The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
OBJECTIVE: To investigate the diagnostic value of the T cell spot (T-SPOT.TB) test, oxidation-related factors (ORF), and antimicrobial peptide LL-37 in patients with pulmonary tuberculosis (PTB) with type 2 diabetes. METHODS: A total of 560 patients…
STUDY OBJECTIVES:: Pneumonia, chronic obstructive pulmonary disease (COPD), and heart failure (HF) exacerbations can present similarly in the older adult in the Emergency Department (ED), leading to sub-optimal treatment from over- and under-diagnosi…
Cell-penetrating peptides (CPPs) can transport various cargoes through membranes of live cells. Since the first generations of CPPs suffered from insufficient cell and tissue selectivity, stability against proteases, and escape from endosomes, a new…
Regulation of immune function continues to be one of the most well-recognized extraskeletal actions of vitamin D. This stemmed initially from the discovery that antigen presenting cells such as macrophages could actively metabolize precursor 25-hydro…
Endometritis is a common bacterial disease of dairy cows. Cathelicidins are host-defense peptides that play important roles in clearance of bacteria. However, the expression pattern of these peptides during endometritis is still unclear. We hypothesi…
Urinary tract infection frequently caused by E. coli is one of the most common bacterial infections. Increasing antibiotic resistance jeopardizes successful treatment and alternative treatment strategies are therefore mandatory. Metformin, an oral an…
Cathelicidins are an important antimicrobial peptide family and are expressed in many different vertebrates. They play an important role in the innate immune system of the host. However, amphibian cathelicidins are poorly understood. In this study, t…
Accumulating preclinical and clinical evidence indicates that high degrees of heterogeneity among malignant cells constitute a considerable obstacle to the success of cancer therapy. This calls for the development of approaches that operate - or enab…
Different types of biomaterials have been used to repair the defect of bony orbit. However, exposure and infections are still critical risks in clinical application. Biomaterials with characteristics of osteogenesis and antibiosis are needed for bone…
Viral pneumonias are a major cause of morbidity and mortality, owing in part to dysregulated excessive lung inflammation, and therapies to modulate host responses to viral lung injury are urgently needed. Protectin conjugates in tissue regeneration 1…
(1) Background: The cathelicidin peptide LL-37 is a prominent molecule with many biological activities, including antimicrobial. Due to its importance, here, we describe the production of LL-37 tagged with SmbP, a relatively new carrier protein that…
To explore whether glycosuria induces virulence of uropathogens, in turn facilitating urinary tract infection (UTI), we exposed group B Streptococcus (GBS) strain 10/84 to human urine plain or with 300 mg/dL glucose (mimicking moderate glycosuria). E…
Human hair follicles (HFs) carry complex microbial communities that differ from the skin surface microbiota. This likely reflects that the HF epithelium differs from the epidermal barrier in that it provides a moist, less acidic, and relatively ultra…
OBJECTIVE: The aim of this study was to explore the dose effect of bovine lactoferrin (bLF) fortification on the morbidity of diarrhea and respiratory tract infections in weaned infants with anemia. METHODS: A total of 108 infants with anemia, who we…
In this study, dodecapeptide cathelicidins were shown to be widespread antimicrobial peptides among theclade. In particular, we investigated the dodecapeptide from the domestic goat, designated as ChDode and its unique ortholog from the sperm whale(P…
The term host defense peptides arose at the beginning to refer to those peptides that are part of the host's immunity. Because of their broad antimicrobial capacity and immunomodulatory activity, nowadays, they emerge as a hope to combat resistant mu…
BACKGROUND: Fungal keratitis (FK) is the leading cause of unilateral blindness in the developing world. Antimicrobial peptides (AMPs) have been shown to play an important role on human ocular surface (OS) during bacterial, viral and protozoan infecti…
INTRODUCTION: Cathelicidin is a multifunctional host defense peptide which may also exert pro-inflammatory signals and contribute to the development of autoimmune disorders. We aimed to assess serum concentration of cathelicidin in children with infl…
Native mass spectrometry (MS) with nanodiscs is a promising technique for characterizing membrane protein and peptide interactions in lipid bilayers. However, prior studies have used nanodiscs made of only one or two lipids, which lack the complexity…
Several antimicrobial peptides, including magainin and the human cathelicidin LL-37, act by forming pores in bacterial membranes. Bacteria such as Staphylococcus aureus modify their membrane's cardiolipin composition to resist such types of perturbat…
