Host Defense Peptides (HDPs) such as cathelicidins are multifunctional effectors of the innate immune system with both antimicrobial and pleiotropic immunomodulatory functions. Chicken cathelicidin-2 (CATH-2) has multiple immunomodulatory effects in…
In addition to killing pathogens and influencing immunological processes, cathelicidin LL-37 is a multifunctional host defense peptide with a role in homeostasis. It has been suggested that imbalances in homeostatic signaling from inflammatory/ immun…
Rosacea is one of the most common dermatoses of adults. Although the detailed pathophysiology remains unknown, it is thought that rosacea is caused by a consistently aberrant, innate immune response, and that LL-37 plays an important role. However, i…
Bacterial infection commonly occurs in clinical settings when the procedure involves a medical implant. Thus, the fabrication of antimicrobial medical materials has attracted much attention in recent years. To improve the antibacterial properties of…
Multidrug-resistant bacterial strains are a rapidly emerging healthcare threat; therefore it is critical to develop new therapies to combat these organisms. Prior antibacterial strategies directly target pathogen growth or viability. Host-directed st…
One of the greatest merit of the use of radiopeptides in oncology is their selectivity which, however, brings about the drawback that each radiopeptide is specific for a given tumor type. To overcome this problem the direction currently taken in drug…
BACKGROUND AND AIMS: Vitamin D signaling is involved in infectious and non-infectious liver diseases, yet the natural vitamin D metabolites are suboptimal therapeutic agents. In the present study, we therefore aimed to explore the potential and mecha…
Respiratory viral infections cause mild to severe diseases, such as common cold, bronchiolitis and pneumonia and are associated with substantial burden for society. To test new molecules for shortening, alleviating the diseases or to develop new ther…
Despite the discovery of key pattern recognition receptors and CD4+ T cell subsets in laboratory mice, there is ongoing discussion of the value of murine models to reflect human disease. Pneumocystis is an AIDS-defining illness, in which risk of infe…
The hybrid peptide cecropin A (1⁻8)⁻LL37 (17⁻30) (C⁻L), derived from the sequence of cecropin A (C) and LL-37 (L), showed significantly increased antibacterial activity and minimized hemolytic activity than C and L alone. To obtain high-level product…
To investigate the effect and molecular mechanism of antimicrobial peptide LL-37 secreted by stromal cells on the growth of colorectal cancer cells.Colorectal cancer cells SW480 or HCT116 were co-cultured with human macrophages using Transwell(®) max…
Clostridioides (Clostridium) difficile causes severe diarrheal disease that is directly associated with antibiotic use and resistance. Although C. difficile demonstrates intrinsic resistance to many antimicrobials, few genetic mechanisms of resistanc…
BACKGROUND: Acute myocardial infarction (MI) and the ensuing ischemic heart disease are approaching epidemic state. Unfortunately, no definitive therapies are available and human regenerative therapies have conflicting results. Limited stem cell rete…
OBJECTIVES: Previous studies demonstrated associations between reduced serum 25-hydroxyvitamin D (25OHD), inflammation and disease activity in paediatric systemic lupus erythematosus (pSLE). The goal of this study was to assess parathyroid hormone (P…
BACKGROUND: The immune system depends on effector pathways to eliminate invading pathogens from the host in vivo. Macrophages (MΦ) of the innate immune system are armed with vitamin D-dependent antimicrobial responses to kill intracellular microbes.…
A large body of data demonstrates that interferon regulatory factor 5 (IRF5) and nuclear factor kappa B (NF-κB) are the two major transcription factors in classically activated macrophages responsible for the transcriptional control of proinflammator…
AIM: The aim of this study was to develop a nanofiber-based dressing capable of local sustained delivery of 1α,25-dihydroxyvitamin D(1,25(OH)D) and augmenting human CAMP induction. MATERIALS & METHODS: Nanofibrous wound dressings containing 1,25(OH)D…
BACKGROUND: We have previously shown that 8 weeks' treatment with phenylbutyrate (PBA) (500mgx2/day) with or without vitamin D(vitD) (5000 IU/day) as host-directed therapy (HDT) accelerated clinical recovery, sputum culture conversion and increased e…
We performed the in silico genome-wide identification of antimicrobial peptides against the available genome sequence of the naked mole rat Heterocephalus glaber (H. glaber). Our results showed the presence of Hg-CATH, the single cathelicidin contain…
