BACKGROUND: Little information is available regarding vitamin D-associated factors in patients with non-tuberculous mycobacteria (NTM) lung disease. OBJECTIVE: To determine the association between vitamin D-related factors and susceptibility to NTM l…
LL-37, a cationic antimicrobial peptide, has numerous immune-modulating effects. However, the identity of a receptor(s) mediating the responses in immune cells remains uncertain. We have recently demonstrated that LL-37 interacts with the αI-domain o…
Antimicrobial peptides are an ancient family of molecules that emerged millions of years ago and have been strongly conserved during the evolutionary process of living organisms. Recently, our group described that the human antimicrobial peptide LL-3…
A large number of antimicrobial peptides (AMPs) acts with high selectivity and specificity through interactions with membrane lipid components. These peptides undergo complex conformational changes in solution; upon binding to an interface, one major…
BACKGROUND: Although promising for graft-versus-host disease (GvHD) treatment, MSC therapy still faces important challenges. For instance, increasing MSC migratory capacity as well as potentializing immune response suppression are of interest. For Gv…
The hygiene hypothesis postulates that higher levels of cleanliness and improper exposure to microorganisms early in childhood could disturb the intestinal microbiome resulting in abnormal immune responses. Recently, more attention has been put on ho…
Tuberculosis (TB) is a major global health problem. Patients with TB have a high rate of vitamin D deficiency, both at diagnosis and during the course of treatment with anti-tuberculosis drugs. Although data on the efficacy of vitamin D supplementati…
There is consensus that inflammatory bowel diseases (IBDs) are the result of "dysregulated" immune reactivity towards commensal microorganisms in the intestine. This gut microbiome is clearly altered in IBD, but its primary or secondary role is still…
Clostridium difficile infection (CDI) is the most common cause of infectious diarrhea and represents an important burden for healthcare worldwide. Symptoms of severe CDI include watery, foul-smelling diarrhea, peripheral leucocytosis, increased C-rea…
The molecular pharmacology of the G protein-coupled receptors for sphingosine 1-phosphate (S1P) provides important insight into established and new therapeutic targets. A new, potent bitopic S1P3 antagonist, SPM-354, with in vivo activity, has been u…
The crude polysaccharide (KPV-0) isolated from Korean persimmon vinegar was fractionated using gel filtration chromatography to enhance the immunostimulatory activity and to identify the structural features of active fraction. Among three fractions,…
BACKGROUND: Tracheal intubation using acute-angle videolaryngoscopy achieves high success rates, but is not without difficulty. We aimed to determine predictors of 'difficult videolaryngoscopy'. METHODS: We performed a secondary analysis of a data se…
OBJECTIVE: To reveal the characteristics of anatomical and mechanical axes in lower extremities by analyzing full length weight bearing X ray radiographsin patients with knee osteoarthritis(OA). METHODS: From June 2015 to May 2016, the lower extremit…
BACKGROUND: Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed wh…
Oxidative stress causes mitochondrial impairment, the failure of energy production, and consequent organ dysfunctions. The aim of the present study was to investigate the potential therapeutic effects of mitochondrial antioxidant SS-31 on sepsis-indu…
OBJECTIVE: The aim of this study was to evaluate the influence of Th17 polymorphisms on the susceptibility or severity of rheumatoid arthritis (RA) and Sjögren's syndrome (SS). MATERIALS AND METHODS: The study sample comprised 206 individuals of both…
AIMS: Among patients with ST-elevation myocardial infarction (STEMI), reperfusion injury contributes to additional myocardial damage. MTP-131 is a cell-permeable peptide that preserves the integrity of cardiolipin, enhances mitochondrial energetics,…
Trauma is the most common cause of mortality among individuals aged between 1 and 44 years and the third leading cause of mortality overall in the US. In this study, we examined the effects of trauma on the expression of genes in Drosophila melanogas…
Oxidative stress is implicated in the pathogenesis of diabetic kidney injury. SS-31 is a mitochondria-targeted tetrapeptide that can scavenge reactive oxygen species (ROS). Here, we investigated the effect and molecular mechanism of mitochondria-targ…
BACKGROUND: Elamipretide (MTP-131), a novel mitochondria-targeting peptide, was shown to reduce infarct size in animals with myocardial infarction and improve renal function in pigs with acute and chronic kidney injury. This study examined the effect…
