Polyetherketoneketone (PEKK) is considered to be a potential substitute material for metal bone implants because of its advantageous biocompatibility, chemical stability, and mechanical properties, but clinical application has been severely restricte…

Human cathelicidin LL-37 is an antimicrobial peptide that has a broad spectrum of antimicrobial activities but also acts on host cells to exert immunomodulatory functions. It has been suggested that the increase of LL-37 in atherosclerotic aortas and…

Adipocytes from the superficial layer of subcutaneous adipose tissue undergo cyclic de- and re-differentiation, which can significantly influence the development of skin inflammation under different cutaneous conditions. This inflammation can be conn…

Myocardial infarction (MI) is one of the most common cardiac emergencies with high morbidity and is a leading cause of death worldwide. Since MI could develop into a life-threatening emergency and could also seriously affect the life quality of patie…

Rosacea is a chronic inflammatory skin disorder that manifests abnormal enhanced sensitivity to environmental stimuli. The decreased prevalence of rosacea in aged population has been reported, but the underlying mechanism is unclear. In this study, w…

PURPOSE: Although mast cells (MCs) modulate the activity of effector cells during Candida albicans infection, their role in the pathogenesis of candidiasis remains unclear. Candidalysin, a C. albicans-derived peptide toxin, is a crucial factor in fun…

The identification of practical early diagnostic biomarkers is a cornerstone of improved prevention and treatment of cancers. Such a case is devil facial tumor disease (DFTD), a highly lethal transmissible cancer afflicting virtually an entire specie…

BACKGROUND: Antimicrobial peptides (AMPs) have shown promise in the treatment of multi-resistant pathogens. It was therefore of interest to analyze the effects of the AMP LL-37 on the regulation of several virulence factors related to the quorum sens…

Staphylococcus aureus frequently causes infections that are challenging to treat, leading to high rates of persistent and relapsing infection. Here, to understand how the host environment influences treatment outcomes, we study the impact of human se…

Vitamin D is a key regulator in calcium and phosphorus metabolism which are essential for maintaining bone health. Recent reports also showed a role for vitamin D in immune regulation which may be linked to vitamin D deficiency in autoimmune disorder…

BACKGROUND: This study served as the pioneer in studying the anti-cancer role of chicken cathelicidin peptides. METHODS AND RESULTS: Chicken cathelicidins were used as anticancer agent against the breast cancer cell line (MCF-7) and human colon cance…

BACKGROUND: Ginseng has been used in Korea for a long time as a restorative herbal medicine. Black ginseng (BG) is made from red or white ginseng by multiple steamy and dry processes. Although BG has been reported to have anti-inflammatory potential,…

Tuberculosis (TB), which is caused by the bacterium(), is still one of the deadliest infectious diseases. Understanding how the host and pathogen interact in active TB will have a significant impact on global TB control efforts. Exosomes are increasi…

The development of antimicrobial agents against multidrug-resistant bacteria is an important medical challenge. Antimicrobial peptides (AMPs), human cathelicidin LL-37 and its derivative OP-145, possess a potent antimicrobial activity and were under…

Leprosy is an infectious disease influenced by genetic, immunological, and environmental factors. Reduced gene expressions may be associated with the immunological response pattern and leprosy susceptibility. We investigated the direct and indirect e…

B1-Leu peptide is a structural optimization compound derived from the lysine- and phenylalanine-rich antimicrobial peptide Cathelicidin-BF. It has shown promising antibacterial and antitumor biological activity. However, linear peptides are not the b…
