogen, frequently resistant to various antibiotics. It causes diseases such as pneumonia, urinary tract infections, surgical wound infections and septicemia. Bi…
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…
BACKGROUND: Colorectal cancer (CRC) remains a major global health challenge, with increasing incidence, particularly among individuals under 50 years of age. Cathelicidin LL-37, a multifunctional antimicrobial peptide, has shown promise in cancer tre…
Chronic spontaneous urticaria (CSU) is a significant clinical condition characterized by an undetermined etiology, with some of its manifestations being attributed to immunological factors. The antibacterial properties of the cathelicidin leucine-leu…
Antimicrobial peptides (AMPs) have the potential to treat multidrug-resistant bacterial infections. Cathelicidins are a class of cationic antimicrobial peptides that are found in nearly all vertebrates. Herein, we determined the mature peptide region…
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…
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…
Helminths can manipulate their host's gut microbiota, with the expansion of the lactobacilli population being a common feature. This process profoundly influences host immunoregulation, yet the underlying mechanisms remain almost unknown. Using a tis…
UNLABELLED: Autoimmune skin diseases, such as psoriasis are primarily characterized by excessive inflammation and skin barrier damage. The disrupted skin barrier is directly related to skin dryness. Luteolin, a flavonoid compound, has various biologi…
